Wind power: Even worse than you thought pretty well tells you the story. Wind power in its current incarnation is not a solution to renewable energy needs. The created market in renewables obligation certificates is keeping wind farm operators in business, not the selling of energy.
So it sounds like we need (e.g.) better storage, to deal with the timing issues, a pan-European grid to move energy from where it is windy to where it is needed and some new thinking about renewables.
Oh yes, and another way of expressing consumer preference: I liked Ecotricity for exactly the reason that it tried to invest more of my money in renewables than other energy companies. Sadly it looks like that might have been slightly wasted.
