I'm in similar mind to Akenaton on this one. Wind power generates clean energy. I don't tend to sympathise with those who say "not in my backyard". Windfarms CAN supply a small proportion of the power required by Scotland, both for industry and domestic use. But in order to have a truly significant effect on the grid, Scotland---or any other country---would literally have to be covered in windmills!
Just listen for the anti-windmill propaganda from the fossil fuel lobby;there is NONE! They know full well that wind power will never be a threat to their muck -producing industry. Solar power is in the same category. Good for boiling the odd kettle or even shower or dishwashing ---but industry?---Not a hope! There is one clean power generator which terrifies the oil/coal/nuke mob, and that is Hydro-power. Not only the power generated by dams, although there is very significant power from just that source. The real inexhaustible and dependable source of power lies in the oceans. There is power inherent in the waves, in the tides and in the ocean currents. Comparison of the relative efficiencies of wind [gaseous] -driven machines and water [liquid]-driven ones is simple, and you don't need an engineering degree to understand that water, volume for volume and velocity for velocity, has many magnitudes more mechanical power than air. The power potential in global waters--rivers and oceans-- is practically limitless. Governments have been challenged more than once by people [and companies involved in research] who have designed generators for oceanic application, to pit any form of power generation against their design. I know of at least one administration who took up the challenge [avoiding publicity in the matter----] . For some strange reason, the whole discussion faded into oblivion. It's my guess that they got quite a fright when they realised the implications for their oil industry. It's so damned easy to put inventions "on the shelf". Money talks---and pollution still pays.
