The United States attracted 48 billion in clean energy investment, a 42 percent increase over 2010. This helped propel the addition of 6.7 gigawatts (GW) of wind and, for the first time, more than 1 GW of solar energy, enough to power 800,000 homes. Total U.S. installed renewable energy capacity at the end of 2011 was 93 GW, second to China. However, America will be hard-pressed to sustain last year's success in the wake of now-expired Treasury grants and the Department of Energy's loan guarantee programs. Also, the production tax credit concludes at the end of this year.
"In 2011, the global clean energy sector grew again, the U.S. reclaimed its lead as the top destination for private investment, and consumers reaped the rewards of significantly reduced prices for clean energy technologies, such as solar panels, which are now nearly 50 percent cheaper than a year ago," said Phyllis Cuttino, director of Pew's Clean Energy Program. "And yet, the yo-yo effect of U.S. clean energy policy hurts the ability of the United States to consistently compete and turn U.S.-led innovation into manufacturing, deployment, and export opportunities. Creative, stable, and transparent policies remain a critical signal to private investors."
Among members of the G-20, the world's leading economies, the United States continued to be the top destination for venture capital and private equity investments with 6 billion. Despite an overall decline in research and development (R&D), the United States accounted for 30 percent of total corporate R&D and 31 percent of government R&D investments. However, the country trailed in asset finance, small-scale distributed capacity, and a variety of other indicators.
The combination of falling clean energy technology prices and growing investments accelerated installation of clean energy generating capacity by a record 83.5 GW in 2011, bringing the total to 565 GW globally. This was nearly 50 percent more than installed nuclear power capacity worldwide at the end of last year. Experts increasingly agree that solar and wind will become cost-competitive with conventional electric generating capacity this decade and therefore will be preferred investments in emerging economies.
G-20 investments in solar continued to rise in 2011, increasing 44 percent to 128 billion. Solar was the leading technology for clean energy investment for a second year. The gains offset a 15 percent decline in investments for both wind and energy efficiency in 2011, compared with the previous year. The cost of solar modules slipped by almost 50 percent in 2011. The United States was the leading destination for solar investments.
"The clean energy sector received its trillionth dollar of private investment just before the end of 2011, demonstrating significant growth over the past eight years," said Michael Liebreich, CEO of Bloomberg New Energy Finance, Pew's research partner. "Solar installations drove most of the activity last year as the falling price of photovoltaic modules, now 75 percent lower than three years ago, more than compensated for weakening clean energy support mechanisms in a number of parts of the world."
China attracted 45.5 billion in clean energy investment, which spurred deployment of 20 GW of wind power, the most of any nation. Germany ranked third for the second year in a row among the G-20 members, with 30.6 billion and 7.4 GW of solar power installed. Italy attracted 28 billion and deployed a world record of nearly 8 GW of solar power. India drew more than 10 billion and had the world's second-highest annual growth rate for clean energy investment.
