I thought this was fairly well established, but: here's another new study showing that wind and solar complement each other and make for a more stable grid when combined.

I have had the pleasure to work with Lisa Werder Brown and I'm thankful her advocacy and those throughout Pittsburgh working to bring attention to our watersheds. As a Landscape Architect, I'm always a sucker for Frederick Law Olmstead references, too!
In 1910, landscape architect Frederick Law Olmsted Jr. recommended that Pittsburgh turn the Saw Mill floodplain into a park. “By 1939, the entire floodplain was developed,” says Lisa Werder Brown, executive director of the Watersheds of South Pittsburgh. buff.ly/XQ9PHfv
Meet the ambassadors for Pittsburgh’s most flood-prone neighborhoods
Pittsburgh’s flood-prone zones get little support from the state or feds. As climate change drives erratic weather, these local leaders are stepping up.

“As pickups transitioned from farm/ranch workhorses to lifestyle vehicles, their design shifted accordingly: Cabs expanded to accommodate more passengers, while beds shrank. The first generation of F-150s were 36% cab & 64% bed by length. By 2021, the ratio had flipped.

This needs to be done. We speed regulate less dangerous EVs (e-bikes), we should be doing it with these much larger machines.
China is bringing the hammer down on hyper-fast EVs, setting a minimum 5 seconds for accelerating from 0 to 100 KMH (62 MPH).
For context, the Rivian R1S hits 60 MPH in 2.6 seconds, as does the Tesla Cybertruck in "Beast Mode." (H/t @reillybrennan.com)

China plans to require passenger vehicles to default to a state where acceleration from 0 to 100 km/h takes less than five seconds upon each startup.

When you hear someone say we can’t do active or public transportation in the US, just know we are the global outlier - an aberrant society missing something that the rest of the world has already discovered or never forgot
This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social

People want us to hold the line for a reason. This is not a matter of appealing to a base. It’s about people’s lives.

Any “deal” that ends with Dems just getting a pinky promise in return is a mistake.
The American people are suffering because Republicans refuse to stop healthcare costs from skyrocketing. An agreement that doesn’t fix that reality falls massively short.
