HoustonChronicle.com - Reliant uses mining leftovers to power new plant: "Other power producers had used coal waste before, but Reliant's station is on a grander scale. When fully commercial by year's end, the 521-megawatt plant will rank as the largest waste-coal-fired plant in the world."



I'm assuming that appropriate measures are in place to reduce pollution and carbon emissions; if so then this actually looks like good news. However, I'm a bit concerned that the carbon cost may be high.
