According to the Environmental Protection Agency, using liquefied coal as a fuel source would produce 119 percent greater greenhouse gas emissions than using petroleumbased fuel. [34] For 1999, the Energy Information Agency estimated that coal plants produced pounds of carbon dioxide per kilowatt hour.

Radiation Facts. Regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.

Despite the trend of a transition to "clean" energy, the coal industry still plays a significant role in the global economy. The constant need for raw materials and energy for production leads to an environmental crisis—an increase in the content of greenhouse gases in the atmosphere, especially in the mining regions. The purpose of this study was to analyze the impact of the carbon ...
