Does it take more energy in transmitting electricity uphill than it does downhill? Is the loss during transmission more in one of the two directions?

Very, very small difference, so small because gravity is so much weaker than electricity. An electron going through a potential of one volt is a convenient measure of energy called an electron-volt (equivalent to ~10^-19 Joules). An electron moving up one hundred meters requires an energy of about 5 billionths of an electron volt. So in terms of circuits, the voltage required changes by billionths.
