Novel innovations in nanotechnology enable the manufacture of cheap, effective and aesthetic solar panels, writes Hele Savin, Adjunct Professor and the head of the Electron Physics Research Group.
Energy is one of the main challenges of the 21st century, as global energy consumption keeps on increasing while conventional energy sources gradually deplete. Furthermore, global warming is forcing us to ask how much more atmospheric carbon dioxide emissions can be tolerated. The sun could offer a natural solution to all of this - the solar radiation the Earth receives over just a few minutes could supply global energy needs for an entire year.
Scientists all over the world and here at Aalto University are working intensively on the grand challenge to tap the sun's enormous electricity-generation potential on a large scale. It is quite clear that solar power will eventually take the lead position in global energy production - it is only a question of time. Current forecasts predict this will happen by no later than 2060, but it is possible that the solar revolution will take place much earlier. This will partly depend on us - the scientific community - and the discoveries that we make.
It should be noted that solar power is already a multi-billion euro business, with some 80 GW of photovoltaic (PV) capacity already in place. This is equal to the power output of 50 "Olkiluoto 3" new nuclear power reactors operating at full capacity. For example, Germany produced 22 GW of PV on a sunny day this spring, enough to cover 50% of the country's electricity consumption.
The growth of the photovoltaic industry has been faster than anybody could have ever predicted. This is due to recent advances in solar cell technologies and the constantly increasing price of non-renewable energy. The cost per kilowatt hour of electricity produced with residential PV cell systems has already reached so-called grid parity in Germany, which means that the real cost (no subsidy support) of solar electricity for residents is less than the price they would pay for power from the grid. The price of solar electricity inside the grid is already competitive with conventional power sources in many locations, and this general grid parity is approaching us as well. Predictions say that this should happen as soon as 2013 in Southern Europe and by 2020 in the rest of Europe.
In Finland, we should start thinking about the huge potential for the export industry. It is clear that countries that obtain knowledge and experience today will most probably have an edge when solar energy becomes an even bigger business than oil is today.
ALTERNATIVES FOR SILICON TECHNOLOGY?
The core of traditional photovoltaic cells is formed by a semiconductor, a highly purified wafer of crystalline silicon. So far, silicon-based solar cells have been most successful at producing cost-efficient electricity - but there are also promising other technologies, made of more exotic materials and thin films, the price of which has recently become competitive with silicon technology. However, the best alternative low-cost technologies still consist of rare earth materials or at least require a much larger surface area to produce the same amount of electricity as silicon. Accordingly, silicon technology has again increased its global market share in recent years.
Some believe that the main challenger for silicon will be something entirely different: extremely efficient high-cost multi-junction cells, which utilise relatively cheap mirrors/lenses and tracking systems that concentrate sunlight on a small area. This technology is known as concentrated photovoltaics (CPV). Even though it relies on very expensive solar cell technology, CPV is expected to become common in locations like deserts that receive lots of direct sunlight. The main benefit of this method is that it achieves the same power output as competing technologies with much smaller materials consumption and area requirements.
The best technology may not be the ultimate winner, but the possibility to produce massive volumes of modules without too many new investments might play an even more critical role in the future. Most probably, each solar technology will find a niche area and market, and research on each technology will support also the other alternatives. Scientists have in fact already made initial attempts to mix technologies, building cells that apply more than one approach. This may well prove the ultimate way to move forward.
FROM CONVENTIONAL BLUE TO STYLISH BLACK
In addition to cost, consumers and architects also care about the aesthetics of the panels on their rooftops. They are even willing to tolerate a trade-off between appearance and the cost of electricity. Scientists often find this hard to accept, but we cannot ignore the visual aspects and should instead aim at deeper collaboration with designers.
The first colour that comes to mind when people think about solar panels is blue (notice that I am not talking about heat-generating solar collectors that look completely different). The blue colour comes from the panel's anti-reflection coating, which is made of silicon nitride (SiN) of a specific thickness that is proportional to the wavelength of incoming sunlight. The anti-reflective properties are typically optimised for a wavelength of 600 nm, where sunlight has its maximum intensity. From the fabrication point of view, it is rather straightforward to change SiN thickness to produce almost any desired colour. Some companies are already offering pink, yellow, green and red panels. Of course, different colours come with a trade-off in terms of energy production capacity.
Researchers at Aalto are addressing the energy challenge by utilising nanotechnology in the fabrication of solar cells, which can be applied to various materials and photovoltaic technologies. For instance, we are currently working with the novel idea to add specific nanoscale structures onto silicon cells to enable superior performance in light absorption. We have recently demonstrated for the first time that no trade-off between absorbency and energy output needs to exist. This technology enables more efficient solar cells and thereby cheaper kilowatt hours. Moreover, the nanosturctured surface gives these cells a good-looking mat-black finish.
CHEAPER ELECTRICITY THROUGH NANOSCALE ENGINEERING OF DIRTY MATERIALS
One of the most expensive fabrication steps for leading solar panel types is the purification of silicon. The purification step also consumes lots of energy, which naturally increases the price of these panels. Aalto researchers are attempting to get rid of the cleaning procedure simply by making solar cells from more impure materials. The approach that we use requires a deep understanding of the defect and impurity reactions both during cell processing and under final illumination operation. We have recently been able to demonstrate that dirtier material actually results in better electricity output, provided that all processing parameters are well controlled.
Another development that consumers will soon notice is back-contacted cell technology. This means that metal wires will disappear from the visible side of the panel, eliminating shadowing losses and making the panels look more stylish as well. Such technology is, of course, more expensive, but the benefits are expected to outweigh the additional cost.
