• The International Energy Agency predicts that renewables-generated electricity will increase by more than 40% over the next five years.
• The IEA's new report, "Medium-Term Renewable Energy Market Report 2012," anticipates 2011’s internationally total of 4,540 terawatt-hours produced by renewable energy increasing to 6,400 terawatt-hours by 2017.
• The report covered energy from hydropower, bioenergy, onshore wind, offshore wind, solar photovoltaics, concentrating solar power, geothermal and ocean power, as well as solar water heating.

From the article:

The International Energy Agency (IEA), often skeptical about renewables in favor of fossil fuels, has just predicted a 40-plus percent increase in the world’s renewables-generated electricity over the next five years. The figure will go from 2011’s 4,540 terawatt-hours -- a rate that is itself 5.8 percent more than in 2010 -- to almost 6,400 terawatt-hours, a 5.8 percent annual growth rate over the five-year period.

“From 2011 to 2017 renewable electricity generation should expand,” the IEA’s just-released Medium-Term Renewable Energy Market Report 2012 reported, “by 1,840 terawatt-hours, almost 60 percent higher than the 1,160 terawatt-hours growth registered over the 2005-11 period.” ...
