Do not assume a wind turbine will run maintenance free forever.
I wonder how much fossil fuel is used making a turbine?

Nothing runs maintenance free for ever and fossil fuels are used in the
manufacture/transport of everything as well.

Will it need planning permission?

Probably, at least one capable of producing any useful power.

I believe solar panels might have a bit more going for them.
If only there were a cheap way of storing some of the heat we have
today.

Heat bank or thermal store, ie a large tank of water heated by what ever
means to 80C.

Might have got cold by February. I believe I did hear somewhere they
were pumping heat into the ground and recovering is later
