    By that logic, a country can't make long-term investments, and can't provide unprofitable services that have other benefits. My two questions challenged your circular reasoning.

    The framing comes from this reasoning: not enough resources yet to build 100% renewable generation + storage => still need nuclear or fossils for now But many people think this way…

    I'm saying there's no storage solution yet. Even combining all storage types, you'd still run out of materials (battery) or locations (hydro) before finishing. It's not speed vs sp…

    People often don't realize that intermittent renewables must be paired with backup generation or storage. But energy storage at the scale of a 100% renewable system is currently an…

    Thank you for pointing this out. I think most people assume that companies are just being greedy when they solder previously socketed parts, for example. I'm not saying it's never …

    You cover a lot of interesting topics. Some exposition: Reporting power is easy with the power triangle. It's a mathematically exact concept. Measuring power is a different story. …

    I don't have a down button, but I can see why someone used theirs. 1. Why would you verify local need, if the need is national? 2. Why would you verify inability to pay with abilit…

    There are actually three parts of the power triangle: real (W), reactive (VAR), and the hypotenuse apparent (VA) power. If voltage and current are exactly in-phase, VA=W and VAR=0.…

    It's the grid reliability organization for the US and Canada. There are more details in the reliability reports they publish. https://www.nerc.com/news/Pages/California-Mobility-Ce…

    Here's a real and recent news article about how potential risks and opportunities are being explored regarding electric vehicles and the grid [1]. It basically says they're looking…

    Seems like you didn't need fixed point in the first place. It's for when you need guarantees.

    We already have carrots and sticks to ensure reliability. That's what regulation is for. Changing those is a lot easier than changing companies.

    I've worked for one of the big three you mentioned. Probably a different one, or at least a different group, since the culture seemed fine to me. I can't think of single a time whe…

    The PDFs below are a little dry, but they have noticed and cared since at least their 2018 forecast. As for the remedy, what exactly does it mean to lose public utility status? [1]…
