EVs Now Sell Faster Than Gas Cars In The Used Market | Carscoops
Used car prices are climbing again in 2025, and buyers are slowing down, though not when it comes to EVs

Electricity update - The cost of electricity is on the rise in our area. The reason here is because PJM has been slow to increase transmission & roll out new capacity for renewables as fossil fuel plants that are not competitive shut down. (Growth of data centers also contributes). 🧪🔌💡☀️💨💧🔋 🧵

Gas update: Seems I may be owing Kevin a dinner... It took us three phone calls & several week's wait to turn off our gas last spring. Then we had to dispute an estimated bill (from a smart meter!) that was 10x greater than our actual gas use. 🧪🔌💡☀️💨💧🔋 🧵
I'll wager a month's fixed gas fee that it's a helluva lot easier to start giving them money again than to stop!
though knowing utility websites and bureaucracy, that might be a risky bet...

Despite "vibe" reporting to the contrary, EV sales are growing at +8%. The *global* share of internal combustion vehicles continues to decline, replaced by hybrids, plug-in hybrids & BEVs. Car makers betting otherwise are selling buggy whips. 🧪🔌💡☀️💨💧🔋 electrek.co/2025/11/12/e...
EV sales *still* have not fallen, cooled, slowed or slumped. Media is lying to you.
After two years of headlines begging for failure, EV sales keep defying false media narratives that they are dropping, and continue to rise.

October Electrification Update- We have now gone 7 mo. without using fossil gas at home. We'll turn the gas back on soon to cover temperatures <20°F, but the 3-season heat pump has managed just fine this year without gas. Here's my monthly update. 🧪💡🔌☀️💨💧🔋

I want to glaze and fire these eight charts as ceramic wall tile accent pieces. They take the trends from the EIA data (2021 - 2025) and extrapolate them to a 100% clean energy grid for Texas by 2035. Seems doable.

The headline here is that West Australia is reaching 84% renewables on a near daily basis, but perhaps the real story mentioned in there is that the Australian National Grid is now reaching nearly 79% generation. 🧪🔌💡☀️💨💧🔋 reneweconomy.com.au/death-of-bas...

With a current value of $0.001 per ton, it does not look like coal will be making a comeback in the United States. That's the outcome from a recent coal lease bid for *subsidized* coal. They lowered the royalty rate (& cut environmental regulations) to encourage the sale. 🧪🔌💡☀️💨💧🔋 A short 🧵
