@costasamaras.com as someone that doesnt understand the intricacies, help me understand how this doesnt advantage the entrenched fossil sector. In my experience, loosened laws tend to tend to give the incumbent the upper hand, no?

Today, I'm proud to announce that we formalized the PJM Governors’ Collaborative - a multi-state, bipartisan organization designed to hold PJM accountable. We are working together to reduce costs for working families and strengthen grid reliability.

The "bike highway S" between York and Lancaster was kind of a joke. Wide shoulders but plenty of pinches and lots of traffic. Lovely bridge over the Susquehanna river. Time to head West.

Obama presidential center has 160 at 500 ft deep. Its not the # or depth, its the heating load (tons or btu). (That sounded a bit dirty but you get the gist) Loyolas School of Env. Sustainability has 91 at 500' or about 450 tons (built in 2013)

i saw an employee from Gethsemane out there this morning with cold mix asphalt and a shovel. I think he might have done it? Can't prove it as I was biking by but found it pretty funny. Maybe the City will deal with it now?

I would be super interested in the same dialogue but for lights. I understand folks getting caught out without lights but I do think they should be required after dusk. Where do folks sit on the should/must require front and back bike lights?

NEW: i dove deep into the plans for several massive power plants being built specifically to power data centers crucially, they're designed much less efficiently than gas-fired power plants that are connected to the electric grid: www.wired.com/story/real-r...

The Real Reason Data Center Gas Power Plants Are So Dirty
A massive new gas plant in Texas will be built with much less efficient technology than regular gas plants. It’s far from the only data center power project to rely on dirty turbines.

My entry into the warmest year discourse... Over the years, I've used a couple of methods to estimate annual mean anomalies before they happen - using projected ENSO signals at the end of the previous year, or just from the relationship between the YTD data and the final annual average.

And before we get too worked up. CTA buses used 14.7 million gallons of diesel in 2024. This is 330 million pounds of CO2! Or 150,000 tonnes. NASCAR is ~5% of what Wendella's water taxis use in a year. www.transit.dot.gov/ntd/data-pro...

In response, corporates quieted down, didn't report as much, and set less ambitious goals. It was a neutering of the Overton window. Just something to keep in mind in our current climate as risk-aversion can overtake public recognition and ambition.

I want to add, greenhushing originated as a corporate response to criticism from progressive environmental advocates. Instead of applauding climate action by corporations, sustainability groups attacked them for not doing enough, doing it the way they wanted it done, or doing it fast enough.
