Arnt you fer getting something
Lantern10 ?
A coal fired power station dont need any other power source to back it up so if yer were to 'cost' it, thats all.
On the other hand, solar or wind power needs a coal fired, or equivalent, back up running at all times, and not very efficiently as a back up, to ensure we actualy have power when we need it. There is allso the the cost of the extra power lines to factor in.
So tell us
Lantern10, are these extra 'costs' factored into that $127 per house..
