now because of the way we make energy

Idiotic statement!

We do not make "energy" in any way, shape, or form! God made all the energy that exists at the instant of creation. It is all the energy that ever was, now is, and ever will be.

We convert energy from one form to another to suit our purposes. Every time we make such a conversion we rely on a difference of potential to extract some of the energy (in a differing form) to power our lifestyle with a bit of the original energy "lost" (it appears as an increase in entropy). Think about energy in it's various forms. Potential energy flows "downhill" (an avalanche falls from a mountain into the valley below, never the other way!). Water flows downhill (same!). Electricity flows from a high voltage (potential) to a lower (ground). Heat flows from a higher temperature to a lower temperature.

You may pump water uphill, rocks may be conveyed to higher ground, you may charge a capacitor to a high voltage, and you may "pump" heat from inside your house to the outside with an air conditioner. It is the "hills and valleys" in the potential fields that allow us to extract energy. In every one of these reversals of the normal flow of energy, some energy is lost and remains unavailable.

That loss represents entropy. Think of it as a gradual lowering of the "potential" to use energy. The valley gradually fills so avalanches can no longer fall. In like manner all potential fields (electrical, gravitational, thermal) become flatter as time goes forward. It is the "hills and valleys" in the potential fields that allow us to extract energy.

One further note; Increasing entropy can be visualized as an arrow that points in the direction of the future. It thus defines time as increasing entropy. When all potential fields have flattened out, entropy can no longer increase and thus time stops. All of the energy originally put into our universe is still there but it is no longer available to us inside the universe. We can no longer reach it to use for our purposes.

Yep. That was the whole point of his piece.

The whole idea that homosapiens on a a tiny planet in our Solar System in the Milky Way galaxy can control the temperature of a planet in the Universe doesn’t even pass the laugh test.

You know what they say about a big lie...
