Been checking out http://www.gridwatch.templar.co.uk/ every day this week, and several days, wind was the largest UK generating source. Nuclear comes in a poor third, and coal virtually unused.

Gridwatch Templar only includes those sites that supply real time generation. There is considerably more wind generation which either does not update its generation so regularly or simply does not show on the grid demand as it is 'behind the meter' (generated power is used by the owner of the turbine(s)). The total wind generation estimate is shown on some other sites (but I, too, keep an eye on the gridwatch site).

There have been several 'home' turbines supplied over the years. Most were simply 'chocolate teapots' in that they never ever recouped the cost (even our ex-prime minister had one fitted (in a wave of publicity, of course) but it was quietly removed some time later).

There are small turbines made specifically for boats and for charging electric fencer batteries, but the turbulence around most dwellings spoils the output. There may be issues with third party insurance – especially if towers and rotating aerofoils are concerned). Have a look at the Navitron.org.uk site for advice or information.

there is a comment column in the April 2019 IET E+P about the problem of restarting a network with significant windpower component in the absence of a large enough base load component eg thought that in case of significant collapse caused eg by sub station or overhead line faults failure then it could take up to 5 days to reconnect all of Scotland from ‘black’ ie a dead network (London may well have same timescales)
