I've just changed our energy supplier. Faced with the price rises and unbelievable fat cat bonuses of British Gas it seemed the right thing to do. I've been planning to move to an ethical, non-fossil fuel burning supplier for a while, and weighing up the pros and cons of moving to Good Energy against the newly inflated British Gas there didn't seem to be much of a difference at all. It's made easier by the fact that we only have electricity.
With Good Energy it is just over 4p a kWh in the night (we have economy 7) compared to British Gas's 3p (admittedly a whole penny more), but when you see that the daytime cost of Good Energy is only nearing 11p per kWh compared to the 22p of British Gas, it became clear that it was a no-brainer. There's a slightly higher standing charge I think, but considering Katie works at home all day on multiple computers, charging IT goods, and using the cooker etc, the day rate usage should counter any extra cost.
Anyway, it seems to make sense for us. When I can get solar panels on my roof or a water wheel that utilises the stream that might one day run at the bottom of my garden I will. But for now using other people's wind turbines will do.
