The myth of clean energy
The mantra of the Greens is that we, the United States,
and the other industrial powers are destroying the earth with our excessive use
of fossil fuels.
As early as 2003, Alan Caruba
wrote (CNSNews.com Commentary): “We need to understand that we cannot
‘conserve’ our way to energy use.
“Untapped energy resources are wasted energy … there are
ways to reduce energy consumption, but the issue is not consumption so much as
it being able to have energy when you need it. Energy literally fuels the
engine of the American economy — and your home or apartment, your workplace,
your car, etc.”
So, if conservation is not the answer, what other
alternatives are there – and are they clean?
The focus of environmentalists, led by the Sierra Club, is
on renewable energy sources: biofuels, biomass,
geothermal, hydro power, solar power, tidal power, wave
and wind power. These include energy that is derived from photovoltaic power
plants, and ethanol for transportation.
“About 13 percent of the world’s primary energy comes from
renewable sources, with most of the renewable energy coming from traditional
biomass, like wood-burning.
Hydropower is the next largest renewable source, providing
two to three percent and modern technologies, like geothermal, wind, solar, and
marine power together produce less than one percent of total world energy
demand.” (Wikipedia, “Renewable Energy”)
Unfortunately, these sources of energy, as promising as
they may be, do not yet come close to meeting the world’s needs with clean
energy.
Biomass fuels must be grown, collected, dried, fermented
and burned, all of which must have resources and an infrastructure.
Ethanol has been reported to take more energy to produce
than the final product provides. Another biofuel is
wood.
However, burning wood produces serious pollution. In
Denver, for example, the use of wood burning stoves is highly regulated: “… a
‘red’ advisory makes it a crime, and ‘violators who burn without approved
low-emitting stoves or inserts can be fined as much as $15,000 a day.’” (The
Denver Post, “Winter air-quality alert puts damper on
wood burning today,” by Steve Lipsher)
Hydroelectric power requires large dams, such as the Grand
Coulee Dam in Washington State.
The possibility of undertaking such projects in America is
now extremely doubtful. Environmental laws and activism would block them or
cause delays that would drive up costs to the point that they would not be
feasible.
Writing in the Washington Times, Robert J. Samuelson
noted, “… in effect, natural gas powers the Internet and most PCs. It is also a
major fuel for manufacturers and for heating office buildings.
“In 2002 about half of gas sales went to industrial and
commercial users. The trouble is that we’re no longer self-sufficient in
natural gas — and our import dependence will grow. … The hallmark of U.S.
energy policy is a steadfast refusal to confront choices.”
One thing is for certain: energy is not free, no matter
what the source. It’s also necessary to consider the cost of developing and
delivering the energy we need, along with the potential of harmful byproducts
or waste.
In the final analysis, clean or not, we need energy
sources that can power our industrial society with the least amount of harm to
the environment at the lowest possible cost.
Whatever route we
go, it will not be free and it will not be clean in the sense that it produces
zero waste or zero damage to the environment.
