    T here are several reasons why I think demand-side manage- ment programs are likely to grow

    over the next couple of decades.

    One is the increased emphasis on

    integrated resource planning,

    which recognizes conservation

    and load management as re-

    sources equivalent to and substi-

    tutable for power plants. The sec-

    ond is environmental concerns,

    including global warming. The

    third is financial incentives, which

    Harrison Wellford and Earle Tay-

    lor also mentioned. Last is a

    growing recognition that utilities

    can play an important role in over-

    coming the market barriers that

    stand between Amory Lovins

    I developed a very simple

    spreadsheet model at Oak Ridge

    National Laboratory and used it

    to simulate the effects of an ambi-

    tious scenario of demand-side

    management programs over the

    next 20 years. My results are sum-

    marized in Figure 1. The top curve is the forecast from the En-

    ergy Information Administration,

    which EIA developed for the De-

    partment of Energys National En-

    ergy Strategy. The bottom curve

    is my forecast, which shows how

    much electricity consumption

    could be reduced with aggressive

    DSM programs. This amounts to

    about a 20% reduction by 2010, Table 1: Ambitious DSM Programs

    consistent with the estimates Reduction in electricity use

    made by a number of utilities from DSM in year 2CKKl

    which are conducting aggressive Southern California Edison 13% DSM programs (see Table 1). Long Island Lighting 9%

    Some other beneficial effects of Consolidated Edison 6%

    ambitious DSM programs include: Seattle Cii tight 7% Northeast Utilities 7%

    This all sounds wonderful. But A part of documentation is the
