This feels like a bit of a BS comparison. Consumers pay many other fees beyond wholesale electricity to actually get power. It would be much more useful to compare what actual households pay (for US by state probably rather than a meaningless average).

For example, Edison in SoCal publishes these rates: https://www.sce.com/residential/rates/Time-Of-Use-Residentia... ($0.36 off peak and up to $0.57 peak usage)

PG&E: https://www.pge.com/pge_global/common/pdfs/rate-plans/how-ra... ($0.36 off peak and $0.50 peak)

When comparing these to the German $0.39, it doesn’t sound all that bad and at least they are dealing with a gas price spike because of a war. What’s Californias excuse? Also, many California residents have to deal with the stupid “public safety power shutoffs” because of unmaintained/poorly designed aging infrastructure that causes wildfires.
