Original Text

Half a century ago, Russian astronomer Nikolai Kardashev was asking similar questions when he came up with a way to measure technological progress; even when we have no idea exactly what it might look like. Anything we do in the future will require energy. So Kardashev’s scale classifies potential civilizations, whether alien civilizations out there in the universe or our own, into three levels based on energy consumption. The tiny amount of energy we currently consume pales next to what we leave untapped.
