14.) Carbon dioxide, which is recognized as the major
contributor to global warming as a "greenhouse gas," is formed when
fossil fuels are combusted, as in electrical power plants fueled by
coal, oil, or natural gas. One potential way to reduce the amount
of CO2 added to the atmosphere is to store it as a compressed gas
in underground formations. Consider a 1000-megawatt coal-fired
power plant that produces about 7×106 tons of CO2 per
year.
