It took about 25 years — but it is important. The ÖBB line to Italy through Graz and Southern Austria is part of a larger rail expansion. 🚆

Det er Punkt 4 i planen. Jeg har editeret teksten her:

🚢⚡ A new era of green high-speed transport is on its way across the Kattegat!
Molslinjen has ordered two – likely soon three – all-electric mega-catamarans from Incat Tasmania. These vessels, set to enter operation 2027/2028, represent the world’s largest electrification project at sea to date.

When I saw how many biomass-based CHP plants were pre-qualified in the current Danish CCS tendering process before the holiday, I became deeply worried. Why? Because we already use far too much biomass in power plants. Adding CCS further reduces flexibility at a time when we need the opposite.

The Danish government has announced a major cut in the electricity tax – from 72.7 øre/kWh to the EU minimum of just 0.8 øre/kWh in 2026 and 2027.
For households, this means significant savings:
A typical family: ~4,000 DKK less per year
Pensioner couples: ~2,700 DKK less per year

🌞 Solar power helped Europe pass the heatwave “stress test” 🔌
As temperatures rose in Europe at the start of July, so did electricity demand, driven by the growing need for air conditioning. In Spain alone, demand rose by 14% during the heatwave, pushing power prices >€470/MWh in some countries.

The Strait of Hormuz and Danish use of biomass
Denmark’s reliance on 200 PJ of biomass - nearly 30% of national energy use -is not a model to follow. It should be 30–40% lower. If the Strait of Hormuz were to close, oil and gas prices could spike dramatically.
