Indeed I have traveled, and I am in favour of nuclear and renewables and batteries for pretty much the reasons you state. There are other issues (concrete production comes to mind, and it always bugs me that houses in Europe are so dependent on concrete when its a huge emissions source) but when you're running your building equipment and factories and transit networks on zero emissions electricity (so we can include nuclear, which I suppose isn't renewable but is still very low carbon) then the building, the car, etc. have lower embodied carbon as well.
