In defence of Wind turbines.
I have 3off Hugh Piggotts design, 12 footers.
Its winter here in rural Normandy France, so its grey, dim, wet, and mud mud every where!, week in week out.
We are only 50 minutes from the coast, so we get reasonable winds that keep us going and keep the batteries alive. No generator here as it defeats our philosophy of sustainable RE.
However, with good panels we still get 10%, approx., from our 8kW of PV installations. So I am re-calculating cost effectiveness on worse case scenario of 10%, so just another 22kW of PV to go until paradise .........
