(a)
| Renewable sources of energy | Non-renewable sources of energy |
|---|---|
| Renewable sources of energy are the sources of energy that are replenished at a rate faster than the rate at which they are consumed. | Non-renewable sources are the sources of energy that are consumed at a rate faster than the rate at which they are replenished. |
| Renewable sources of energy are known as inexhaustible sources of energy as they can be easily regenerated at a constant rate. | Non-renewable sources of energy are known as exhaustible sources of energy as they get easily exhausted and the resources of this type are limited in nature. |
| Examples; of renewable sources of energy include sunlight, wind, tides, and geothermal energy. | Examples; of non-renewable resources of energy are fossil fuels, which include coal, petroleum, and natural gas. |
(b) Sun and biogas are the renewable sources of energy among coal, biogas, sun and natural gas.
