- Solar energy has consistently been underestimated. Today, it adds more capacity/yr to global grid than any other source in history. If trend continues, solar will deliver more electricity generation/yr than any technology before it. Graph from @nathanielbullard.com - great newsletter
- ‼️ My first official public event in my new role at Oxford: I will host Ernest Akinlola (CEO, Bboxx Nigeria) at @orieloxford.bsky.social 15 May, 5:15PM speaking about unlocking solar power’s potential across Nigeria & Africa. Secure your spot here: www.oriel.ox.ac.uk/events/oriel...
- Denmark’s electric vehicle surge is just incredible. 🚗⚡️ Feb 2025: BEV 66.1%, PHEV 2.8%, ICE 31.1% Trailing 12M: 54.4% BEV ➡️ Only Norway ahead now, Sweden 3rd. ⛔️ ICE extinction event incoming? The internal combustion engine is pretty much over in Scandinavia. @leraffl.bsky.social
- Spain blackout is a wake-up call. Grid resilience & flexibility are essential for reliable energy systems. Bloomberg quotes my post on how batteries now account for >50% of supplies Texas's grid operator uses to ensure stability through ancillary services market. www.bloomberg.com/news/article...
- Almost 40% of global GHG emissions come from hard-to-abate sectors like heavy industry, shipping, & agriculture. Decarbonizing these is a tough challenge for Net Zero. 🏭 But how do we do it? Join me @auroraer.bsky.social Spring Forum in London to discuss.
- The world’s largest electric ferry just launched! 🚢⚡️ A huge leap for green transport—2,000 passengers, 500 vehicles, and zero emissions. Proof that clean tech is making waves in maritime engineering. Read more: www.theengineer.co.uk/content/news...
- AI can boost energy system efficiency—optimising grids, integrating renewables, and enabling smarter demand. But this article from my colleague Felippa Amanta shows, AI’s growth could also drive up energy use through data centres and shifting demand. theconversation.com/ai-is-suppos...
- Decarbonising buildings is crucial for climate goals, but should we prioritise insulation or heat pumps? Where is the right balance? My paper with @samhamels.bsky.social digs into this important question. More here: www.sciencedirect.com/science/arti...
- 🌍 3/4 of world relies on imported fossil fuels. 📉 20% of global GDP (Germany, Japan, Italy) get 2/3 of energy via imports. 🚀 Fossil fuel imports ⬆️ 12x since 1960—now 37% of global energy (2022). 🇨🇳🇮🇳 Even China & India (top producers) still need imports. Speeding up clean energy is critical.
- Reposted by Jan RosenowTesla 🚗 sales plunged in Germany 🇩🇪 (-46%) & UK 🇬🇧 (-62%) in April, per new data 📉, despite the updated Model Y. European sales continue to struggle. Turns out that supporting questionable politicians damages the brand. Who would have thought…? www.marketwatch.com/story/tesla-...
