Use of Non-conventional sources of Energy: India, as you know, is hugely dependent on thermal & hydro power plants to meet its power needs. Both of these have adverse environmental impacts. Thermal power plants emit large quantities of carbon dioxide, which is a greenhouse gas. It also produces fly ash which, if not used properly, can cause pollution of water bodies, land, and other components of the environment. Wind power & solar rays are good examples of non-conventional but cleaner & greener energy sources. They are not yet explored on a large scale due to a lack of technological devices.
Thermal power plant uses ________ to produce thermal energy:
Coal
The correct answer is Coal.
- Most thermal power plants burn coal to generate steam, which drives turbines to produce electricity.
- Coal is a fossil fuel that is widely used but contributes to air pollution and greenhouse gas emissions.
- Other fuels like crude oil and natural gas are also used in some thermal power plants.
