Now our car is getting old, and petrol is not getting any cheaper. And both Subaru and Mitsubishi are talking about producing electric passenger cars in 3 years or so.
It occurs to me that getting an electric vehicle at some point would be a good way of soaking up the excess juice, assuming there is any. And if there weren't enough, the area where our house is to be is known as a windy area.

So the questions are, is the wind strong enough to merit a wind turbine, and which one to get?
