Scientist exposes anti-wind groups as oil-funded, now they want to silence him

Wind is only useful up to a point, once it gets above 20% of generation capacity ensuing grid stability becomes expensive either through huge price swings or grid level energy storage.

Sure you need baseload/storage as part of the mix - however where do you get the 20% figure from?

For the past year in the UK the average is ~30% generation from wind. https://grid.iamkate.com/

So seems it's possible. Swings in generation are dealt with via inter-country interconnects, pumped storage and gas turbine generation. Nuclear adds a steady base.
