What will be your towing powerplant in 10-15 years ?

Even if we are driving electric trucks there will have to be some mobile method to recharge these trucks . What will that be , solar , wind , large petro fired generators , Diesel/electric today powers trains and ships .
My self I believe that there will be infernal combustion engines on the road for many , many years to come . I do not see large construction equipment stopping to recharge or farmers with acres of beans to pick stopping to recharge . I wonder what kind of truck will deliver your new Prius !
