Question

Identify environment-friendly energy resources.

Answer 1

Environment-friendly energy resources are:

1. Solar energy: obtained from sunlight and produces very little pollution during use.
2. Wind energy: generated from wind without burning fuel.
3. Hydroelectric energy: produced from flowing water.
4. Biogas – produced from animal dung and organic waste.
5. Tidal and wave energy: obtained from the movement of seawater.
6. Geothermal energy: obtained from heat inside the Earth.

These resources are generally renewable and less polluting, so they should be preferred and used judiciously.
