Some electricity is lost when electricity travels along transmission lines, as transmission lines have some resistance to electricity flow. The higher the voltage, the lower the amount of electricity lost.
Once at a substation in a community, the electricity is then distributed to transformers, which reduce its voltage level so it can be distributed to individual homes and businesses. A smaller transformer along a residential street reduces the voltage levels to 120 volts for lights and 240 volts for larger appliances in homes.
Scientists are working on storing nuclear energy in a battery, which they predict will provide up to a million times more energy than a conventional battery.
