renewable sources
Wind, solar, hydro
Renewable sources are natural resources that replenish themselves over human timescales—sunlight, wind, water, and geothermal heat, as opposed to finite fossil fuels.
The phrase appears most often in energy discussions: The country is investing heavily in renewable sources.
Sometimes shortened to renewables: Renewables now account for thirty percent of the grid.
