Wind Turbines

[NorthernRaider]

Dev most users are simply going the belt and braces approach I think, by using both solar and wind they double up their chances of a reliable back up energy source. once the sun goes down the PV panels stop working, but if there is a bit of a breeze overnight the VAWT will keep topping up your batteries for the breakfast time peak demand. From what I can find out folks like the British Geological people use them as do many boat users, coast guards, remote youth hostels etc. And some folks have cottoned onto to the fact that a lot of modern houses that only have a gap of about 4 foot tween them and their neighbours find it creates a bit of a venturi effect and it creates a bit of a useful breeze...... so they harvest it. Obviously in the UK the further north you get the less sunshine you get over the year, but it also tends to be windier as compensation.
