And while it might be true of a densely populated and cloudy country like the UK, so what? As long as you can solve long-distance energy transmission from countries that don't have that problem (Spain would come to mind as somewhere close, Northern Africa would be the next option), there's far more energy provided via renewable sources that human kind will be using for some centuries yet (by which time we should finally have fusion licked).
