Electricity is necessary sources in our life.
However,conventional power generation using coal fire definitely produces carbondioxide because of the fuel's combustion during the energy conversion process.
According to the United States Energy Information Administration(U.S.EIA),31,780.36 million metrictons of carbondioxide were emitted from electric power generation in 2010, and it has increased 10% since 2006.
Approximately,half of the global carbondioxide emission was produced by coal [1,2].
