Volts is not a measure of energy so there is no way to have 18volts of energy. Energy is measured in Joules, or sometimes calories Watts is a measure of energy transferred per second. In electrical terms, 1 Watt is equal to 1 Volt at a current of 1 Amp.In one second, 1 Watt will transfer 1 Joule of energy.