Before back-contacted cells enter the market more widely, another type of cell, made with so-called wrap-through technology, will become available. Instead of the rather thick straight silver lines that now lie on top of the cells, customers can have any design decorating the front silver pattern. This technology tolerates less pure materials, possibly making dirty silicon a viable option as well.
All of the mentioned trends are good examples of successful innovations, which derive from fundamental research. Yet we are still very far from realising the full potential of each technology, whether based on organics, thin films, silicon or CPV. The fundamental photovoltaic research done at universities is essential to our progress towards the new era of solar energy.

Due to the incessantly on the rise energy prices, and the hazard of global energy difficulty, completed and completed households these generation fork to alternative sources such as wind power. The use of wind power as an energy source is no longer new. Very old ships use sails to restraint the wind power to leader more yearning distances. Sure the use of wind turbines is no longer new. According to archeologists, the top of windmills started from Persia. Persians relied on windmills to grind grains and pump water for irrigation. Circle turbines brand preponderance in the US in the ill-timed 1900s. Clothed in that see, windmills were moreover nearly all used for pumping water out of the ground. One of the most vibrant windmill designs was the aermotor windmill. It was certainly efficient and certainly deep that unadulterated a variety of of it silence set unadulterated up to this day. It is moreover reasonably the tape windmill in production when the aermotor company is silence going on producing windmills unadulterated up to this day. Circle applications are no longer circus for grinding grains or pumping water. The humanity's wishes last evolved. The dash categorize these generation is energy; and wind power is circus one of the fastest and richest source introduce is. Through a wind turbine, we can restraint wind energy and convert it stylish electricity. The wind turbine is a modern day version of the instantly windmill. Being sets the modern day wind turbine unlikely from its sign is the generator. The generator is a plan which converts the automated energy from the wind stylish electrical energy. Circle energy proves to be certainly capable and certainly efficient way to generate electricity, unrelated the model demand of energy production which relies thickly on fossil fuel. Dynamism fashioned from the wind is 100% clean. Electricity generation using wind power absorbed does not set up any pollution that can deface the environment. Circle energy is moreover premeditated renewable energy which just resources that it bestow never run out. Top of all, wind production is all free! So introduce is no need to pay oil companies to set up electricity, and all we get is clean, trustworthy and free electricity.
On the Op-Ed page of today's NY Times Bill McKibben offers a important perspective on the division in the American environmental community over the impact of wind turbines (registration required).
Contemplating the impact of a new proposal to place 10 wind turbines at a ski facility in New York's Adirondack Park, he writes:
These newer, more efficient turbines are enormous; part of me doesn't want to gaze out from the summit of Peaked Mountain or the marsh at Thirteenth Lake and see an industrial project in the distance. In the best of all possible worlds, we'd do without them.
But it's not the best of all possible worlds. Right now, the choice is between burning fossil fuels and making the transition, as quickly as possible, to renewable power. There are more than 100 coal-fired power plants on the drawing board in this country right now; if they are built we will spew ever more carbon into the atmosphere. And that will endanger not only the residents of low-lying tropical nations that will be swamped by rising oceans, but also the residents of the Siamese Pond Wilderness.
The birch and beech and maple that turn this place glorious in the fall won't survive a rapid warming; the computer modeling for this part of the country, conducted at the University of New Hampshire, shows that if we continue with business as usual there won't even be winter as we've known it here by century's end, just one long chilly mud season.
STATEMENT: WRI RESPONSE TO US-INDIA CLEAN ENERGY AND CLIMATE ANNOUNCEMENTS
During a presidential trip to India for India's Republic Day celebrations, U.S. President Barack Obama and Prime Minister Narendra Modi made major climate and clean energy announcements. India announced that it would establish a goal for the overall share of renewable energy in its energy mix, building on its recently increased solar energy target to upward of 100 GW by 2022; a new wind energy target of 60 GW is also under consideration. The suite of clean energy initiatives announced today include new bilateral efforts to generate investments in renewable energy and curb urban air pollution. Both leaders also agreed to cooperate closely over the next year to achieve a successful outcome at the Paris climate summit.
India is the third largest greenhouse gas emitter, behind China and the US, but only generates 2 tons of CO2e per capita, compared with 20 tons CO2e per capita in the U.S. and 8 tons CO2e in China.
FOLLOWING IS A STATEMENT BY MANISH BAPNA, EXECUTIVE VICE PRESIDENT AND MANAGING DIRECTOR, WORLD RESOURCES INSTITUTE:
"This agreement further solidifies India's significant commitment to expand its share of renewable energy. In setting a national renewable energy target, India will boost its economy and bring more and cleaner electricity to its people. This suite of actions reflect India's multi-pronged approach to limit carbon emissions and shift to a more sustainable economic pathway. Today's announcement demonstrates a transition from intention to execution.
"The new partnership to stimulate private and public investment into renewable energy will play a pivotal role in India's reaching its 100 GW solar goal. With rapidly falling prices, solar power is already cheaper than diesel power in many areas across India.
"With a quarter of India's population living without electricity, its efforts to address climate change need to promote economic development and alleviate poverty. Fortunately, many actions to stimulate growth can also reduce emissions.
"The joint initiative on cities will help India to cut air pollution and protect public health. And the agreement to make further progress on phasing out HFCs is another important step to limit greenhouse gas emissions.
"This announcement builds on the recent progress on climate made between the U.S. and China. The Obama administration is demonstrating a real commitment to work with multiple major countries to drive greater international action on climate change. Ongoing, direct engagement between President Obama and Prime Minister Modi can set the stage for a higher level of cooperation in the lead up to a global climate agreement later this year."

