The global clean-energy picture for 2013 was a classic good news-bad news story, according to the Clean Energy Trends 2014 report issued today by clean-tech research and advisory firm Clean Edge, Inc. The industry saw dazzling growth, success, and rising stock prices in some sectors – most notably solar photovoltaic (PV) deployment – but downward trends and policy and finance hurdles in others. 

Last year also marked a significant transition in the history of clean energy: for the first time since Clean Edge began tracking global markets in 2000, the world installed more new solar PV generating capacity, 36.5 gigawatts, than wind power (35.5 GW). Record levels of new solar deployment in China, Japan, and the U.S. combined with a down year in the wind industry to create this unprecedented crossover. 

The global solar market's continued double-digit growth of 15 percent, plus a modest uptick in biofuels' market size, was not enough to overcome the wind industry's lackluster performance. As a result, combined global revenue for solar PV, wind power, and biofuels held nearly steady at $247.6 billion, down just slightly from $248.7 billion in 2012.
