You have identified the primary reason why the US consumes more energy per capita than France, German or Switzerland and it is not because Americans are naturally more wasteful than residents of those countries. Instead, it is primarily based on the fact that our country is much larger, with a population density that is quite a bit lower than any of your examples. As you pointed out in your comment, if you draw circles around urban areas in the US, you will find that we walk, live in smaller spaces and take public transportation enough to lower our average energy consumption to something that is close to that in your example countries.
You also point to measures like life expectancy, child mortality and education as measures of wealth. You ignore measures that seem important enough to people to attract them to the US and cause deep queues waiting for permission to emigrate here. On average, Americans that do not live in dense, walkable cities live in larger homes, have more property between them and their neighbors, have the freedom to travel on their own schedule, and can take advantage of entertainment and employment opportunities that are not within walking or biking distance. Our freedom to move requires less efficient, but often more comfortable transportation in the form of personal automobiles. Our larger homes require more energy to maintain at comfortable temperatures. Our employment flexibility often comes with an energy cost.
I think many of us are less wealthy today than we were when I was a child and gasoline cost about 25 cents per gallon. I lived on a suburban street with teachers, engineers, mechanics, retirees and airline employees. Three of my neighbors owned their own plane. About half had a swimming pool and/or a powerboat. Most had cars large enough to drive a carpool so we could get to swim meets, baseball games and wrestling matches in nearby cities. Most of us took annual vacations lasting at least two weeks that involved thousands of miles of travel in comfortable automobiles or campers.
I've been fortunate enough so that I have been able to provide my own children with some similar experiences, but I would bet that most teachers, mechanics and engineers have not been as fortunate as their earnings have failed to keep pace with the cost of liquid fuels that enabled many of those "luxuries" to be affordable for the masses.
