Last year I went through a calculation using data about worldwide energy consumption to calculate a Kardashev score for human civilization and got Type 0.7248 in 2012. BP’s data for 2013 was recently released (page 40, the “Total World” row), so let’s get calculating.
As a reminder, the equation for the Kardashev Type is
Where is the average power output. They find a value of 12,730.4 megatoe, or million tonnes of oil equivalent for total energy consumption. This gives J which if expelled in a year gives W. Plugging this into the above equation gives
Still a long ways from Type I.
