Subject: Are there feasible alternatives to transporting energy as electricity?

Electricity. It powers almost all household appliances as well as the complex 
electronics we rely on to execute complex programs. I am wondering whether 
there are any possible substitutes for transporting energy in the form of 
electricity. Could we have power lines that transport high energy photons or 
something along this line? 50 years from now will our complex technology remain 
electronics or might it be powered by something else?
