Could you please name the technology? I work with renewable energy and I have no idea. Are you talking about nuclear?

  Ancestor comment is probably daydreaming about being in a Kardashev 2 civilization with a full Dyson Swarm collecting 100% of the Sun's total energy output, in all directions. Some estimate we're currently only at Kardashev 0.8, harnessing about 80% of what energy from the Sun hits the Earth, while others argue that this percentage is much lower. Ideas are easy, implementation is hard. Edit for clarity.

    >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%.

    We aren't in the same universe as 80% of the Sun's energy that hits Earth being used. The numbers I'm seeing are 174 petawatts hits Earth and the world uses 18 terawatts of energy.
