World Nuclear Association: Carbon Dioxide Emissions From Electricity

https://world-nuclear.org/information-library/energy-and-the-environment/carbon-dioxide-emissions-from-electricity
Updated Thursday, 26 March 2026
  • Over 40% of energy-related carbon dioxide (CO₂) emissions are due to the burning of fossil fuels for electricity generation.

  • All electricity generation technologies emit greenhouse gases at some point in their life-cycle.

  • Nuclear fission does not produce any CO₂. For both nuclear and renewable generation, emissions are produced indirectly, for example during the construction of the plant.

  • Over its life-cycle, nuclear produces about the same amount of CO₂-equivalent emissions per unit of electricity as wind, and about one-third that of solar.


But, CO₂ is not the whole story. As you have reminded us, thermal generation uses great amounts of water (wind and solar do not.)

Cooling Power Plants
Updated Thursday, 1 October 2020
  • The amount of cooling required by any steam-cycle power plant (of a given size) is determined by its thermal efficiency. It has essentially nothing to do with whether it is fuelled by coal, gas or uranium.

  • However, currently operating nuclear plants often do have slightly lower thermal efficiency than coal counterparts of similar age, and coal plants discharge some waste heat with combustion gases, whereas nuclear plants rely on water.

  • Nuclear power plants have greater flexibility in location than coal-fired plants due to fuel logistics, giving them more potential for their siting to be determined by cooling considerations.

The most common types of nuclear power plants use water for cooling in two ways:
  • To convey heat from the reactor core to the steam turbines.

  • To remove and dump surplus heat from this steam circuit. (In any steam/ Rankine cycle plant such as present-day coal and nuclear plants there is a loss of about two-thirds of the energy due to the intrinsic limitations of turning heat into mechanical energy.)



Please, let’s not pretend that renewables are environmental disasters compared to nuclear power plants.

Not that i want to but i have to.

My county gave a huuuuuuuuuge tax break to a fucking data center, which of course is connected to our grid.

The system i'm looking at to get my house off the grid is $20k

...impact of the useless, materially and land intensive wind garbage is low carbon when the wind is blowing, but intense when coal is being burned as it is in Germany and China when the wind isn't blowing. Dunkleflaute lasts in that coal dependent hellhole in Germany for months at a time.

The illiterate reading of what a Rankine cycle is applies to coal and gas plants that kill people when they operate normally in Germany, China, and everywhere on the planet. Of course there is not now and never will be a scientifically illiterate antinuke who cares about fossil fuels.

All one needs to do is to compare the carbon intensity of electricity China, Germany with that of France.

Of course there isn't a single fucking "renewables will save us" antinuke on the whole fucking planet who is interested in attacking fossil fuels, no matter how many times they illiterately pretend to read and care about a Hansen paper and care about its contents.

I have always said that the so called "renewable energy" advocates have zero interest in attacking fossil fuels. QE fucking D.

I don't need to "pretend" that antinukes are pro-coal, pro-gas, pro-petroleum. They demonstrate it every time they open their mouths, particularly with clearly poor reading comprehension skills and readily demonstrated intention to share their weak misinterpretation freely.

Nice try coalie. Nice try. No the word "nice" is not really operative since antinukism kills people, as reported by none other than Hansen and Kharecha.

With decent reading skills, one could look it up.

Have a nice day.

...interpretation of this reading is that the World Nuclear Association is antinuclear?

That is a spectacular demonstration of poor reading skills if so.

I can also tell pretty clearly whether I'm talking to someone who has ever gotten a C or better in an undergraduate science course.

That doesn't matter though. It's pretty obvious.

Speaking of straw men, I kind of always liked the straw character played by Ray Bolger in The Wizard of Oz. He at least was interested in having a brain.

Thanks for the nice demonstration though of where the head of every defender of the disastrous wind and solar industry is and what they're about is. I have always said they have no interest, none, in attacking fossil fuels.QED.

Yesterday the concentration of the dangerous fossil fuel waste carbon dioxide in the planetary atmosphere was registered at the Mauna Loa Observatory was 432.48 ppm, tied with that of April 1st of this year for the 3rd highest daily reading ever recorded after 432.68 ppm on March 31st, 2026, second highest, and April 5th, 2026, 433.24 ppm the absolute highest ever recorded there.

I'm sure in the antinuke community which pushed for the 5.6 trillion dollars squandered on solar and wind junk, they're all encouraged by and very proud of these numbers. (When aI joined DU 22 years ago to first listen to antinuke pablum, the number was 372.94 ppm)

Congratulations I guess. You must be very, very proud.

I look forward to another whiny misreading of a Hansen paper that spits on his scientifically inspired efforts in support of nuclear energy .

If I were made of straw, I'd work on my reading skills in the manner Ray Bolger might have done.
