Today almost all coal plants are using “pulverized coal” (PC) technology, this technology involves grinding the coal, burning it to make steam, and running the steam through a turbine to generate electricity. There is a latest technology known as Integrated Gasification Combined Cycle (IGCC). It converts coal into gas and that gas runs through a combustion turbine to generate electricity. This process uses the excess heat.
Pulverized coal burning emits enormous quantities of carbon dioxide, nitrogen dioxide, mercury and microscopic particulate matter. Some existing plants and all new plants are having pollution control technology for reducing emissions of some of these pollutants, specifically sulfur dioxide and particulates. Most common methods to control the pollution is using of scrubbers and filters. Scrubbers are having wet limestone slurry for absorbing sulfur when it pass through while filters are collections of large cloth bags that catch particulates as they pass through the cloth. But even then some smaller particulates can pass out the smoke stack into the air.

Every country in the world contribute different amount of heat trapping gases to the atmosphere. The following list of 20 countries for CO2 emissions is compiled by the Energy Information Agency (Department of Energy) that estimates carbon dioxide emissions from all sources of fossil fuel burning and consumption.

Most of people think that coal had became part of past and now America had moved on to most advance, safer and cleaner energy sources. While in reality still coal provides electricity almost to half nation, which is more than any other source of power and statistics shows that coal use in America now had nearly tripled since 1960.

Think City electric car will be able to drive more than 100 miles on a single charge. Top speed is around 73 miles per hour which is pretty decent for an urban car. It is a good compact design and is enough for a small family of two with children.
