Answer: (a) Sun can be taken as an inexhaustible source of energy
Fossil fuel is an exhaustible source. Hydro and wind energy plants can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area. Disposing of waste from a nuclear power plant is the major issue faced by a nuclear plant.
Any sources which will never run out of energy will be categorised as inexhaustible energy sources. We have a lot of these inexhaustible sources depending on the location of harnessing.
- Anything close to the seacoast will have plenty of wind energy as well as tidal energy which are again considered to be inexhaustible
- Harnessing sunlight is better at the desert as well as semi-desert areas where the light energy from the sun could be harnessed throughout the year.
