i think its from the energy stored by plants that lived hundreds of millions of years ago.=]
The primary consumers of coal would be energy companies burning it to create energy.
the energy that is released when coal was at one time sunlight energy shining on plants.
Its Cheaper to burn and create energy.
Coal.
We burn it to gain the energy we can then use to create electricity.
By burning the coal. The stored chemical eneregy is converted to heat energy. That may be used to create steam. Expanding steam pushes a piston or turbine, converting the heat energy to mechanical energy.
Coal energy comes from the sun. The coal is fossilized vegetation that grew in the sunshine eons ago. The vegetation took up the solar energy using photosynthesis and chlorophyll to produce green matter
From the sun's radiation which made the plants grow that converted into coal
the heat from the burning coal heats water which rises through a tube making a current and turning turbines
burning coal to create steam in power plants
Coal energy is energy derived from the burning of coal. Coal is essentially fossilized carbon.
Coal is less expensive than oil and will be more plentiful in years to come
