Comment on Trump Is Obsessed With Oil. But Chinese Batteries Will Soon Run the World

  That is excellent and cost effective, however what then when there’s no sun out or it’s cloudy? Will you not travel?

    This is one of the concerns I have watched with interest ……

    • with the first mass market push to wind “grid won’t be stable with any significant amount”
    • as wind and solar became more popular “renewables can only be 30% without destabilizing the grid
    • this past summer “with today’s renewables and storage technology, the cheapest most stable option is 95% of the grid”

    Your concern may be technically and historically valid but is rapidly disappearing

      That’s about right. I have product tío and storage at a 115% of my consumption, which translates to actually using some grid because the sun is not always out (although you would think it is where I live, lol). That allows me to finish the year with an excess credit of about 200 dollars with the electric company, but I still use some of the grid during hurricane season and very rainy periods of 3 or more days, which rarely happens.

    You’re not going to believe this, but solar panels will still work even when the light is reflected or partially blocked by clouds. Rain actually helps to keep your panels operating efficiently by washing away any dust or dirt. If you live in an area with a strong net metering policy, excess energy generated by your panels during sunny hours will offset energy that you use at night and other times when your system isn’t operating at full capacity.

      That’s crazy. I never would’ve guessed. Did you also know solar panels have a theoretical limit of 33%, which is diminished even more when sunlight is further blocked? Wow! That means they’re horribly inefficient and even more so when less light comes in! Who knew! So really we’re talking about pennies on the dollar at the end of the day when something like supplying a grid at a larger level would mean nuclear.

        Did you know fractions are predicated on a base value?

        So really we’re talking about pennies on the dollar at the end of the day

        That’s definitely an aphorism.

    That’s what the batteries are for?
