Total Questions: 59

11. Which of the following is a renewable source of energy? [C.G.P.S.C. (Pre), 2018]

Correct Answer: (c) Biomass
Solution:Biomass is renewable organic material that comes from plants and animals. Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes. Biomass sources for energy include:

• Wood and wood processing wastes-firewood, wood pellets, and wood chips, lumber and furniture mill sawdust and waste, and black liquor from pulp and paper mills

• Agricultural crops and waste materials-corn, soybeans, sugar cane, switchgrass, woody plants, and algae, and crop and food processing residues, mostly to produce biofuels

• Biogenic materials in municipal solid waste-paper, cotton, and wool products, and food, yard, and wood wastes

• Animal manure and human sewage for producing biogas/ renewable natural gas.

12. A non-renewable sourced of energy is: [U.P.P.C.S. (Pre) 2021]

Correct Answer: (b) Petroleum
Solution:Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.

Fossil fuels - coal, oil and gas - on the other hand, are non- renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide.

13. Which of the major source of power in Chhattisgarh? [C.G.P.S.C. (Pre), 2018]

Correct Answer: (a) Thermal power
Solution:Chattisgarh is rich in energy resources. Thermal power is the major source of Energy in Chhattisgarh. Thermal Power Plants in India are the cornerstone of India's energy sector, contributing approximately 78% of the country's total electricity supply. Thermal Power Plants in India provide critical base-load power, which promotes industrial growth and infrastructure development. While providing energy security and affordability, they also help to balance intermittent renewable energy sources.

Thermal Power Plants in India in 2024 had a capacity of 243.21 GW, with coal-based plants dominating at 210.96 GW. The nation aims to diversify its energy mix by 2030, aiming for 500 gigawatts (GW) of non-fossil electricity. However, their reliance on fossil fuels raises environmental concerns, necessitating the development of cleaner technologies and a shift to a more sustainable energy mix.

14. Among the following energy sources which one is used maximum in organic form? [U.P.P.C.S.(Mains) 2004]

Correct Answer: (b) Solar Energy
Solution:Solar technologies use clean energy from the sun rather than polluted fossil fuels. There are two main types: solar thermal, which uses solar energy to heat water, and solar photovoltaic (PV), which uses solar cells to transform sunlight into electricity.

Global solar adoption is increasing as a result of declining costs and expanding access to clean energy (SDG 7). India can achieve its climate commitments in an environmentally sustainable manner, lessen its dependency on imported fuels, and promote social inclusion (SDG 10) by expanding access to solar applications and increasing solar capacity to 450 GW by 2030. Because of its boundless potential, solar energy is a vital ally for sustainable development.

Solar energy utilises the sun's radiant light and heat to generate useful energy services like electricity, heating, cooling, lighting, or mechanical work. In recent years, solar technology has emerged as an important renewable energy source with significant potential to meet the world's energy needs in an eco-friendly manner.

15. Which of the following is the largest storehouse of alternative energy? [40th B.P.S.C. (Pre) 1995]

Correct Answer: (a) Solar Energy

18. Which of these natural resources is considered as non- renewable resource? [Raj. P.C.S. (Pre) 2023]

Correct Answer: (b) Fossil Fuels
Solution:Fossil fuels are non-renewable, meaning they are formed over millions of years and cannot be replenished at the rate they are consumed. Once they are depleted, they will be gone. Many economies and industries heavily rely on fossil fuels for energy production, transportation, and various industrial processes. A sudden or significant reduction in fossil fuel availability can disrupt these systems and lead to energy shortages.

The price of fossil fuels can fluctuate significantly based on supply and demand. An energy crisis can lead to higher energy prices, impacting businesses and consumers, potentially causing inflation and economic slowdown. The extraction and burning of fossil fuels contribute to air pollution and climate change. A decline in fossil fuel availability may lead to a search for alternative energy sources, potentially with their own environmental impacts, such as renewable energy projects.

19. Which one of the following energy sources is the best in keeping environment clear? [U.P.P.C.S. (Pre) 2015]
