🚨 Half of all new cars registered in Ireland in September were fully electric (49.3%)! Car sales here are concentrated in January and July, so a single month is misleading, but I pulled out the BEV sales share for July-September sales for the past years: 2024 - 14% 2025 - 22% 2025 - 35% 📈↗️👆‼️

🚨 Irish solar generation dipped noticeably during the partial solar eclipse earlier this evening, bottoming out at just 8MW. Overlaying today's generation with yesterday's, we see a clear notch around 7pm when the eclipse was at its greatest 🌑 ⚡️ #SolarEclipse #SpeirGorm

6% of the car fleet in Ethiopia is electric, compared to a global average of 4%. It shows what can be done when policies such as tariffs strongly incentivise EVs and disincentivize ICEs. (low-cost electricity thanks to a large dam also helps)

Evidence from Australia shows mandatory helmets & hi-vis will reduce numbers of people cycling. Perversely, this will reduce accidents involving cyclists. But Ireland also has targets and plans to increase active travel! The Government needs to watch out for the law of unintended consequences.
