Weapons proliferation is definitely a strike against nuclear. A few other strikes: - It still requires mining, so is it any cleaner than solar + storage? - Waste is significantly less recyclable than other green energy waste. - High

When I was a young teen, I volunteered at the local YMCA to help set up a "haunted house" (actually a squash court) for Halloween. One of the decorations I pulled out of a storage closet was a display skeleton. I set it up and was

Tesla superchargers are rarely down. Not sure what they’re doing differently, but it shows that EV chargers CAN be reliable, but a lot of companies haven’t figured it out yet.

Yes, about 2000 moving parts in a combustion engine compared to 20 in an electric motor. The only reason ICE cars are comparable in price is the 100 years of supply chain competition. EVs will win, but gas and diesel will persist for a long

If it's 50 sheets of 1/8" balsa wood, it's about 166 lbs. If it's 50 sheets of 1.25" lignum vitae, it's about 13,100 lbs. 3000 lbs seems like a reasonable estimate.

And that’s why carbon taxes are so beneficial. It’s a shame they’ve been villainized and are unpopular.

It would still speed up behind-the-meter installations for existing grid connections. Rooftop solar, commercial and industrial customers adding battery energy storage, etc.

Who cares about the optimal climate, we just need the rate of change to remain at a low enough level that nature (including humans) can adapt. We seem to be on the edge of that limit already.

Vehicle-to-grid (V2G) is available in more and more EVs and will allow for this.

Is this a big deal? This report mentions electrolyzers hitting 80-95% efficiency back in 2004: https://www.nrel.gov/docs/fy04osti/36705.pdf The big H2 inefficiencies are still the compression, transportation, and

The age of solar + storage is here. It’s the least expensive option to add power to the grid today, and prices are still dropping while efficiencies are increasing.

Most of California’s electrical costs are due to transmission and distribution, and I believe a lot of those costs stem from reducing power-related wildfire risks. Last time I checked, 11 states received the majority of their electricity fr

Non-American here: What is the incentive for anyone in the US to pay off medical debt then? Also, I’ve read that medical debt is the number one cause of personal bankruptcy in the US; how does that work?

Pumped hydro is great, but the potential energy from gravity is actually really low. Stacking blocks will probably never work, and pumped hydro only works due to scale and existing geography. It’s also not modular and can’t be co-located w

“… our electrolyzer capex costs <$100/kW” Forget the DAC and natural gas, how are they generating green H2 for so cheap?

Yes, the valleys and rain don’t help either. The interior gets a lot of sun though, especially the Okanagan.

I think that used to be the case, but more and more often I'm seeing distributed wind and solar/storage reported as the cheapest way to add power generation.

Maybe it's similar to BC, Canada. They're mostly hydro powered, so they already have clean energy that's fairly cheap. As a result, the economics for solar never made much sense. However, with crazy-cheap panels and low hydro
