  1. Most energy sources ultimately convert into electricity by powering a generator. At its simplest, a generator has rotator, a shaft and an assembly made up of magnets surrounded by a conductor. When the energy - wind or water, for example - moves the rotator, the shaft spins, causing the magnets to move. The spinning of the magnets is what generates voltage, which drives electric current into power lines for distribution.
