This post was borne out of a debate in the comments section of my last post. You can find that exchange here.
Using nuclear to fight climate change is replacing one environmental
problem (fossil fuel electricity generation) with another. In 2006 the
Pembina Institute (arguably Canada's most respected environmental think
tank) released a comprehensive, 130 page analysis
of the environmental impacts of nuclear power generation in Canada.
It's team of engineers, eco-efficiency analysts and policy analysts
found that nuclear energy should not be considered a solution (or even
part of the solution) to climate change.
Here is an excerpt that sums up their arguments well:
while
the GHG emissions associated with nuclear power are less than those
that would be associated with conventional fossil fuel energy use, no
other energy source combines the generation of conventional pollutants
and waste streams (including heavy metals, smog, and acid rain
precursors, and water contaminants) with the generation of extremely
large volumes of radioactive wastes that will require care and
management over hundreds of thousands of years. The combination of
these environmental challenges, along with security, accident and
weapons proliferation risks that are simply not shared by any other
energy source, place nuclear in a unique category relative to all other
energy supply options. In essence, reliance on nuclear power
as a response to climate change would involve trading one
problem-greenhouse gas emissions-for which a wide range of other
solutions exist, for a series of other complex and difficult problems
for which solutions are generally more costly and difficult and for
which the outcomes are much less certain.
If nuclear is our answer to climate change, why is every major Canadian environmental organization against
it? It's not a sustainable long-term solution and it's not emissions free. In fact the amount of GHG emissions generated by nuclear power-related activity has been estimated to be just under 600 000 tons a year in Canada. That's about the equivalent of putting 170 000 new cars on the road for a year. Nuclear power is dirty and its proliferation only
takes interest and resources away from the development of renewable
energy and the promotion of energy conservation. It puts money in the
pockets of a few (in the short term) and it does nothing to foster a
sustainable energy future for our province or country.
