What are renewable resources?

Back

Renewable resources are natural resources that can be replenished naturally over time, such as solar energy, wind energy, and geothermal energy.

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth, which can be used for heating and electricity generation.

Front

What is solar energy?

Back

Solar energy is energy harnessed from the sun's rays, which can be converted into electricity or heat.

Back

A long-term consequence is an effect that lasts for an extended period, often permanently, such as a nuclear energy accident causing permanent evacuation.

Front

What is an example of a resource that can be both renewable and nonrenewable?
