source of energy that is virtually inexhaustible and is naturally and quickly replenished; examples: solar, wind, hydropower (water), geothermal, and biomass
Solar, wind, or bio can all be an acceptable renewable energy resource.
A source of electricity generated from solar, wind, biomass, small hydroelectric facilities, and other resources that can be naturally replenished.
An energy resource that can be replaced as it is used. Renewable energy resources include solar, wind, geothermal, hydro and biomass. Municipal solid waste (MSW) is also considered to be a renewable energy resource.
Energy resource that can be quickly replenished. Certain renewable resources will always be available no matter how they are used (e.g., solar energy), while other renewable resources can be depleted when their rate of use exceeds their rate of replacement (e.g., wood).
An energy resource that is regenerative or virtually inexhaustible. Typical examples are wind, solar, geothermal, and water power.
