Re: Interesting idea
Yes, he showed his annual usage bill. It's not hard to be net positive on energy these days. All lighting is LED which uses almost no power. With heat exchangers it's quite easy to use power only to transfer heat from the air or the ground rather than consuming power to create new heat, a much more efficient approach. 1/3 of the power in the UK grid is now renewable so I don't understand why such an intelligent bunch as Reg readers find it so hard to believe renewables work just fine and are sustainable. It's not even like we've used a huge percentage of our land or coast for this. There are solar farms around most towns now, sure, and there are offshore wind farms in conspicuous locations where the infrastructure exists to manage them. The vast majority of the country is untouched though.