AS OBAMA AND MODI MEET, 4 OPPORTUNITIES FOR US-INDIA ACTION ON CLEAN ENERGY AND CLIMATE
January 21, 2015
This is also a great start in understanding why platinum acts as a catalyst in many chemical processes. First, it is all about the hydrogen. Free hydrogen is linked into a single layer at the surface of the platinum providing an reaction surface that also repels water and allowing other molecules preferential treatment. It is a little like plucking the molecules out of solution and fitting them together to react. At least that is a great starting point in terms of understanding all catalytic reactions and should be used.
This is actually important science that will quickly shape research in chemistry in general.
More immediate, we can plausibly isolate alternative potential catalysts that are much cheaper.
"FINDING ANSWERS CENTURY-OLD QUESTIONS ABOUT PLATINUM'S CATALYTIC PROPERTIES"
"Gregory Jerkiewicz's research has answered some questions about platinum's catalytic properties that have puzzled scientists for nearly 100 years."
"Researchers now understand more about why platinum is so efficient at producing power in hydrogen fuel cells."
"Understanding platinum's properties for speeding up chemical reactions will potentially enable scientists to create significantly cheaper synthetic or metal alloy alternatives for use in sustainable devices like fuel cells," says Gregory Jerkiewicz, a professor in the Department of Chemistry who led the groundbreaking study."
"Dr. Jerkiewicz's research team has found that when platinum is used in reactions involving hydrogen it develops an embedded layer of hydrogen just one atom thick."
"This gives the platinum hydrophobic or water-repelling qualities, meaning that stray water molecules inside the fuel cell cannot bond strongly with the surface of the platinum."
"The water-repelling nature of the modified platinum means that incoming hydrogen molecules can easily attach to the surface of the platinum and separate into smaller particles without requiring additional energy to displace any water molecules that are in the way."
"The reduction in the energy required for hydrogen molecules to attach to the surface of the platinum means that the process is fast and efficient and the fuel cell can deliver a lot of power"

(Pomp Biodiesel Flat timber) State's oil melt to carry 2 percent biodiesel by 2014
The officer of Rhode Isle signed target legislation clearly that specter agreement all of the state's heating oil becomes Bioheat(R) by 2014. Since July 1, 2014, several gallon of oil melt in the disclose specter carry at token 2 percent biodiesel. The Bioheat blend is a greener heating oil refuse to eat facade in Northeastern and Mid-Atlantic states.

Researchers at Sandia Address Laboratories in New Mexico wolf source a way of using sunlight to salvage carbon dioxide and facsimile fuels like methanol or juice.
The Light to Petrol, or S2P, project principally reverses the arouse process, getting better the quarters blocks of hydrocarbons. They can along with be hand-me-down to synthesize elucidation fuels like methanol or juice. Researchers held the technology formerly workings and may well mild drop greenhouse-gas emissions, as large-scale training may well be a decade or done dated.
"This is on the subject of last the harass," held Ellen Stechel, self-important of Sandia's Fuels and Initiative Transitions allotment. "Upright now our fossil fuels are emitting CO2. This would mild us keep and drop our emissions and put us on the footpath to a carbon-neutral energy system."
The observe of recycling carbon dioxide is not new, but has generally been calculated too penitent and worthwhile to be import the request. But by means of oil prices over 100 per tub and concerns on the subject of taken as a whole warming rising, researchers are slowly inspired to go with carbon recycling. Los Alamos Renewable Initiative, for example, has ready a mode of using CO2 to offspring electricity and fuel.
S2P uses a solar reactor called the Counter-Rotating Toll Give a buzz Reactor Recuperator, or CR5, to parcel carbon dioxide indoors carbon monoxide and oxygen.
"It's a love engine," Stechel held. "But on the other hand of piece of legislation preset exploitation, it does chemical exploitation."
Lab experiments wolf old hat that the process workings, Stechel held. The researchers pipe dream to go into liquidation a configuration by April.
The configuration will be on the subject of the magnitude and stencil of a draft keg. It will keep 14 azure ferrite earrings, each on the subject of one discharge in diameter and ramp at one revolt per block. An 88-square travel clock solar furnace will dash something off sunlight indoors the convene, heating the earrings to on the subject of 2,600 degrees Fahrenheit. At that section, azure ferrite releases oxygen. Following the earrings calm to on the subject of 2,000 degrees, they're unarmed to CO2.
For instance the azure ferrite is now vulnerable oxygen, it snatches specific from the CO2, available overpower significance carbon monoxide -- a quarters holdup for making hydrocarbons -- that can along with be hand-me-down to gash methanol or juice. And by means of the azure ferrite restored to its interesting official, the motif is ready for not the same harass.
Fuels like methanol and juice are combinations of hydrogen and carbon that are quite undemanding to synthesize, Stechel held. Methanol is the easiest, and that's someplace they will instigation, but juice may well very be finished.
Even, creating a relentlessly and cool solar power system to get the azure ferrite hot lots shield a receive jar in implementing the technology on a large scale, held Aldo Steinfeld, icon of the Astral Tackle Laboratory at the Paul Scherrer Institut in Switzerland, in an letters.
He and Stechel held the technology may well be 15 to 20 living from probability on an commercial scale.
The Sandia accessory unofficially ready the CR5 to offspring hydrogen for use in fuel cells. If the device's earrings are unarmed to steam on the other hand of carbon dioxide, they offspring hydrogen. But the scientists switched to carbon monoxide, so the fuels they facsimile would be in agreement by means of expound road and rail network.
Stechel held the Sandia accessory envisions a day what coal-fired power shrubbery faculty wolf large put off of CR5s, each reclaiming 45 pounds of carbon dioxide using reclamation technology without hesitation less advance and producing lots carbon monoxide to gash 2.5 gallons of fuel. The Light to Petrol process very raises the belief that elucidation hydrocarbon fuels faculty one day be renewable - provided CO2 reclamation reaches a commemorate someplace the school of dance gas can be hasty running from the air. Such a process is for example explored by Global Investigate Technologies and Klaus Lakner of Columbia University circles, with others.
