Nikolai Kardashev, a Soviet astrophysicist born in 1932, devised a method of rating advanced civilizations. Technological advances, according to Kardashev, could theoretically create conditions where a society could maximize use of energy. He categorized each of these stages as Type 1 through Type 4. Based on Kardashev's speculations where does our civilization sit today?
