Worldwide clean energy spending grew 6.5% in 2011 to $263 billion. Lower clean energy technology prices and increased spending helped the total installed clean energy capacity grow 17.3% to 565 GW. The Group of Twenty (G-20) countries made up 95% of total clean energy spending. China’s investment in clean energy technology grew just 1.1% but was still the most of any country at $45.5 billion. The US, where investment grew 42.4% to $48.1 billion, was the second-biggest spender, followed by Germany, where spending fell 4.7% to $20.6 billion. The largest spending increases were in Indonesia, where investment in clean energy soared 521% to surpass $1 billion, and in India, where spending jumped 54% to $10.2 billion. Venture capital and private equity spending grew 8.6% in 2011 to $8.6 billion, led by the US with $6 billion in spending. Public and private R&D spending fell 18% to $26 billion. The US accounted for 30% of corporate R&D spending and 31% of government R&D spending. Solar energy made up more than half of clean energy technology spending, largely due to the lower cost of photovoltaic modules. G-20 investments in solar energy grew 44% to $128 billion, led by the US, which spent $30 billion. Source: Pew Charitable Trusts
