The correct answer is: a) Hydropower.
Hydropower is the most important source of electricity generation in Mizoram, accounting for over 90% of the state’s total electricity production. The state has a number of large hydropower plants, including the Tuirial Hydroelectric Project, the Bairabi Hydroelectric Project, and the Serlui Hydroelectric Project. These plants generate electricity from the state’s abundant water resources.
Thermal power (coal-based) is the second most important source of electricity generation in Mizoram, accounting for around 5% of the state’s total electricity production. The state has one thermal power plant, the Lakadong Thermal Power Plant, which generates electricity from coal.
Solar power and wind power are relatively minor sources of electricity generation in Mizoram, accounting for around 1% and 3% of the state’s total electricity production, respectively. The state has a number of small solar and wind power plants, but these plants do not generate enough electricity to meet the state’s needs.
The state government is planning to increase the share of renewable energy in the state’s electricity mix. The government has set a target of generating 10% of the state’s electricity from renewable energy sources by 2022. The government is planning to achieve this target by installing more solar and wind power plants.
