Global investment in renewable energy sources grew by 32% during 2010 to reach a record level of US$211bn (£132bn), a UN study has reported.
The main growth drivers were backing for wind farms in China and rooftop solar panels in Europe, it said.
It also found that developing nations invested more in green power than rich nations for the first time last year.
The Global Trends in Renewable Energy Investment 2011 report was prepared for the UN by Bloomberg New Energy Finance.
"The continuing growth in this core segment of the green economy is not happening by chance," said Achim Steiner, executive director of the UN Environment Programme.
"The combination of government target-setting, policy support and stimulus funding is underpinning the renewable industry's rise and bringing the much needed transformation of our global energy system within reach."
Seems that solar is getting somewhere: Lower prices/more manufacturing of panels/better quality/catching on.
The government tax deduction etc. % for solar is getting better too here in the US. Thinking fairly soon it will be something I can do. Roomers that solar isn't effective are falling to the wayside as better technology steps in. A Winery just a few miles from my house is completely solar (panels on top of a barn) and actually gets paid for the electricity it does not use from the panels.
Soon, very soon.