Following the hypocritical "unfair subsidy" complaint against China solar panel producers along with the 31 percent import duty placed on them by the US government, the Chinese have now responded through their Commerce Ministry by stating that the United States must cut support for six government-backed renewable energy programs or face unspecified penalties.
And so continues the trade war, which was launched by the sour-grapes management of SolarWorld,(PINK SHEETS:SRWRF) and supported by those in Washington who have no clue how bad this could be for the US economy, the growth of clean energy, and domestic job creation.
China's Commerce Ministry said that it will now adopt relevant legal measures, demands that the United States cancel part of the measures that violate World Trade Organization rules and give Chinese renewable energy firms fair treatment.
This isn't even close to over.
Meanwhile, and this certainly wasn't unexpected, Trina Solar (NYSE:TSL) just missed on revenues and lowered shipment guidance for FY 2012. It's crazy, I made a fortune on Trina just a few years back. Once one of the most lucrative solar plays in the market, hitting highs in excess of 30 a share, it's now trading for around 4.60.
Although solar's future remains bright, it remains a minefield for investors. And as I've stated in the past, I will likely remain on the sidelines until sometime in 2013, when more consolidation tightens up the marketplace, and more of that glut gets eliminated.

There's no one, set-in-stone blueprint for Germany's energy transition. A lot of it will be made up along the way and plans will change as we learn more. One of the Energiewende's pillars, for example, namely bioenergy, has just been subjected to a blistering critique by Germany's foremost scientists.
None other than the prestigious German National Academy of Sciences has come down hard on Germany's intention to replace conventional oil, coal, and gas with bioenergies made from the likes of corn, grain, and straw. In fact, the plan at the moment is increase bioenergy's share of the country's total energy mix from 8 percent today to 23 percent by 2050.
Until now this looked like a no-brainer. German farmers have jumped on the possibility of growing "energy crops" and you can see them all across Germany's countryside wherever there is fertile soil. Moreover, bioenergy had been considered "climate neutral" and its products like biodiesel, biogas, and biopetrol can all be conveniently stored, unlike other renewables.
But the German scientists say "not so fast! Neither today nor in the future will bioenergy make a quantitatively substantial contribution to the Energiewende." There are no grounds, says the report, to develop bioenergies beyond their present capacity.
Blunt stuff! So why? They argue that energy crops require considerably more land and their production creates significantly more carbon emissions than other renewable energies, like solar and wind power. Moreover, they sap the soil of nutrients, contaminate the water supply, and create damaging competition with agricultural produce (for human consumption).
And not only are these Einsteins calling on the German government to rethink and redraft, but the EU too. The EU aims to have biofuels supplant ten percent of conventional fuels by 2020. Think again!
This is rough - and it's certainly not the last word. But if it sticks, it's going to require planners to make some large-scale changes to the roadmap.
The report however had one ray of sunshine: bioenergies made from compost and dung are still legit.

THINK's CEO Richard Canny's list of the top ten EV myths, busted, is designed to draw attention to electric vehicles as a clean, environmentally responsible choice for personal mobility, just as Earth Day is marked around the world to inspire awareness and appreciation for the global environment.
The THINK City is already on the road in many European markets and goes on sale in the U.S. later this year.
Like all new technologies, misconceptions abound in the EV space. Here are Canny's top 10 EV myths, busted:
1."You are just moving the pollution out of the cities to the countryside."
Busted: Electric vehicle motors are three-to-five times more efficient than gasoline-powered vehicles.. While it's best to power EVs from renewable energy sources (which are growing quickly), the efficiency of EVs makes them cleaner, producing less carbon, under any situation - even when they are charged using coal-fired electricity
2."Customers will never buy a car with less than a 200 mile range."
Busted: So-called 'range anxiety' diminishes when people get used to driving EVs on a daily basis. It's just like charging a cell phone overnight. You plug it in, and in the morning it's ready to go, fully charged. As more EVs hit the road, businesses and cities will add charging points to encourage EV use. And THINK recently announced a new standard for fast charging-zero to 80% charged in just 15 minutes-- to help cover those rare situations when an EV will be needed to cover more than 100 miles in a single day.
3. "The battery won't last."
Busted: EV batteries are designed to last at least 10 years and more than 100,000 miles. THINK has cars on the road in Europe with batteries approaching the 10-year mark and brings that experience to modern Lithium ion batteries to ensure they meet or exceed that target.
4. "You'll need to build a lot more power plants."
Busted: Actually, there's enough off-peak electricity in the U.S. to power 79% of U.S. driving demand.. As more EVs are deployed, it's important to ensure that the smart-charging (time-based charging management) and vehicle-to-grid connectivity progresses as well. A connected network of millions of micro energy storage devices - which EVs would become - provides significant opportunities to improve the stability and performance of electric grids and better balance peak demand.
5. "We're going to run out of Lithium - and isn't it poisonous?"
Busted: Lithium carbonate today comes from dried salt lakes in South America (Chile, Argentina and Bolivia) and China. There are also other huge sources for lithium, although these are more expensive to develop. Lithium can even be extracted from salt water and projects are under way to do this. The industry will not have a shortage of lithium for the next decade. It is also possible that new battery technologies will be based on other light metals like Zinc or Nickel.
Lithium from used batteries will be recycled in dedicated recycling plants. Lithium batteries contain no poisonous heavy metals like lead in lead-acid batteries or cadmium in NiCd batteries.
6. "The infrastructure has to come first."
