Why do we need coal for energy production and what are its advantages compared to other sources of energy?

Coal is needed for energy production because it is a reliable and abundant source of energy that can be easily stored and transported. Its advantages compared to other sources of energy include its affordability, availability, and ability to provide a consistent supply of electricity. Additionally, coal-fired power plants can be quickly ramped up or down to meet changing energy demands. However, coal also has disadvantages, such as its negative environmental impact due to greenhouse gas emissions and air pollution.
