"Hopelessly uneconomic on any substantial scale, since it requires a conventional power back-up for when the wind stops blowing, forests of wind turbines are rightly regarded in most countries as an environmental monstrosity."

Previous Quote

Nobody can live in society without conventions. The reason why sensible people are as conventional as they can bear to be is that conventionality saves so much time and thought and trouble and social friction of one sort or another that it leaves them much more leisure time for freedom than unconventionality does.

— George Bernard Shaw
