There is no need to shift energy from summer to winter except in a country far from the equator where all electricity sources except solar would be forbidden by law. In real life, summer production is consumed in summer (or curtailed).

Time for 2025 updates to my annual “opinions about solar” thread. If you like these, you might like the second edition of my book, Solar Power Finance Without The Jargon. A 30% discount code WSQ0437 is valid on publisher website until end of November 2025.

The prices will really depend on much there is flexibility in the system vs how much PV, and on the rate of electrification. It’s not sure at all that prices will be mostly zero during sunny hours in 2030.

Why isn't the medieval siege and intentional starvation of a population on the front pages of every newspaper?

Why isn't every single journalist asking one question to our politicians: what are you doing to stop the starvation of millions of people?

And the ones speaking out are the terrorists?

On doit utiliser les réseaux de façon plus intelligente => faire passer plus de kWh à réseau constant. Donc même si le coût total du réseau augmente fortement, le coût par kWh n'augmente pas autant.
Here the CEO of Total and EDF that agree in 2019 that long distance is no possible with EV's, which can only work in cities, and that "we should speak about hydrogen". youtu.be/18QDlkivfkc?...

@mliebreich.bsky.social if you meet any of those executives who needs a consultant to explain the basics, feel free to give my contact info 😉
Indeed, it reminded me of Pouyané who was confusing amps and volts or Clamadieu who wrote that the French grid was on the brink of collapse. Do oil & gas executives really not understand electricity or they’re just spreading FUD?
Good question, I don’t know of any online course on the topic. I would go through the grid code of interest (RfG - regulation 2016/631 - if it’s for generators in Europe) and use an LLM to ask questions and get clarifications. Or ask LLM to generate a course?
Good point, I didn’t know this. It seems it can be solved with proper control design? Anyways, grid-forming inverters are not prohibited but they if course have to meet the requirements.
Inverters are required to disconnect in case of clear outage but (starting at Type B units) to stay connected in case of short disturbance (LVRT). But that’s for voltage disturbance. In case of *frequency* deviation, I don’t see what negative role a grid-forming inverter could have.
Grid-forming inverters are not prohibited afaik, otherwise can you point to the corresponding part of grid code? In Belgium, DSO’s require an external decoupling relay anyways, so we have disconnection in case of outage whatever the type of inverter.

In his inaugural speech, new Secretary of Energy Chris Wright invoked Germany as a cautionary tale. It will perhaps not surprise you to learn that he said a bunch of dumb, wrong shit.

Il suffit de voir le vocabulaire utilisé par les médias européens. Un civil palestinien qui commet une attaque est un « terroriste », mais ce mot n’est jamais utilisé pour qualifier les colons. Idem pour « otage » vs « prisonnier ».
La Shoah est principalement instrumentalisée politiquement par le lobby pro-israélien.

First of all, discovery. We can't stop finding lithium. In October, USGS shared a 5-19 million ton estimate in Arkansas (Smackover). The US already had the 3rd-largest lithium resources in the world. This new discovery could push us to the top (for now). www.usgs.gov/news/nationa...
