24   Nanotechnology as a Tool for Sustainability

        Increasingly, the primary energy producers that put electrical power in
        the world can simply dump the power onto the grid in the cheapest pos-
        sible way, and locally, the local storage buys it off the grid when it is
        cheapest, when it is, of course, most abundant. Such a system would
        relieve the pressures of having to provide almost twice the generating
        capacity than is used on average to account for the peaks and the lows
        of electricity demand. Competition at the residential storage appliance
        level allows the electrical energy grid to transform itself, with a time
        period of a couple of years rather than decades. By allowing the possi-
        bility to mix locally produced electricity with grid-delivered centralized
        sources, the energy system becomes more robust.
          The shift to a nanosupported, localized distributed energy system has
        the advantage that it does not require tearing down existing centralized
        facilities and building completely new and separate infrastructure. New
        distributed facilities can be initiated now and connected to the existing
        plants providing power to the grid. The value is that it would facilitate
        not only residential solar, but also other very remote energy sources to
        this same grid, including vast solar farms in the deserts, where local
        storage serves as a buffer supply for when the sun is down, as well as
        storing energy from wind when it is blowing. Vast amounts of electrical
        power can also be imported from remote nuclear power sources way out
        in somebody else’s backyard, behind a military fence, where one can be
        absolutely sure there is no nuclear weapons risk or accident risk asso-
        ciated with plant operations. Links are also possible to electricity plants
        generating power from clean coal, wherever there is a site where CO 2
        can be sequestered cheaply and not have it come back at greater than
        0.1 percent leakage per year. Distributed electricity systems can be used
        to fuel plug-in electric hybrid vehicles.


        Conclusion
        Our current energy predicament requires a bold new energy science
        and technology program, as well as an enlightened federal policy to
        map out the path to development of new sources for a better energy and
                                      st
        environmental future for the 21 century. Such a path will have to be
        guided by an enlightened federal energy policy that goes well beyond
        anything we have had or have today. Elements of a new energy policy
        must include the means and incentives to rapidly develop, demonstrate,
        and deploy cheaper, more efficient, and environmentally sound energy
        supplies to protect the global environment while improving the quality
        of life in developing countries. With visionary leadership at the highest
        levels of government—and sound national science, technology, and
        energy policies to match—larger numbers of talented and motivated
