The report, Who's Winning the Clean Energy Race? Growth, Competition, and Opportunity in the World's Largest Economies, also identified the "remarkable growth" in the clean energy sector:
- Since 2005 global clean energy investments have grown by 230 percent
- Over the last five years, clean energy investments have increased by 50 percent by the overwhelming majority of G-20 countries
- In 2009, clean energy investments accounted for more than $160 billion
- In 2010, clean energy investments are expected to reach $200
The report noted that countries with "strong nationwide policy frameworks, including renewable energy standards, carbon markets, priority loans for renewable energy projects and mandated clean energy targets" such as Brazil, China, Germany, Spain, and the UK "have the most robust clean energy sectors as a percentage of their economies." On the other hand, the report said that countries -- such as Australia, Japan, and the U.S. -- that lack such policy frameworks "lag behind."
