Denmark and Minnesota - both ~6m people - share strong agriculture, industry and green-energy ambitions. Thank you @governorwalz.mn.gov and First Lady Gwen Walz for tonight’s reception, and Comissioner Matt Varilek, Ambassador Ken Howery and director Gregg Mast for good talks.

A decarbonised EU27 energy system is not just about replacing fuels. Heat Roadmap Europe 5 shows primary energy supply can fall 39%/~9 PWh in 2050 through energy efficiency, electrification, redesigned heat markets + use of renewable and waste heat. Link: vbn.aau.dk/ws/portalfil...

Stor korrektion i AF26: Energistyrelsen halverer fremskrivningen for datacentres elforbrug. AF25: 36 TWh i 2050 AF26: 15 TWh HRE5: 10–15 TWh Langt mere realistisk – og vigtigt for både elnet, VE-udbygning og udnyttelse af overskudsvarme.

Europe heads into winter with renewed gas risk: storage is only ~65% full, the lowest for this time in 13 years, while gas prices are at a 3½-year high. A mild, windy winter would help. A cold, low-wind winter could quickly tighten markets again. Renewables matter.

An economic catastrophe! The closure of the sugar factory in Nakskov highlights a fundamental problem with investing billions in gas infrastructure where demands could instead be electrified. But first of all its a disaster for many Nakskov families who rely on the jobs.

The New Danish government wants fast oil/gas boiler exit by 2035. It's energy security, electrification, infrastructure + consumer protection. Better municipal heat plans Support: -gas homes waiting for district heating -vulnerable households District heat expansion Potential state heat transmission

Brian Vad Mathiesen @brianvad.bsky.social · 02/06/2026

The New Danish Government's grid focuses • Better use of existing capacity • Targeted expansion of transmission/distribution • Co-location of renewable energy and energy-intensive consumption • Regulation supporting storage and flexible demand • Faster approval • Lower costs

1/4 The new Danish Government presents a new foundation for the energy transition. Energy is still at the centre of Danish politics - now also as security policy, competitiveness policy, infrastructure policy, industrial policy and cost-of-living policy.

Action is making a difference. But not nearly enough. The old worst-case climate scenario (8.5 C) has been pushed out of the CMIP7 because it is less plausible. Why? wind + solar expanded rapidly EVs helped slow growth coal expansion less plausible www.thenewdaily.com.au/opinion/2026...

1/5 Europe is finally starting to align one of the hardest parts of the hydrogen story: support, demand and infrastructure. Germany’s €1.3 billion support for renewable hydrogen production in Denmark is therefore not just another subsidy - its new market design - inovation market design.

Vi har brug for en kulturforandring i vores opfattelse af elnettet. Fremtidens elsystem kan ikke drives med gårsdagens logik. Det største problem i elnetdebatten lige nu er ikke kun mangel på kobber. Det er mangel på fleksibilitet i måden, vi tænker adgang til nettet på. 👇🏼

1/2 An interesting graph - but also one that can be misread. It makes many people think the answer is simply to copy Norway or Sweden in the electrification pathway. I do not think that is the right lesson. Do not copy Norway and Sweden one-to-one.

Solar is no longer just “the future”. In 2025 it overtook wind globally and moved to within touching distance of nuclear. The big question now is no longer whether solar is central to the power system, but whether grids, storage, flexibility and electrification can keep up. ⚡️ @ember-energy.org

Forty years ago, Chernobyl became one of my first real TV memories. I was a child then - about the same age as my own children are now. I remember the reactor, the radioactive cloud over Scandinavia, and the feeling that something very far away had suddenly become very close. 1/4

A positive and timely discussion with Dan Jørgensen on Europe’s energy future. The new EU direction is encouraging: short-term relief and long-term structural change must go hand in hand. Structural change now needs to start with electricity grid tariffs. @ec.europa.eu 1/4

EU’s energy problem is bigger than one fuel, one route, or one crisis. Since 1973 several shocks has hit. And the dependency has changed from Soviet to Russia to now the middle East and North America. The structural issue is import dependency. In 2025, the EU’s energy import dependency was ~60%. 👇

Brian Vad Mathiesen @brianvad.bsky.social · 04/04/2026

Europe’s energy warning has just become more serious. Over the past 48 hours, @ec.europa.eu Energy Commissioner Dan Jørgensen has warned that Europe must prepare for a “long-lasting” energy shock in the @financialtimes.com. This is why EU is considering and preparing for all options. 👇

Brian Vad Mathiesen @brianvad.bsky.social · 04/04/2026

A clear electrification strategy is needed for Europe - focusing on 1) better use of existing grids 2) more renewable energy close to large demands 3) grid expansion and connections 4) focused policies for each electrified industry type and mode of transport - mining ex. below:

Danmark går næppe mod bilfrie søndage eller akutte restriktioner lige nu. Men det ville være en fejl at tro, at vi derfor kan tage let på energikrisen. Danmark står stærkere end mange andre lande, fordi vi ikke er ensidigt afhængige af olie eller naturgas. 👇
