Question

Among the below options, which are the nonconventional sources of energy?
A) Wind energy
B) Bio-gas
C) All of those
D) solar power

Answer 1

Hint: Exhaustible energy sources which are being produced continuously in nature are known as the nonconventional energy or renewable sources of energy. A number of these sources include solar power, wind energy and tidal energy. The traditional energy sources are basically supported fossil fuels which have finite reserves in nature and hence would become extinct in future.

Complete answer: Energy is the basic and most universal measure for all types of work by citizenry and nature. Everything that happens on the planet is due to the expression of flow of energy in any of its forms.
Different non-conventional sources
A) solar power - Solar power is the most readily available and free source of energy. Solar power is often utilized through two different routes, as solar thermal route and solar electric (solar photovoltaic) routes.
B) Wind energy - Wind energy is about harnessing wind generation to supply electricity. The K.E. of the wind is converted to electricity.
C) Hydro energy - The potential power of falling water is captured and converted to energy by waterwheels.
D) Bio energy - Bio-energy, is found in the form of biogas which springs from biomass. Biomass is a kind of renewable energy resource derived from the carbonaceous waste of varied human and natural activities.
E) Ocean energy - This energy is very important as it gives us two sorts of energy: thermal energy from the sun's heat, and energy from the tides and waves.
Advantages of Non-conventional energy
A) Non-conventional energy is an indigenous energy source available in considerable quantities.
B) the facility plants supported renewable don't have any fuel cost and hence negligible running cost.
C) Renewable energy sources have low energy density and more or less there's no pollution or ecological balance problem.
D) Short gestation and low investment.

Thus, all the given options are right. Hence, the right option is C.

Note: In India, DNES known as the Department of Non-Conventional Energy Sources was developed within the Ministry of Energy in 1982. The Department was later upgraded into a separate Ministry of Non-Conventional Energy Sources (MNES) in 1992. Later it was rechristened as the Ministry of New and Renewable Energy (MNRE) in October, 2006.
