Is Wind Energy Bird Friendly?

A friend of mine, Burnie Gould, informed me that wind turbines could be dangerous to birds and disrupt migration patterns.  He made me stop and think.  And then I Googled.

Jessica Regan wrote, Offshore Wind in Coastal North Carolina: A Feasibility Study  for her Master of Environmental Management degree in the Nicholas School of the Environment and Earth Sciences of Duke University.  The objective of this study is to evaluate and analyze data related to the construction of an offshore wind facility located in coastal North Carolina in order to determine whether or not a renewable energy project of this scope and magnitude would be feasible. In order to determine how feasible such a development would be for coastal North Carolina, several different aspects of the project will be analyzed: Ecological impacts, including potential changes in coastal geology and climate patterns; regulations and legal issues; economic issues; and the public’s perception of wind energy. Based on these analyses, recommendations will be made as to whether a project of this scope would be a reasonable undertaking.

Jessica where are you?

According to American Bird Conservancy:

Pressure from environmental organizations to make wind energy bird friendly and therefore truly green is showing some initial signs of changing the attitude and behavior of wind developers and the federal government. A U.S. Fish and Wildlife Service advisory committee has now begun the task of writing recommendations to protect birds from habitat destruction and collision risks associated with wind farms, but much work remains to be done to convert an industry and their regulatory agencies that have long viewed wind power as environmentally benign. “

The push for a massive expansion of renewable sources of energy has tremendous potential for improving environmental conditions and moving us towards the goal of energy independence,” said Steve Holmer, American Bird Conservancy’s Director of Public Relations. “But we must make sure that in the rush for sustainable power we do not sacrifice sensitive habitats and bird migration corridors, or impact bird and bat populations through needless fatal collisions with spinning turbines.

Green energy is only going to be green if we take into account all the environmental factors.” The current energy plan for the United States calls for 350,000 megawatts of power generation capacity from wind energy by 2030, which is predicted to require building wind farms to cover a total of 19,000 square miles of countryside—approximately the combined areas of Massachusetts, Connecticut, and New Jersey.

The effects on birds and bird habitats could be significant, and require close attention and mitigation. To help with mitigation efforts, The Nature Conservancy has produced a map of the United States identifying sensitive areas to wind power development, and NRDC and National Audubon Society have joined with Google Earth to produce a map of 13 western states identifying areas where wind developments should be avoided.

American Bird Conservancy and Cornell Lab of Ornithology are working to further the development of computer models to predict risks to migrating birds from wind projects. The approach uses data gathered by weather radar stations across the country to predict both where concentrations of birds will occur during the migration seasons, and the weather conditions that could force birds to fly at lower elevations, increasing the probability of collisions with wind turbines. These models would allow wind projects to temporarily shut down, avoiding avian collisions. A similar project has been introduced by Iberdrola Renewables, which incorporates real-time radar developed by DeTect, Inc. for use at a wind project in coastal Texas. This system uses DeTect’s airport bird-strike avoidance radar to identify flocks of migrating birds and automatically shut down the wind project when the risk of collision is high. While these recent advances point towards a better regulated and more responsive wind industry, many projects that may still be very risky for birds are being fast-tracked.

For example, several projects in the Great Plains states of North and South Dakota, Nebraska, and Kansas are going ahead without provisions to protect endangered Whooping Cranes. Cranes are well known to be at risk from collisions with electricity transmission lines, and thousands of turbines now being erected along the cranes’ migration route could provide an additional, serious hazard at a time when the population is already at a critically low level.

Construction of a demonstration wind energy project in Pamlico Sound could begin as early as next year, according to state officials who met with Outer Banks residents to discuss offshore wind energy Friday.

Governor Beverly Perdue, Senate President Pro Tempore Marc Basnight, and Representative Tim Spear hosted the meeting at Cape Hatteras Secondary School.

“If water levels are rising as predicted and we take no action, we will have made a terrible mistake for the people who come after us,” Basnight said in opening remarks to a crowd of more than 250 people assembled in the school auditorium.

