Det er slående, at de 48.600 børn ikke er direkte adresseret i det nye regeringsgrundlag for en regering, som SF deltager i, og som Enhedslisten støtter, skriver Informations Laura Friis Wang.
2/3 of all energy going into the energy system globally goes to waste.
@chrisjardineenergy.bsky.social discusses energy efficiency with @nickeyre.bsky.social.
Energy efficiency is responsible for more decarbonization than renewable energy, and still holds huge potential.

the photoenergetic power conversion efficiency of solar is ~20%; corn is ~1%. (20× less efficient)
an EV takes ~0.15 kWh/km; an ICE car uses ~0.75 kWh/km. (5× less efficient)
"99% less land per mile driven" is not hyperbole. it's a pretty solid estimate for average vehicles and energy systems.

Piketty og 45 forskere: Vi kan skabe en verden i penge- og naturbalance. Vi skal arbejde langt mindre, ikke lave så mange fysiske ting og sager - og de superrige skal beskattes hårdt. Det kræver selvsagt mod - men alternativet er økologisk sammenbrud.

1/ A climate-focused thread 🧵 on the new Danish government programme, listing what I see as key initiatives (and omissions) regarding overall climate policy, mobility and related areas (energy and land use planning).

Engang var opgøret med de laveste ydelser et hovedkrav for venstrefløjen og De Radikale. I dag nøjes en ny centrum-venstre-regering med at begrænse nogle af konsekvenserne
Et internationalt forskerhold med den franske økonom i spidsen har leveret en gennemregnet manual for omstilling til en økonomi med lighed, miljø og menneskelig trivsel i centrum. Den forudsætter opgø...
Farming as a business is now with the Ministry of Business, so on par with other businesses.
And other issues relating to compliance is with relevant ministries (justice, environment,…) - again like other businesses.
Da landbrugsministeriet i sin tid blev oprettet som det første erhvervsministerium, stod landbruget for 90 procent af eksporten. Lidt under halvdelen af befolkningen arbejdede på gårdene.

Put wind or solar on the land that grows ethanol corn. Run electric vehicles off the power. Use 99% less land per mile driven, at far lower cost. Let farmers use the freed-up land to do actual farmer stuff, like growing real food for humans and being good custodians of land for future generations.

Landbrugsministeriet stod som en manifestation af erhvervets politiske magt. Det samme gør lukningen
Desværre er bedre indeklima i folkeskolen ikke blevet prioriteret i regeringsgrundlaget. Det nærmeste jeg kan finde er dette punkt.
"Anlægsmidler prioriteres til at renovere de mest nedslidte folkeskoler og til at skabe bedre rammer for dag-, fritids- og klubtilbud."

“Politicians and business leaders said we had to slow down the push for renewables, but now in the current crisis they complain that our energy costs have jumped, and that is because we rely too much on fossil fuels.”

The new Danish government programme was announced today👇.
I'm still reading the details, but so far I want to credit it for mainstreaming the benefits of the green transition.
An example is that the 85% CO2 reduction target (increased from 82%) is in the section about 'A more prosperous Denmark'.

Also E15 cost savings are an illusion. Yes E15 currently costs less per gallon at the pump but 1) it’s less energy dense so cars don’t go as far per gallon & 2) it’s more corrosive so gas stations would have to upgrade tanks/pumps & would likely pass on costs to consumers, raising prices at the pump
I think it would be wise to formulate an independent policy on data centers, specifying strict demands on energy efficiency, self-sufficiency of some green electricity, ability to act flexibly on the grid, placement of centers for easy grid connection and easy utlilization of waste heat, and so on.
