Coal Generation G7.

Zoomup
Many old coal mines had their own electrical generators. They were self sufficient and had a good reliable supply for essential equipment like ventilation fans, water pumps, winder winch, lifting gear and coal cutters etc.  In the U.K. in about 1950 colliery generating plants were shut down and the supplies were obtained from the Electricity Boards. This was a bit of a shame really, as unmarketable grades of coal could be used at the colliery generating plants' boilers.


Now Old King Coal is an enemy it appears.

    mmmm afraid it is zoomup , and around 40% of the worlds electricity is from thermal coal , so a few more to close and be decommisioned, some are not very efficient either , only about 10coal plants achieve over 40% conversion of the coals energy into electricity kw theres the nox and sox also .


    Some say: Nitrous oxide is released into the atmosphere through agriculture, when farmers add nitrogen-based fertilizers onto the fields, through the breakdown of animal manure. Approximately 79 percent of all nitrous oxide released in the United States came from nitrogen fertilization.


    Can't waste heat from power stations be recovered and used to grow tomatoes or heat buildings etc?
