Elon Musk reveals why, measured against the sun's energy, human civilization barely registers as existing at all: "Right now we're very low on the Kardashev one scale. If you say what proportion of our planet's power are we harnessing, it's a very, very tiny number. And we're harnessing almost nothing of our star's power. The sun is truly an immense thing. It's difficult with words to characterize just how immense the sun is" "The sun is about 99.86% of all mass in the solar system. Most of the remaining 0.14% is Jupiter. The entire mass of Earth is in the tiny miscellaneous category. Earth is a tiny dust mote compared to the sun" "We currently use much less than a trillionth of the power output of the sun, and a trillion is a million times a million. So basically we're practically nowhere on the Kardashev two scale. On the Kardashev scale, we're still non-existent. We're not registering"
