This piece extends the debate over the potential of nuclear energy, as the question of whether nuclear power can provide a big part of the worlds energy needs is extremely important in our energy future — it is the only alternative energy source beside coal providing the type of electricity production necessary for the current electric grid model: big, base-load capable power plants. If that role is fulfilled, the current electricity production system can continue beyond Peak Oil, and even expand to provide the energy necessary for electrified transport. If it falls short, a new energy model is needed.
