Question 2(a)

State briefly how the Sun's energy can be used to generate power.

Answer

Sun's energy can be transformed into electrical energy with the help of solar cells. Solar cells are also known as photovoltaic cells. They are made up of thin wafers of semi conductor materials from silicon and gallium. When Sun's light falls on them, the Sun's energy gets converted into electricity.
