1.	Which of the following are termed as non-conventional sources of energy:1. Solar energy2. Wind energy3. Tidal energyChoose the correct code-1. 1 and 2 only2. 2 and 3 only3. 1 and 3 only4. All of the above
Answer» Correct Answer - Option 4 : All of the above The correct answer is All of the above. There are commercial and non-commercial sources of energy. Commercial sources are coal, petroleum and electricity as they are bought and sold. Non-commercial sources of energy are fuelwood, agricultural waste and dried dung. These are non-commercial as they are found in nature/forests. While commercial sources of energy are generally exhaustible (with the exception of hydropower), non-commercial sources are generally renewable. More than 60 per cent of Indian households depend on traditional sources of energy for meeting their regular cooking and heating needs. Both commercial and non-commercial sources of energy are known as conventional sources of energy. There are three other sources of energy which are commonly termed as non-conventional sources — solar energy, wind energy and tidal power. Being a tropical country, India has almost unlimited potential for producing all three types of energy if some appropriate cost-effective technologies are used. Even cheaper technologies can be developed.
