I do not know that there can be too much dependency on windpower. Can there be? I thought you said the problem was with storage, which they are trying to overcome at the moment.
I know what happens when there is a surge. It happened on my estate last weekend. They are still trying to fix some of the houses. Some of the street lights are still off.
Fortunately my son and his family were not affected, so we just stuck a mesage on the window telling them to phone when we were needed. Lost a bit of food from fridge and freezer, even though we were going back and forward with food most weekend.
However, it was to do with old wiring in the exchange, the neutral going, which caused the surge. Lots of computers, lights and televisions blowing up.
I think we will all be more careful in future.
I use Ecotricity because of the agenda. I think most people who use Ecotricity must know of it. He advertises on the back of the Viva! magazine and gives a £60 donation to Viva! for everyone who joins.
Like I said, I can't afford to have solar or ground source, so I think paying Ecotricity to research into renewable energy is one bit towards the environment.
In the advert he says
"Together with Energy and Transport, Food is one of the three biggest sources of carbon emmissions in Britain - that's why campaigning for a plant-based diet is an important part of our work."
Can't be more open than that.
