Solution
- Yes, saving energy is the need of the hour because energy demand is increasing rapidly due to population growth, industrialisation, and technological development.
- Most of the energy we use comes from non-renewable sources such as coal, petroleum, and natural gas, which are limited and may be exhausted in the future. Excessive use of these fuels also causes pollution and environmental problems.
- By saving energy, we can conserve natural resources, reduce pollution, lower energy costs, and ensure energy availability for future generations.
Therefore, saving energy is essential for sustainable development and environmental protection.
