Exciting to see the range of schools on track - big state schools, small liberal arts colleges, etc.
Roxbury Community College did a big GSHP/solar project in 2016/17. I wonder how much that lowered their Scope 1 emissions?
Are they among the > 600 colleges in your dataset?

My @wellesley.edu students and I are tracking more than 600 clean energy manufacturing projects in North America at The Big Green Machine.
Check out our interactive dashboard and let us know what we are missing, what we’ve got wrong, and what needs updating. 🔌💡

Are the slow downs concentrated in Democratic-led congressional districts? Our tracking says no.
In general, slow downs are following the same pattern as investments in US clean energy manufacturing — meaning they are largely concentrated in Republican-led congressional districts. 🔌💡

For the first time since Trump’s inauguration, projects that have advanced toward production exceed those that have suffered delays, been reduced in size, canceled, or paused across all metrics (number of projects, size of investment, and announced jobs).

Thanks. Good point. Hope we'll learn more about the economics of this and similar projects!

A definite downside for this specific project. But I was trying to look past that small detail and towards all of the other potential applications for decarbonizing industrial heat important to manufacturing the materials needed for renewable energy technologies!

Didn't we try that? theconversation.com/las-long-tro...
LA’s long, troubled history with urban oil drilling is nearing an end after years of health concerns
The Los Angeles area has over 20,000 active, idle or abandoned oil wells. The city and county have voted to ban new ones after studies showed health problems in residents living nearby.
