French ground-mounted solar tender prices fell to €60/MWh in October 2026, down from €79.48/MWh in the previous comparable round in 2025, a decline of nearly 25%. Small-scale rooftop PV (100–500 kW) prices also dropped to €75/MWh, down 15.5% from €88.73/MWh in the first tender held in 2025 […]

Historians and political scientists will undoubtedly spend the 2030's discussing a new breed of heads of state described as @ImmatureIndividual

The conversation explores various perspectives on Finnish President Alexander Stubb's approach to international politics, particularly in relation to former U.S. President Donald Trump. Participants in this discussion highlight Stubb's pragmatic and strategic handling of Trump, likening it to managing an immature individual while quietly advancing Finland's interests. There is admiration for Stubb's intelligence and realism, with some commenters noting Finland's robust defense strategy and historical awareness of Russia's aggressive tendencies

Rapid investment in demand flexibility and battery storage is crucial for the financial viability of existing power plants, as spot prices increasingly hover around zero. For the French nuclear fleet the annual 800 hours with negative price are economically equivalent to a drop in capacity […]

Scarce resources induce innovation. During the embargo South Africa developed the Fischer Tropsch process to make gasoline from coal. Fortunately, today there are cleaner technology options to ensure mobility in an oil-constrained economy.

Now that the EU has banned #Greenwashing, Munich's municipal utilities company SWM has replaced their official claim of carbon neutrality by 2040 with more vague statements, like district heating "mostly from deep geothermal" […]

The same lack responsibility is featured in the race to the moon, including US and China. A station on the moon would probably be powered by a nuclear reactor. Scientists say they "can't be bothered" to worry about any nuclear waste on the moon […]

The chanches that Rosenergoatom would spend the estimated 21 billion euros to responsibly decommission and dismantle their 35 ageing nuclear reactors in Russia are probably close to zero. The company’s own estimates point to a funding shortfall of approximately 18.7 billion euros […]

Who else should pay for climate change if not Big Oil?

The new #Mispel law in Germany provides clear pathway for home batteries including bidirectional EV chargers to feed into the grid and avoid double grid charges.

The existing EVs on German roads already have enough battery capacity to cover the entire national electricity demand for two hours […]

Germany has increased the price of the #Deutschlandticket to 66€/month just a few days before reducing gasoline prices.

The ticket allows unlimited rides on all public buses, trams, metros and local/regional trains.

Experts point out that people should be […]

Finland is once more one of the baddies. EU is upset that Finland doesn't allow electricity consumers to share self-generated or stored renewable electricity with other customers “within the same bidding zone or a more limited geographical area,” as the Directive (EU) 2024/1711 mandates […]

Contrary to what the Finnish army has always claimed, research of Lappeenranta University suggests that #WindPower offers better opportunities for surveillance of Finland's border with Russia.

Passive radar equipment on towers can improve detection of low-flying drones despite some interference […]

Helsinki’s new Kaivokatu plan is meant to make the city centre around the Railway station safer by banning through for private cars and giving more space to pedestrians and cyclists. But the national federation of visually impaired has appealed against the plan, saying the open layout, more tram […]

Just used a Volkswagen ID4 with 17.000 km mileage and tires already worn out. As a new set of tires costs 1700€ it seems the cost of tires at 10ct/km is higher than the cost for electricity.

While Google announces three new massive #DataCenters in #Finland with no limits to energy use, their home state is passing laws ensuring that "those profiting from data centers aren’t doing so at our expense."

Data centers must pay for:
-transmission and distribution upgrades and load […]

Another remarkable discovery in the Finnish media is that #BalconySolar is actually safe and making huge progress worldwide.

It feels as if Finns had no idea what is happening outside our borders.

Germany already has millions of #Balkonkraftwerk units in use and Finland still claims this […]

Even the traditionally pro-nuclear Finnish media appears to finally comprehend that nuclear power is prohibitively expensive.

One key phase of the solar age is coming to an end. Germany’s 20-year fixed EEG feed-in tariff, which helped kick-start the global solar boom in the 1990's and set off a downward spiral in panel prices, will end this year. Minister Reiche, a fan of gas and nuclear, appears determined to block […]
