Identify 3 types of both energy categories and what they are most often used to power

Thermal power, Wind power, Solar energy and Nuclear power are most often used to generate the power around the world.

Explanation:

Thermal power produced by the burning of coal. There are few high grade coal regions around the world, remaining are low grade category and low calorific value. Thermal power station pollutes the environment heavily and coal reserves are gradually decreasing in trend. So more countries lead to the renewable energy such as Solar and Wind energy. These energy are unlimited and eco friendly. Another hand, Nuclear power are generated using Uranium and Thorium, but wastage from Nuclear reactors tends to be highly radiative and affect the land and sea ecosystem.