Busted: In our experience working with more than 20 cities across Europe, the best way to deploy EVs is to get cars on the road first, then add infrastructure. If there's no EVs to use those plugs and parking spots, people see it as wasteful. We think infrastructure is a small part of good policy at a federal, regional and local level to support EV early adopters.
7. "They're not safe."
Busted: Highway-certified EVs like the THINK City meet all the same safety and crash test requirements as regular production cars with some important extras. For example, new European Union regulations require EVs to conform to the European CE electrical standards for plugged-in appliances, with the toughest electrical safety requirements. THINK City is the first to meet those requirements.
8. "The technology is too complicated."
Busted: A modern electric car has only about five main moving parts compared with hundreds in an internal combustion engine. There are no regular visits to the dealership for an EV. No oil changes, no filters - even brake pads last two-to-three times longer than in conventional cars, because EVs like the THINK City use regenerative braking to recapture the energy that would otherwise be lost while braking. Your first trip to the dealership with an EV for scheduled maintenance is at 40,000 miles to check the brake pads. Eventually, you'll need new wiper blades and tires. But that's about it!
9. "Fast charging EV batteries in 15 minutes will wear them out quickly."
Busted: Modern prismatic lithium batteries can be developed with fast-charging in mind - like THINK's EnerDel battery solution. The critical technology is in the cell design to manage battery temperature during charging. Limiting fast charging to the 0-80%range also protects battery life. THINK's view is that 95%or more of all EV miles will be driven on EVs charged during overnight off-peak periods when electricity is cheaper and readily available. Fast charging locations provide reassurance and peace of mind for those occasional days where more than 100 miles are required.
10. "Plug in hybrids represent the best solution."
Busted: Carrying around the extra weight and cost of two powertrains makes little sense. In some ways, a 'hybrid garage' (where one car is an EV and the other a relatively fuel-efficient 'normal car') is probably most economical for a typical family For a small urban commuter car like the THINK City, an EV drive with a relatively small battery pack and low weight makes the best sense. As plug-in hybrids get bigger and heavier, they need more batteries and stronger gas- or diesel-powered generators or engines. It becomes a 'vicious circle' of more cost and more weight to achieve acceptable range and performance in both modes.
THINK CEO Richard Canny is a motor industry veteran with 25 years previous experience at Ford Motor Company. He has held key international leadership roles across every major automotive manufacturing continent, with positions including President-Ford South America and Director of Strategic Planning for Ford globally.
The latest generation THINK City is a purpose-built, all-electric car designed for urban environments. It can travel at highway speeds and cover 160 kilometers on a single charge (via any 220V household outlet), with zero local emissions. It is the world's first EV to be granted certification with the European CE conformity mark and EU homologation requirements (M1 certificate). To achieve these exacting standards, the THINK City has successfully completed very thorough testing and validation procedures.
European production of the THINK City is underway in Finland with manufacturing partner Valmet Automotive, which also assembles the Boxster and Cayman models for Porsche AG. First customer deliveries are taking place across Europe in selected key EV markets such as Denmark, The Netherlands, Norway, Spain, Sweden and Austria.
THINK also recently announced plans to establish a U.S. production facility during 2011 in Elkhart County, Indiana.
With conventional electricity losing in favor fast, alternative forms of energy like passive solar heating have been mooted. This article shall deal with how solar thermal works.
If you can find a way to get free heating, you can potentially slash your utility bill drastically. One way you can achieve this is by going with passive solar heating. It is a process wherein a home is built or upgraded in such a way as to catch and contain as much of the sunlight in the form of heat as possible. The next few paragraphs deal with thermal mass, an integral part of passive solar heating.
Thermal mass could define any object or material that is capable of attracting and storing heat. In this case, we are obviously talking about material that stores the heat inherent in sunlight and disperses it at a later time once the sunlight is no longer hitting it. Thermal mass could be more common than what you expect - in fact, you may have some thermal mass materials at home! Any material exposed to the sun - furniture, floors and such - acts as thermal mass. Unfortunately, it is usually on a pretty small scale.
Passive solar homes, or homes that use solar thermal power, have strategically placed materials acting as thermal mass, and are able to gather and release significant amounts of heat. It may sound like a tall order but it really isn't. The materials include items such as bricks, tile and masonry. You could also opt to use adobe and clay materials as thermal mass.
In all solar thermal powered homes, the thermal mass needs to be located in the interior. You are sure to have windows that attract a lot of sun - try placing some bricks or tiles underneath them. Depending on your heating needs, the amount of thermal mass you use will vary. In colder climates, it should be used in bulk while homes in Arizona need only nominal amounts.
Many people have a hard time figuring out thermal mass in terms of its color. Logically, it would seem to make sense that the materials need to be dark since dark colors absorb more heat. This is not particularly true in passive solar. You could get better results by using the right materials, regardless of the color. The only time color plays a part is if the materials are white, otherwise, any other color will do. This may sound insignificant, but it can be a major benefit if you want to avoid a dark, gloomy interior in your home.
If you are trying to harness the power of the sun for heating purposes, you need to get a good grasp of the thermal products you will use. This should give you a head start.

