Energy Scenario and Policy Questions and Answers

Answer: A

Correct answer: 60 per cent

The maximum possible generation is the capacity running continuously: \[ 500\ \mathrm{MW} \times 8760\ \mathrm{h} = 4{,}380{,}000\ \mathrm{MWh} = 4380\ \mathrm{GWh}, \qquad \frac{2628}{4380} = 0.60. \] The 8760 hours in a year is the constant to have ready; every plant load factor and capacity utilisation calculation runs through it.

Answer: B

A fixed solar plant in India achieves something around a fifth of its rated output over a year because the sun sets and clouds pass. Comparing installed capacities between the two technologies without that correction badly overstates the renewable contribution.

Answer: C

Separating generation, transmission and distribution, licensing them and permitting large consumers to buy from a supplier of their choice was the central change. The efficiency institutions were created by the separate Energy Conservation Act of 2001.

Answer: D

The network is made available on payment of wheeling and other charges, which introduces competition into supply while leaving the wires a regulated monopoly. Cross-subsidy surcharges have limited how far it has been used in practice.

Answer: A

Correct answer: source a stated share of its energy from renewable generation

A renewable purchase obligation sets the minimum fraction of a licensee’s energy that must come from renewable sources, and the obligation can be met by buying that power or by buying renewable energy certificates from someone who generated more than their own share. It creates demand rather than supply, which is why it works alongside rather than instead of generation incentives.

Answer: B

Selling the electricity at the ordinary rate and the attribute as a certificate lets a generator in a windy state serve an obligation in a state with no wind. Energy saving certificates and carbon credits belong to separate schemes with separate units.

Answer: C

A star rating on a refrigerator or an air conditioner lets a buyer weigh purchase price against running cost, and raising the thresholds over time withdraws the worst models. It works through information and minimum standards rather than through price.

Answer: D

Prescribing wall and roof insulation, glazing performance, lighting power density and equipment efficiency at the design stage locks in the consumption for the building's whole life. Retrofitting the same performance later costs several times as much.

Answer: A

The missions cover solar energy, enhanced energy efficiency, water, sustainable habitat, agriculture, the Himalayan ecosystem, a green India and strategic knowledge. The efficiency mission is the vehicle for the trading scheme and the appliance programmes.

Answer: B

The architecture is bottom-up: each country states what it will do and is reviewed rather than assigned a target, with the contributions expected to strengthen over successive cycles. India's includes an emissions intensity target and a non-fossil capacity share.
