I research, publish, mentor & advise on offshore wind power, electric vehicles #EV, and vehicle-to-grid power #V2G. Prof at U of Delaware. #energytransition #energysky 🔌💡 🔌🚗
Incisive article “Power Struggle” by @jefftheyoung.bsky.social on how US policy drives investment, factories and jobs out of USA, favoring China. Quote (below) by @billmckibben.bsky.social if US blocks new expanding technologies, it could become the Colonial Williamsburg of internal combustion.

Largest offshore wind project worldwide, Berwick Bank, 4.1 GW, approved contingent on avian study & mitigation if needed. How big 4.1 GW for Scotland? 🟰 power of 2x households OR 🟰 to taking ALL cars of the road. Running well before 2030.

First text is from my in-law, a capable #mariner. #Weather forecasts appear to be the same, but suddenly way less accurate. 2nd from meteorologist colleagues on how specific staff cuts degrade forecast accuracy. One of many ways the national infrastructure we rely on is being silently destroyed.

David Ricardo's theory of comparative advantage explains why free trade can benefit both sides. This also helps understand the massive ignorance and coming damage of the new US #tariffs. First, a readable explanation from @gregor.us: https://bit.ly/3Gcac6u

New SAE EV standards just approved: one is #V2G for AC, making V2G lower-cost and easier to mass-produce. The other standardizes the Tesla connector. Link is the story on how those were written.

1/2 Four #offshorewind projects cancelled by developers in recent weeks. But most news garbles the basic facts: OSW developers must fix electric price 5+ years before power-on, so bids from 2017-2019 are now hit with inflation and interest⬆️. www.nytimes.com/2023/11/02/n...

Electricity from nuclear versus wind+solar. Thecommon fallacy, stated as fact, is that nuclear is "bigger" thus more able to displace CO2. Actually, W+S grows exponentially, is lower cost, & now exceeds nuclear production.
