High gas prices and a concerted effort to curb global
warming are breathing new life into the wind industry.
About 2,500 megawatts of wind power have been added to the
United States' generation mix in the last 12 months, which
equates to roughly 9,200 megawatts of total generating
wind capacity here.

Nations around the globe are taking action to diversify
their energy mixes and to cut harmful emissions. Beyond
that, specific industries are finding out that such
environmental strategies are good for business: Companies
are relying more on alternative fuel sources that cut
their energy use and subsequent overhead as well as their
carbon dioxide output. DuPont, for example, has reduced
its emissions by 40 percent -- between 1990 and 2000
levels by using such techniques as re-using steam heat.
Meanwhile, it's producing goods at a 30 percent faster
rate.
Wind is one of the beneficiaries of these new dynamics.
The growth in wind power construction comes at a time when
customers across the country are facing electricity and
natural gas rate hikes because of the natural gas supply
shortage, with 2005-2006 winter gas prices projected at
$10-13 per million BTUs compared to last year's average
prices of $5-7 per million BTUs. Wind power, which
generates energy without using fuel, provides a hedge
against rising energy costs because wind energy production
is immune from fuel price spikes.
"The market forces are now in place," says Tom
Matthews, president of US Wind Force in Pittsburgh. "By
that I mean the numerous mandates that have been passed in
the Mid Atlantic region and in New England. The tax credit
has also been extended through 2007. Most of the
opposition with regard to wind energy is NIMBY -- not in
my backyard -- related. The vast majority support
renewable energy, particularly wind that is 100 percent
emission free."
Certainly, wind is still a small component of the
nation's energy mix, producing less than one percent of
all electricity here. Still, the American Wind Energy
Association estimates that an installed capacity of 9,200
MW of wind power will save over half a billion cubic feet
of natural gas per day in 2006, alleviating a portion of
the supply pressure that is now facing the natural gas
industry and is driving prices upward. The U.S. currently
burns about 13 billion cubic feet per day of natural gas
for electricity generation, which means that by the end of
the year wind power will be reducing natural gas use for
power generation by 4-5 percent.
Wind power plants can be permitted and built in one to
two years, whereas the drilling of new natural gas fields
and the construction of Liquefied Natural Gas terminals
takes much longer. The wind association projects that more
than 14,000 megawatts of wind capacity could be part of
the nation's generation supply by the end of 2007,
producing the equivalent of .85 billion cubic feet per day
of natural gas.
Rapid Growth
Wind is also riding high because it does not contribute
to the nation's environmental problems. Burning fossil
fuels for electricity generation causes over a third of
the greenhouse gas emissions in the country, as well as
more than two-thirds of the emissions that cause acid
rain, and one-third of the emissions that cause smog.
"Wind power's rapid growth provides what is potentially
the quickest and best supply-side option to ease the
natural gas shortage," says Randall Swisher, executive
director of the wind association. "We are hopeful that the
momentum started in this record-breaking year will
continue because of the Congress's foresight in extending
the wind energy production tax credit through December 31,
2007. The wind power industry is stepping up to provide
the U.S. with a significant amount of its power needs in
this time of uncertainty."
To be sure, the wind industry faces many challenges.
The wind, for example, does not blow on demand and it
generally cannot be economically stored. That's why wind
farms must be backed up by conventional power plants to
ensure that electricity will be available when needed.
That duplication of capacity not only diminishes the
environmental benefits of wind, critics say, but it also
increases the cost of wind power while adding an extra
burden on the transmission system, although federal
regulators have acted to make it easier for wind units to
connect to the grid.
And then there's the issue of birds and bats running
into the windmills and dying. It's created a bit of an
uproar, although the Government Accountability Office
released a study on the environmental impacts of wind
energy that found that it is not a significant source of
bird deaths, especially when viewed in context with other,
much more deadly sources of bird mortality like plate
glass. "No fuel supply and no form of energy are without
consequences," says Frank Maisano, spokesman for a
coalition of wind developers in the Mid Atlantic region.
Wind farms, meantime, are generally more expensive to
build than fossil-fueled generation. The U.S. Department
of Energy says that roughly 80 percent of the cost of wind
projects is the machinery, with the balance being site
preparation. And with today's steel prices at least 50
percent more than last year, constructing a wind farm is a
costly endeavor. Still, once a wind farm is built, the
price of the power is stable. Further, with the current
subsidy, it is also cost competitive.
Critics of wind power, however, say that the tax breaks
and subsidies are paid for by taxpayers and electricity
customers. MidAmerican Energy, for example, is scheduled
to complete by year-end a 310 megawatt wind farm in Iowa
-- a plant it acknowledges would not have been built had
it not been for the production tax credit. "Every other
form of power generation is subsidized in some manner,"
says Matthews, with Wind Force.
Good Value
Capital, of course, flows to where it is naturally most
welcome and where investors can earn reasonable returns.
Along those lines, Siemens AG says that it sees a 10
percent growth in the wind energy market and notes that it
plans to invest primarily in China, Europe, India and the
United States. The hope is that major players such as
Siemens and GE Energy will facilitate further development
by making modern technologies more accessible to the
utilities that would use them.
"People will pay more for green energy and I wouldn't
underestimate the value of these projects in the market,"
says Barry Abramson, a Wall Street analyst with Gabelli
Utilities Fund. Puget Sound Energy, for example, says that
wind power is the best value.
The confluence of more government attention with
general demand in the market for greater efficiencies,
reduced energy costs and a cleaner environment have joined
to give wind energy a boost. While wind is a relatively
minor component of the nation's energy mix, it is expected
to gain a higher profile. And with energy consumption
expected to rise about two percent annually for the
foreseeable future, the nation needs all the fuel supply
it can get.
