Key facts
Investments
 2012 second highest year in renewable power
investments, ahead of fossil fuels for third year
 $244bn global investments, with continued shift
from developed to developing economies:
Developed markets down 29% YoY due to policy
uncertainties, developing markets up 34% YoY
Drivers
 Climate change: Low-carbon generation
 Security of supply: Fuel independence
