Fossil fuels are excellent sources of energy for out transportation needs; however they are also the primary source of electrical energy in the world today. Coal power plants account for at least 60% of our national energy and 52% of the world's demand. We, as a world, burn approximately 1.9 billion tons of coal a year to generate electricity. // //How we get electrical energy from coal is by means of coal power plants. These power plants first combust the coal in large furnaces creating tremendous amounts of heat. This heat is used to evaporate water in boilers so they convert to steam. The steam expands, causing pressure to increase in the boiler. A steam turbine is placed at the exit of the boiler where it converts energy from the moving steam into mechanical energy. The rotation of this turbine is used to spin a magnet inside a power generator. This generator is a large electromagnet that encases the spinning magnet. Instead of putting electricity into the electromagnet to cause the coil to magnetize, electrons are captured from the spinning magnet and collected. The electrons are then sent to the national power grid where they are distributed as needed.//
