Front

What is alternative energy?

Back

Alternative energy is energy generated by natural resources that are renewable, such as wind, solar, and biomass.

Front

Which energy source has the lowest negative environmental impacts?

Back

Solar energy has the lowest negative environmental impacts compared to other energy sources.

Front

What is biomass?

Back

Biomass is energy derived from organic materials, such as plants and plant parts.

Front

What is wind energy?

Back

Wind energy is energy obtained from the movement of air, which can be converted into electricity using wind turbines.

Front

What is nuclear energy?

Back

Nuclear energy is energy released during nuclear reactions, such as fission, and is used to generate electricity.

Front

What are renewable energy sources?

Back

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