Here in the UK, you can also harm the environment and emit carbon by buying a windmill from the DIY store and sticking it on your roof. People are mostly doing it for the 'cool factor' since they tend not to generate much power at all. I'm going to dub the coming DIY power generation "Cloud Power", remember you heard it here first. You've got that the wrong way round. I already get my power from 'the cloud' rather than generating on premise :)
