One response to “Editor’s Note to Tom Perriello: Nuclear Power is Not Carbon Neutral nor “Carbon-Constrained””

    Interesting. However, when discussing carbon neutrality, the issues are very slippery. For solar power, the gallium, arsenic compounds, toxic metal wastes, disposal costs, energy consumption during fabrication, etc. must be considered when discussing carbon neutrality. For wind and tidal power, the mining, smelting, and fabrication of the generators are carbon sources, as are the creation of waste metals, plastics, and organic solvents during manufacturing, delivery, installation, maintenance, and disposal. Hydroelectric requires extensive excavations, construction of machinery and structures, and eventual disposal of low level toxics which accumulate in the sediments that pile up behind dams, giving them a finite life span – all resulting in carbon consumption/production. And for coal, the heavy metals and radioactive thorium and uranium components present in each lump of coal must be contained, aside from the mining energy burden, transportation fuel consumption, and waste disposal costs (research the amount of long half life alpha and gamma emitting radioactive materials coming from coal plant smoke stacks – it is in the scientific literature, along with the radiation exposure rates from cigarette smoke, soils and construction materials, etc).

    It is appropriate to detail the cradle-to-grave expenditures and emissions for energy sources, as long as the same comparisons are made for ALL the allegedly green, carbon-neutral energy sources. Even the touch-stone prius required extensive mining and fabrication carbon expenses, and will require expenses over and above that required on non-hybrid cars during disposal of the hazardous materials in their batteries. Even the simple act of burying or cremating human remains adds radioactivity and other waste elements to the planet, along with the carbon dioxide produced during that humans lifetime.

    Carbon is not being created or added to the environment in any of these cases – it is being extracted from one environmental location (coal mines, oil wells, etc), utilized to produce energy at another part of the environment, and finally replaced into a different part of the ecosystem. How and where it is replaced, and the relative efficiencies and appropriate release locations are the issues.
