Following one of the worst years in economic history, signs of hope
have begun to emerge for the clean-tech sector, with clean energy
becoming a driving force for global economic recovery from Beijing to
Seoul, and Washington D.C. to Brussels. In 2009, combined global
revenue for the three major clean-energy sectors – solar photovoltaics
(PV), wind power, and biofuels – grew by 11.4 percent over 2008,
reaching $139.1 billion. These three sectors are expected to reach
$325.9 billion by 2019, according to the Clean Energy Trends 2010 report issued today
by Clean Edge Inc., a research and publishing firm devoted to the
clean-tech sector.
