(D) Geothermal Energy
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A), (B) and (D) only
Conventional sources of energy, such as coal, petroleum and natural gas, have been in wide use for a long time and are mostly exhaustible. Non-conventional sources are newer, renewable sources, such as the sun, wind, tides, the earth’s heat and biogas.
(A) Wind Power Correct. Wind turbines turn the energy of moving air into electricity, and the wind never runs out.
(B) Tidal Energy Correct. The rise and fall of the tides drives turbines placed across narrow creeks or bays.
(C) Natural Gas Incorrect. Natural gas is a fossil fuel, found with petroleum, and is a conventional source that will run out.
(D) Geothermal Energy Correct. It uses the heat inside the earth, as at the Puga valley in Ladakh and Manikaran in Himachal Pradesh.
