In one of the videos I said that a typical American household uses energy at a rate of about 10,000 joules per second. A shorthand unit for this would be "10 kilowatts". Using energy at this rate costs about $1.50 per hour (this is not quite right, as it assumes that all the energy is electrical energy, which is relatively cheap, but let's go with this for an estimate). How much does this energy usage cost for a year?
