>Some estimate we're currently only at Kardashev 0.8, harnessing about 80% of what energy from the Sun hits the Earth.
80% seems super high, unless by 'harnessing' you also mean things like 'the sun energy warms up the ocean allowing fish to live which we then consume for some% of the energy that sun sent'.
I'd be pretty surprised if efficiently used energy / energy hitting the earth from the sun was >20%.
