  3. Natural gas

  4. Biogas

Show answer
Correct Option: B
Explanation:

These are different ranks of coal which is non renewable source of energy.

State True or False :
Electricity is exclusively a non-renewable resource.

physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Electricity can be produced by another energy sources. It is not a primary energy form. It can be generated from renewable as well non-renewable sources of energy.

Choose the correct statement.

physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

  1. Power of  magnets in hydro power plants increases with time.

  2. Magnets are involved in the generation of electricity in hydro power plants.

  3. In hydro power plants, magnetic energy is converted into electrical energy.

  4. In hydro power plants, electrical energy is converted into magnetic energy.

Show answer
Correct Option: B
Explanation:

Magnets slowly lose their strength with time.

In hydro power plants, kinetic energy from water is converted to electrical energy. This is done with the help of magnets. A coil is rotated (from kinetic energy of water) between two magnets to generate electricity.

Which of these is not related to energy efficiency?

physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

  1. Useful energy

  2. $kW$

  3. Heat

  4. Energy transformation

Show answer
Correct Option: B
Explanation:

Energy efficiency measures how much of energy is put into device to do intended job. So, it is related to useful energy, heat and energy transformation.
$kW$ or kilowatts are unit used to measure amount of electric power.

Which of following is not a renewable source of energy?

physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

  1. Geothermal

  2. Propane

  3. Solar

  4. Wind

Show answer
Correct Option: B
Explanation:

Propane was formed millions of years ago by decay of dead tiny plants and animals that sank to the bottom of ocean. It is in limited in supply.

Production of electricity by wave energy requires:

physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

  1. extremely strong pipes to carry sea water in huge waves.

  2. devices to trap wave energy for rotation of turbine.

  3. devices to boil sea water in waves.

  4. all of the above.

Show answer
Correct Option: B
Explanation:

Wave energy requires devices to trap the energy. A wide variety of devices have been developed to trap wave energy for rotation of turbine and production of electricity.
