We know that one barrel of oil produces around 800 kilowatt-hours of electricity. We need to find out how much kilowatt-hours we use per year. We can multiply 27x12. This gives us 324 kilowatt-hours of electricity a year. That means that we will use one barrel of oil, or 41 percent of a barrel of oil a year.
Something seems off here, apologies. This is either on my behalf, or the information provided is incorrect. If not, there you go!
