Hints

Open one hint at a time and try again before the next.

Hint 1

Are energy resources unlimited?

Hint 2

What happens to the demand for energy if we avoid wasting it?

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. Energy resources are limited, so we urgently need a sustainable path of development. Saving energy reduces the demand for new production and so is equal to producing it.

    1 mark

  2. Energy conservation, judicious use, the 3 Rs (reduce, reuse, recycle) and greater use of renewable sources stop wastage and preserve resources for the future.

    1 mark

Answer: Saving energy cuts demand and wastage, making limited resources last longer, which is equivalent to producing energy.

Where the marks are

  • Need for sustainable development or judicious use of limited energy (1 mark)
  • Conservation, renewables, reduce-reuse-recycle, stopping wastage (1 mark)
