Types of Renewable Energy

Plants and crops, such as corn, are renewable resources. Humans can replenish crops yearly.

Biomass

While water exists in a limited amount on Earth, it constantly recycles through the water cycle.

Hydropower

Earth's interior heat provides a renewable energy source. This heat is estimated to last for billions of years.

Geothermal

The wind is the air movement from one place on Earth to another. This movement provides a renewable source of energy.

Wind Power

The energy from the sun is a renewable resource. The radiation from the sun is essential for providing energy for many other renewable resources.

​​Solar Power

A sustainable resource is a resource that meets present needs without limiting future use. Even though many resources are renewable and replenished quickly, overuse of these resources leads to a potential lack of those resources in the future.

​

Sustainable Resources

• replenished quickly enough for consistent use

• found in quantities that are so great, it will not run out for the foreseeable future

Renewable

• not overusing the resource

• taking care of the resource by limiting pollution
