And yet CO2 per capita is much lower in Germany than in the US. So Germany must also be doing something right.
Europeeans tend to have less disposable income and be less consumerist, smaller and better heated/insulated houses, less cars per household, &c.
A quick Google search suggests ~350g CO2 per KWh in Germany vs. ~400g in the US. Looks plausible to me. Germany uses coal but also has a very substantial share of renewables. Another quick search also shows that 60% of electricity in the US is from fossil fuels. The rest is nuclear and renewables in about equal amounts.
