Sustainable futures using nuclear energy

We present the role of nuclear energy in a sustainable future. This addresses the social, economic and environmental concerns of us all. Nuclear energy today avoids the emission of nearly two billion tonnes of greenhouse gases (GHGs) each year, thanks to over 400 reactors operating worldwide.

Nevertheless, there is no real recognition of real incentives for large-scale non-emitters like nuclear energy and for emissions avoidance in current Kyoto and other policies. These approaches rely heavily on conservation, renewables and efficiency. These measures alone also will not significantly reduce the atmospheric greenhouse burden, because the world is still growing. Also, our (the world's) future economic growth (in all countries) is tied to energy and electricity use. Our prosperity, the alleviation of poverty and the sustainability of the world depend on having a supply of emissions-free and safe energy.

Recent price hikes in fossil fuels and power blackouts also emphasize our need for reliable, safe and cheap power, as is offered by nuclear energy when coupled with effective and secure waste disposal.

A particularly important role for nuclear power in the future will be its links to the hydrogen economy. It is now recognised that the introduction of hydrogen into the transportation sector will benefit the environment only when low carbon sources, such as nuclear reactors, are the primary energy source for hydrogen production. The future could well be the Hydrogen Age. We show that a major reduction in GHGs worldwide can be obtained by nuclear-electric production of hydrogen, thus alleviating their potential effects on future generations. We also demonstrate a potential key synergism with renewable wind power in the hybrid production of distributed hydrogen. Thus, nuclear energy supports and enables the World in its journey to a sustainable, safe and secure energy future.
