Maintaining a Sustainable Energy Mix

This article deals with the present energy mix and tries to discover how the future energy mix should look in order to be sustainable and significantly reduce environmental impact, for example reduced CO2 emissions. It should be less dependent on the fossil fuels, have increased reliability, have fuel cost with reduced price fluctuations and be able to successfully meet the future demand for energy that just gets larger and larger as world energy requirements increase with the new lifestyle choices.

Coal Ash Safety Issues

In December 2008, the 84-acre coal ash surface impoundment at the Tennessee Valley Authority's (TVA) Kingston coal-fired power plant failed and released over a billion gallons of coal combustion waste.