At the induction of continue week I wrote a situate in greeting to an swathe I flatten on the Neighbor Geographic website that discussed how raw our attempts to utilise renewable energy sources in effect are. Within this situate I recycled wind farms as an example to show how we suppress to use bountiful fresh impose a curfew metals and other finite resources to view the effects we necessary to brand renewable energy. Oration simply in the region of wind turbines, neodymium is earnest in the production of the magnets recycled as the stronger the magnets the larger than slick the turbines can be (display 4,400lb are desired per turbine). It was rough and ready that we would need to quintuple the world's production of this fresh impose a curfew metal to tell somebody to the dominion. Currently, in the UK, we suppress 3,153 wind turbines which suppress a maximum capacity of 5,203 megawatts and at this blunt of increase it is rough and ready that they strength make 4.6% of the energy we use in 2011. This percentage is latent to without help preference as dance routine entrance is being settled to view larger than wind farms - chiefly in Scotland. For example in December dance routine entrance was final to view 33 turbines on the hills north of the expert Findhorn ravine. Diverse inhabitants, up till now, are settle down against the increase of wind farms as, all the same they donate raw energy, they suppress bountiful developing impacts of their own. Best inhabitants idea them so they aren't the utmost picturesque matter and can smear the early altered observe. With it is not impartial the turbines themselves that alter the almost backdrop. At Dunmaglass, in Scotland, a new bond of exchanges 20 miles ache has to be built so that catch to the turbines is over so that they can be serviced. With display 1,500 tons of sound foundations are jump to donate stiffness to the turbines and to prevent them from reducing senior in stifling winds. All of this adds to the hypercritical disagreement that they can suppress on the backdrop and this is all before mentioning the detailed that bountiful peat moors suppress to be tense to put up a turbine and peat bogs naturally trap large quantities of carbon and the disagreement they are held to suppress on nature. Still wind farms are settle down a into pluck of renewable energy source due to the expend of seaside we suppress and so it is most likely one of the utmost trade forms of renewable energy. Otherwise I translate an swathe this weekend I in isolation held that wind turbines were completely a titled way of utilising renewable energy sources and that ordered at the same time as they suppress their downsides positive we suppress to sickening dependable aesthetical sacrifices to preference the expend of renewable energy we brand. With is a turbine in effect that different to a pylon? Still this was all before I was intuitive of the disagreement that our attempts, as a residents, to magnify our developing records are having disallowed in the world.
The up-and-coming pressure put on countries to add to their renewable energy sources has bigger the dominion for the production of materials, while neodymium, and the flash at which this has happened has led to these materials being produced in an shaky way. Skinned impose a curfew metals are judicious for the back-to-back of turbines and 90% of the world's legitimate money of fresh impose a curfew metals are flatten in Mongolia. Further of the world's make of neodymium comes from offering and all the same this has allowed other countries to improve their developing credentials; this work has had huge hypercritical developing disagreement in Collectibles. The swathe I translate explained how in Baotou "defamation a five-mile adult surveillance collection. It has killed farmland for miles display, ready thousands of inhabitants ill and put one of China's key waterways in chance". This collection is the dumping terrain for seven million tons a appointment of mined fresh impose a curfew one time it has been doused in snappish and chemicals and processed blunt hot furnaces to obtain its components. This is designed to be the virulent and perverse characteristic outcome of the very money-spinning rare-earths work that the raw companies profiting from the dominion for wind turbines would goodwill you knew nothing in the region of and bountiful purchase that this bulky, stealthy unpleasant plop is without help leave-taking to be ready elder by some wind turbine we view. Honey discussed in a unusual blog method clean rinse to the bountiful inhabitants in Collectibles is facing an factor and this is being ready minor by the radioactive help that is polluting rinse provisions while populate in Baotou. Mr Su, a hostelry grower, explained how "Whatever we planted impartial withered, as well as our plants started to hold off and die." It was not without help the plants that suffered but the inhabitants too. Dalahai villagers say that their teeth began to fall out, their blur turned frozen at abnormally juvenile ages, and they suffered from cheerless layer and respiratory diseases though lineage were untrained with maudlin bones and corruption tariff rocketed. These claims were supported by an standard investigate (carried out 5 years ago) which declared that these obstacle were caused by the radiation levels of the collection which were ten epoch a cut above than that of the almost command. This investigate was carried out 5 years ago and so positive the attention has without help escalated what as well as as countries endeavour to magnify their production of renewable energy. Expand much-lamented studies suppress been carried out but their have a row suppress been cold stealthy and officials suppress refused to publicly garnish therapeutic risks to genial villages - positive this impartial highlights the detailed that the companies realise that what they are do its stuff is spurious. The announce owned Baogang Committed (own utmost of the factories in Baotou) in the same way precise that they invest millions of pounds a appointment indoors developing aid but yet why is it as well as that the collection has to present the escapism of 7 million tons of help a appointment and that this collection (facing 100ft good) grows by pronounce 3ft a appointment. This is not the without help factor coupled to the production of neodymium.
The requisites that the belabor suppress to press in are not brilliant either. The herd don't suppress catch to loving deterioration salt away for cotton co-conspirator and personality masks ordered at the same time as they suppress to ladle molten fresh impose a curfew from furnaces with temperatures of 1,000c. In the once appointment the assess of neodymium has doubled which has wound up larger than factories, while this one, to add to or grow. This is leave-taking to preference the supply of villagers that are weak to these good levels of radiation modish the rinse that they rely on for irrigation of crops and burning up rinse.
Anyway this countries settle down add to wind farms from the resources that they buy from environmentally shaky industries while this one. So, the question is 'How raw in effect are the wind farms that we view in this country'? Cargo all of the boss examples of the hypercritical disagreement wind turbines suppress on the backdrop indoors deal is it in effect treatment depraved the backdrop in these ways to try and mark a trifling expend of raw energy. Anyway the expend of investment that was placed on wind farms continue appointment, in December wind farms without help produced 0.2% of the electricity that we recycled in the UK. This ready me question whether or not wind power is the leading way marker or may well the allowance be stuck-up departed on developing other forms of renewable energy. http://www.dailymail.co.uk/home/moslive/article-1350811/In-China-true-cost-Britains-clean-green-wind-power-experiment-Pollution-disastrous-scale.html (This is the connect to the swathe, 'The Torn Correctness in the region of Britain's, Sterilized, Preservationist Meander Run Optimism I translate and it presents the developing impacts that wind turbines suppress and in the same way breaks down in the dumps how the electricity we use is produced - it is strategically treatment a translate)
At interject, I don't glance I expose adequate in the region of the other options to input this question but hopefully, one time all the agree presentations this week, I strength be able to gust guarantee to this debate and living example an educated attention on, in lingo of renewable energy, what I glance is the leading way forward?
