I never was against adding renewables. I'm simply pointing out rough estimates on our electricity usage throughout the year, and throughout the day.
Peaker plants, unfortunately, seem like the best solution. Natural gas is the best peaker plant for a variety of reasons. But then natural gas piped to a house for near 100% conversion efficiency is even better (rather than taking rather dramatic hits on conversion inefficiencies). Therefore, Natural Gas in homes is surprisingly useful, and will remain so for the foreseeable future.
We absolutely should be building renewables for the near and moderate terms. We don't have enough renewables for baseload yet.
> You've switched from talking about heating (presumably in climate that needs a significant amount), to talking about cooling California.
California has public electricity usage patterns. For better or worse, its the best data that we've got. I assume its somewhat representative of the energy requirements across the country.
Other parts of the country its way more complex because there's natural gas flowing everywhere. So its harder to convert Natural Gas heating vs electricity prices. Nonetheless, the concept of "This differs based on the weather" and "The weather changes dramatically every week" is universally true.
- mindslight 4y agoI wasn't saying you yourself were against renewables. Rather your argument seemed to imply that building one big peaker plant would preclude the demand for renewables since the peaker could supply the entire load all the time. I don't think we'll ever have "enough" solar+wind to supply base load, since night exists and winds calm down. Talking about "renewables" as a group doesn't really make sense. For example hydro is highly consistent and highly dispatchable, but waterfalls are rare. Spitballing, I would think cooling (especially with California's coast where it's rarely needed) would have much higher variability than heating, since people seem to tolerate a wider range of higher temperatures compared to colder temperatures. At least from personal experience once I enable the heat for the year it mostly stays that way, turning on when it gets even a degree too cold. Whereas air conditioning is a question each day of "can I get by with the windows open", and only when the answer turns out to be an unequivocal "no" do I turn on the AC (which then runs continuously to make up for lost time).
