New record (..that probably won't last long): 80.4% instaneous penetration of RE in the NEM over the weekend. More than half it coming from behind the meter (..rooftop solar) 🔌💡 www.theguardian.com/environment/...
Screen cap from openElectricity showing the generation profile on Sat 19th, where new record for instantenous generation (80.4%) was set around lunch time 

Rooftop solar supplied more than half of load at the time

Fossil fuel lobbyists are flooding social media with ads, outgunning the minimal effort of the renewables industry, which is leaving the work to cash-strapped NGOs.

They disinvented the VCR. You might think that the reason we don't have VCRs anymore is because VCRs were supplanted by DVDs, PVRs and streaming, but that's not the case. They had it in for the VCR from the very start, and they never stopped trying to kill it. Eventually, they succeeded. 1/
A 1960s family living room in which a mom, dad and two kids are mesmerized by a cabinet-style TV. The image has been altered. The TV has an early 1990s VCR atop it. The TV screen is displaying a cross-sectioned human head with brains and spine on display. A huge fist has materialized in the room, with bloody spiked knuckle-dusters, smashing into the VCR. The oil painting over the sofa has been replaced with a pulp image of a male head, its cranium removed and replaced by a dome. Inside the dome is a red eight-segment VCR clock, displaying 12:00. The background in the painting is a tangle of cassette tape. The whole image's colors have been boosted, giving it an overexposed look.

Unlike that of the rest of southeast Asia, Pakistan's gas demand has been falling. Pakistan's solar boom is partly attributable to excellent do-it-yourself videos on Tiktok and youtube, and partly to two other factors, says Zainaab Basil in an interview with BNEF. www.bnef.com/insights/40017
Chart of Pakistan's gas demand, historical and forecast, sourced to BloombergNEF which collated data from Pakistan Energy Yearbook, Pakistan Economic Survey, Bloomberg Terminal’s AHOY JOURNEY (historical), Independent System and Market Operator’s (ISMO) Integrated Generation Capacity Expansion Plan 2025-2035 (IGCEP 2025-2035), National Electricity Power Regulatory authority (NEPRA).

The chart shows gas demand by sector (grid power / domestic / fertilizer / industry / other / losses), in billion cubic meters. Between 2020 and 2025 the total dropped 16%, though it spiked in 2021 on higher losses. The main sectors in the drop were grid power, domestic and industry. This decline is expected to continue at a slower rate to 2035.

To be honest, I worry more about some senior engineers, especially when they want to keep a tight leash, and focus AI on low-value work because they are too precious about delegating any architecture decisions at all.

I used to go with the AI as an over enthusiastic intern metaphor, but it feels different in the last six months. Partly better models and tooling, but also setup for project context and practices. Often shocked at how often it can implement complex features at a higher quality than me...

if you can’t replace your stove, you can get a great little induction hot plate for about $100 mine handles all my pasta, soup, anything that needs boiling or simmering. boils faster than gas, holds a perfect simmer reducing gas use helps even if you can’t quit it

Conventional wisdom says rooftop solar meets **exisiting** electricity demand. What if rooftop solar actually **increases** electricity demand, improving living standards and driving economic growth? This is exactly what our new analysis of Pakistan's solar boom shows. Let's dig in.. 🧵
