Question

An inexhaustible non-conventional universal source of energy is

• A. Wind energy
• B. Solar energy
• C. Hydrothermal energy
• D. Tidal energy

Answer 1

The correct option is B Solar energy

Solar energy is considered to be the non-conventional because it is not derived from the conventional fossil fuels. It is inexhaustible as it will not be used up completely. It will not take much time in regeneration. It is universal as most of the places on earth that sustain a large population get the sunlight. Wind energy is also non-conventional and inexhaustible but it is not available to every area. It can be harnessed in areas that witness a low pressure, like equatorial and tropical areas. Similarly, the tidal energy is available to the coastal areas. Hydrothermal resources are available everywhere but need a heavy economic investment for their usage.

Hence, the correct answer is 'Solar energy'.
