The Kardashev Scale Type 0: Why Earth is a Level Zero Civilization
“Based on our energy use, in 1973 astronomer Carl Sagan estimated that Earth represented a Type 0.7 civilization, more current assessments put us at about 0.72. What does this mean? We’ve had 4.5 billion years and we still haven’t made it to a Type 1 civilization.”
