New report: bit.ly/PS2k23 200A panels should be OK for most homes to fully electrify, including #EVs. What about smaller panels? A 20kW draw is the level when a 100A panel may need to be upgraded. For 400 homes from 2020–22, homes rarely hit it (0.001% of the time).

Steve Jobs died more than 10 years ago. But CNN’s feature photo for its story about the new iPhone shows him front and center come on guys.

Texans could use 35% less energy to keep their homes cool during our brutal summers. Really. Our analysis provides some real-world numbers to the potential of smarter cooling. All the tech we need is already available. We just need to use it. pecanstreet.org/2023/07/smar…

Y'all, it simply doesn't get more 2023 Austin than a Tesla towing a smoker down MoPac

OK - just learned that heat pump clothes dryers are a thing, and supposedly use 50% of the energy of an electric resistance dryer. And, apparently some run off 120V. WTF? How am I just hearing about this given half of my feed is about heat pumps?

#HVAC systems are meant to cycle on and off at regular intervals once a thermostat setpoint is reached. Undersized HVACs (or leaky homes) can cause systems to run continuously for hours when it’s hot outside. #COTW #energy

We may not think about them often, but refrigerators use a lot of electricity. The shorter and more efficient each cooling cycle, the less energy is used. An efficient fridge can save you money on your energy bill. #COTW #energyefficiency

To reduce energy waste, check/replace the gaskets around the door & avoid placing it near a heat source (oven or window). If everything seems air-tight and it runs constantly, it might need a repair or replacement. #COTW #energyefficiency

1/ Our Data Analyst @cmerski is speaking at @IEEEorg Rural Electric Power Conference today about #EV charging. Perfect timing for our #COTW, which shows how EVs could push homes to upgrade their electric panels. Or..maybe not. See bit.ly/panelsize for a deeper dive.

Not all EV charging is equal. The charge rate of EV batteries changes depending on the model of the vehicle and the home charger. Let’s take a look. See more at pecanstreet.org/chargingsmar… #energytwitter #cotw #electricvehicles

So?? Homeowners can and will adapt charging habits without strong incentives. The right integration technology and rate structures can scale this trend & allow EVs to use excess solar AND power AC systems during hot & cold weather when the grid is stressed. #solar #EV #grid

Home B often charges during the day or after work during winter and shoulder seasons. Charging an EV when solar production exceeds home load is smart. On hot TX summer afternoons, solar powers the AC system; the owner shifts EV charging to early morning. #solar #EV #grid

Home A consistently charges overnight which is preferable in TX. On average, the home produces almost enough solar to cool the home during hot summer afternoons. Note: there is no EV charging during peak demand hours to add more stress to the grid. #solar #EV #grid

This week’s chart: 2 Austin homes with EVs and solar, which show seasonal relationships bt EV charging, home load and solar. EVs will be the largest & most flexible home load. Managed well they will improve home energy performance and grid resilience. #solar #EV #grid

Huh, one state leads in all three. You'd think this would be a source of pride in that state and yet... #txlege #txenergy #energytwitter
In 3 charts, here are the states leading and lagging in renewable energy. insideclimatenews.org/news/0…
