The major non-conventional energy source being harnessed in Karnataka:

Solar energy
Wind energy
Biomass energy
Geothermal energy

The correct answer is: A) Solar energy

Solar energy is the major non-conventional energy source being harnessed in Karnataka. The state has a large installed capacity of solar power plants, and is one of the leading states in the country in terms of solar power generation. The state government has also been promoting solar energy through various initiatives, such as the installation of solar panels on government buildings and providing subsidies to consumers for installing solar rooftop systems.

Solar energy is a clean and renewable source of energy that can help to reduce the state’s dependence on fossil fuels. It is also a cost-effective source of energy, and the state government’s initiatives have made it more affordable for consumers to install solar panels.

The other options are incorrect because:

  • Wind energy is not the major non-conventional energy source being harnessed in Karnataka. The state has a relatively small installed capacity of wind power plants.
  • Biomass energy is not the major non-conventional energy source being harnessed in Karnataka. The state has a relatively small installed capacity of biomass power plants.
  • Geothermal energy is not a major non-conventional energy source being harnessed in Karnataka. The state does not have any geothermal power plants.
