Yesterday, we saw nuclear reactor builders AREVA citing a study that said ‘nuclear power has the smallest land-use footprint of all forms of energy generation’.

The thing is, there’s actually quite a bit of disagreement on the matter. The study ‘Energy Sprawl or Energy Efficiency: Climate Policy Impacts on Natural Habitat for the United States of America’ isn’t the only one to examine the issue.

In his paper ‘Four Nuclear Myths’, Amory B. Lovins, Chairman and Chief Scientist of the Rocky Mountain Institute shows that…

…windpower is far less land-intensive than nuclear power; [solar] photovoltaics spread across land [is] comparable to nuclear if mounted on the ground in average U.S. sites, but much or most of that land… can be shared with lifestock or wildlife, and PVs use no land if mounted on structures, as ~90% now are.

The paper ‘Improving the ecological footprint of nuclear energy: a risk-based lifecycle assessment approach for critical infrastructure systems’ (from the International Journal of Critical Infrastructures, Vol. 1, No. 4.) estimates that nuclear’s land-use footprint is four times higher than coal…

Specifically, a lifecycle assessment of nuclear energy production is important because it captures the release of radionuclides and other toxic materials into the environment... It is concluded that, when critical infrastructure risks are taken into consideration, the actual nuclear footprint may be significantly higher than previous footprint calculations.

Would AREVA care to cite a study taking all this into account?

(And there’s one thing that hasn’t been mentioned: energy efficiency doesn’t use any land at all.)

We’re once again grateful to lumbering French nuclear ogre AREVA’s North American blog for a quite spectacular piece of greenwash, the title of which is...

The Nature Conservancy: Nuclear Power has a Small Footprint

Now, when it comes to environmental issues, what’s the kind of footprint that springs to mind? It would be carbon footprint, wouldn’t it? A quick Google tells us that there are over four million references to ‘carbon footprint’ out there on the internet.

So reading that headline from AREVA’s blog, what kind of footprint did you first think of?

The thing is, the particular footprint AREVA are talking about here isn’t nuclear power’s carbon footprint but it’s ‘land-use footprint’. Apparently, ‘nuclear power has the smallest land-use footprint of all forms of energy generation’. We’ll confess to not being familiar with the term. A quick Google tells us that ‘land-use footprint’ has just over 20 thousand references out there on the internet. It’s not a search term used very frequently at all on Google.

So far, so misleading. It’s just one more example of the creative lengths you have to go to when you want to promote a dirty, dangerous and discredited energy source (debunking nuclear, thanks to it being so dirty, dangerous and discredited, is an altogether simpler proposition).

This isn’t to say that the issue of ‘energy sprawl’ and the amount of land we use to generate our power isn’t hugely important. We’re not downplaying it, it’s just that AREVA is coming to the issue suspiciously late and takes the line that ‘nuclear power has the smallest land-use footprint’ but stays silent on just what happens on the land that nuclear power sits on (in their blog post, they’re still calling nuclear power ‘safe, reliable, clean, CO2-free’ without any proof). It smacks of desperation.

Have the good people at AREVA read this passage of the ‘Land Use Intensity’ study from which they quote so approvingly…?

Our definition of impact varies among energy production techniques, so a less compact way of generating energy does not necessarily mean that an energy production technique is more damaging to biodiversity, but simply that it has a larger spatial area impacted to some degree. Moreover, many energy production techniques actually have multiple effects on biodiversity, which operate at different spatial and temporal scales… Further, the longevity of the impacts described here varies. For example, radioactive nuclear waste will last for millennia, some mine tailings will be toxic for centuries…

In other words, AREVA are promoting the part of the study that says ‘nuclear power has the smallest land-use footprint of all forms of energy generation’ but not the part that talks about nuclear power's devastating impact on the environment from uranium mining to land contamination around nuclear reactors to high-level nuclear waste storage. Fancy that.
