US Wind Energy Just Hit a Major Milestone (cnn.com) 74
The United States set a major renewable energy milestone last Tuesday: wind power was the second-highest source of electricity for the first time since the Energy Information Administration began gathering the data. From a report: As E&E reporter Ben Storrow noted and the EIA confirmed, wind turbines last Tuesday generated over 2,000 gigawatt-hours of electricity, edging out electricity generated by nuclear and coal (but still trailing behind natural gas). Last year, wind was the fourth-largest electricity source behind natural gas, coal, and nuclear, generating close to 380 terawatt-hours for the entire year, according to the EIA. For context, a terawatt is a thousand times bigger than a gigawatt.
Major milestone aside, wind energy in the US is still lagging behind one European country that recently broke a record of its own: Germany. Although the US has more wind capacity by sheer numbers -- it's a larger country with a larger population -- Germany is outpacing the US in terms of how much electricity it gets from wind. In February alone, windmills in Germany generated a record 20.6 terawatt-hours of wind energy, Rystad Energy reported Tuesday, which made up 45% of its total energy in February. In 2020 -- the most recent year the EIA has robust statistics for -- Germany got 24% of its electricity from wind, compared to 8% in the US.

Intermittency matters. Its not clear that what is being reported is what matters. The question is not how much electricity the installed base can generate in a day. And this is not an accurate measure of how much oil, coal or gas it saves.
The problem with wind is that you cannot match generation to demand. And that you have to have standby to cover for it in calm periods.
So to get an accurate assessment, first compare the pattern of wind generation to demand, and strike out any generation that was in pe

You can actually download electricity generation data for the lower 48 states in the UK, split by energy source. Wind generated an average of 1,100GWh per day, with a minimum of 310 and a maximum of 2,000 (in the 365 day period ending 7 April 2022).
How the hell he reckons that you can create "baseload" out of that without storage is a mystery. Essentially, on a day to day basis, wind generation in the US can drop to 30% of its average generation. Without storage (or massive overbuild) that is not possible or realistic.

I am sure you could overbuild enough to always have a consistent supply, but it makes renewables more expensive, and not cheaper. Basically it means you need 3 times as much of wind than of alternative non-renewable / constant or dispatch-able power.
You would also need to either build a grid that can handle that much more capacity (i.e. up to 6 times the demand), or waster the excess energy generated.

The current low cost of fossil fuel backup is deceiving. As age requires more replacement the replacements won't be paid off with the previous normal of high utilization. Also everything on the chain to supplying them is running at much lower volumes or in case of the actual storage, lower utilization. So the cost will increase quite a bit compared to the current cost per Watt of backup and Wh of storage for fossil fuel.
