Key term = voltage drop
DC moves only in one direction and has a constant voltage. This is a straight forward method for creating power, but the voltage tends to heat and often melt the copper wires. This makes DC transmission for distances over a mile dangerous, and sometimes impossible. Also, DC power cannot be changed by a transformer because of its unvarying voltage.
