I have a love-hate relationship with the @guardian.
😍
I recently contributed to an impeccably researched series.
😡
Last year they did a hit piece on EVs, again using the material use angle, that cited figures a 1000x too large!
@guardian But what does the REPORT say about electric vehicles??
Uhm. That they are a great replacement for regular cars, although public transit and biking are even better.
100% in line with my message.
But. But.
How can EVs be SO important in the @guardian article then?
Good question.
@guardian But what about the big picture?
Mining IS the big culprit right?
Nope. Wrong again.
About mining the report says:
"mining causes less than 1% or land-related (vs climate change related) biodiversity impacts and of that, coal causes 10x more impact than mining for renewables."
@guardian And here is the entire big picture.
Mining of metals is not the big thing here.
And remember that renewables and electric vehicles require only a very small part of that metal.
If we can use that to replace bio-fuels and and fossil fuels we do the environment a BIG favor!
@guardian Instead (and as the graphs show) the report is mainly about biomass from agriculture and forestry.
Especially food. (Eat less meat!)
And fossil fuels.
Especially coal.
And do you know how often the @guardian article mentions ANY ONE of these words?
ZERO TIMES!
@guardian Instead the article gives the impression that the report is about mining. Especially for electric vehicles and construction. It uses that as a scaffold to go on a rant against decoupling.
I think this is journalistic maleficence dear @guardian.
Please do better.

Renewables also had a role: "tension was very high and sustained, causing the disconnection of generators".
An inside source tells me the voltage went above 110% in many places and solar was required to switch off, which meant 8GW was lost all at once.elpais.com/economia/2025-…
Let's start with some quantifiable facts. (Things this conservative armchair energy philosopher is allergic to.)
First thing we notice is that solar and wind are clearly surpassing nuclear (though the new leadership of the department of energy denies it).
Many people think solar and wind won't be able to keep the grid stable because they lack "inertia".
I think solar, wind and batteries will do a BETTER job and I think you can explain it thus:
- the old grid is a record player
- the new grid a digital player

If you play vinyl records, the rotating mass of the turntable is used to keep the speed steady. This leads some vinyl enthusiasts to seek more mass because that will keep things more steady.
This turntable by Excel audio attaches a separate mass. (Overkill but makes my point.)
In the same way the inertia in the rotors of current power plants helps the grid to keep a steady 50 Hz (in e.g. Europe) or 60 Hz (in e.g. the US) frequency.
These machines turn a heavy copper coil wound around a heavy iron core and this helps keep the grid frequency steady.
The heathen Gods have gathered on mount Olympus for a feast. Sun god Apollo is recognizable by his halo, Bacchus (Dionysus) by the grapes, Neptune (Poseidon) by his trident, Diana (Artemis) by the moon, Venus (Aphrodite) by Cupid.