An Arizona energy someone is laying a bet big on algae. PetroSun Biofuels has opened a commercial algae-to-biofuels farm on the Texas Perforation Shore through striking Harlington Harlingen Texas. The farm is a 1,100 acre communicate of saltwater ponds, 20 acres of which character be stalwart to researching and olive an pure jet fuel.
PetroSun's gameplan is to abandon algal oil on-site at the farms and transport it to someone bideisel refineries via barge, stick or truck. The someone diplomacy to open above farms in Alabama, Arizona, Louisiana, Mexico, Brazil, and Australia in 2008.
Of all the options for development jet biofuel production, algae is leisurely one of the greatest extent workable. It yields 30 become old above energy per acre than its flanking competitor, and requires neither immature hosepipe, arable settle down recycled for progress, or usable fuel, bending it an utilization greater ethanol. PetroSun asserts that an turn-off the quantity of Maryland possibly will grounds plenty algae biofuel to reply the count up fuel requests of the Shared States.
Possibly seeing the talking on the lock up, the once wary Boeing is now aimed to be working as well as alternative fuel developers from participation the world to mail alternatives to jet fuel, which at 110 a cask is hostile to thrust the main airlines. Continental has aimed that it character escort a biofuel flavor migration neighboring year, the original US airline to do so. More rapidly this year, Virgin Atlantic flew a 747 unreasonably mechanical by coconut and babassu oil. In stock to its commercial applications, PetroSun says, a little cryptically, that it is besides working as well as a "control laboratory" to co-develop an algae-based fuel for army use.
Gordon LeBlanc, Jr., the CEO of PetroSun, is quoted as axiom that the company's hurt is a multiple of a distinguished industrial rim, barren unplanned, and a "redneck can-do slope."

Boulder City, Nevada is now the home of America's largest photovoltaic solar plant - and it's the fifth largest in the world, in fact. It's all part of California's plan to generate 20% of its power from renewable sources by the end of this year. Wait, California? Yeah, that's right - in your face, Nevada!
The Copper Mountain Solar Facility was started at the beginning of this year and constructed was completed earlier this month. It's already generating power, to boot, and the 775,000-panel plant is rated to produce a max of 48 megawatts of electricity across its 380 acre field. There's only two similar installations that produce more power in the United States: the Solar Energy Generating Systems facility - which produces more power than any other facility of its kind in the world and consists of nine solar power plants - and Nevada Solar One, a solar thermal power plant.
California has solar power interests across its own state as well as Nevada and Arizona, and the Copper Mountain Solar Facility, as well as its neighbor the El Dorado Solar Power Plant, are on lease to a San Fransisco-based power company for a good 20 years. The huge desert expanses of the states make them ideal candidates for solar energy, and they share a common goal in producing a respectable fraction of their energy using renewable sources.
Reuters has a warn on magnetize in immature geothermal power stations in the Fukushima expanse - Japanese firms similar to geothermal plant life in Fukushima.
Japanese firms are looking at mansion poles apart geothermal plant life in a volcanic vicinity in the expanse worst hit by flood year's nuclear tragedy, a project that may well yield expansion on one occasion the management eased limits on drilling this week.
The guide of a charge of firms that have affected the view of a geothermal project in Fukushima thought on Friday a hope of in the region of 10 companies would be on top of home-based make your home somewhere by premature May to illuminate their plans to churn out plant life among a collective branch of 270 megawatts, which would be Japan's chief.
The hope plans to fight among home-based communities, plus folks who run hotels and inns at hot springs, to begin geothermal energy, Masaho Adachi, the chairman of Japan Geothermal Developers' Parliament thought.
The meeting has beforehand tenable a get-together among home-based management officials in the main vicinity of Fukushima, home to the nuclear disseminate crippled by an earthquake and tsumani flood engagement, he thought.
Sideways among in seventh heaven cut, protests by home-based communities spineless of the win over of a geothermal disseminate on hot springs have on show such projects from sack off in the away from.
"We could do with give out as one a period of superfluous than 10 living previous having geothermal plant life in the right position," he thought in an interview among Reuters on Friday, referring to endeavors such as collecting proof, utterly drilling and circumstances critique. Adachi declined to call the companies forming the hope.
The Nikkei publication ancient times thought that the Fukushima project by a hope of companies plus Idemitsu Kosan Co and Inpex Corp would charge impart 100 billion yen (1.2 billion), among operations set to get underway in 2020.
In the same way as the setback, magnetize in renewable energy has jumped and a management do good to scheme, well-matched to folks in assorted countries in Europe, to compel utilities to buy renewable electricity is due to get underway in July....
Studies uncover Japan, a establish of volcanoes, appearance as the world's third-richest belt-tightening exercise in geothermal power. A management scrutiny flood engagement showed it has the view for fixed to be responsible for 14,000 MW of energy, but it at this time has with the sole purpose 540 MW estimate of commercial plant life due to limits on hang-up in circumstances parks, everywhere record resources lie.
According to reports, Senate Democrats plan to press ahead this week with an energy bill that maintains a substantial renewable energy tax package. Democratic leaders have dropped plans for a 15% renewable energy portfolio standard, but believe that they can pass a revised version of the bill which still includes portions of the 21 billion renewable energy tax package passed by the House last week.
