Coal fired power plants vs NG. (both require elaborate emmissions monitors)
Coal is a major cause of carbon dioxide

A recent article in the conservative magazine, The Economist , bluntly stated, "Coal is the dirtiest of fossil fuels, producing twice the carbon dioxide that natural gas does when it is burned. That makes it a big cause of global warming." However, coal is cheap, costing between $1 and $2 per a million BTU's (MMBtu) compared to $6 and $12 per MMBtu for oil and natural gas. Approximately 40 percent of the world's electricity comes from coal.

The biggest user of coal to generate electricity is China . Eighty percent of China's electricity is from coal. The country is increasing its coal use at a rapid rate. In 2000 its coal output was 1.3 billion tons, and in 2005 it was 2.23 billion tons. The new coal plants China built in 2006 added about 500 million tons of carbon to its annual emissions.

The U.S. is the second largest user of coal generated electricity. Half of its electricity is from coal power plants. The country's power plants have over 300 gigawatts of capacity. The U.S. emits almost two billion tons of carbon from coal power plants, which accounts for 27 percent of all its GHG emissions, and is projected to increase by a third by 2025. Only twelve coal power plants have been built since 1990. Most coal power plants were built from 1970 to 1989. The bad news is that the U.S. has coal reserves that could last over 250 years at the current consumption rate, but could last as much as 500 years with improved technologies.

In the fast developing country of India, there is an increase in coal output. In 2000, its output was 360 million tons and increased to 460 million tons by 2005. Sixty-eight percent of its carbon emissions are from coal.

In Europe, even more mature economies still use large amounts of coal. Almost half of Germany's electricity comes from coal plants. Germany plans to built 14 coal plants by 2012 with a total of 14,000 megawatts of capacity. Germany is the top photovoltaic (PV) installer, and the second largest user of wind power.
