Question 7.
Explain the difference:
Thermal electricity generation and solar thermal electricity generation.
Answer:
Thermal energy –
1. Coal and nuclear fuel is used to generate electricity.
2. The thermal energy released due to burning of fuel produces steam at very high temperature and pressure. This energy in the steam drives the turbine.
Solar thermal electricity generation:
1. The electricity is generated from solar radiations.
2. Reflectors reflect and concentrate solar radiation on absorbers. The solar energy is converted into heat energy, which is used to drive the turbine and generator hence producing electricity.
