UK generating capacity is ~80GW.  The connected site mentions 15kW
turbines.  If you assume a capacity factor of 0.25, which might be
generous as many areas won't be well suited for wind power, that works
out at 10 million turbines by my calculation.  With 50% generation from
wind, maintaining supply is going to be a challenge when a large parts
of the country are becalmed.

Also had pleasant tinkling of Eastern Rosellas - scarce near the CBD -
as accompaniment. ]
