AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

Q1. [3] deep thorough-understanding
A student argues: 'Saving energy is not as useful as producing more energy, because saving does not add to the total supply.' Using your understanding of energy resources and their limitations, explain why this argument is flawed.

Model Answer

The student's argument is flawed because energy conservation directly reduces demand on limited energy resources, effectively extending their supply. India's conventional energy sources — coal, petroleum, and natural gas — are finite and non-renewable. Saving energy means existing reserves last longer, which is equivalent to adding to the available supply.

The textbook states: "energy saved is energy produced." Conservation also reduces environmental damage caused by burning fossil fuels. By using public transport, switching off unused electricity, and adopting power-saving devices, we ensure sustainable use of resources — making conservation as valuable as, if not more important than, producing new energy.
