U.S. Energy Converted into Time Travel
You’ve probably thought about it once or twice. Exactly how much money is spent on residential electricity in the U.S. each year? It may not seem like a large amount when you pay your bill every month, but with over three hundred million people living in our country, that amount certainly adds up fast. Let’s take a closer look.
The Energy Information Administration (EIA) has estimated that in 2012, the average annual electricity consumption for a residential utility customer in the U.S was 10,837 kWh. They have also stated that the residential sector paid an average price of 11.88 cents per kWh.
According to the U.S. Census Bureau, in the same year there were 132,452,405 housing units (defined as a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied as separate living quarters.)
Time for some quick math…
10,837 kWh multiplied by $0.1188 comes out to $1,287.4356. If we round this number off, each house in the U.S. paid $1,287.44 for electricity in 2012, on average. Multiply that by the number of housing units and we get a grand total of $170,524,524,293.20…for a single year!
Now let’s take it one step further.
When you calculate it out, the total amount of energy consumed in 2012 comes to 1,435,386.71 gigawatt hours (GWh). Dividing that by 8,760 (total hours in one year) gives you 163.86 GW.
According to Dr. Emmett Brown himself, also known as “Doc,” exactly 1.21 gigawatts are required to take a ride in the DeLorean time machine. So if you saved all the electricity consumed in the residential sector of the U.S. for one year, you would be able to travel in time 135 times!
