Here's more authoritative documentation:
"China has climbed to its highest ever score in the All renewables index, reaching the level the US held in Q3 2007. This is principally due to China diversifying its renewables portfolio through an increased focus on offshore wind and CSP. This broadening scope as new technologies become commercially viable illustrates a key trend. Examples featured in this issue include offshore wind in Taiwan, UK and the Nordics, with CSP in Morocco, US and India.
The US remains in second position. Although President Obama has voiced his support for renewable energy, significant Republican opposition in Congress is causing a stalemate. Utility scale solar projects currently appear to be immune to this uncertainty, but lack of liquidity in power offtake arrangements remain the major barrier to new utility scale wind projects, particularly in light of the continued suppression of gas prices in the US."
