RE:RE:RE:Great US job numbersWell nature has already figured out how to pack the most available energy in the least amount of mass (highest energy density). Hydrocarbons, which are already stored solar energy made through natural biological and geological pricesses (phytoplankton to kerogen to hydrocarbons) store 60 times more available energy per kilogram than the best lithium battery. Some oxygen, a spark for inputs and you can power cities. About the only other practical source of available energy with orders of magnitude higher energy density is the binding energy release from uranium nuclei in a fission reaction.
To your point, the US (North America) also has piles of deep water ports on two oceans abd the GOM and soon the Arctic as well. Plus the rest of the planet is crazy, unstable run by autocratic psychopaths so why even bother investing a dime there?
