Oh hey @ember-energy.org & @mliebreich.bsky.social, love the new report on modernizing Sankey diagrams. What do you think about further subdividing 'Useful Energy' into 'Life Support' and 'Other' (or similar names)? Basically, distinguishing energy that keeps people safe and healthy from other uses.

Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

β€œHelsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

*SO* thrilled yesterday to see the first screening of An Irish Atlantic Rainforest, the film about my 17-year journey rewilding a West Cork farm.

It went far and away beyond my hopes: a mesmerisingly lovely, immersive piece of work, almost dreamlike in parts, but grounded in ecology and daily life.

Street transformation from car space to street willed with people including kids

Street transformation from car space to street willed with people including kids

It’s not just about what you remove (cars, noise, dirty air). It’s about what you add (people walking, a lot of bike parking, trees, outdoor dining, and room for kids to play safely). Amsterdam: 1986 and today.

Streets for people.
