  • I think it’s quite a bit more complicated than this. The concept of disposing of something always existed, but for most of human history that meant just leaving waste where it fell or at most tossing it at the edge of the village.

    It’s only once larger settlements appeared that a need to concentrate waste in one location to avoid despoiling the entire area became necessary. This was greatly compounded with the invention of manufactured materials that don’t biodegrade like glass and plastic. There was no other solution to this than to concentrate and bury waste so it didn’t end up everywhere.



  • This one goes into pretty good detail about the challenges in CA in particular:

    But at 50 grams of CO2 per kWh, the ban on nuclear makes a significant difference. “Without nuclear, there’s about a 45% increase in total system size, which is really quite substantial,” says Farnsworth. “It’s a vastly different system, and it’s more expensive.” Indeed, the cost of electricity would increase by 7%.

    Going one step further, the researchers performed an analysis to determine the most decarbonized system possible in California. Without nuclear, the state could reach 40 grams of CO2 per kWh. “But when you allow for nuclear, you can get all the way down to 16 grams of CO2 per kWh,” says Farnsworth. “We found that California needs nuclear more than any other region due to its poor wind resources.”

    TL;DR you can do it with batteries it just costs more, and getting consumers to accept higher electricity prices in order to protect the environment is already going to be a tough sell politically. Of course, so is nuclear, so I do support continued efforts into some more novel sources of baseline power such as floating offshore wind and advanced geothermal. However, these are not ready to be implemented at scale today and the federal government is currently making offshore wind nearly impossible to construct. So I don’t know. There aren’t any easy answers, unfortunately, but we have to hope either the political or technological landscape changes somehow to make deep decarbonization possible.


  • California is not a tropical climate. Solar resources in the winter can actually be quite poor in most areas due to low sun angle and high cloud cover. Of course the summer is the opposite but we do need power year-round.

    Most analyses show the cheapest way to fully decarbonize will include some baseline sources like nuclear. I’m skeptical with CA’s bureaucracy challenges and its political unpopularity it will pencil out to be nuclear but we’ll see. I think all options should be on the table in a climate emergency.

    Keeping the existing plant is a no-brainer though.
