For the first time, non-hydropower renewable energy sources created more energy in a month than hydro sources. The milestone is a culmination of a decade of growth in wind, biomass, geothermal, and solar power.
But even with the increased productivity of renewable sources, they still make up a small slice of the country’s energy production: 6 percent from hydropower and 7 percent from other renewable sources. Coal is still the biggest producer, and natural gas use is expanding quickly.
Despite major gains in renewable energy production in recent years, the shift away from non-renewable sources will take time. Read more about the changing electric grid here.
