Coal is a type of fuel which produces a lot of pollution, both in terms of carbon dioxide, which contributes to global warming, and nitrogen and sulfur oxides, which contribute to acid rain. Various other impurities in coal produce other, lesser forms of pollution.
These three Rs each help us reduce our use of energy. Energy (electricity) is usually generated by burning fossil fuels (coal, oil and natural gas), which is causing global warming.
Coal is used as a heating fuel, and to generate steam for electrical power plants. About 45% of the electricity in the US comes from coal. Coal (converted to coke) is a necessary ingredient in making steel.
Production of electricity is the main use of coal in the United States.
90%
We can use more electricity.
It is burned in coal-fired power plants to supply energy.
we should minimize the use of fossil fuels and we should use carpools as well as as drive at a moderate speed. we should try to reduce the use of these fossil fuels that might help us in our future & we should use these fossil fuels carefully.
an energy source
As of 2011, about 42 percent of electricity in the US was derived from coal. There is a push in the 21st century to use other methods of electricity since coal is harmful to the environment.
add it and substact it
Coal production statistics from the US Department of Energy indicate that in 2007, the US produced (and presumably burned) 1.146 billion tons of coal. China produces and burns slightly more.
By increasing the use of solar energy, we can reduce the use of oil, gas, and/or coal, thereby reducing the production and release of carbon dioxide and carbon monoxide into the atmosphere. That could help us to become carbon neutral.
