I think she's doing those things (i.e.: more nuclear, more North Sea drilling, more wind farms), too. She's in the camp of "all of the above".
The last two years have proved that to have a robust energy system we need multiple sources. When you commented this morning that the reason for high natural gas prices was the Russian invasion I (once again) thought, people forget that NG prices in Europe and Asia (and by extension, to a muted extent, in North America via LNG arbitrage) were painfully high last fall. That was 5 months prior to the invasion. They were high because of an unusually long period of calm winds on the continnt drastically reducing wind output over several months.
My view is we need to avoid having all our energy chickens in one or two baskets.
