The correct answer is: a) Increased hydropower generation.
Sikkim has set ambitious targets to increase the share of renewable energy in its energy mix. This is primarily through increased hydropower generation. Hydropower is a clean and sustainable source of energy that has been used in Sikkim for many years. The state has a number of hydropower plants, and the government is planning to build more in the future. Hydropower is a reliable source of energy, and it can help to reduce Sikkim’s reliance on imported fossil fuels.
Option b) Large-scale solar power projects is incorrect because Sikkim does not have a lot of land that is suitable for solar power projects. The state is mountainous, and most of the land is covered in forest. Solar power projects would require clearing forests, which would have a negative impact on the environment.
Option c) Wind farms is incorrect because Sikkim does not have a lot of wind. The state is located in the Himalayas, and the mountains block the wind. Wind farms would not be a viable option for generating electricity in Sikkim.
Option d) Waste-to-energy plants is incorrect because Sikkim does not produce a lot of waste. The state has a very low population density, and people in Sikkim are very conscious about the environment. They recycle and compost most of their waste. Waste-to-energy plants would not be a cost-effective way to generate electricity in Sikkim.
