Advantages and Disadvantages of Coal Energy -

Also, coal energy is independent of climatic conditions. Scalable: The electric power that can be obtained from the coal energy can be easily scalable. That means that we can have 20 MW or 20,000 MW coal power plant for electricity generation. Also, due to the higher calorific value of the coal, it easily burns producing more coal energy.
