Should nuclear energy be part of Australia’s (and many other countries’) future energy mix? We think so, particularly as part of a solution to reduce greenhouse gas emissions and prevent dangerous climate change.
But there are other reasons for supporting nuclear technology. In a paper recently published in Conservation Biology, we show that an energy mix including nuclear power has lowest impact on wildlife and ecosystems — which is what we need given the dire state of the world’s biodiversity.
In response, we have gathered signatures of 70 leading conservation scientists from 14 countries in an open letter asking that the environmental community:
weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is ‘green’.
Energy demand is rising
Modern society is a ceaseless consumer of energy, and growing demand won’t stop any time soon, even under the most optimistic energy-efficiency scenario.
Although it goes without saying that we must continue to improve energy efficiency in the developed world, the momentum of population growth and rising living standards, particularly in the developing world, means we will continue to need more energy for decades to come. No amount of wishful thinking for reduced demand will change that.
But which are the best forms of energy to supply the world, and not add to the biodiversity crisis?
Assessing our energy options
In short, the argument goes like this.
To avoid the worst ravages of climate change, we have to decarbonise fully (eliminate net carbon emissions from) the global electricity sector. Wildlife and ecosystems are threatened by this climate disruption, largely caused by fossil-fuel derived emissions.
But they are also imperilled by land transformation (i.e., habitat loss) caused in part by other energy sources, such as flooded areas (usually forests) for hydro-electricity and all the associated road development this entails, agricultural areas needed for biofuels, and large spaces needed for wind and solar farms.
