@ragingloli Thanks, but I’m looking for an actual answer. Even if it requires a number of decimal places.

This is from your link mark Carl Sagan “Current status of human civilization:

Further information: World energy consumption

Michio Kaku suggested that humans may attain Type I status in 100–200* years, Type II status in a few thousand years, and Type III status in 100,000 to a million years.[4]

Carl Sagan suggested defining intermediate values (not considered in Kardashev’s original scale) by interpolating and extrapolating the values given above for types I (1016 W), II (1026 W) and III (1036 W), which would produce the formula

K = \frac{\log_{10}P – 6} {10},

where value K is a civilization’s Kardashev rating and P is the power it uses, in watts. Using this extrapolation, a “Type 0” civilization, not defined by Kardashev, would control about 1 MW of power, and humanity’s civilization type as of 1973 was about 0.7 (apparently using 10 terawatt (TW) as the value for 1970s humanity).[5]

*In 2012, total world energy consumption was 553 exajoules (553×1018 J=153,611 TWh),[6] equivalent to an average power consumption of 17.54 TW (or 0.724 on Sagan’s Kardashev scale). *

So we are a Type ZERO.
