Non Conventional Energy

Total Questions: 59

1. Which one of the following is a renewable source of energy? [M.P.P.C.S. (Pre) 2016]

(a) Coal
(b) Nuclear energy
(c) Petrol
(d) Solar energy

Correct Answer: (d) Solar energy

Solution:Solar energy is radiant light and heat from the sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy etc. It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power.

2. Which one of the following is not a fossil fuel? [M.P.P.C.S. (Pre) 2016]

(a) Coal
(b) Petroleum
(c) Natural gas
(d) Uranium

Correct Answer: (d) Uranium

Solution:Fossil fuels are non-renewable sources of energy. Fossil fuel was formed by natural processes through decomposition of the buried organism. Examples of fossil fuel include oil, coal and natural gas. Fossil fuels are the main sources of energy presently.

3. Non-conventional energy sources are those energy sources, that are- [U.P.P.C.S. (Pre) 2023]

(a) Produced from heat
(b) Produced from electricity
(c) Non-renewable electricity
(d) Renewable

Correct Answer: (d) Renewable

Solution:Non-conventional energy sources are those energy sources that are renewable. Renewable resources are those which get renewed or replenished quickly, such as solar wind energy and geothermal energy.

4. An ultimate source of energy stored in fossil fuels is: [U.P.R.O./A.R.O. (Re-Exam) (Pre) 2016]

(a) Earth
(b) Sun
(c) Sea
(d) Moon

Correct Answer: (b) Sun

Solution:Fossil fuels were formed from the dead remains of living organisms. An ultimate source of energy stored in fossil fuels is Sun.

5. The second most important source after fossil fuels contributing to Indian energy need is- [U.P.R.O./A.R.O. (Pre) 2021]

(a) Hydropower energy
(b) Wind energy
(c) Nuclear energy
(d) Solar energy

Correct Answer: (d) Solar energy

Solution:The second most important source after fossil fuels contributing to Indian energy need is solar energy. The solar energy share in total non-fossil fuel is about 12.5 per cent. Hence option(d) is correct.

6. Which one of the following is NOT an example of biomass energy source? [U.P.P.C.S. (Pre) 2022]

(a) Nuclear energy
(b) Wood
(c) Coal
(d) Gobar (Dung)

Correct Answer: (a) Nuclear energy

Solution:Biomass feedstocks include dedicated energy crops, agricultural crop residues, forestry residues, algae, wood processing residues, municipal waste, and wet waste (crop wastes, forest residues, purpose-grown grasses, woody energy crops, algae, industrial wastes, sorted municipal solid waste [MSW], urban wood waste, and food waste). Nuclear energy is usually considered another non-renewable energy source. The material most often used in nuclear power plants is uranium

7. The Decade of Sustainable Energy for all is the initiative of: [U.P.P.C.S. (Pre) 2017]

(a) United Nations
(b) India
(c) Germany
(d) World Bank

Correct Answer: (a) United Nations

Solution:Renewable energy is a form of energy that is not the cause of pollution nor has its adverse effect on natural resources. Sustainable energy is the seventh goal of the 17 UN Sus- tainable Development Goals (SDGs), with a call to ensure access to affordable, reliable, sustainable and modern energy for all by 2030. The Sustainable Energy for all initiative, acts in support of the 2014-2024 decade of Sustainable Energy for All as declared by the UN General Assembly.

8. What is meant by energy crisis? [Uttarakhand P.C.S. (Pre) 2006]

(a) Shortage of hydroelectricity.
(b) Malnutrition leading to a short supply of energy in the body.
(c) Shortage of thermal power.
(d) The danger of the extinction of fossil fuel like coal and petrol.

Correct Answer: (d) The danger of the extinction of fossil fuel like coal and petrol.

Solution:The danger of the extinction of fossil fuels like coal and crude oil is called energy crises.

9. Which one of the following is the best source of generating electricity in India from the viewpoint of sustainable development? [U.P.P.C.S.(Pre) 2012]

(a) Coal
(b) Mineral oil and gas
(c) Hydro- electricity
(d) Atomic energy

Correct Answer: (c) Hydro- electricity

Solution:Sustainable development is economic development that is conducted without the depletion of natural resources. Coal, Mineral Oil, gas and atomic energy are natural resources which are limited. Hydroelectricity uses water to produce electricity without depleting water. Hence, Hydro-electricity is the best source to generate electricity for sustainable development.

10. Which of the following renewable power resources had highest installed capacity in the country in 2014? [Chhattisgarh P.C.S. (Pre) 2015]

(a) Biomass power
(b) Solar power
(c) Waste to energy
(d) Wind power
(e) None of the above.

Correct Answer: (d) Wind power

Solution:India's installed renewable energy capacity has increased 396% in the last 8.5 years and stands at more than 180.79 GWGiga Watts (including large Hydro), which is about 42.5% of the country's total capacity (as of Dec. 2023). India saw the highest year on year growth in renewable energy additions of 9.83% in 2022. The installed solar energy capacity has increased by 24.4 times in the last 9 years and stands at 73.31 GW as of Dec., 2023. The installed Renewable energy capacity (including large hydro) has seen an increase of around 128% since 2014.
