Q. With reference to India’s energy sector history, consider the following pairs:

1. First hydroelectric plant in India - Sidrapong, Darjeeling (1897)
2. Asia's first nuclear plant - Tarapur (1969)
3. World's oldest still-producing oilfield - Digboi (1889)
4. World's largest solar park - Bhadla
5. World's largest coal producer - Coal India

How many of the above pairs are correctly matched?
Answer: Only 3
Notes: Sidrapong in Darjeeling (1897) is India’s first hydro plant. Tarapur (1969) is not Asia’s first nuclear power plant. Asia's first nuclear plant was Apsara, a research reactor that became operational in August 1956 at the Bhabha Atomic Research Centre (BARC) in Trombay. Digboi oilfield (1889) is the world’s oldest still producing oilfield. The world's largest solar park is currently the Gonghe Talatan Solar Park in China, with a massive capacity of 15,600 megawatts (MW). Prior to this, the title was held by Bhadla Solar Park in India, which has a capacity of 2,245 MW and was the largest photovoltaic solar park in the world as of 2022. Coal India is the world’s largest coal producer. Only 3 are correct.
