Definition

Renewable energy sources are those that can be replenished naturally over short periods of time. They include solar, wind, hydroelectric, geothermal, and biomass.

5 Must Know Facts For Your Next Test

1. Renewable energy sources are considered sustainable as they do not deplete over time.
2. Potential energy in renewable systems often comes from natural processes like sunlight or water flow.
3. Converting renewable energy into usable forms involves processes that preserve the conservation of energy principle.
4. Wind turbines convert kinetic energy from wind into electrical energy without using fuel.
5. Hydroelectric power plants utilize gravitational potential energy stored in water at height.
