Nuclear Power Prevents More Deaths Than It Causes
Climate Change: Study estimates that nuclear energy leads to substantially fewer pollution-related deaths and greenhouse gas emissions compared with fossil-fuel sources
Using nuclear power in place of fossil-fuel energy sources, such as coal, has prevented some 1.8 million air pollution-related deaths globally and could save millions of more lives in coming decades, concludes a study. The researchers also find that nuclear energy prevents emissions of huge quantities of greenhouse gases. These estimates help make the case that policymakers should continue to rely on and expand nuclear power in place of fossil fuels to mitigate climate change, the authors say (Environ. Sci. Technol., DOI: 10.1021/es3051197).
In the wake of the 2011 Fukushima nuclear disaster in Japan, critics of nuclear power have questioned how heavily the world should rely on the energy source, due to possible risks it poses to the environment and human health.
“I was very disturbed by all the negative and in many cases unfounded hysteria regarding nuclear power after the Fukushima accident,” says report coauthor Pushker A. Kharecha, a climate scientist at NASA’s Goddard Institute for Space Studies, in New York.
Working with Goddard’s James E. Hansen, Kharecha set out to explore the benefits of nuclear power. The pair specifically wanted to look at nuclear power’s advantages over fossil fuels in terms of reducing air pollution and greenhouse gas emissions.
Kharecha was surprised to find no broad studies on preventable deaths that could be attributed to nuclear power’s pollution savings. But he did find data from a 2007 study on the average number of deaths per unit of energy generated with fossil fuels and nuclear power (Lancet, DOI: 10.1016/S0140-6736(07)61253-7). These estimates include deaths related to all aspects of each energy source from mining the necessary natural resources to power generation. For example, the data took into account chronic bronchitis among coal miners and air pollution-related conditions among the public, including lung cancer.
