Very interesting. I'm not sure a 20-fold increase is on the cards in the foreseeable future, at the moment a major "headwind" (ha ha) seems to be the consenting process which can take years.
Still, UK Renewables says that "The total pipeline of UK wind projects which are either operational, under construction, consented, in the planning system or at an early stage of development now extends to 129GW. (93.3GW offshore and 36GW onshore)." That's versus about 25GW operational right now, so that would be a four-fold increase which would take wind power alone to the same scale as the whole of the UK's current generating capacity from all technologies - although that total will have to rise with the switch to electricity for home heating and EVs: total needs are estimated to be about 200GW by 2040.
To me, it highlights how, while a bunch of people have been bleating on about how pointlessly impracticable it would be to switch to wind power for the bulk of our electricity needs, the wind energy industry has just quietly got on with doing it.
