Jan-Apr 2015 - US Adds 1,900 Megawatts Capacity; 60% Wind, 20% Solar, 2.4% Geothermal Steam
Renewable energy continues to run the table in the United States. The Federal Energy Regulatory Commissions Office of Energy Projects has released its latest Energy Infrastructure Update, and it shows that all of the new electricity generating capacity brought online during the month of April in the United States was from wind and solar.
That capped off an impressive first third of the year for clean energy growth. Of the 1,900 megawatts of generating capacity added to the USs energy mix in the four months from January to April 2015, more than 60 percent was from wind (1,170 MW), nearly 20 percent was from solar (362 MW), and another 2.4 percent was from geothermal steam (45 MW).
In total, those three clean energy sources geothermal, solar and wind accounted for about 83% of all new generating capacity brought into service in the US so far this year, while no new capacity from biomass, coal, nuclear or oil has been reported.
No new natural gas capacity was reported for the month of April, though a little over 300 MW of new capacity has been brought online so far year-to-date down from over 1,500 MW in the same time period last year.
