Front

What is the environmental impact of burning non-renewable energy sources?

Back

Burning non-renewable energy sources is harmful to the environment as it releases pollutants and greenhouse gases.

Front

What are renewable energy sources?

Back

Renewable energy sources are energy sources that can be replenished naturally, such as solar, wind, and hydro energy.

Front

What is an example of a non-renewable energy source?

Back

An example of a non-renewable energy source is natural gas.

Front

What is wind energy?

Back

Wind energy is energy generated from the movement of air, and it is considered a renewable energy source.

Front

What does it mean for an energy source to be limited?

Back

An energy source is considered limited if it is finite and will eventually run out, like non-renewable energy sources.

Front

How does coal impact the environment?

Back

Coal impacts the environment negatively by releasing carbon dioxide and other pollutants when burned.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally, while non-renewable energy sources cannot be replaced once used.
