Avoiding the Great Filter: Predicting the Timeline for Humanity to Reach Kardashev Type I Civilization

TL;DR

This paper models humanity's energy consumption to predict when we will achieve Kardashev Type I civilization status, estimating it will occur around the year 2371, considering environmental and energy source limitations.

Contribution

It introduces a model based on Carl Sagan's K formula to predict humanity's timeline to reach Kardashev Type I status, incorporating energy sources and environmental constraints.

Findings

Estimated year to reach Type I: 2371

Energy consumption trends analyzed for fossil fuels, nuclear, renewables

Environmental limitations significantly influence the timeline

Abstract

The level of technological development of any civilization can be gaged in large part by the amount of energy they produce for their use, but also encompasses that civilization's stewardship of their home world. Following the Kardashev definition, a Type I civilization is able to store and use all the energy available on its planet. In this study, we develop a model based on Carl Sagan's K formula and use this model to analyze the consumption and energy supply of the three most important energy sources: fossil fuels (e.g., coal, oil, natural gas, crude, NGL and feedstocks), nuclear energy and renewable energy. We also consider environmental limitations suggested by United Nations Framework Convention on Climate Change, the International Energy Agency, and those specific to our calculations to predict when humanity will reach the level of a Kardashev scale Type I civilization. Our findings suggest that the best estimate for this day will not come until year 2371.
