"Since 2007, the discovery of vast supplies of deep shale gas in the US, along with advanced extraction methods, have created stable supply and predictably low prices for most of the next century. Of the 1,000 gigawatts of generating capacity currently needed to meet national energy demand, 336 are coal-fired. Surprisingly, America has more gas generation capacity – 450 gigawatts – than it does for coal...
"In an instant, this simple change could eliminate three-quarters of America’s coal-burning generators and save a fortune in energy costs"
"To quickly gain further economic and environmental advantages, the larger, newer coal plants that remain in operation should be required to co-fire with natural gas. Many of these plants are already connected to gas pipelines and can easily be adapted to burn gas as 15 to 20 per cent of their fuel. Such co-firing dramatically reduces forced outages and maintenance costs and can be the most cost effective way to reduce CO2 emissions.
"Natural gas comes with its own set of environmental caveats. It is a carbon-based fuel and its extraction from shale, the most significant new source, if not managed carefully, can have serious water, land use and wildlife impacts, especially in the hands of irresponsible producers and lax regulators. But those impacts can be mitigated by careful regulation and are dwarfed by the disaster of coal."
