Pantego Wind Farm

Conserve NC is a supporter of alternatives to fossil fuel, including wind energy. We recognize that one of the limitations of wind energy is the environmental consequences of improper siting, particularly the effect on wildlife.

One example of bad wind farm siting is the proposed Pantego wind farm in Beauford County in eastern NC. This is a proposed 80MW wind farm that is to be located near the Pongo lake area of the Pocosin Lakes National Wildlife Refuge. Pantego Wind Energy LLC has asked for a Certificate of Public Convenience and Necessity from the NC Utilities Commission.

Wind Power

ConserveNC supports the development of wind power when the wind turbine sites will not adversely affect either people or wildlife. One of the major problems of wind energy is the fact that improperly sited wind turbines can kill birds and bats or disrupt the habitat of wildlife.

Certain locations off the shore of NC are not used by birds or other wildlife that would be disrupted by wind turbines. These areas also have relatively strong and steady wind and will supply a large amount of energy. They should be used.

In future posts, we will comment about wind power, particularly off shore wind power. So stay tuned.

Wind Power

One issue that divides the environment community is wind power. We need more renewable energy to replace the use of coal. On that almost everyone agrees. One source of renewable energy is wind power. However, there are serious environment consequences to the use of wind turbines.

The most well known and discussed problem is bird strikes, when the blade of a turbine strikes a bird. While that remains a problem, particularly in areas where bird migration paths will cross a line of wind turbines, it is much less of a problem than before because modern wind turbines are designed to use slower turning blades, and the structures do not have parts that would allow birds to perch.

A less well known and studied problem is the effect on bird habitat. One of the most attractive locations for wind turbines is mountain ridges in the western mountains of NC. However, many of these same ridges are used by raptors and other birds which make use of the updrafts to soar along the ridge looking for food. Much more needs to be learned about the effect of the wind turbines on these birds. Will they coexist with the turbines or will they seek other areas for their soaring and hunting.

Another area that has the sufficient wind is the coastal sound area of eastern NC. However, it is also an important area for birds. There are birds that fish in some areas of the sounds and roost on shore nearby. If a line of wind turbines is between the fishing area and the roosting area, the birds may move to a different, less desirable, area. Again, this needs more study before we allow wind turbines in our sound areas.

We do need more renewable energy. However, it is estimated that, fully developed, wind turbines in the mountain areas will produce only 800 MW of power when the wind is blowing. That much power will require at least 400 wind turbines. And the wind doesn’t always blow, even in the mountains. By comparison, some of the newer coal fired power plants produce over 2,000 MW, even when the wind doesn’t blow.

We certainly support the increased use of non-polluting renewable energy. Wind will supply some of our renewable energy. However, before we rush to site wind turbines on mountain ridges, coastal sounds, or other sensitive areas, we need more study of the effects on wildlife.

Large Wind Turbines in NC mountains

The NC Senate Finance committee, a few hours ago, approved an amendment to a bill that would prevent the construction of large wind turbines in certain mountain counties. In addition, the bill would impose strict siting requirements on wind turbines in the coastal area. This is a victory for those who love to watch the birds soar along the ridge lines in the mountains, as well as those who love the views in the mountains.

In the coastal areas wind turbines have the capability of greatly disturbing the habitat of birds that fish in our sounds. While direct birds strikes is the most well known and discussed problem of wind turbines, (and, of course, very bad for the bird that was struck) another, less well known effect is on the bird habitat. Often birds in the hills and mountains soar on the updrafts. In coastal areas birds often feed in one area of the sounds and sleep in trees on land. They commute each morning and evening from one area to the other. Lines of wind turbines interrupt these commuting patterns and force the birds to move to other areas. In the mountains they prevent the birds from using the ridge lines for hunting small game.

I certainly hope that the full Senate and the House will approve the bill. Yes, we do need to find alternative forms of energy, but not at the expense of the birds and other wildlife.
