Hints

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

Hint 1

Which sectors of the economy cannot function without energy?

Hint 2

How long does coal take to form, and can we make more quickly?

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 is a basic requirement for economic development. Agriculture, industry, transport, commerce and homes all need energy inputs, and its consumption keeps rising, so a sustainable path of energy use is urgently needed.

    1 mark

  2. Conventional sources such as coal and petroleum took millions of years to form. They are exhaustible and cannot be replaced quickly, so they must be conserved for future generations.

    1 mark

Answer: Conservation is significant because development in every sector depends on energy, and conventional sources like coal are non-renewable, taking millions of years to form.

Where the marks are

  • Energy is essential for development of all sectors (1 mark)
  • Conventional sources are exhaustible and need millions of years to form (1 mark)
