The city council of town X proposes
that since LED lights burn brighter and cost no more to purchase,
switching to them gradually over time will help town X save money on
electrical costs in the future. On its face this seems like a good
plan, however additional questions could help evaluate the efficacy
of the council's prediction.
The most prescient question to ask is
whether or not LED lightbulbs actually use less electricity. If LED
bulbs do use less energy, and their total cost of use, including the
purchase and disposal price, is indeed less, than the total cost of
use of incandescent bulbs, the council's prediction will be
strengthened. The city council could consult scientific studies
measuring LED bulb electrical use as compared to that of incandescent
bulbs fairly easily.
However, there are other cogent
logicistical questions to address as well, including about the
specifics of which lightbulbs will be replaced with LED bulbs. Will
the light fixtures in city X be compatible with LED lightbulbs, or
will they need to be replaced as well? What are the specific wattage
requirements of the new bulbs, and will they even fit inside of the
old fixtures designed for incandescent bulbs? Are there LED bulbs
designed for every fixture? If not, will the lack of uniformity in
the lighting of public buildings be a concern to those that need to
use those buildings? How many LED incompatible light fixtures would
make it better for incandescent bulbs to be used? If some of the
fixtures are incompatible, the council's prediction would be weakened
because there would be less potential for savings in electrical
costs.
The city council of town X should also
consider how expensive electrical costs are to begin with. Are there
significant savings to be had from reducing electrical costs, or are
the costs already so low that any savings will end up producing a
relatively minimal effect? The council should also consider the rate
of change of electrical costs. If electrical costs are decreasing
over time, the potential for savings will be less and the council's
prediction will be weakened. If electrical costs are increasing
exponentially over time and LED lights cost less to operate, the
council's prediction that they will save money will be strenghtened.
The city council of town X should
consider what the broader effects of switching to LED bulbs might
have, and whether they will incur unforeseen costs in productivity,
reducing the potential savings overall. For example, how will the
quality of light of LED bulbs be different from that of incandescent
bulbs? Is brightness the only factor at play, or do LED lights
transmit a different quality (temperature, warmth) of light? Do the
LED lights in question take longer to light up and off? If so, how
will these qualities effect the efficiency and productivity of the
people who will be working around them? Will they be able to see what
they need to see in order to effectively complete their work? The
council's prediction about saving money overall through this switch
could be weakened if LED lights will have serious negative effects on
the people who need to use them.
The city council should also consider
the entire operation cost of LED bulbs rather than merely their cost
to purchase. Is the cost of installation and disposal of LED
lightbulbs different from incandescent bulbs? If these operational
costs are greater than that of the status quo, the council's
prediction will be weakened.
The council might also choose to
consider the greater operational costs that extend beyond the
community of town X; what are the production costs of LED bulbs and
how do they differ between that of incandescent bulbs? Are there
difficult to measure costs such environmental pollution/impact that
might occur during both the production and disposal processes of LED
bulbs? If these are real costs, though they might reduct the city's
electrical expenses, perhaps the greater cost might be a factor in
the council's final decision.
In conclusion, the assessment of the
cost of LED bulbs being the same purchase price as incandescent bulbs
is not a solid enough basis for the city council of town X to make
the decision to make this switch because a variety of factors are at
play that could effect the overall electrical costs. If the council
wants to prove that LED lights would decrease costs, they should
further investigate the electrical costs themselves, the overall cost
and effects on workers to operate LED bulbs, as well as the basic
scientific facts behind the electrical use of the bulbs.

I feel really good about this essay. It's totally solid, does exactly what the instructions said to do, picks apart the problems, and there were not really any significant grammar or spelling errors (a few very small ones). I would give myself a solid A on this.
