INTRODUCTION AND BACKGROUND Introduction The Great Plains offer incredible potential for wind energy and North Dakota is no exception (Figure 1). It is estimated that North Dakota has a potential capacity for wind generation anywhere from 394,519 MW up to 742,276 MW (depending on hub height), with only 2,996 MW currently installed (Office of Energy Efficiency and Renewable Energy; AWEA Market Report; 2017; AWEA March 14, 2018). Figure 1. U.S. Wind Power Resource at 80 Meter Hub Height (NREL). With an increased focus on reducing greenhouse gas emissions, energy resources considered to be less harmful to the environment are becoming more important. However, without appropriate planning, solutions intended to decrease greenhouse gas emissions can turn into new challenges. Wind energy has a larger spatial footprint than other energy resources and, as the demand for energy continues to grow, that footprint could result in an increased loss of habitat, which may lead to additional listings under the Endangered Species Act, ecosystem 2 collapse, and a loss in biodiversity. This poses a great risk to North Dakota, which harbors large, contiguous stands of native prairie, which is one of the most endangered ecosystems globally. Maintaining a healthy balance between developing our energy resources and conserving wildlife and habitat is key if we hope to preserve our current rich natural heritage and appreciation of outdoor values while still promoting responsible development of North Dakota’s natural resources. North Dakota is a wildlife rich state that has many resident and migratory species which depend upon the grasslands, wetlands, and the sparse woodlands the state provides. Over the last century, urban expansion, conversion of native habitats to cropland, and energy development have greatly altered the landscape. As a result, many species have suffered as their habitats have been fragmented, degraded, or even lost. In 2007, there were 7 threatened or endangered species in North Dakota (including one plant). In 2018, that number has increased to 12, with 11 more currently under review for listing.. As managing for listed species is far more restrictive, difficult, and expensive than preventing listings, it is vital that we maintain the key habitat resources needed to sustain healthy populations on the landscape. In 2015, the North Dakota Game and Fish Department’s State Wildlife Action Plan (SWAP) was approved. The SWAP was reviewed by a group of officials from the U.S. Fish and Wildlife Service and state wildlife agencies, and a public review process was conducted with input from a wide array of conservation groups, academics, NGO’s, farm groups, and members of the public. The SWAP serves as North Dakota’s comprehensive wildlife conservation strategy for the next 10 years and is the principle document for safeguarding fish and wildlife species in North Dakota. The SWAP identified 115 Species of Conservation Priority that represent rare, declining, or unique species in North Dakota. The ultimate goal of the

  • Wind Powering America FY07 Activities Summary
    Wind Powering America FY07 Activities Summary Dear Wind Powering America Colleague, We are pleased to present the Wind Powering America FY07 Activities Summary, which reflects the accomplishments of our state Wind Working Groups, our programs at the National Renewable Energy Laboratory, and our partner organizations. The national WPA team remains a leading force for moving wind energy forward in the United States. At the beginning of 2007, there were more than 11,500 megawatts (MW) of wind power installed across the United States, with an additional 4,000 MW projected in both 2007 and 2008. The American Wind Energy Association (AWEA) estimates that the U.S. installed capacity will exceed 16,000 MW by the end of 2007. When our partnership was launched in 2000, there were 2,500 MW of installed wind capacity in the United States. At that time, only four states had more than 100 MW of installed wind capacity. Seventeen states now have more than 100 MW installed. We anticipate five to six additional states will join the 100-MW club early in 2008, and by the end of the decade, more than 30 states will have passed the 100-MW milestone. WPA celebrates the 100-MW milestones because the first 100 megawatts are always the most difficult and lead to significant experience, recognition of the wind energy’s benefits, and expansion of the vision of a more economically and environmentally secure and sustainable future. WPA continues to work with its national, regional, and state partners to communicate the opportunities and benefits of wind energy to a diverse set of stakeholders.

  • Usa Wind Energy Resources
    USA WIND ENERGY RESOURCES © M. Ragheb 2/7/2021 “An acre of windy prairie could produce between $4,000 and $10,000 worth of electricity per year.” Dennis Hayes INTRODUCTION Wind power accounted for 6 percent of the USA’s total electricity generation capacity, compared with 19 percent for Nuclear Power generation. A record 13.2 GWs of rated wind capacity were installed in 2012 including 5.5 GWs in December 2012, the most ever for a single month. The total rated wind capacity stands at about 60 GWs. Utilities are buying wind power because they want to, not because they have to, to benefit from the Production Tax Credit PTC incentive. The credit has been extended for a year to cover wind farms that start construction in 2013. Previously it only covered projects that started working by the expiration date. Asset financing for USA wind farms was $4.3 billion in the second-half compared with $9.6 billion in the first six months of 2012. Component makers are the General Electric Company (GE), Siemens AG, Vestas AS, Gamesa Corp Tecnologica SA and Clipper Windpower Ltd., which is owned by Platinum Equity LLC. Equipment prices for wind have dropped by more than 21 percent since 2010, and the performance of turbines has risen. This has resulted in a 21 percent decrease in the overall cost of electricity from wind for a typical USA project since 2010. From 2006 to 2012 USA domestic manufacturing facilities for wind turbine components has grown 12 times to more than 400 facilities in 43 states.

Wind power can dramatically reduce the environmental impacts associated with power generated from fossil fuels (coal, oil and natural gas). Electricity production is one of the largest sources of carbon dioxide (CO2) emissions in the United States. Thus, adoption of wind power generating technologies has become a major way for the United States to diversify its energy portfolio and reach its expressed goal of 80% reduction in green house gas (GHG) emissions by the year 2050. The benefits of wind power plants include no fuel risk, no carbon dioxide emissions or air pollution, no hazardous waste production, and no need for mining, drilling or transportation of fuel (American Wind Energy Association, 2009a).

  • Wind Energy Permitting
    14. Permitting New York State recently adopted the Power New York Act, which includes Article X, legislation establishing a state-level process for permitting electrical generation facilities of 25 MW and larger capacity. Under Article X, utility scale wind farms are now sited and permitted by a state siting commission, rather than by local municipalities. However, the state siting commission may defer to local ordinances, or it may overrule local requirements it considers to place an unreasonable burden on the applicant; so it remains incumbent upon municipalities to establish zoning and/or planning ordinances that balance wind energy’s clean electricity generation potential with the public health, safety, welfare concerns that may be involved. Furthermore, residential scale wind turbines, and wind farms of less than 25 MW, will still fall under local municipal control. This section is intended to provide local officials with the information and tools needed to create meaningful and reasonable zoning and planning documents for wind energy facilities. 14.1. Local Ordinance Options and Examples Effective wind ordinance standards should address several objectives, including: ensuring public safety, expressing local preferences, identifying and minimizing on- and off-site impacts, promoting good land use practice, informing and involving the public and providing legal defensibility. Clear and reasonable standards provide fairness for towns, wind developers and the public, and make it less likely that local standards will be overruled in the siting and permitting process. For small wind farms and residential scale turbines, clear standards can help make for a smooth and expeditious review process. Local Review Options A town does not have to employ zoning to develop and adopt a wind energy ordinance, although it is preferable as it better assures that the town will get the type of development it wants.
