Question

Describe any four renewable sources of energy.

Answer 1

The following are the renewable sources of energies.
a. Solar energy: Sun is the ultimate source of energy. The heat from the sun is absorbed with the help of solar panels and solar cells and converted into heat, light and electrical energies.
b.Nuclear energy: This energy is produced by the splitting and fusing of the nuclei of atoms. Nuclear power plants release huge amounts of heat energy through this process which is used to produce steam for driving generators.
c. Hydroelectric energy: This energy is produced from water bodies such as rivers. The dams built across them help in generating electricity by passing the running water through turbine generators.
d.Wind energy: Wind turbines are used to generate electricity from strong winds. Wind energy produced from the wind turbines can drive generators.
