Cleanest of all coal-based electric power technologies, gasification has significantly lower levels of air emissions (including volatile mercury), solid wastes, and wastewater.Due to its high efficiencies, gasification also uses less coal to produce the same amount of energy, resulting in lower ...
While carbon capture and storage (CCS) technically does work, it is expensive to build new infrastructure and retrofit old plants. There are other dangers associated with burning coal, too. For decades now, clean coal has been a political pipe dream. It’s the idea that coal—our oldest,...
It used to be called stinky town, because the pollution from burning dirty coal was so appalling. But now, if a new pilot plant works, Spremberg, in eastern Germany, could become the birthplace of a clean-coal revolution. Earlier this month, the world’s

How does clean electricity work? Clean energy is generated through processes that do not pollute the environment and, therefore, do not contribute to climate change. Clean energy also tends to be renewable, meaning it is more resourceful and abundant than more common energy sources, such as coal...
The 2.2 billion gallons of water it uses for cooling is raised 16 degrees F on average before being discharged into a lake or river. By warming the water year-round it changes the habitat of that body of water. Coal mining creates tons of hazardous and acidic waste which can contaminate ...
Clean energy is essential to combating climate change and achieving a sustainable future. But what exactly does it mean? Is clean energy the same as renewable or green energy?
It's vital the community's long-term need for drinking water is placed before the short-term profits of the mining companiesMoore
Hydrogen blending could be set up in clusters, with a high concentration of natural gas power plants (such as in the Houston Ship Channel), and fuel switching could be used for select plants that have high-carbon intensity. Coal plants scheduled for phase-out retrofit could also ...
The amount of solar radiation falling on the Earth’s surface is equivalent to 116 trillion tons of standard coal per year or 6500 times the world’s total consumption of primary energy in 2013 (18.19 billion tons of standard coal). SeeFig. 1.21for the global distribution of solar resources...
