In March and April, the United States produced more of its energy from renewable sources than nuclear, the Energy and Information Administration (EIA) confirmed Thursday.
The US accounts for around 18 percent of the world's total primary energy consumption.
Just over 60 percent of renewable power came from wind and solar, which can often lead to unpredictability based on the weather.
But nuclear production still remains the dominant energy force and experts predict production from nuclear plants will outpace renewables for the coming year.
Nuclear power in the US is provided by 100 commercial reactors with a net summer capacity of 100,350 megawatts (MW) and accounts for about 19.50 percent of the nation's total electric energy generation.
Renewable energy accounted for 14.94 percent of domestically produced electricity in 2016 and 11.1 percent of total energy generation. Hydroelectric power is the largest producer of renewable power in the US, producing around 6.5 percent of the nation's total electricity in 2016 and 45.71 percent of the total renewable power in the US.
The US is the fourth largest producer of hydroelectricity in the world after China, Canada and Brazil.
