Good question, I just checked. The numbers I can find for 2022:

Renewables: US: 21.5% Germany: 44%

Nuclear: US: 18.2% Germany: 6%

Fossil: US: 60.2% Germany: 45.9%, 20.1% from lignite (brown coal)

So pretty clear win on the renewables for Germany. Adding Nuclear for "clean energy" it's still pretty ahead. However, Fossil in the US is mainly gas, which is cleaner than lignite. Hard to quantify.
