Global economic turmoil and solar company bankruptcies be damned – economies of scale and falling prices are keeping green energy growing.
That’s according to research firm Clean Edge, which reported Tuesday that global revenue for solar PV, wind power and biofuels rose 31 percent to reach $246 billion in 2011.
Clean Edge put the global solar market at $91.6 billion in 2011, up from $71.2 billion in 2010. That outpaced wind power’s growth to $71.5 billion in 2011, up from $60.5 billion in the previous year.
The global biofuel market grew to $83 billion in 2011, up from $56.4 billion in 2010, though that was largely due to a big increase in biofuel prices, Clean Edge reported.
