No, I dont think, I KNOW.

Quite misleading, but that is true of many of the sources you quote.

That article calculates the future need for nuclear plants on the basis
of the current output of 440 operational reactors, completely ignoring
the fact that only about 150 of those have outputs in excess of 1,000
MW, while a single modern station could have an output of nearly
6,000 MW.

Still a lot of reactors.

Nowhere near as many as they try to suggest and needing a lot less or
either land area (1) or raw materials (2) than renewables.

(1) Per 1000 MWe:

Solar PV: 20-50 km^2
Wind: 50-150 km^2
Nuclear: 1-4 km^2


(2) Per MWe of *installed* capacity. The figures in parenthesis are the
multipliers that must be applied to get the materials requirements for
an actual output, allowing for typical capacity factors:

Solar PV: 40 t steel, 19 t aluminium, 76 t concrete, 85 t glass, 13 t
silicon. (7 Spain to 15 Glasgow)

Since the typical 250w panel only weighs about 16 kg where does all the
glass go?

40t of steel is a lot of nuts and bolts which is about the only place
its used.


Wind: 118 t steel, 298 t concrete. (3 to 4)

A large amount of oil is needed to make the plastics used in wind
turbines isn't it? There is a fair amount of glass in the resin too.

I wonder if the bases will be reusable or will they have to be dug up
and recycled or landfilled?


Nuclear: 36-40 t steel, 75-90 m3 concrete. (1.25)


Largely untried technology too.

Completely proven technology that is the safest method of power
generation, by far.

A bit like hydro was proven technology until they discovered just how
damaging it is to nature.
I expect they knew how bad it is but decided to hide the facts.
