246 |
"Wind turbines are a major threat to birds, bats, and other wildlife." |
Wind power is a relatively minor source of mortality for birds compared to climate change, which threatens two-thirds of all North American bird species with a heightened risk of extinction. |
248 |
"Wind turbines are error prone and a threat to human health and safety" |
Turbine collapse or breakage are extremely rare, utilising safety mechanisms to survive extreme weather conditions, and the mortality rate from wind energy pales in comparison to the risks associated with fossil fuels. |
250 |
"Wind turbines destroy nearby property values" |
While there might initially be a small decrease in property values, the effect all but disappears with time and distance from a wind project and the presence of a fossil fuel fired power plant has greater impact on property values. |
