According to the United States Energy Information Administration's website, as of 2012, the average American home used 903 kilowatt hours of electricity per month. However, power consumption varies dramatically during the day and across the United States, with Louisiana homes averaging the highest consumption and Maine homes averaging the lowest.
Power plants have to be able to cope with changing power demands. Home power consumption is highest in the evening after people come home from work and during the weekend. However, energy usage goes beyond electrical energy used; many homes rely on gas and oil heating, which isn't measured by electrical companies. Because of this, total energy usage is higher in northern regions than statistical measurements regarding electricity typically indicate.Learn More
Watts are units of electrical power and amps are units of electrical currents. They cannot be converted into each other. However, electrical power is equal to current times the voltage of an electrical source, which means that one watt is equal to an amp multiplied by a volt.Full Answer >
Using Ohm's Law, 1500 watts of energy uses 12.5 amps. Ohm's Law defines the relationship between amps, watts and resistance. In the United States, electricity has a resistance of 120 volts.Full Answer >
A high-pressure sodium street light can draw up to 1000 watts, and an incandescent light used in the 1900s needed 320 watts. Some LED street lights require only 73 watts and, according to the U. S. Department of Energy, produce a higher quality of light.Full Answer >
For standard 120-volt service, a 20-amp breaker can support up to 2,400 watts on a single circuit. However, circuits should not be loaded to greater than 80 percent of their maximum capacity for long periods, which makes 1,920 watts the safe maximum for a 20-amp circuit.Full Answer >
