> Why does it matter how much electrical energy it uses? We know how to harness a near infinite amount.

This is a silly thing to say while there's still quite so much CO2 being emitted from electricity production.

I suspect the OP means solar and wind. It’s a fair point given that these have batteries, and could easily swap them out for precharged ones.

Care to share this infinite energy idea?

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.

I still don't know, I'm sorry.

Because it claims to be green, and you'd need a green way to harness that amount on demand.

Are you aware of how inefficient our current solar panels are?
