Questions Related to towards green energy

Define renewable sources of energy.

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

  1. A source whose energy supplied can be renewed is called renewable source of energy.

  2. A source of energy which will exhaust in future is called renewable source of energy.

  3. A natural source providing us energy which takes long time to replenish.

  4. A source of energy which causes environmental pollution is called renewable source of energy.

Show answer
Correct Option: A
Explanation:

A natural source of energy that can provide us energy continuously without being exhausted is called a renewable source of energy.

Which of the following is not ultimately derived from the Sun's energy?

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

  1. geothermal energy

  2. wind energy

  3. nuclear energy

  4. bio-mass.

Show answer
Correct Option: C
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.
