Fernandez: Startups risk failure by fixing offtake prices before FEED engineering
“Many times Off-takes are priced in a way before engineering, you know, failed one, failed two, engineering have been done, and it's based on optimistic CapEx assumptions. Now, when the companies go through the engineering process, and they actually get to a fe…”
Founders must start their next project before the previous one finishes

Phillips: High-frequency data access matters more than edge processing power
“I've been a little less concerned about that, because for computation, you can always be very efficient about your algorithms, and you can make trade-offs from the algorithms. The reason we're more concerned about the data is if you don't have the data, you do…”
Patel: 100x scale drives 70% cost reduction across climate tech

Distributed energy rate designs risk favoring the wealthiest ten percent
“I mean, a lot of people who buy these distributed resources today EVs very much being that, solar, whatever, are generally very wealthy people, and so are we now doing rate design and setting operational constraints based on what the richest 10% want, or are w…”
Kimber: Most corporate green energy buyers are quietly saving money on power
“The kind of dirty little secret is that most of those companies have been saving money too, right? So they've all been, you know, heroes for the climate, but they've also been kind of making money out the back door, buying really cheap energy from guys like me…”
Green cement is commercially unviable if it delays building construction timelines
“Cement costs are about maybe two, three, four percent of an overall building cost. The cost of labor and the time it takes to build a building are a lot higher than that. You could have a much lower carbon cement, but if it takes three to five times as long to…”
Pfund: Climate tech is not SaaS and requires policy and advocacy integration
“It, it's not just a technology game. This is not like investing in SaaS or you know, a traditional tech profile. You have to weave your technology into a broader framework that really matters, and that means engaging across policy, technology, investment, and …”
Storrow: Winter Renewables Extend New England Gas Plants' On-Site Oil Reserves
“These gas plants that we keep talking about as a sort of a reliability buffer, they've all installed oil fire backup. They have oil tanks on site. So if the spot price for gas gets really high, or the pipeline got constrained, they can switch over. And start b…”
Donti: Average-Case ML Fails on Grids Without Physical Boundary Guardrails
“The fact that you can get a machine learning algorithm that learns to do something nuanced from data and does it right most of the time doesn't help you in those times when it does something wrong that one time that really blacks out your grid. So this is wher…”
Ramanathan: Prevailing wage mandates create tension with low-cost green power
“Because if you want really low-cost green power you know, creating jobs with prevailing wages and having apprenticeship programs, you know, there's some tension with that.”
Shah: Deploying nuclear power creates an 80-year international relationship
“When you think about what it means to deploy nuclear power into a country, it means an eighty-year relationship with that country.”

Boyle: 'Used and useful' regulation penalizes utilities for early coal retirements
“That's profit that's built into shareholder expectations. Now you're asking them to shut that down. That creates a lot of uncertainty. Is the regulator going to continue allowing me to earn on an asset that's no longer operating? Like the regulatory standard i…”
Boyle: Reusing retired coal interconnection rights fast-tracks new renewable energy projects
“One of the things we wanted to highlight with this report, again, with the local renewables, is you can potentially reuse the interconnection rights that utilities have at these coal plants and transfer them to new renewables that can get ahead of the queue an…”
On-the-Job Apprentice Training Cuts Into Electrical Contractor Profits
“Because it's not just a matter of, hey, yeah, let me hire people, and then, because you have to go with them through training, and so it might take you a month to two months for them to be ready to finally go out on the field, know how to interact with custome…”
