Question 1(c)

Give a reason for each of the following:

(i) Non-conventional sources of energy are called the resources of the future.

(ii) India is an advantageous position in terms of solar energy.

(iii) Harvesting of solar energy does not require much maintenance.

Answer

(i) Non-conventional sources of energy are called the resources of the future as most of these sources of energy are renewable, non-polluting, less expensive to run and easy to maintain.

(ii) India in an advantageous position to harness solar energy because of India's location on the Tropic of Cancer. Most parts of the country have 300 clear sunny days in a year and per hour per square km availability of solar energy between 5 to 7 kW.

(iii) Harvesting of solar energy does not require much maintenance as most reliable solar panel manufacturers give 20-25 years warranty. Also, as there are no moving parts, there is no wear and tear. So, after covering the initial cost of the solar energy system, it requires very little spending on maintenance and repair work.
