Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.
Today, building a fence with solar can be cheaper than using wood.

By September 2025, the EU must submit its new NDC (Nationally Determined Contribution) for 2035.
The dilemmas are clear:
- Can the EU credibly deliver its 2030 –55% target when several Member States are already struggling? I do think we can come on track with cost-effective known technologies.

The new "Norgespris" of 40 øre/kwh is so low, it is hard to understand. This will not bring competitiveness to Europe. This will only reduce incentives for market reform in Germany and not give the hourly price signal needed to handle fluctuations and natural constraints.

Renewable energy + electrification are cheaper than fossil fuels. Nonetheless @exxonmobil continues to push for less focus on Climate policies. When renewables + electrification is cheaper Exxons is also pushing for reliance on expensive energy supply + lower security of supply!
ExxonMobil’s latest moves look like delay dressed up as progress.
Still prioritising oil/gas capex, leaning on CCS/offsets, claiming “demand” is fixed, and avoiding accountability.
Nothing new here as the company has been accused of burying climate science and funding misinformation.

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

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.
