- Made it back to London and to find the tube line I usually get is suspended due to an earlier power failure. Get off at a different station to walk. Torrential downpour ensues. One of those days ⛈️
- The anti-immigrant crap coming from Starmer and the government is risible, politically illiterate garbage. @pmdfoster.bsky.social’s take here is spot on.
- Battery costs just keep on falling. Great to see them continuing to follow the rapid cost declines we have already seen in solar/wind. 🔌💡
- Good morning with good news: Average price of lithium ion battery packs plunged to $115 USD/kWh in 2024, a 20% cost reduction from 2023. and down 84% from a decade ago. So, battery deployment skyrocketed 67%/year over the last decade to 69 GW in 2024. #energysky ember-energy.org/app/uploads/...
- Walked home via Coruscant this evening.
- There is 4GW of solar proposed in Lincolnshire. Majority has already been granted planning permission. 75% is also from large projects where permitting is decided nationally, not locally. Same goes for grid pylons (eg on the new Grimsby-Walpole line). So, more like "we will fight and mostly lose".
- Nice to see! 🔌💡
- NEW Solar panels to be mandated on vast majority of new homes in England Currently about 40% of new builds have solar; new rules should push that to about 99% Story 👇 www.thetimes.com/uk/environme...
- I fear the UK is using up its strategic sunshine reserve for the year. There'll be none left for summer. (and yes this is a country that busts out the live news coverage when the weather is "abnormally nice")
- Last day to apply!
- New report out today on the costs of different transmission technologies. I find the question of undergrounding comes up a lot lately given concerns about grid expansion or wildfire risks. Glad to see my stock answer that undergrounding onshore lines costs 4-5x per km is about right. 🔌💡
