Question : Why is conservation of minerals important? How can we conserve minerals?
Answer :   Conservation of minerals is important for the following reasons.

(i) Minerals are exhaustible.

(ii) They are limited in availability.

(iii) Minerals have manifold uses.

(iv) Growth of industrialisation has accelerated the extraction of minerals.

We can conserve minerals by making an efficient use of them and using recyclable sources of energy wherever possible.

Question : Describe any three non-conventional sources of energy.
Answer :   Non-conventional sources of energy are :

(i) Solar Energy : India is a tropical country. It has enormous possibilities of trapping solar energy. Photovoltaic technology converts sunlight directly into electricity. Solar energy is quickly becoming popular in rural and remote areas.

(ii) Wind Energy : India now ranks as a 'wind super power' in the world. Andhra Pradesh, Karnataka, Gujarat, Kerala, Maharashtra and Lakshadweep have important wind farms. Nagericoil and Jaisalmer are well-known for effective use of wind energy in the country.

Question : There is an urgent need to develop a sustainable path of energy development. Give two broad measures for it. As concerned citizens, how can you help to conserve energy?
Answer :  Need to use renewable energy resources are :

(i) The growing consumption of energy has resulted in the country becoming increasingly dependent on fossil fuels such as coal, oil and gas.

(ii) Rising prices of oil and gas and their potential shortages have raised uncertainties about the security of energy supply in future.

(iii) Has serious repercussions on the growth of our country.

(iv) Hence, there is a pressing need to use renewable energy source like solar energy, wind, tide, biomass and energy from waste material.
