Daytime super off-peak rates coming to SDG&E and community choice customers Customers can get the lowest available electricity price between 10 a.m. and 2 p.m. Monday through Friday.

Michael Powers, founding partner of Oceanside-based Stellar Solar, said lower midday pricing will give ratepayers some much-needed flexibility to shift their electricity usage away from the 4 to 9 p.m. block. 🔌💡

Dont get me started haha our electricity bills have basically 3-4x'd since 2020 (and we switched from socal Edison to sdge but pretty similar rates)

This segment went up quickly and is already generating electricity across a wide span of canal. It also includes enough vertical clearance to accommodate a small backhoe, as requested by the canal maintenance team.

Excited to attend the ribbon-cutting for the next segment of California’s solar canal initiative later this month in Hickman. Imagine generating solar power over 4,000 miles or so canals across the state. A lot of Sierra and Colorado River water to save via avoided evaporation.

Having a web form built is literally the example exercise in a "how to use agentic AI" LinkedIn course I glanced over!

Also used it to a script that gets a Google form for event submission that generates an email yes/no approval and adds events to a gcal!

If it's public facing or accessible to the Internet you need to be careful with DB attacks (not an expert here just know that's a thing).

BUT - you can totally get a web form built or a script to process an existing form into your DB. Claude very good for prototyping.

NGL this is great use case to try Claude code to setup a test DB in sqlite not anything else + give examples of how to access it. You should talk to a professional about cyber security concerns with DB access.

Story from 2017 but largely unchanged - BECCS (and indeed most "negative emissions") are largely a model fudge factor to hit emissions targets that are increasingly in the rear view mirror.

Cheap and easy to put CO2 in the atmosphere, hard and expensive to pull it out.

Does anybody know of a chart of refrigerant legality/phase-out timelines in the various major markets (U.S., EU, Asian markets)?

Yep. Totally agreed. Once individual entities would begin to realize there's this (relatively complex) unlimited funding tax credit mechanism to upgrade their infrastructure they'd be extremely excited.

Ah. But everything else I mentioned would've counted! Not sure on how good medium/heavy duty EVs are yet but would've also been a big big upgrade (obviously gone) especially with onsite solar.

One of the biggest adult kitchen learning steps has been to stop buying jarred pasta sauce and just buy canned crushed tomatoes or blanched tomatoes and make a sauce. So much better and so easy

There's giant blowers which pump air into the aeration tanks all day. They have big electricity loads! Did IRA credits cover replacement or repairs on those? Really feels like an underadvertised to segment that could've used it.

Fundamentally though people didn't know! If they knew they would've adjusted some of their CIP's to work in a basically free electricity project or front loaded CHP/digester projects which I think also benefited.

My wife works at a civil firm mostly doing wastewater, also some stormwater/infra work. How many ww plants could've benefited? She told me about a local plant who got floating solar for one tank and now generates so much they want to install onsite EV chargers to give employees free charging
