We are not doomed to see the world burn. We know what to do: just build renewables. It is dishonest to claim that using carbon to build them is a problem. The more we build, the less carbon is used on them.

When you need falsehoods to make your case, you have no case.

Falsehood ? What do you know about building windmills ?

I admit that I don't myself know much, but I can tell you that you need at least:

- A modern metallurgy industry using coal to make steal

- Possibly a chemical industry to make composite material

- A logistic industry to move components around the world using petrol (all the solar and wind renewable production is based in china)

- Cement to build your fondation (using gas)

Remove all this and try to build it locally and see how much they cost you...

> A modern metallurgy industry using coal to make steal

Nuclear reactors also require steel (and a chemical industry and cement) but fortunately that doesn't require coal:

Sure but that wasn't the point.

The point is that those that claim that we can replace fossils fuel entirely by wind and solar based on the current price of wind and solar production produced by an industry doped with fossil fuels at every stage are deluding themselves.

It's precisely the point for ALL primary energy sources.

everything is built with the current fossil fuel powered industry. cement, steel, uranium mining and enrichment all is subsidized by the fossil fuel doped industry. Same with wind and solar.

The fact that nuclear power costs more than fossil fuel power is really a reflection that its whole supply chain is consuming more fossil fuel energy than its producing. it is not the magical bullet you think it is.

furthermore, as certain installations of solar and wind are actually producing power cheaper than fossil fuels, its contributing to a trajectory where the % fossil fuels in industry can actually diminish.
