  • When you “mine” natural gas and burn it for heat, it’s gone. It disappears (and produces harmful GHG in the process) You have to keep doing this to get more output.

    When you mine materials for batteries, you end up with a physical thing that persists, can be used over and over and can be recycled into new batteries at end of life.

    This means the amount of mining required for renewables + batteries is proportional to only the addition of new capacity, whereas the amount of “mining” for fossil fuels is proportional to the total gross energy output (including significant heat losses)

    We’re mining a lot of battery materials now, but that’s because we’re adding a crapload of capacity.







  • Nuclear: to maintain baseline power (as opposed to peak power) for emergency scenarios.

    That’s an incredibly expensive emergency power supply. If you can’t operate a nuclear plant 24/7 it’s going to take a veeeeerry long time to pay off the massive capital investment.

    And that’s the crux of the issue. These plants won’t be supplying baseload. By the time they get built we will have twice as much rooftop solar, and lots more utility wind and solar. There will be very little room for them to operate at a spot price that earns them money.

















  • Counterpoint to your counterpoint: Due to renewables becoming cheaper and cheaper, private investment is pumping in capital en masse because the economics work out on their own. There is less and less room for government policy to set the direction. The market will decide.

    I honestly don’t know how a nuclear power plant could be anywhere near profitable when 30% of the time we have negative power prices due to rooftop solar. Batteries are already edging out gas plants on a LCOE basis, and they’re getting cheaper by the day.

    By the time the Liberals get in and try to implement their nuclear fever dream, there will be no cheaper form of energy than distributed solar + batteries and no sane financier will back anything else.
