The latest Energy Infrastructure Update released yesterday by the Office of Energy Projects at the Federal Energy Regulatory Commission reports that the US had 1,231 megawatts (MW) of new in-service generating capacity come online in January of 2013 — all of it from renewable sources including wind, solar and biomass. The new capacity for January represents a three-fold increase from the 431 MW of new renewable generating capacity that came online in January of 2012.
Wind energy led the pack with six new units providing 958 MW, followed by 16 new solar units generating 267 MW of electricity and six new biomass units for 6 MW of new generation. Nuclear, hydro and all fossil fuel sources, including coal, oil, and natural gas offered no new electrical generating capacity last month.
Most generating capacity still comes from coal and natural gas, contributing 29.04 percent and 42.37 percent respectively. Generation from oil contributes only 3.54 percent and nuclear provides 9.23 percent of total capacity in the US.
