Passage - 1

Passage: Sun rays tapped in photovoltaic cells can be converted into energy, known as solar energy. The two effective processes considered to be very effective to tap solar energy are photovoltaics and solar thermal technology. Solar thermal technology has some relative advantages over all other non-renewable energy sources. It is cost competitive, environment friendly, and easy to construct. Solar energy is 7 per cent more effective than coal or oil-based plants and 10 per cent more effective than nuclear plants. It is generally used more in appliances like heaters, crop dryers, cookers, etc. The western part of India has greater potential for the development of solar energy in Gujarat and Rajasthan.

Q1: What kind of energy is solar energy classified as?
Ans: Solar energy is the non-conventional source of energy.

Q2: Which system converts sunlight into heat energy?
Ans: Solar thermal power system converts sunlight into heat energy.

Q3: What are the benefits of using solar energy?
Ans: Solar energy is economical, has low maintenance cost, and is a truly renewable energy source.

Q4: Which states have significant potential for solar energy development?
Ans: Gujarat and Rajasthan.
