100% of Power Installations in US Came from Renewables in July21 Aug 2014 |
Renewable energy is dominating new power installations in the United States, with all 100% of July installations coming from renewables.
379 megawatts of wind power were added, 21 megawatts of solar power were added, and 5 megawatts of water power were added. (Note that these numbers don't include small-scale installations such as rooftop solar power systems.)
July was one of the best months for renewables, but it actually fit the trend of the past year or so, with an important difference being that natural gas has led new installtions for the year to date. From January through July of 2014, 2185 MW of natural gas power capacity were added, compared to 1226 MW of solar power capacity, 1196 MW of wind power capacity, 87 MW of biomass power capacity, 32 MW of geothermal power capacity, 19 MW of water power capacity, and 11 MW of oil power capacity. No coal or nuclear power capacity was added.
However, when it comes down to it, US power capacity still largely comes from fossil fuels. 28.45% comes from coal, 41.82% comes from natural gas, 9.24% comes from nuclear, 4.03% comes from oil, 8.57% comes from water, 5.26% comes from wind, 1.37% comes from biomass, 0.33% comes from geothermal, 0.75% comes from solar (again, however, this doesn't include rooftop installations), 0.10% comes from waste heat, and 0.07% comes from "other" sources, whatever they may be.
In other words, we still have a long ways to go to clean up the US electricity supply.
