Wind, solar and tidal (or wave) power.
They are considered renewable because no matter how much wind or sunlight or how many waves you use, you’ll never consume it all. Petroleum products like oil and natural gas are not renewable because there is a finite amount of it in the ground. When it’s gone, it’s gone.
It may not be windy, sunny or wavy every day, but there’ll always be more.
