Questions Related to promotion of renewable resources

Which one of the following is an non-conventional source of energy?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Hydroelectric energy

  2. Biomass energy

  3. Solar pond

  4. Fossil fuel energy

Show answer
Correct Option: C
Explanation:
  • Solar pond is a non-conventional source of energy, which is renewable or inexhaustible and do not cause environment pollution. More over they do not require heavy expenditure. Energy generated by using wind, tides, solar geothermal heat are also non-conventional energy sources.
  • Hydroelectric energy, biomass energy and fossil fuel energy are conventional sources of energy, since they are non-renewable or exhaustible and cause environmental pollution. 
  • So the correct answer is 'Solar pond'.

Which one is a non-renewable energy resource?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Hydropower

  2. Tidal power

  3. Geothermal power

  4. Nuclear energy

Show answer
Correct Option: D
Explanation:

Non-renewable energy resource is a resource that is limited in quantity. It cannot be recycled or replenished. The examples include coal, petroleum, natural gas, nuclear energy. The renewable energy resources include hydropower (wind), tidal power (water), geothermal power (solar energy).

Thus, the correct answer is 'Nuclear energy.'

Which of the following is not a renewable source of energy?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Coal

  2. Wood

  3. Cow dung

  4. Agriculture waste

Show answer
Correct Option: A
Explanation:
Non-renewable energy sources are those that cannot be reused again as their actual form gets converted to a waste product or some other non-usable form. Coal is obtained from the Earth's crust by the decomposition of dead matter for long period of time. It is commonly used as the source of energy. There are limited deposits of coal and it takes a long time to be formed. Hence it is a non-renewable form of energy.  Thus the correct answer is option D.

Hydropower is

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Inexhaustible and renewable resource

  2. Inexhaustible and nonrenewable resource

  3. Exhaustible and nonrenewable resource

  4. Exhaustible and renewable resource

Show answer
Correct Option: A
Explanation:

Hydropower is a method of generating power by flowing water, which spins the turbines, it is a renewable source of energy and also it is inexhaustible

So, the correct answer is 'Inexhaustible and renewable resource'

Coal and petroleum are non-renewable inexhaustible resource.

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. True

  2. False

  3. Nither

  4. Either

Show answer
Correct Option: B
Explanation:

Coal and petroleum are non-renewable exhaustible natural resources as once used they are lost forever. They are not replenished by nature and their formation takes a very long period of time. 

On the other hand, inexhaustible resources are renewable resources that get replenished by nature and hence, they don't get depleted when used. For example, forests, water etc.
Hence the statement given in the question is not correct.
So, the correct answer is 'False'.

Mineral and metals are 

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Biodegradable resources

  2. Renewable

  3. Non- renewable

  4. Renewable and non - renewable resources

Show answer
Correct Option: C
Explanation:

Minerals and metals are non renewable sources of energy as depletion in it is not possible to renew again.

Thus, the correct answer is 'Non - renewable.'

The fossil fuels, coal and petroleum, will ultimately be exhauste.

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. True

  2. False

  3. Nither

  4. Either

Show answer
Correct Option: A
Explanation:
The fossil fuels, coal and petroleum will ultimately exhaust because these are non-renewable natural resources. They are not replenished by nature and once used, they are lost forever. It takes a very long time for their formation. Petroleum is produced from crude oil which takes million of years to form in the earth from the dead remains of plants and animals. Similarly, coal and fossil fuels also form in this way in million of years. Hence, they will ultimately get exhausted as the demand for these resources is increasing.
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.
