Hydropower was king of 'green' energy, but not anymore

Conventional hydropower, which by itself has accounted for most of the renewable energy generated in the United States for years, is no longer a majority of one, according to a report from Breaking Energy.

Other "green" energy sources—including biomass, geothermal, wind and solar—accounted for a combined 281,060 gigawatt hours of net power generation in 2014, together topping hydropower, which generated 258,749 GWh.

The change came about not because hydropower dropped off, but because the other sources are taking on greater prominence. Wind power, in particular, accounted for an increase among other renewables, rising to become the source of 4.4 percent of the nation's total electricity in 2014, up from 4.1 percent the year prior.
