Vi kan ikke bygge os til nok elnet. Fjernvarme, varmelagre, batterier og fleksibelt forbrug skal aflaste nettet. Næste akutplan skal belønne netvenlig drift og fleksibel netadgang. Mine pointer fra Folketingets energipolitiske åbningsdebat: lnkd.in/p/e6iq2rKC

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.

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...

2/2 But if every crisis leads to a weaker carbon signal, Europe risks preserving the fossil vulnerability that made it exposed in the first place. The long-term answer must also be electrification, energy efficiency, domestic renewables, stronger grids and less fossil dependence in industry itself.

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

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%. 👇
