Read the given case and answer the questions that follow:

CONSERVATION OF ENERGY RESOURCES

Energy is a basic requirement for economic development. Every sector of the national economy – agriculture, industry, transport, commercial and domestic – needs inputs of energy. The economic development plans implemented since independence necessarily required increasing amounts of energy to remain operational. As a result, consumption of energy in all forms has been steadily rising all over the country. In this background, there is an urgent need to develop a sustainable path of energy development. Promotion of energy conservation and increased use of renewable energy sources are the twin planks of sustainable energy. India is presently one of the least energy efficient countries in the world. We have to adopt a cautious approach for the judicious use of our limited energy resources. For example, as concerned citizens we can do our bit by using public transport systems instead of individual vehicles; switching off electricity when not in use, using power-saving devices and using non-conventional sources of energy. At last "Energy Saved is energy produced".

Hints

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

Hint 1

Which sectors of the economy depend on energy?

Hint 2

Think of development, population and living standards.

Hint 3

Saving a unit of energy means one less unit has to be generated.

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. (35.1) Energy is a basic requirement for economic development. Every sector of the economy needs energy, so future sustenance depends on conserving energy and using it sustainably.

    1 mark

  2. (35.2) Energy consumption is rising because of economic development, rising population, rising incomes and improving standards of living, and technological developments.

    1 mark

  3. (35.3) Saving energy through public transport, switching off appliances when not in use and using power-saving devices reduces the need to produce more energy.

    1 mark

  4. (35.3) Using renewable sources and the principle of reduce, reuse and recycle improves energy security and access. Energy saved therefore equals energy produced.

    1 mark

Answer: (35.1) Every sector needs energy, so its conservation sustains development. (35.2) Economic development, population growth, rising incomes and technology. (35.3) Saving energy reduces the need for new production and conserves limited resources.

Where the marks are

  • Explains why sustainable energy is key to development (1 mark)
  • Gives a reason for rising energy consumption (1 mark)
  • Explains energy saved with conservation habits (1 mark)
  • Adds renewable energy or reduce, reuse and recycle, and links to energy security (1 mark)
