Who's winning the clean energy race- G20 Investment powering forward:

This report examines key financial, investment and technological trends related to clean energy in the world's leading economies, also known as the Group of Twenty (G-20). Our primary focus is on investment, which is the fuel that propels the innovation, commercialization, manufacturing and installation of clean energy technologies. The data have been compiled and reviewed by Pew's research partner, Bloomberg New Energy Finance, a market research firm focused on renewable energy.

Our research shows that the clean energy sector around the world has roared back from flat recessionary levels, increasing 30 percent from 2009 to achieve a record $243 billion worth of finance and investment in 2010. More than 90 percent of all clean energy investments were directed to companies and projects in the G-20. Excluding research and development funding, clean energy finance and investment in the G-20 countries totaled $198 billion, 33 percent more than was invested in 2009.

Collectively, the European region was the leading recipient of clean energy finance, attracting a total of $94.4 billion. Europe's leadership position was solidified by more than 100 percent growth in investment in small-scale solar installations in Germany and Italy. Rising among the ranks of top-10 countries for private clean energy investment, Germany and Italy attracted $41.2 billion and $13.9 billion, respectively.
