Which of the following is NOT a benefit of generating electricity with the help of "Mini-hydel" plants?

None of the above

The correct answer is Option 4:None of the above

Explanation: Mini-hydel plants, or small hydroelectric power plants, offer several benefits:

• Environment friendly: They generally have a lower environmental impact compared to large-scale hydroelectric plants and fossil fuel power generation, as they typically require less alteration of natural waterways and produce no direct emissions.

• Generates enough power to cater the needs of locals: Mini-hydel plants can generate sufficient electricity to meet the needs of local communities, particularly in remote or rural areas where larger power grids are not feasible.

• Avoid transmission losses, if any: By being located close to the end-users, mini-hydel plants reduce the distance that electricity needs to travel, thereby minimizing transmission losses.

All of these aspects contribute to the overall benefits of mini-hydel plants.
