Question

Write four ways by which we can conserve energy.

Answer 1

Judicious and economic use of energy to lessen the burden on non-renewable sources of energy is called conservation of energy and some of the ways by which we can conserve energy are discussed below:

1. Switching to solar energy: Using devices like solar cookers, solar heaters, solar cells, etc that work on solar energy can help in the conservation of non-renewable sources of energy by reducing their usage.
2. Using bio-gas as fuel: Bio-gas can be used in place of coal which will help in reducing the usage of coal which is getting depleted with time.
3. Tougher laws: The government should make tougher laws to limit the usage of non-renewable sources of energy which will help in preserving them.
4. Avoiding unnecessary use of energy: Switching off appliances such as fans, bulbs, irons, air conditioners, etc when not in use can help in conserving energy.
5. Using pressure cookers: Pressure cookers use less energy and can help in conserving energy.
