Modeling Monday: How clean are EVs, really?
Short answer: it depends on the question. Attributional vs. consequential LCA, average vs. marginal, short- vs. long-run... the metric can flip the answer. 1/🧵

I'm dipping my toe back into the academic literature: who's got recommendations for good papers around transmission network reduction algorithms? 🔌💡

I promise to always boost anti-Prop 13 content, especially if it's got information and jokes.
OK but so:
Oil companies tried in 2010 to kill off the C&T program via state ballot initiative (Prop 23, so named bc it was the reverse of AB 32). They failed.
But on the same ballot, they *did* pass Prop 26 (so named bc it doubled down on CA's disastrous Prop13)

NEW: Bezos-backed EV startup Slate Auto dropped a few versions of its electric truck in CA over the weekend, ahead of a formal reveal Thursday.
Sources told me Slate has privately touted the truck's 'Transformer'-like shapeshifting ability.

I'm sure plenty of people have downloaded copies, but who's going to host something as canonical and convenient as NREL/EIA? This is a huge step back for the research community.
I separately heard NREL tools and data are shutting down today, and EIA may be next 🔌 💡
If you use tools and data from NREL, I recommend you download them now.

The fun story of Ann Arbor planning to build a duplicate distribution grid:

By creating a supplemental utility that will focus on scaling up rooftop solar, battery storage and microgrids, Ann Arbor, Michigan, is taking its clean energy future into its own hands, stakeholders ...

Energy Exemplar has blocked all TU Berlin students from academic licences for their energy modelling tool PLEXOS because competitor PyPSA is developed here. While deeply shocked, we believe in turning the other cheek. So we are offering all Energy Exemplar employees a free licence for PyPSA.

Because of the Inflation Reduction Act, other policies, & innovation, US installed solar & wind power capacity in 2030 is now projected to be double what it would have been before the start of the Biden Administration. Double! That’s good. Let’s do even more now. www.whitehouse.gov/briefing-roo...
![As the manufacturing base expands, solar and wind deployment are projected to grow rapidly—considerably faster than projections before the Investing in America agenda was signed into law. According to the latest Annual Energy Outlook (AEO) forecast[1] from the U.S. Energy Information Administration, the United States is on track to have 338 gigawatts of solar capacity in 2030—nearly twice the capacity forecasted in the beginning of 2021 (Figure 3).[2] Likewise, for wind energy capacity, the latest AEO forecast estimates that the United States will have 300 gigawatts of wind turbine capacity in 2030, a 43 percent increase from their 2021 projection (Figure 4). For context, this estimated capacity from solar and wind in 2030 would be roughly double the total existing renewable capacity on the grid at the end of 2022.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:xjnxcxe2pn5lwp6z2gxapbrl/bafkreigt7j7ktbp4c4f64xvqj57u4dsgou3tux2nliujcooe7mmsd7kmzi@jpeg)
