Practice questions
Q1Consider 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.
Q2With 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.
Q3With 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.
Statements 1 and 3 are correct. Anaerobic digestion produces methane-rich biogas, and second-generation ethanol can use agricultural residues such as rice straw. Statement 2 is incorrect: waste-to-energy is best used for residual waste after segregation and material recovery, not as a substitute for reduction, reuse, recycling and composting.
Q4Match 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.
Q5Consider the following statements: Statement I: Section 86(1)(e) of the Electricity Act, 2003 directs State Commissions to promote cogeneration and generation from renewable sources by specifying purchase of such electricity as a percentage of total consumption. Statement II: Article 48A is a Fundamental Right that citizens can directly enforce against the State. Which one of the following is correct in respect of the above statements?
Statement I is correct: Section 86(1)(e) places renewable-purchase promotion within State Commission functions. Statement II is incorrect because Article 48A is a Directive Principle of State Policy, not a directly enforceable Fundamental Right.
