You’re right that cold winters in northern latitudes present additional system constraints. But that doesn’t mean the renewables + storage strategy is flawed, it means we need more transmission and more storage, and gas backup will linger longer in such areas than it does in warmer areas. We’re still early in the transition and have a ton of low hanging fruit to capture before we need to really focus on the remaining 20%.
Capacity and generation are two different things. Grid operators have capacity markets that ensure peak load can be met, and incude generations assets, demand response, energy efficiency, etc. Batteries absolutely coumt as capacity so long as they are managed to do so.
They weren’t talking about how long EVs have been around, but for anyone curious EVs generally predate ICE cars and were quite popular around 1900. https://en.m.wikipedia.org/wiki/History_of_the_electric_vehicle
We had 3 days of -10 to 0 ish in Colorado over MLK Jr weekend, my H2i kept 68F in the house no problem. It dropped to 67 a few times during defrost cycles, since I have no backup. It works great, im sure your house did just fine unless is severely undersized.
You added an extra 1000 lbs to the heaviest version, then rounded up. The whole entire point of standard weights is so numbskulls don’t just make up numbers for how much things weigh, like you are. The leaf is 350-3900 lbs, not 4900 lbs, not 5000 lbs. Please go back to elementary school.
A leaf is 3500-3900 lbs, not almost 5k lbs
We’ve moved from 17% to 40% of total energy production coming from renewables since 2020
This what you said. You’re comparing a 2020 number without nuclear to a 2022 number with nuclear. That’s dumb and misleading. That doesn’t make me a douche, it makes you wrong and petty. Grow up and just try to get your numbers and facts straight.
You said renewables are 40%, which is wrong. Then you sourced articles showing that carbon free sources are 40%, which includes nuclear. Nobody calls nuclear “renewable”, so I suggest getting your language straight so as not to confuse.
Source? I haven’t seen final numbers for 2023 from EIA yet, but 2022 was like 22%. The growth is accelerating as economics change, and in large part the IRA (thanks Biden), but it’s not 40%. I’m speaking of electricity production, but I can’t think of a reasonable metric that’s anywhere near 40% nationally. Let’s try to stick to reality here.

The solution of course is having a payroll type tax that funds parental leave. Everyone pays in, and the government pays out so companies, large and small, don’t have to deal with the issue you’re talking about. I’d like my employer to have zero say in things like this, unless they want to go above and beyond. Same for healthcare. Let companies be companies, and let’s use taxes to find societal needs
Wen you elect fascists they don’t always allow free and fair elections in the future so this “similar wins int he future” clause is ignorant. Especially when the fascist in question already attempted one coup to stay in power when he lost an election.
Awesome. I so wanted the Sanco2 but the price put it out of reach, and we don’t use enough hot water toake the payback remotely reasonable. For anyone else reading, it’s an R744 (CO2) refrigerant system that’s massively better for the environment than HFCs (and HFOs) as well.
There’s a federal tax credit worth 2k for HPWH. I’m not aware of any Ohio specific subsidies, although there are programs coming through the IRA that are run through the states and will offer more incentives.
You spent somewhere around $54k in gas over 7 years @15 mpg and $3/gal. I wouldn’t take an Escalade for free if I drove that much.
The overwhelming majority of even high end cold climate ASHPs do not function at -40 C/F. -20F, that’s doable.
Second the NEEP database. I’d just add that the lowest temps listed here aren’t the actual equipment minimums - each model has a cutoff temp where it will literally shit the bed (except ground source of course). For my mistu hyper heat, it’s -26F. Capacity will keep dropping after -13F though (where it’s still at like 80% I think).
You made the most sensible choice and are dramatically reducing you gas use, so you should feel good about that! I have a new Mitsu hyper heat (Colorado here), but recognize it wasn’t the most cost effective system and ultimately just really wanted it. It’s bonkers how well it work though. We’ve only hit 10F this last weekend but it didn’t skip a beat. Looking forward to -10F. For most people, keeping a gas furnace for a few weeks a year, and using a smaller heat pump than you would spec if only using a HP makes a lot of sense. You’re not missing much (and some would argue that peak winter demand in an electrifying world is a big problem that has backup gives us more time to solve anyway).
MFers need a refresher on the concept of absolute zero.
I think I gave off the wrong impression that these are more linked than they are, sorry. Many states require cost effective EE because it’s generally good policy (benefits outweigh costs), and some of those benefits include not having to build new capacity. PUCs generally also support infrastructure investments, and with guaranteed rates of return on most T&D for example, it’s a no brainer. So states are often doing both, and there are varying options about the merits of each. To your question though, one notable recent example is the gas pipeline that Gov Cuomo vetoed, which led to more gas efficiency programs in downstate NY.
I’m also embarrassed to report I can’t think of a good source for you since I’m in the industry, other than primary sources like utility financial statements, rate cases, state regulations, etc. Hope this was helpful - it’s a fascinating industry.
You’re a quarter behind. Big drop 2024Q1, but you’re right that the story has been growth - just slower growth than Tesla has promised, even with massive price cuts, and now we have a contraction. A lot of people dislike Elon because he’s a fucking tool and this has to be a partial factor, we just don’t really know how much.
