Question 2.
Which fuel is used in thermal power plant? What are the problems associated with this type of power generation?
Answer:
Coal is used as fuel in thermal power plant.
The problems associated with thermal power generation are:
1. Air pollution – due to burning of coal, harmful gases like carbon di oxide, Sulphur oxide and nitrogen oxide is released which pollute the environment.
2. Health problems – soot particles and the harmful gases like carbon dioxide, Sulphur oxide and nitrogen oxide released from burning coal may cause health issues related to respiratory system.
3. Limited resources – coal is a non-renewable source of energy which means that the amount of coal present in earth is limited. Thus, there will be limitations in the usage of coal if not used cautiously and effectively now.
