"Our local DNO is putting in upgraded cabling all over the place, sometimes is seems that every road around Stroud has got Western Power contractors working on it."

Exactly. The environmental impact is huge. All the cables are metals which have to be mined. All the energy used is being used now, that is diesel etc. Non green elec, everything is now. Doesn't that need to be environmentally cost accounted for? There was nothing in my statement to imply we couldn't cope with extra elec supply, my point was about how we achieve that.