Perdue told the audience that the state could position itself as a leader in “green energy,” developing innovative ways that would help the environment and also create jobs.

“Make no mistake though, every governor in America is thinking about this. North Carolina has to do as much as we can do safely or we will fail,” she said.

The Pamlico Sound demonstration project would be located seven to 10 miles offshore between Avon and Buxton and would consist of as many as three turbines, explained Harvey Seim, a marine science professor at University of North Carolina-Chapel Hill.

Duke Energy and UNC-Chapel Hill are putting the final touches on a contract for the energy company to build the towers. Officials said they still need to determine what permits would be needed for the test site because the state has no regulatory framework for development of wind farms.

The project would provide researchers with more information on environmental impacts, operation and maintenance, and other issues, and could lead to full-blown farms in the sound or in the ocean.

A UNC-Chapel Hill feasibility study released in August found that large areas of Pamlico and Albemarle sounds and some parts of the ocean are incompatible with wind farms due to limited wind resources, ecological impacts on birds, fish and critical habitat, close proximity to cultural artifacts such as shipwrecks, or conflict with military operations, commercial fishing and recreational activities.

Seim said the wind resource over the ocean waters off North Carolina “is among the best along the eastern seaboard.”

Frisco resident Johnny Baum urged researchers to pay heed to the weather conditions that can strike the Cape Hatteras area.

“Hurricane resistance is very important here,” he said, during the public comment period of the meeting.

Seim said the UNC-Chapel Hill study found that an offshore wind farm might create 9,000 permanent jobs.

But Ted Vogel who developed the state’s largest wind turbine located in Camden County, cautioned that North Carolina doesn’t have enough workers trained in turbine technology and would end up importing workers.

“I’m worried about the visible pollution of these sites, ” said Stewart Couch, owner of Hatteras Realty. Couch urged the state to study the economic impact of wind farms on tourism and on property values.

Some members of the audience raised concerns about the cost of electricity supplied by wind farms.

“Offshore wind power will cost more, and the economy here is already hurting,” said Frisco resident Virginia Luizer. She also said any further studies should be put on hold until the state received assurance that environmental groups and federal agencies would not protest development of wind farms due to habitat protection concerns.

But William Howard of Ocracoke disagreed.

“The cost of investment is far less than the cost of inaction. We must change the way we think and account for all costs, including environmental degradation and war and protecting areas overseas,” Howard said.

Jim Kinghorn, general manager of Cape Hatteras Electric Cooperative, said wind farms might lower the cost of electricity on the island very slightly. He said they could help the cooperative come into compliance with a state law requiring utilities to buy 10 percent of their power from renewable energy sources by 2018.

Most speakers indicated that they supported the concept of developing renewable energy sources, but they still had many questions for state officials.

Rom Whitaker, a Hatteras charter-boat captain and avid hunter, said he wanted to know whether access to areas around turbines for fishermen, hunters and other traditional users would be restricted.

Pete Peterson, a UNC-CH scientist who worked on the feasibility study, said access for fishermen would be regulated by the state Marine Fisheries Commission. He said judging from experiences in other places, trawling, gill neeting, crab potting, and recreational fishing shouldn’t be impacted, but long hauling and dredging could be restricted in the area.

Allen Burrus, member of the Dare County Commissioners, urged the state to make wind energy development a transparent process with information easily available to the public.

Elfland, the demonstration project manager, said the meeting Friday was only the first step in actively engaging stakeholders.

Outer Banks Ocean Energy Corporation

Outer Banks Ocean Energy Corporation is the commercial interest in developing windfarms.   You can visit their website and view a presentation slide show online.  Don’t forget to view the supplemental slides.

OBOEC ultimate goal is to develop an Offshore Energy Preserve that will provide electrical power through a hybrid approach, involving wind turbines, wave power and Gulf Stream current turbines. We are engaged in discussions with North Carolina utility companies, and the feedback is clear – there is support within the state’s energy industry for this kind of progressive action in order to meet the future needs of North Carolina.

