the tech is sound and works. a single panel installation will, according to the blurb, save close to 30% on a household's electricity bills . the wind turbine, they are saying 20%(I know, the mythical average household

). what we dont have is the affordability: the same panel costs 9k to buy and have installed. it needs to be pushed by the government making it affordable. the maximum grant available is only 2k, and i probably use about £200 in electricity a year..in other words, itll take me 80-90 years to make my money back if install a panel and turbine.
the governement should help create the demand on something as important as this. Monies from the fuel duties should be put aside specifically to help drive this forwards.increase the grants, and hell, no Income tax for anyone getting this tech installed. as the price falls, people will buy it up..and like everything else, it gets cheaper, and then the better and more efficient tech gets developed.
Look at the difference in a car 20 yrs ago comapared to one today. they still worked, but they werent as efficient
