If the increase in electricity demand is met with non-fossil generation, then the gas consumption can be reduced.

A better investment will be draft-proofing, by sealing up cracks and holes, where cold air from the outside can get in.

Those who heat flat pots & pans over open gas flames, could purchase a portable (cheap-ish) induction hob/hotplate.

It's a quick way to replace gas with electricity, and save about half the energy, e.g. for getting water/food heated up to around the boiling point.

It can also reduce NO2 indoors.

Comic. [Person 1 talking to a person with shoulder-length hair and a person with a white hat.] PERSON 1: I would never get an electric vehicle. Sure, they sound great, but what do you do if the battery runs out of charge? [caption] I felt pretty silly when someone finally explained tome that EVs are rechargeable.

Heat pump sales rose 11% in 2025 across 16 European countries, with 2.63 million units sold.

Twelve countries saw growth, largely where subsidy schemes were stabilised and electricity costs addressed.

Policy certainty and energy levies & taxation are proving decisive.

There is still a lot of changes to make, for Denmark to make/harvest more energy than we use.
For crude oil, about half is imported.
ens.dk/media/7774/d...
For 2024 the imported shares was
* 50 % of biomass
* 50 % of oil
* 40 % overall

The transition is underway.

Not dependent, strictly speaking, as the imported amount of electricity could be made at power plants in Denmark, burning methane gas, if the buyers were willing to pay the higher price, or if the interconnectors to surrounding countries went out of service.

More wind+sun power is needed.

In addition, the consumption of 'natural gas' is generally declining in Europe. Some uses were temporarily halted, others are permanent.

Wind and sun pushes out an increasing amount of coal and gas, and replacing old gas/oil furnaces with heat pumps, also gives a *permanent* reduction.

The main culprit was the power sector.

So, the the greater the heat loss, the more powerful the heating source, such as a heat pump or a gas boiler, needs to be.

A big heat loss in itself is not a problem in itself for heat pumps, as they are made in many sizes, from 3 kW to 50 000 kW.

Higher power units costs more. Takes up more space

The level of insulation affects the heat loss.
The amount of heat loss, at the coldest day, determines how powerful the heating system should be.
To maintain a chosen, desired indoor air temperature, heat delivery from the heating system must match the heat loss of the building (and ventilation)

@strategicperspectives.eu put out a nice analysis last week showing how electrification gets us off US gas in 10 years and off all imported gas except for Norway and the UK by 2040.

NΓ₯r 'Green Power Denmark' kalder projektet "banebrydende", troede jeg, at det drejer sig om ny teknik, og vise, at de udtΓ¦nkte lΓΈsningsforslag virker i praksis.

Hmm.
Hvor ser man 2 eller flere HVDC-linjer koblet til et knudepunkt, sammen med en række vindturbiner?
(Eller "multi-terminal HVDC".)

Er der andre HVDC-net (ikke bare linjer), der nΓ₯r at blive sat i drift, fΓΈr EnergiΓΈ Bornholm kan blive bygget?

Er det rigtig forstΓ₯et, at argumenterne for Energi-ΓΈ-projektet med 3 vindfarme og et el-knudepunkt pΓ₯ Bornholm, handler om at lave
* en redundant el-forbindelse til Bornholm
* en ny linje mellem Sjælland og Tyskland
* udvikling og demonstration af et knudepunkt med flere HVDC-linjer
?

Which helps reduce the consumption of 'natural gas' (together with new wind farms and solar PV), which help reduce the need to import methane (when consumption falls faster than the production fades out).

The two right-most columns are 2 parts of one scenario.
The different height of the red boxes are because of "8% line losses".
Transferring electricity through the wires of the power grid, heat them up a bit, giving some losses. It is necessary to generate more in one end, than used in the other.

Slowly the consumption of diesel and petrol will fall in Europe, as businesses and peple slowly turn away from vehicles with combustion engines.

Freight companies sees a lot of cases, where it is cheaper to buy and operate an electric truck compared to a diesel version, over the life of the truck.

US LNG is now roughly a quarter of EU gas imports, so US cold snaps increasingly transmit into EU prices. Jan 2026 saw Europe’s gas surge ~40% above €40/MWh on cold weather, low storage and tight LNG. Volatility remains the baseline. #Energy #LNG

Getting running costs lower than diesel with high probability, is important for freight/transport.
A sound choice for those who can make long term investments, charge at the depot, and perhaps supplement with a solar system at the depot and a 'power purchase agreement' for cheap renewable energy.

πŸš—βš‘ Europe’s electric vehicle market is closing the year strong despite ongoing uncertainty around the European CO2 standards review.

Putin will probably not like it, when the purchase of methane gas (natural gas) goes down in Europe, reducing reliance of imports.

Hope people will realise how well a properly installed heat pump can work.

Are the realistic guesses regarding how much economic setback the influential and rich people in Russia will accept, before the existing mix of protection schemes and corrupt deals becomes unimportant to them?
