[1][2] This analysis updates and expands Deploying Renewables: Principles for Effective Policies, published by the IEA in 2008, in light of events and trends in the last five years.

Growth rates are in line with those required for a sustainable energy future: • "The RE electricity sector, for example, has grown by 17.8% over the last five years (2005-09) and currently provides 19.3% of total power generation in the world."

• "The other newer RE electricity technologies have also grown rapidly, by an impressive 73.6% between 2005 and 2009, a compound average growth rate (CAGR) of 14.8%.

Solar PV has grown at a growth rate of 50.2% (CAGR), and installed capacity reached about 40 GW by the end of 2010."

The OECD was the only region where the deployment of less mature technologies (such as solar PV, offshore wind) reached a significant scale, with capacities in the order of GWs."
