Britain's Big Green experiment

 Telegraph:

What do we do when the wind does not blow, and the sun does not shine?

...

The arithmetic is obvious. Renewables will displace gas altogether on increasingly frequent occasions and at times overwhelm the grid with excess power, as already occurs in Scotland.

At other times, renewables will leave a huge and sudden gap. What do we do about Dunkelflaute wind droughts that last for days or even weeks, typically in mid-winter when power demand is greatest, and when there is no solar either?

Delft University says these high-pressure weather systems typically range from 50-100 hours. But they can be much longer during freak years. You need strategic back-up for the worst extreme.

The default solution is to continue piping in North Sea gas, or importing LNG, for use in peaker plants exactly as we do today but in diminishing volumes and with rising reliance on carbon capture.
...

In other words, they will have to use fossil fuel backups to an unreliable system.  I am still of the opinion that "climate change" is an overrated phenomenon.  The predictions of global warming have so far not been realized in any meaningful way.

Blocking US oil drilling will backfire on Biden's climate agenda: report

The carbon intensity of U.S. oil and gas drilling, especially offshore production in the Gulf of Mexico, is significantly lower than foreign alternatives, according to an energy industry report released Tuesday morning.

The report — by global consulting firm ICF and commissioned by offshore energy trade group National Ocean Industries Association (NOIA) — concluded that U.S. oil production is 23% less carbon-intensive compared to production outside the U.S. and Canada. And the carbon intensity of drilling in the Gulf of Mexico is 46% lower than the global average.
