But I think our energy consumption is miniscule on the scale of energy received from the Sun.

I did the math once, and a square of 300x300km of solar panels in the Sahara would cover all the world electricity demands.

The issue is with green house gases, cutting forests which alter the way Earth handles Sun's light, not out actual heat output which is minuscule compared to the heat of planet Earth.

I believe Elon came up with similar figures during his Powerwall presentation, along with how small of an area it would be to provide the batteries to complement the solar panels.

"300x300km of solar panels should be enough for everybody"

Joking aside, much like with memory, bandwidth and storage, we'll invent ways to use (all of the) energy if it is cheap enough.
