Germany's monthly share of electricity generation from gas hit a ten-year high in November 2025,
at 30.1% of electricity generated.

The gas share stayed below 20% for most of the last ten years, before climbing in 2025.

Grangemouth is the last UK plant making ethylene,
which feeds into the UK Ethylene Pipeline System,
and is then used to make a wide range of plastics

The £120m bailout keeps the Grangemouth plant going.

There's an enormous north-south divide in the curtailment of wind power in the UK.

Northern Scotland had 37% (about 4 TWh) of its wind power curtailed in 1H 2025, at a cost of over £116 m, enough to power all Scottish domestic electricity demand over that six-month period.

Octopus Case Study on regional pricing.

Two case studies:

 • locating a large new electrolyser for hydrogen production, with flexible demand, in Peterhead in Scotland rather than on the Isle of Grain.

Adjusted for the difference in price level, GDP per capita has grown 70% in the US since 1990 vs. 63% in the EU27

This corresponds to an annual growth rate of 1.6% in the US vs. 1.5% in the EU.

The US has been doing better post-Covid, but over the medium run no big divergence

Curtailment of wind:

On Dec. 10th, 97,830 MWh (=4.1 GW av.) of UK wind energy was curtailed, because the grid couldn't carry it.

Wind farms were paid £4,026,927 to *not* generate that energy,
and £9,319,760 was spent to buy that energy elsewhere.
