Coal is a
natural source of energy. But has limitation in earth. Coal is made from based
on carbon. And other metals also contain such as H (hydrogen), S (Sulfur), N
(nitrogen), O(oxygen). Coal is harder than any other metal. Coal mainly found
in Soil, By using coal and give high pressure people can produce high
temperature which is used by people in various ways such as produce
electricity. Coal is largest natural energy in world anthropogenic. By using
coal there have create much amount of CO2 (carbon die oxide) which
more bad for our environment and polluted our air. By using the amount of
pollution is more than using natural gas in produce of electricity. When
produce 1 MH (Mega watt hour) produce electricity carbon die oxide produce
about two thousands pounds by using coal. And when also same amount of
electricity produce by using natural gas carbon die oxide produce one thousand
pounds. For reducing the emission of CO2 in United States more use
natural gas and less use coal.
