What process occurs when coal is used for energy?
Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
What process occurs when fossil fuel is used for energy?
Energy gained from burning fossil fuels is converted to electricity and heat in commercial power plants. When fossil fuels are burned carbon and hydrogen react with oxygen in air to carbon dioxide (CO2) and water (H2O). During this reaction heat is released which further amplifies the reaction.
Is coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
How do we use fossil fuels in our daily lives?
Fossil fuels are used to produce energy; in the home they are burned to produce heat, in large power stations they are used to produce electricity and they are also used to power engines.
Is coal a good way to generate electricity?
Burning coal is the most cost-effective and energy efficient way of generating electricity.
Is coal the cheapest source of energy?
Of all the fossil-fuel sources, coal is the least expensive for its energy content and is a major factor in the cost of electricity in the United States.
How beneficial is coal to life?
Coal accounts for over 37% of the world’s electricity supply. It is fundamental in powering homes and industry, providing energy for transport and producing steel and concrete.
