The primary source of electricity generation in Kerala is:

Hydropower
Thermal power
Solar power
Wind power

The primary source of electricity generation in Kerala is hydropower. In 2020, hydropower accounted for 54.8% of the state’s electricity generation, followed by thermal power (32.5%), solar power (10.9%), and wind power (1.8%).

Hydropower is a type of renewable energy that uses the power of moving water to generate electricity. It is one of the most efficient and cost-effective forms of renewable energy, and it has a long history of use in Kerala. The state’s first hydroelectric power plant was commissioned in 1905, and there are now over 20 hydropower plants in Kerala.

Thermal power is a type of non-renewable energy that uses the heat from burning fossil fuels to generate electricity. It is the most common form of electricity generation in Kerala, and it accounts for the majority of the state’s electricity generation. However, thermal power is a major source of greenhouse gas emissions, and it is not a sustainable form of energy.

Solar power is a type of renewable energy that uses the sun’s energy to generate electricity. It is a rapidly growing form of energy, and it is expected to play a major role in Kerala’s future energy mix. The state has a significant amount of solar potential, and there are now over 100 solar power plants in Kerala.

Wind power is a type of renewable energy that uses the wind’s energy to generate electricity. It is a clean and sustainable form of energy, and it is growing in popularity in Kerala. The state has a significant amount of wind potential, and there are now over 20 wind power plants in Kerala.

In conclusion, the primary source of electricity generation in Kerala is hydropower. Hydropower is a clean and sustainable form of energy, and it has a long history of use in the state. Thermal power is the most common form of electricity generation in Kerala, but it is a major source of greenhouse gas emissions. Solar power and wind power are both growing in popularity in Kerala, and they are expected to play a major role in the state’s future energy mix.
