What is the primary source of chemical energy in thermal power plants?

Options

  1. AWater
  2. BFossil fuels
  3. CHigh-pressure steam
  4. DGalvanic cells

Correct answer

B. Fossil fuels

Step-by-step solution

Production of electricity by thermal plants is not a very efficient method and is a major source of pollution. In such plants, the chemical energy (heat of combustion) of fossil fuels (coal, gas or oil) is first used for converting water into high pressure steam.
