Which of the following energy source is most costly?

  1. Thermal Energy

  2. Hydel Energy

  3. Solar Energy

  4. Fossil Energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Harnessing hydel power / energy is very costly procedure due to construction of large dams across the streams, clearance of vegetation for the development of the project, rehabilitation of the people living nearby the water bodies.

  1. True

  2. False

  3. Ambiguous

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

Answer is A.

It is because they are actually fossils. They are made of dead and decay matter buried under the earth for many years. The dead and decaying matter under great amount of pressure and temperatures turn into fossils and they both are used as fuels so it is called fossil fuels.
The fossil fuels we use today are actually formed from plants and animals that existed hundreds of millions of years ago. The reason there is a lot of concern surrounding the expenditure of these resources is because most of what we use today from fossil fuels, such as oil and coal are being depleted much faster than they can be formed, so there is a limited amount available.
Hence, the statement is true.
