Multiple choice physics towards green energy non-conventional sources of energy electric energy generation and environment renewable and non-renewable energy

Common source of energy used for cooking in rural parts of India is:

  1. Sun

  2. Coal

  3. Wood and animal dung

  4. None of the above 
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Wood and animal dung are major source of energy for cooking in rural areas. It is readily available and is cheap form of energy, while solar energy is not abundantly used because its difficult to harness solar energy and coal is not cost efficient.

Geothermal energy can be best described as:

  1. light energy from Sun.

  2. heat energy from rocks inside Earth's surface. 

  3. heat energy from temperature difference in tides.

  4. heat energy from combustion of minerals.

B Correct answer
Explanation

Geothermal energy is heat from within the Earth. The core and lower part of mantle generates large amount of heat. Deep, super heated water present, can be pumped to surface and used to produce electricity.

C Correct answer
Explanation

All the sources of energy are directly or indirectly derived from the ultimate source of energy. i.e. Sun, except for the nuclear energy. Nuclear energy is derived from the molecules of the radioactive elements.

State whether the given statement is True or False :
Solar panel can be set up in remote and inaccessible hamlets or very sparsely inhabited areas. 

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Solar panels are ideal for remote areas because they do not require a connection to a centralized power grid. They can generate electricity locally using sunlight, making them a practical solution for sparsely inhabited regions.

Of the following, renewable source of energy is

  1. Wood

  2. Petroleum

  3. Natural gas

  4. Uranium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wood is a renewable source of energy because it can be replenished by planting new trees. Petroleum, natural gas, and uranium are finite fossil or mineral fuels that cannot be replaced on a human timescale.

The sources of energy which are being produced continuously in nature and are inexhaustible, are called

  1. Conventional sources

  2. Non-renewable sources

  3. Non-conventional sources

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sources of energy that are inexhaustible and produced continuously in nature are generally classified as non-conventional or renewable sources. Conventional sources like coal and petroleum are finite and exhaustible.
