According to the Energy Information Administration data, 13.4% of the nation's electricity power from January to March 2011 came from renewable resources. That represents a major increase in market share for renewable energy.
The big jumps came from large increases in hydro production due to record rain fall and another 20% jump in wind power in March 2011 compared to March 2010.
The hydro increases may not be sustainable, but the wind power increased production results from the increasing numbers of wind farms being built around the nation.
Hydro represented 8.2% of electricity produced and non-hydro renewables 5.2%.
