Look at Fullychargedshow on Youtube, where Robert Llewellyn has his series on electric cars, electric houses and such. While he may be an actor, he does have a reasonable idea about things, and more importantly, data to back a lot of it up. He does have solar power in his UK house as well, and has the power figures up as well. As well you do get the odd reference to Red Dwarf as well, though he does not wear the costume on the channel much, but you do meet the cast, plus he has done some really good carpool episodes.
Yes I bought the series.........
