Insane new research. Scientists gave asthma patients free electric stoves to replace their gas stoves, then checked to see if symptoms improved. Not only did symptoms improve, ditching gas was *better than medicine.* Details in today's newsletter: www.climatecoloredgoggles.com/p/electric-s...
Researchers used electric stoves to treat asthma. It worked.
The latest evidence that gas is bad for your health.

The very same industries sold methane (aka 'Natural gas') as a "transition fuel" that helps address climate change. And that lie has been adopted by policy makers around the globe.
Oil Firms Knew for Decades of Methane’s Danger to Planet, Documents Suggest (Gift Article)
The companies knew they were releasing more of the greenhouse gas than they publicly reported, according to industry files cited by the Center for Climate Integrity, an activist organization.

Who said offshore wind turbines were bad for sea life? Researchers described the turbine foundations as functioning as sustained reef habitat for marine resources, a role that once belonged only to natural rock formations and purpose-built artificial reefs. www.ecoportal.net/en/divers-we...
Divers went down to check on 69 offshore wind turbines off the coast of Taiwan, and the 86 species they found living in the steel had never been recorded there before
Divers surveying 69 offshore wind turbines off Taiwan found 86 fish species living on the steel foundations — none had ever been recorded there before construction.

Renewables now dominate new power capacity worldwide. In 2005 they were 28% of additions. They passed half in 2012. Since 2019, never below three quarters. Yes, this is capacity not generation. It shows what gets built. That’s the point. Data @irena-official.bsky.social
Great news in Ontario!⚡️ 🔋Battery storage projects won all 640 MW of IESO’s latest capacity contracts, beating out gas at some of the lowest prices in recent procurements. Every project is 50%+ Indigenous-owned. news.ontario.ca/en/release/1...

Mega heat pumps can replace fossil fuels in industry. In 2018 the frontier sat at ~165°C & a few MW. By 2024: 280°C & up to 100 MW. +115°C & a 50x capacity jump in six years. The tech isn't the bottleneck. Policy, grid access & power prices are. More soon, sign up here janrosenow.substack.com

The IEA says global oil demand will drop 420,000 barrels per day in 2026. At the beginning of the year they were expecting around 1 million barrels per day of demand growth this year. Meanwhile, electric vehicles of all types are selling fast and creating more future demand destruction.

Just met an awesome Habs couple here at the Bell Centre who travelled from Halifax, Nova Scotia: Ben & Jill. She has a classic Saku Koivu jersey 🔥
The amount of Quebec license plates I’ve seen heading west to Buffalo is shocking
old enough to remember (bc it really wasn't very long ago at all) when trucking was considered a "hard to abate" industry

Norway sold 12 petrol cars in February 2026. Out of 7,272 new passenger car registrations, 98% were fully electric. Just 67 diesel & 12 petrol cars were registered. Hybrids? Only 66 in total mostly plug ins. More in my new Substack newsletter coming out every 7 days. Sign up here: t.co/In5lBaF2ox

Using 4-hour batteries in sequence (concatenation) provides for longer duration storage. Building out a mix of renewables - wind, solar, hydroelectric, geothermal minimizes the necessary storage because they complement each other. We can shift from fossil fuels or continue fighting over them 🧪🔌💡☀️💨💧🔋
Mark Z. Jacobson@mzjacobson.bsky.social · 4mo agoThese data illustrate how concatenating 4-hour batteries, provides longer-term (in this case, 14 hours) of storage. In other words, 4-h batteries already provide long-duration storage, and the batteries are inexpensive (0.28 cents/kWh-grid-output for 15.8 GW/63.2 GWh of batteries)
This is fascinating, how we passed peak fossil fuel cars already:
Joseph D. Ortiz@earthsciinfo.bsky.social · 4mo agoUpdate: The US Auto industry has retreated from EVs. That strategy will relegate them to the domestic market only or to extinction. The world is shifting to EVs. Global sales of fully internal combustion engine vehicles peaked in 2017. 🧪🔌💡☀️💨💧🔋 Paywalled link: www.bloomberg.com/news/article...
