Title: Clean Wind Power
1Clean Wind Power in New Jersey
2Clean Energy in New Jersey is Important to meet
Environmental Needs
- Fossil Fuel derived energy contributes to
- Global Warming / Air Pollution
- Local Air Quality Problems
- External Effects
3Focus Pollution and Birds
- "Neotropical migratory birds are important for
our ecosystems. They work as nature's pest
controllers and pollinators and provide many
hours of enjoyment for birdwatchers and outdoor
enthusiasts. " (Secretary Gail Norton 6/9/04
USFW press release)
4- Importance of Birds
- Insect control and pollination
- Seed dispersal
- Enjoyment- in 2001 wildlife watchers spent 1.23
Billion in New Jersey (USFWS). - Changes in weather mark the initiation of
migration.
5Global warming threatens to create shifts in
vegetative communities and regional climatic
patterns.
- These changes could greatly disrupt migratory
birds if the plants they depend on for food
become absent in a region, flower or fruit
earlier or later due to climatic changes. - A study of 35 North American warblers found that
the range of seven species have shifted northward
an average of gt 65 miles over the past 24 years,
while none of the 35 species shifted southward
(Price and Root, unpubl. data in Price and Glick
2002).
6- Scientists have discovered behavioral changes in
birds that correspond with warming spring
temperatures, resulting in earlier migration. - Changes in migration chronology could have
devastating consequences for some birds. - Birds that are associated with very specialized
habitat types are very vulnerable to climatic
shifts because such shifts may eliminate their
habitats. (Both and Visser 2000). These include
Black-throated Blue Warbler, Golden-winged
Warbler, Chestnut-sided Warbler, Blackburnian
Warbler, and Rose-breasted Grosbeak (Price 2002).
7Pollution can have other effects on ecological
communities
- Concentrations of air pollutants common in many
areas of the United States can alter vegetational
communities. - Leaching of calcium from the soil by acid rain
may be having a negative impact on the nesting
success of species dependent on environmental
calcium for egg laying (Hames et al. 2002). - Changing of ecosystem structure will likely cause
an impact on avian, and other wildlife,
populations.
8POINT Green Matters! Increased use of clean
energy is needed to protect the ecological health
of our environment.
- Potential Solution
- The effects of global warming will need to be
ameliorated through changes to rules governing
emissions, and incentives for increased fuel
efficiency, energy conservation, and renewable
energy.
9Wind Energy is Compatible with Ecology
Sticking with birds
- A major environmental concern with the locating
and development of wind turbines or wind power
farms is the impact the facilities may have on
bird (and bat) populations.
10Is avian species mortality really an issue? -
Yes
- Wind derived electricity now represents only
small component of the total electric produced in
the U.S. (0.3?), but growing rapidly. - Today's utility-scale wind turbines can be quite
large blades 130' in length, total heights of
400'. See the web site for the American Wind
Energy Association for background data on wind
plant operations http//www.awea.org. - Any structure has the potential to harm birds.
It has been estimated that communication towers
kill up to 50 million birds a year, 90 of which
are neotropical migratory birds. Tall-building
collisions (office buildings) kill millions of
birds each year.
11- Wind turbines impact birds through
- i) collisions with the turbine blades, towers,
power lines, or with other related - structures
- ii) Turbulence / wind shear
- iii) habitat impacts (the infrastructure)
- Recent information from U.S. projects indicates
that bird mortality at wind turbine projects
varies from less than one bird/turbine/year to as
high as 7.5 birds/per turbine/year.
12The numbers of fatalities add up quickly.
- The Mountaineer Wind Energy Project in West
Virginia, a wind farm of 44 large turbines and
related structures, is believed to have caused an
estimated mortality of 4.80 birds per turbine in
2003 (211 birds). - The National Wind Coordinating Committee reported
that the annual estimate of all avian mortality
from the 15,000 operational wind turbines in the
U.S. in 2001 was 10,000 to 40,000 birds. See the
National Wind Coordinating Councils web site at
www.nationalwind.org. - Poor planning could conspire to cause significant
mortality. One calculation for a proposed 180
turbine facility calculates a potential for
15,000 bird/bat kills per year at that site
alone. - Add to this the cumulative effect on migrating
populations as they move across multiple wind
farms, and population impacts become an issue.
13POINT
- Development and implementation of wind-power
facilities have the potential to cause
significant harm to avian species, and so to
ecological systems in general
14POINT CONTINUED BUT IT DOES NOT HAVE TOO.
15Can we develop ecologically friendly wind power?
Very Likely YES
- Prior to constructing wind power projects, the
potential risks to birds and bats can be
evaluated. - Pre-construction, a proper siting analysis can be
done for each new wind turbine farm. - Sites known to be used by rare birds could be
avoided, as could known heavy migration pathways,
or landscape features known to attract large
numbers of birds. - Lighting could be minimized.
16What Are We Doing About All This?
- Power industry, wind industry, private parties,
NGO's and government agencies are collaborating
to design policies and guidelines to implement
wind power in an ecologically friendly way.
17Bottom Line
- We believe that by engaging in open dialogue
with commercial interests and regulators, and by
carrying out research on potential impacts and
impact avoidance in the mid-Atlantic flyway, we
will likely be able to implement much needed,
commercially viable, technologically feasible,
and ecologically friendly wind energy in New
Jersey.
