Frying a turkey in a log cabin in the middle of a New Hampshire forest? What can go wrong!? At least there isn’t an open flame.
Happy #Thanksgiving everyone!

My son and I always behave myopically at hotpot. The ride home is always painful.

Second, can minor interventions help?
Increasing the font size of ratings reduced cancellations by 71.7%, effectively eliminating racial bias.
Displaying names upfront? Less effective. While there was a 30% reduction, it wasn’t statistically significant.

Key Findings:
First, we confirm the previous work. In the control group, drivers were more likely to cancel rides when passenger names were associated with African Americans.

We hope our curriculum can be a resource for towns and states considering adding more climate content. We are here to help, so do not hesitate to reach out.

Each lesson and discipline stands on its own, but many have touch points to lessons in other disciplines. So, students will see how CC is a multidisciplinary topic.

The curriculum is designed to fit into what teachers are ALREADY teaching. Our goal wasn’t to remake your syllabus, but to allow you to add more climate change content to what you are already teaching.

Each lesson plan contains a slide deck, background reading for the teacher, reading for the students, an assessment, and a list of MA and Federal standards that are met.
Roughly 25% is place based for MA. We plan to roll out to more states in the future (more below).

The curriculum is interdisciplinary, standards based, place based, and modular. We cover science, physics, economics, language arts, history, and math.

Hey #edusky, #energysky, #climatesky for the past few years we at @mitofficial.bsky.social have been developing a #highschool #climatechange curriculum. We’ve teamed up with 5 amazing curriculum developers, all current MA HS teachers. Climate Action Through Education. Learn more at cate.mit.edu

We use Best Subset Selector methods to ask "How many distinct daily prices should you?" The answer is really cool. Basically, there's not much advantage to having more than 2 prices per day. Less is more!!

The more information timely the information you use, the better. This shows what happens if you call the CPP events (i.e., choose the time periods where there is a CPP) based on day-ahead or real-time information and whether you choose the price based on hay-ahead or real-time prices.

CPP efficiency gain depends on how many CPP hours you choose and how you pick the price "adder" during those hours. If you choose the same adder for every CPP event, the program doesn't do much! (This is how most programs are organized)

We use data from all 7 organized wholesale electricity markets. Using this extension we show that #TOU pricing gets rid of about 10% of the inefficiency that exist from flat pricing. #CPP gets rid of another 10%. Furthermore they do not compete, so combined they get rid of about 20%.

The second RCT focused on reducing energy waste. Freezer doors left open at donation centers were a major issue. We installed alarms to remind staff to close them quickly. This simple nudge reduced the frequency of alarms by up to 93%, saving energy and equipment lifespan.

In plasma collection, dropping sterile materials means immediate disposal. We placed disposal bins for easy tracking, coupled with visual cues, and #KPI targets for the center managers. Result? Up to 70% reduction in wasted materials and significant cost savings.

Comparing observed emissions vs. a “perfectly competitive” scenario, we estimate emissions would’ve been higher without OPEC, as competitive markets would drive down prices, worsening climate impact. The impact varies by year depending on the effectiveness of OPEC as a cartel:
