Model Answer

Conservation of energy means using resources carefully so that less new energy needs to be generated. When we save electricity by switching off lights, or use fuel-efficient vehicles, we reduce the demand for energy production. This saving is equivalent to producing new energy, since the same work is done with less resource extraction and generation. Thus, conservation effectively acts as a source of energy.

Explanation

The examiner expects you to link saving/conserving energy directly to reduced need for production, making conservation equivalent to production. Key idea: every unit saved = a unit that didn't need to be produced. Avoid vague points about environment; keep the logical link tight. This is a 2-mark inference-based question, so one clear explanation with a supporting example is sufficient.
