Wind Turbines and Radar Siting and Barrier Mitigation Wind plant installations offer lower electricity rates, reduce greenhouse emissions and improve air quality. However, like any form of energy installation, they impact surrounding areas. As the number of large wind plants in the the U.S. grows, the potential for wind turbines to interfere with radar missions … Continue reading Siting and Barrier Mitigation – Sandia Energy
Preview of coming attraction - we are having accurate topographical maps and 3-D views created to show the turbine viewshed. This preliminary example is based on just 2 turbines. They would be visible from any area shown in red. 47 more to follow. Not only during the day, but aviation lights will also be installed … Continue reading Preliminary topographical turbine viewshed.
Various Project Maps.
Wind Turbine Visibility and Visual Impact Threshold Distances Robert Sullivan | Visual Resource Analysis, Argonne National Laboratory' Field observation of wind facilities in western landscapes revealed that the facilities were visible at distances of 36 mi (58 km) in both daytime and nighttime views, and were found a major focus of visual attention at distances of … Continue reading Wind Turbine Visibility and Visual Impact Threshold Distances
Swept Area and Rated Power The power output of a wind turbine is directly related to the area swept by the blades. The larger the diameter of its blades, the more power it is capable of extracting from the wind. Rotor Diameter – This number is listed on most wind turbine spec sheets. It is simply … Continue reading Calculate the Sweep Area of Turbine Blades.
This Letter from Weyerhaeuser was made available by the Planning Commission at its Public Hearing on September 27. The company's request has implications for the proposed project, including the number of turbines, their size and setback requirements. The devil is in the details, which aren't revealed. For example, what does "more energetic turbines" The Planning Commission … Continue reading Letter from Weyerhaeuser made available by the Planning Commission.
This is NOT about ONE project (Summit Lake). If they change the zoning to allow 500+ ft wind turbines in the forestry district, they will be allowed to be constructed with a special use permit in ANY of the area shaded dark green on this map (they already are allowed in the lightest green)! History … Continue reading Extent of Forest District Land in L’Anse Township.
U.S. Geological Survey, Forest and Rangeland Ecosystem Science Center Overview As with many land uses, trade-offs exist between costs and benefits. New wind developments are occurring rapidly in parts of the United States, often leaving little time for evaluation of potential site-specific effects. These developments are known to affect wildlife, directly from fatality due to collision … Continue reading U.S. Geological Survey, Forest and Rangeland Ecosystem Science Center
