If you use the 2019 numbers for Germany, an average 3-person home pays around 88.7 Euro ($105) monthly. Note, Germans don’t heat their homes with electricity or use AC units for cooling, so this is for plain regular home usage. You can also use the 1998 cost rate, and it’s 78-percent more.
So your German trend line, looking just ten years in the future, will be more than $150 for plain regular power. Chief reason? Coal plants will decrease, and nuke power is turned off in 2030. Wouldn’t shock me if the rate was near $200 a month (for just plain regular power).
Electric rates are about 25 cents per kilowatt hour in Germany and about 10 cents per kilowatt hour in much of the US.
I’m almost positive that Germany imports a lot of electricity from France that is coal-fired. And lots of French nuclear energy.
