First, the author's projection for flat or declining total demand for electricity ignores business
and commercial electricity usage. It is entirely possible that area businesses will increase their
use of electricity in the future and that total electricity consumption will actually increase
despite flat or declining residential demand. The author's projection also ignores the possibility
that the number of area residents will increase in the future, thereby resulting in an increase in
electricity usage regardless of whether more efficient appliances are used in area homes.
Without taking into account these possibilities, the author cannot persuade me that total
demand for electricity will not increase in the future.
Secondly, the author's conclusion relies on the assumption that area residents will actually
purchase and install the energy-saving appliances and systems the author describes.
Admittedly, the author points out that homeowners are "eager to conserve energy."
Nevertheless, these homeowners might not be able to afford these new systems and
appliances. Moreover, the energy-efficient insulation that the author mentions might be
available only for new home construction, or it might be a gas system. In either case, the mere
availability of this system might have no effect on total electric usage in existing homes.
A final problem involves the assertion that no new electric power plants are needed because
the three existing plants, which are 20 years old, have always been adequate for the area's
electric needs. The author fails to account for the possibility that the old plants are themselves
less energy efficient than a new plant using new technology would be, or that the old plants
need to be replaced due to their age, or for some other reason. Besides, this assertion ignores
the possible influx of residents or businesses in the future, thereby increasing the demand for
electricity beyond what the three existing plants can meet.
