The document discusses bioenergy, which is a renewable energy source made from biomass or organic materials like plants and animals. It can be used to generate electricity by burning biomass to create steam that spins turbines, or to make liquid fuels like ethanol. Bioenergy is considered renewable because biomass sources like plants and trees can regrow. While bioenergy has benefits over fossil fuels, its large-scale production requires a significant amount of land.
