Q1With reference to energy classification used in India, consider the following statements: 1. Non-fossil energy may include nuclear power and large hydropower. 2. Non-conventional energy is a strict scientific category identical to renewable energy. 3. Some renewable-energy tables may exclude large hydropower from their sub-totals. Which of the statements given above are correct? Select the correct answer using the code below.
Statements 1 and 3 are correct. Non-fossil energy is broader than renewable energy and may include nuclear and large hydropower, while the treatment of large hydro can vary across renewable sub-totals. Statement 2 is incorrect because non-conventional energy is an older policy expression, not a strict scientific category identical to renewable energy.
Q2Consider the following statements: Statement I: A Renewable Energy Certificate represents the green attribute of renewable electricity separately from the physical electricity. Statement II: A carbon credit represents an emission reduction or removal under a carbon scheme and may cover sectors beyond electricity. Which one of the following is correct in respect of the above statements?
Both statements are correct and describe distinct instruments. A Renewable Energy Certificate separates the environmental attribute of renewable generation from physical power, whereas a carbon credit records an emission reduction or removal under a carbon framework and is not confined to the power sector.
Q3Match List I with List II and select the correct answer using the code below. List I (Energy route) 1. Solar photovoltaic 2. Small hydropower 3. Bioenergy 4. Green hydrogen List II (Conversion mechanism) P. Organic matter is converted to heat, gas or liquid fuel Q. Renewable electricity splits water R. Light is converted directly into electricity S. Flowing water drives a turbine
Option A gives all four correct matches. Solar photovoltaic converts light directly to electricity; flowing water drives a small-hydro turbine; bioenergy converts organic matter into heat, gas or liquid fuel; and green hydrogen is produced when renewable electricity splits water.
Q4With reference to storage and renewable-grid integration, consider the following statements: 1. Pumped storage is a primary energy source whose climate value is independent of the electricity used for pumping. 2. Battery storage is modular but depends on critical minerals. 3. Inadequate demand, transmission or grid stability can lead to curtailment of available renewable generation. Which of the statements given above are correct? Select the correct answer using the code below.
Statements 2 and 3 are correct. Batteries are modular but mineral-dependent, and renewable output may be curtailed when the system cannot absorb it. Statement 1 is incorrect because pumped storage stores energy rather than supplying a primary source, and its climate value depends on the electricity used to pump water uphill.
Q5Match List I with List II and select the correct answer using the code below. List I (Instrument) 1. Renewable Purchase Obligation 2. Renewable Energy Certificate 3. Carbon credit 4. Net metering List II (Function) P. Allows a consumer to export surplus rooftop electricity to the grid Q. Requires obligated entities to buy a specified renewable share R. Credits an emission reduction or removal S. Separates the green attribute from physical electricity
Option C is correct. A Renewable Purchase Obligation mandates a specified renewable share; a Renewable Energy Certificate separates the green attribute from electricity; a carbon credit records an emission reduction or removal; and net metering enables export of surplus rooftop power. The other options interchange these distinct functions.

6With reference to solar-energy systems, consider the following statements: 1. Solar photovoltaic cells convert light directly into electricity. 2. Concentrated solar power uses mirrors to produce heat that can drive a turbine or provide process heat. 3. Daytime solar capacity cannot replace firm capacity one-for-one unless balancing arrangements handle demand at other times. Which of the statements given above are correct? Select the correct answer using the code below.
7With reference to bioenergy pathways, consider the following statements: 1. Anaerobic digestion of cattle dung, food waste or sewage sludge can produce methane-rich gas. 2. Waste-to-energy should replace reduction, reuse, recycling and composting in the waste hierarchy. 3. Second-generation ethanol can use lignocellulosic biomass such as rice straw. Which of the statements given above are correct? Select the correct answer using the code below.

10Arrange the following stages in the operation of a pumped-storage system in the correct order: 1. Water is released from the upper reservoir 2. Electricity is used to pump water upward 3. Released water generates electricity 4. Water is held in the upper reservoir until required Select the correct answer using the code below.
