The energy stored in oil and coal is stored as chemical energy. This energy is released when the substances are burned or oxidized.
thermal power plants are set up near the coal and oil fields because coal and oil are its basic source of energy plus to lessen the cost of production.
Coal is used when a company wants to produce a huge amount of heat energy for the lowest cost, such as for an electrical power plant. Coal is considerably cheaper than oil or gas.
Chemical energy.

Approximately 1,800 pounds of coal yield the same amount of energy as one barrel of oil. This is because coal has a lower energy density compared to oil, requiring a larger quantity of coal to produce the same amount of energy.
By burning them
No, coal is not an alternative energy source. "Alternative" energy sources means energy sources other than fossil fuels (coal, oil, and natural gas).
