Karnataka is a pioneer in this field of renewable energy:

Solar
Hydroelectric
Geothermal
Wind

The correct answer is: A) Solar

Karnataka is a pioneer in the field of solar energy. The state has the largest installed capacity of solar power in the country, with over 5,000 MW of capacity. Karnataka is also home to the world’s largest solar park, the Pavagada Solar Park, which has a capacity of 2,050 MW.

The state government has been supportive of the development of solar energy, and has offered a number of incentives to developers. These incentives include a capital subsidy of up to 30% of the project cost, and a power purchase agreement (PPA) with the state government at a tariff of Rs. 2.50 per kWh.

The development of solar energy in Karnataka has had a number of benefits. It has helped to reduce the state’s dependence on fossil fuels, and has created jobs in the solar industry. Solar energy has also helped to improve air quality in the state.

However, there are some challenges to the development of solar energy in Karnataka. One challenge is the high cost of solar panels. Another challenge is the lack of land availability for solar projects. The state government is working to address these challenges, and is confident that solar energy will continue to play a major role in the state’s energy mix.

Here is a brief explanation of each option:

  • Solar energy is energy from the sun. It is a renewable energy source that can be used to generate electricity, heat water, and power vehicles. Solar energy is becoming increasingly popular as a way to reduce our reliance on fossil fuels.
  • Hydroelectric energy is energy from moving water. It is a renewable energy source that can be used to generate electricity. Hydroelectric dams are the most common type of hydroelectric power plant.
  • Geothermal energy is energy from the Earth’s heat. It is a renewable energy source that can be used to generate electricity, heat buildings, and cool buildings. Geothermal power plants are located in areas where the Earth’s heat is close to the surface.
  • Wind energy is energy from the wind. It is a renewable energy source that can be used to generate electricity. Wind turbines are the most common type of wind power plant.
