Question

Mention the advantages of hydro-electric power over thermal power.

Answer 1

1. Renewable Resource: Hydro-electric power relies on water, a renewable resource, whereas thermal power depends on finite fossil fuels (coal, oil, gas).
2. Environmentally Friendly: It produces no direct air pollutants or greenhouse gases, unlike thermal power which emits CO₂, SO₂, and particulate matter.
3. Low Operating Costs: Once a hydroelectric facility is built, it has low maintenance and operational costs compared to thermal power plants.
4. Longer Lifespan: Hydroelectric plants generally have a longer functional life than thermal plants.
5. Energy Storage and Regulation: Hydropower dams can store water, allowing for power generation on demand and better grid stability.
6. Irrigation and Water Supply: Many hydro projects serve multiple purposes electricity, irrigation, and drinking water supply.
7. Reduced Fuel Dependency: Hydropower reduces reliance on imported fossil fuels, enhancing energy security.
