Back

Renewable energy is energy that is collected from resources that are naturally replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Front

Why is solar energy considered renewable?

Back

Solar energy is considered renewable because the sun's energy will not run out for billions of years.

Front

What is hydro power?

Back

Hydro power is a renewable energy resource that uses the energy of flowing water to generate electricity.

Front

What is a key benefit of wind power?

Back

A key benefit of wind power is that it is a renewable source of energy that will not run out.

Front

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 the main advantage of geothermal energy?

Back

The main advantage of geothermal energy is that it produces very little air pollution.

Front

What is the role of a dam in a hydropower plant?

Back

The dam in a hydropower plant is primarily responsible for converting the potential energy of stored water into kinetic energy.

Front

What is the difference between renewable and nonrenewable energy?

Back

Renewable energy comes from sources that can be replenished naturally, while nonrenewable energy comes from sources that are finite and will eventually run out.

Front

What are some examples of renewable energy sources?

Back

Examples of renewable energy sources include solar energy, wind energy, hydroelectric energy, geothermal energy, and biomass.

Front

How does solar energy work?

Back

Solar energy works by capturing sunlight using solar panels, which convert it into electricity or heat.
