Wind turbine bird mortality is a by-product of large scale wind farms, which are increasingly promoted as an alternative to fossil fuel derived energy production. To adequately assess the extent of impact to avian populations, deeper factors than gross mortality by turbine action must be assessed. In particular, one must examine: (a) impacts to threatened bird species, (b) total impacts due to avian habitat loss as well as direct mechanical kill, (c) ecological impacts due to apex predator bird loss and (d) future siting decisions for windfarms, since much of the prior bird mortality is due to poor siting decisions.
Bird mortality from wind turbines is a significant adverse ecological impact, and threatens to expand in scope dramatically with the rush to develop new energy sources. This impact is measured as high due to the loss of threatened species and due to... More »
Wind Energy and Wind TurbinesLast Updated on 2010-07-12 00:00:00
Since 1999 the United States’ installed capacity of wind-produced electricity has grown from 2,000 mW to 28,635 mW, which is enough energy to power the equivalent of more than 6.5 million homes.
A functioning turbine can provide electricity directly to a building or other application as a “stand-alone,” or “off-grid” system, or it can be connected to the transmission grid. Hybrid systems can combine wind, solar, and, for example, a diesel or biogas electric generator to provide holistic energy security for off-grid systems.
A small wind turbine is one that generates 100 kilowatts (“kWs”) or less, and is generally used to produce clean, emissions-free power for individual homes, farms and businesses. As compared to large commercial turbines that may be 300 feet tall and are capable of producing several megawatts... More »