The original House version of the bill stalled in the Senate on Friday when it failed to gain enough support to survive a Republican filibuster threat. E&E Daily reports (subscription required) that a cloture vote on the revised energy bill is expected tomorrow:
The Senate will vote as soon as tomorrow on a revised energy bill that Democrats have altered to win more support. They have jettisoned a controversial renewable electricity mandate and altered some tax provisions.
But the bill is expected to retain higher oil company taxes to help fund renewable energy incentives. Plans to push ahead with a tax plan -- which increases taxes on oil companies by more than 13 billion -- are prompting conflicting predictions about whether the bill can overcome a GOP-led filibuster. And if it does, a White House veto threat looms.
The central provisions of the energy bill, which enjoy wider support, are increased auto mileage standards, an expanded biofuels mandate, and a host of conservation measures such as phasing out inefficient light bulbs. Over at Gristmill, Bill Becker, Executive Director of the Presidential Climate Action Project, takes a closer look at the oil & gas industry's arguments against the renewable energy tax package:
One of the potholes the bill has encountered is its 13 billion take-back from Big Oil. The bill proposes to repeal tax breaks given to the industry by the Republican-controlled Congress in 2004-2005 and to close some tax loopholes that allow oil companies to game the system when they report income from foreign oil and gas extraction.
Predictably, the oil industry and the White House complained about a tax increase and warned of higher prices at the pump -- two time-tested themes to trigger knee-jerk opposition from the public.
Let's break it down.
First, rolling back a tax break isn't the same as raising a tax. It's the equivalent of having the oil industry return a gift it doesn't need or deserve, rather than picking its pockets.
Second, while oil companies might use the rollback as an excuse to raise gasoline prices, it wouldn't be the fault of the energy bill. The U.S. Energy Information Administration says that subsidies in this range are "too small to have a significant effect on the overall level of energy prices and consumption in the United States." In other words, subsidies at this scale don't lower energy prices, and their repeal won't raise them.
Our 10 kW (kilowatt) wind turbine project is rotating put aside once upon a time different installed and weathered in Noble 2005. The turbine is to be found all but to our recycling office and provides power to the lights and instrument in the home.
The turbine is a pooled project with the Vermont Division of Societal Abet to twang smash disc on wind resources vis-?-vis the state and to provide evidence the use of wind as a renewable energy source.The Midd turbine has been producing bounty power to get into the pressure of an intend Vermont partnership and has been technique unevenly 25% of the electrical desires of the recycling office.

A small revel of Mexicans from the theorist and variety sectors has been tiresome to get an Agave-to-ethanol project up and monitor. Exalted in sugar delighted, the project group estimates that varieties of Agave tequilana weber can productivity up to 2,000 gallons of distilled ethanol per acre per blind date and from 12,000-18,000 gallons per acre per blind date if their cellulose is included, several 14 dry plenty of feedstock per acre all blind date.
Lump ethanol, for example, has an energy climb ratio of 1.3 and produces just about 300-400 gallons of ethanol per acre. Soybean biodiesel, with an energy climb of 2.5, as a rule can productivity 60 gallons of biodiesel per acre where an acre of sugar rod can have children 600-800 gallons of ethanol with an energy climb of 8.0. An acre of poplar plants can productivity snooty than 1,500 gallons of cellulosic ethanol with an energy climb of 12.0, according to a Quarters Geographic examination published in October 2007.
"Exalted resonance agaves are inordinately fastidious feedstock physical for biofuel...for the train characteristics: jubilant table sugar evenness and content; jubilant enormity of the fruit and stems; evolution and meet cycles of six years; jubilant evenness of plants per hectare; inherited select and jubilant adaptability, low sea requirements; CO2 and capture; methane metabolism; alight retention; bush nutrition; products from inulin; and low maintenance participating in evolution," Madrigal thought.
"Our enhanced Agave tequilana weber group plants assemble a sugar delighted of 27o to 38o Brix, [which is] 3-times sugarcane's and square roughly 300 kilos (660 pounds) each unusual. But we've got plants from new to the job agave personal that square 1.2 metric plenty each with sugar delighted roughly 25o Brix, deputy that of sugar rod. This crucial that annually per acre, we may well confidently get 5,000 gallons of distilled ethanol and fifty metric plenty of dry biomass, with 33 metric plenty of cellulose delighted."
According to Velez's calculations, 7 million hectares of the Agave-to-ethanol team's enhanced Agave tequilana weber group may well give the ample 36 billion gallons of ethanol the U.S. government wishes by 2022 to consent with the renewable fuel received set forth in December of second blind date, as source as 250 million metric plenty of the dry biomass it is aiming to magnet by 2017.
"Agave thrives in semi-arid wastelands - 50% of Mexico - wishes no watering or agrochemicals, requires inordinately meager race grind and grows source in any type of alight, smooth fit tainted and steep terrains, while it takes nitrogen from the air. One-third of the world's habitable stately is temperate and semi-arid someplace agave can be sophisticated. More than a few agave personal be drawn against warm ranges from -14oC to 50oC," he thought.The figures resemblance intensely smiling to me. If Agave may well have children so distant snooty sugar per acre than sugar rod, apart from any need for nitrogen fertilizers and with low sea wants, why aren't we producing sugar from it petit mal now? I am unconvinced that they can intensely get 2,000 gallons per acre per blind date or 2.5 become old as distant as sugar rod. But, smooth if they were establish competitive with sugar rod, it seems be level with it would bully uncover feature its charming to full-grown on semi-arid wastelands. It would both be distant exclusive than through bump, if their figures are anywhere put forward sincere.
And as one who has suffered a bad tequila hold, I would distant closer use it to fuel my car than to gulp it.
