In August 2012, coal produced 39% of US electricity, up from a low of 32% in April 2012, when the natural gas share of generation equaled that of coal. The August coal share of generation is still notably lower than the 50% annual average over the 1990-2010 period. Other plants use PRB coal transported by rail.

The products can be reused as green energy products such as bio-coal, biogas (e.g.,
Environmental groups in Germany seem to really care about the usage of water near Tesla’s Giga Berlin, and are especially concerned with how much water Tesla will use. Let’s hope they have that same energy for the LEAG coal mine, which uses more water than Tesla needs for Giga Berlin.
Borla will combine this with its diesel exhaust technology to create a low-cost, novel system that doubles as a device to extract potable water from diesel and other internal combustion exhaust. The heat recovered could serve to preheat boiler feed water, thus providing an energy savings.
