Renewable Energy Sources Questions and Answers

Q: Based on the 'Renewables 2023' report by International Energy Agency, which of the following type of renewable energy, made the highest renewable electricity capacity additions, between the years 2016 to 2023 ?

The largest additions came from solar PV.The International Energy Agency's Renewables 2023 report shows solar photovoltaics accounting for by far the largest share of renewable capacity added worldwide in recent years, about three-quarters of the additions in 2023, well ahead of wind.Wind is second, while geothermal and ocean energy add only small amounts of capacity.Solar's lead comes from steep falls in the cost of panels, which have made it the cheapest source of new electricity in many countries.

Q: Which state has the highest potential for the development of solar energy ?

The state with the highest solar energy potential is Rajasthan.The National Institute of Solar Energy assessed India's solar potential at about 748 GW, and Rajasthan has the largest share, around 142 GW, thanks to its abundant wasteland and some of the highest solar radiation and clear-sky days in the country.Madhya Pradesh also has large potential but less than Rajasthan, while Jharkhand and Uttar Pradesh are well behind among these options.

Q: Jharkhand is rich in renewable resources because of

The key's answer is Abundance of waterfalls.The question follows the Jharkhand State Action Plan on Climate Change, which says the state is rich in both renewable and non-renewable energy resources, 'with abundance of water-falls, rivers, nuclear minerals and huge coal reserve'. Of the options, only the waterfalls are a renewable resource that the plan names.Coal reserves (A) and minerals in igneous rocks (C) are non-renewable resources. Forests (D) are renewable too, but the plan does not give forests as the reason in that passage, so the key's reading, taken from the plan, is B.

Q: "Consistent availability of sufficient energy in various forms at affordable prices" is the definition of :

It is the definition of energy security.Energy security, in the International Energy Agency's formulation, is the uninterrupted availability of energy sources at an affordable price. The definition in the question has the same two elements: a consistent, sufficient supply in usable forms, and prices people and industry can afford.Energy conservation is reducing energy use by avoiding waste. Energy management is the systematic monitoring and control of energy use in an organisation, and energy policy is the set of government decisions about producing, distributing and using energy. None of these is defined by availability at affordable prices.

Q: The online platform established by the Ministry of New and Renewable Energy for Installation of Solar Photovoltaic :

The platform is SPIN.SPIN is the online platform launched by the Ministry of New and Renewable Energy in 2019 to simplify and speed up the approval, installation and subsidy release for rooftop solar photovoltaic projects under the rooftop solar programme. Applications, inspections and payments are tracked online, which cuts delays.SOLARWHIN, SPINE and INSP are not MNRE platforms. They are look-alike acronyms meant to catch a candidate who remembers only that the name was short and began with 'S'.

Q: Biomass gasification is considered to be one of the sustainable solutions to the power crisis in India. In this context, which of the following statements is/are correct ?(i) Coconut shells, groundnut shells and rice husk can be used in biomass gasification.(ii) The combustible gases generated from biomass gasification consist of hydrogen and carbon dioxide only.(iii) The combustible gases generated from biomass gasification can be used for direct heat generation but not in internal combustion engines.Which of the statements given above is/are correct ?

Only statement (i) is correct, so the answer is (i) only.Biomass gasification partially burns agricultural residues such as coconut shells, groundnut shells and rice husk in limited air to produce a combustible 'producer gas' (i).Statement (ii) is wrong: the gas is mainly carbon monoxide and hydrogen, with some methane, diluted by nitrogen and carbon dioxide. Carbon dioxide is not even combustible. Statement (iii) is wrong too: after cleaning and cooling, producer gas can run internal combustion engines, either gas engines alone or diesel engines in dual-fuel mode, which is how small gasifier power plants generate electricity. So every option containing (ii) or (iii) is wrong.

Q: This is not an objective of National Green Hydrogen Mission

The statement that is not an objective is to promote hydrogen weapons over other nuclear weapons.The National Green Hydrogen Mission, approved in January 2023, is a clean-energy programme. It aims to make India a global hub for the production, use and export of green hydrogen and its derivatives, to make green hydrogen competitive with fossil-fuel based alternatives in sectors such as refining and fertilisers, and to make India self-reliant through clean energy, contributing to the global energy transition.Green hydrogen is hydrogen produced by splitting water with renewable electricity. A hydrogen weapon is a thermonuclear bomb, which has nothing to do with the Mission, so this is plainly the odd one out.

Q: Wind energy is a source of energy, which is :

Wind energy is renewable.Wind is produced by the uneven heating of the earth's surface by the sun, so it is replenished continuously and cannot be used up by drawing on it. Energy sources of this kind, like solar, hydro and biomass energy, are called renewable.Non-renewable sources such as coal and oil exist in finite stocks. 'Thermal' and 'nuclear' describe how some power stations generate electricity (by burning fuel or by fission), not wind energy.

Q: The advantage of solar cooker is :

The advantage is that the nutrition value is maintained.A solar cooker heats food slowly at moderate temperatures, without direct flame, so less of the heat-sensitive nutrients (some vitamins in particular) are destroyed than in high-temperature cooking. It also uses free sunlight and causes no smoke or pollution.A high cost would be a disadvantage, not an advantage, and solar cookers are in fact cheap to run. Slow solar cooking preserves nutrients rather than destroying them, so the remaining options are wrong.

Based on the 'Renewables 2023' report by International Energy Agency, which of the following type of renewable energy, made the highest renewable electricity capacity additions, between the years 2016 to 2023 ?

A.Geothermal
B.Ocean
C.Solar PV
D.Wind

Exam Year(s)

CBSE Assistant Secretary - 2024,

Answer: C

The largest additions came from solar PV.

The International Energy Agency's Renewables 2023 report shows solar photovoltaics accounting for by far the largest share of renewable capacity added worldwide in recent years, about three-quarters of the additions in 2023, well ahead of wind.

Wind is second, while geothermal and ocean energy add only small amounts of capacity.

Solar's lead comes from steep falls in the cost of panels, which have made it the cheapest source of new electricity in many countries.

At the headquarters of which international organisation was the Gandhi Solar Park (GSP) recently inaugurated ?

A.United Nations
B.World Health Organization
C.International Atomic Energy Agency
D.International Monetary Fund

Exam Year(s)

Kerala PSC KAS - 2020,

Answer: A

The Gandhi Solar Park was inaugurated at the headquarters of the United Nations.

In September 2019, to mark the 150th birth anniversary of Mahatma Gandhi, India gifted a solar installation on the roof of the UN headquarters in New York, with 193 panels, one for each member state, and about 50 kW of capacity. It was inaugurated during the UN General Assembly session as a symbol of India's commitment to renewable energy.

The World Health Organization, the International Atomic Energy Agency and the International Monetary Fund are headquartered in Geneva, Vienna and Washington, and none hosts the Gandhi Solar Park.
