In most of our discussions about energy, we all seem to be die-hard supply-siders. We focus most of our attention on how to obtain more energy and very little on how to make better use of what we have.
It is difficult to know how much energy we waste in the
United States. Information provided by
the Department of Energy[1] and Lawrence Livermore labs[2]
has been used to argue that we waste more than half of the energy we use. That may
an overstatement since conversion and transmission of energy inevitably lead to
some loss.
Nevertheless, we do use an extraordinary amount of energy,
and much of it is unnecessary. In 2009, the U.S. consumed 9.4 quadrillion BTUs
of energy.[3] That is enough energy to heat all of the water in the
Atlantic Ocean by more than half a degree.[4] We also know that the U.S. uses more than
twice as much energy per person as does the European Union and more than four
times as much as the world average.[5]
We spend a lot of time, money and effort trying to find
clean and renewable ways to produce energy, and we should. However, it appears unlikely that any of
these will be game changers in the near future.
We wring our hands about energy independence, engage in wars
over energy resources, and support horrible governments to get access to their
oil. We dig in places that would be better left undisturbed. We pollute our
environment with the byproducts of burning unbelievable amounts of fossil
fuels. We flirt with unimaginable disasters by using nuclear energy. We extract oil from sources like tar sands that
are known to be environmentally damaging.
We extract natural gas using fracking techniques that pump thousands of
gallons of toxic chemicals into our underground aquifers and may increase the
odds of earth quakes. And all the time
the real payoff is simply to quit wasting energy. Conservation doesn’t mean
sitting at home in the dark with your coat on. It simply means stopping the
flow of energy that isn’t needed.
The opportunities are everywhere and include insulation,
smart lights, smart power grids, black pipes on roofs to heat water, heat
pumps, high mileage vehicles, goods shipped by train rather than truck,
passengers moved by train or bus rather than by plane or car, high efficiency
furnaces and air conditioners, and smart buildings. The opportunities are
almost endless, and the government can have an enormous impact on facilitating
their implementation by providing incentives and assistance. Doing so will
create jobs, increase our quality of life, reduce pollution, improve
international relations, and improve our business climate.
Conservation may not be as cool as some sexy new technology,
but it sure makes a lot of sense.