The call to action for wind energy in the U.S. is increasingly tangible. Our national wind energy industry installed 8.5 billion watts (or 8.5 gigawatts) of new generating capacity last year – a move that channeled $17 billion back into the nation’s economy. OBOE’s Offshore Wind Energy Project will yield tremendous benefits for North Carolina and its residents and businesses, by supplying plentiful and reliable electric power and by pumping millions of dollars into the state and local economies.

Basnight: Wind Farm 2

as reported in the Daily Advance

State Sen. Marc Basnight, D-Dare, says a giant wind turbine isn’t something he would like to see in his front yard.

But when it comes to slowing down the growth of greenhouse gases and reaping the potential benefits of wind power off the North Carolina coast, there are other issues besides great sight lines to consider, he said.

“Change is not quickly accepted by me and less quickly by people on this island,” Basnight said. “But how does it impact you or I — and most especially you — if the water level were to rise as quickly as we read by some people who make predictions in the scientific world, (and) all of the Outer Banks are under water?”

The “island” to which Basnight was referring was Hatteras Island, site of a symposium on the feasibility of Outer Banks wind turbines put on by researchers from the University of North Carolina at Chapel Hill and attended by state leaders, including Basnight and Gov. Bev Perdue.

About 500 people, most of them Outer Banks residents, jammed into the Cape Hatteras Secondary School in Buxton for the presentation.

“This is one of those few times in our lives we are privileged to live where we intersect environmental things that are very, very important — the right choices for the environment with the right choices for our economy and for homeland security,” Perdue told the crowd.

Harvey Seim, a marine sciences professor at UNC, said a study conducted on the Pamlico and Albemarle Sounds suggests the areas could be prime locations for wind turbines.

According to Seim, three wind turbines in a test area in eastern Pamlico Sound could be built in about a 3-mile area, seven to 10 miles offshore in 16 to 20 feet of water. Each turbine would be about 500 feet tall, cost from $10 million to $12 million, and power about 1,000 homes, he said.

If the initial tests prove positive, thousands of windmills could be constructed offshore, creating thousands of jobs in eastern North Carolina, Seim said.

Perdue said the state needs to be at the forefront of green technology, especially wind technology.

“It’s clear to me that (North Carolina’s) competition is no longer the southern states, no longer America, but the entire globe,” she said. “I believe that North Carolina has the capacity to position herself as a global leader in green energy. I believe that through that placement, we can grow a fabulous green economy that takes care of our environment and our people while it also creates thousands and thousands of jobs to the people of this state.”

Perdue said she has also authorized a scientific study to look at offshore drilling, among other things.

“I have authorized a study to look at offshore exploration of gas and oil — can it be done safely and can we focus on second and third generation fuels?” she said. “What is it we can do as a state to harness the resources God has given us?”

Timothy Petit, a representative from Duke Energy, said his company supports the construction of offshore wind turbines and that ignoring the problems of global warming will not make them go away or bring the U.S. closer to countries like China that are already investing huge resources in wind and other alternative energies.

“I’ve heard people say we can’t worry about climate change and global warming because we can do everything we want to do and the Chinese don’t play. Let me tell you — the Chinese are playing,” Petit said. “The Chinese have begun to understand their contributions to this issue and there is a massive amount of investment in China today in carbon capture and storage, in wind and solar power — they’re all over this issue.”

Some citizens voiced concerns that government entities often make promises that are not followed through on. They also expressed concerns about the impact huge turbines would have on the environment.

For his part, Basnight said that doing nothing about climate change is no longer an option. Future generations are counting on the current one to act, he said.

“If the water is rising as predicted, if we take no action, if we sit back in this county of Dare and Hyde, if we absolutely turn our back and we are wrong, we have made a terrible mistake on behalf of the people who follow us,” he said.
