Wind turbine blades fly off in NYC high winds

“Blades from a massive wind turbine crumpled to the ground Monday, smashing a car flat and damaging another piece of infrastructure, authorities said.” click here

Wind power creates global warming…

Lee Miller, David Keith. Climatic Impacts of Wind Power. Joule, 2018, Volume 2, Issue 12, P2618-2632.

We find that generating today’s US electricity demand (0.5 TW e) with wind power would warm Continental US surface temperatures by 0.24°C. Warming arises, in part, from turbines redistributing heat by mixing the boundary layer. Modeled diurnal and seasonal temperature differences are roughly consistent with recent observations of warming at wind farms, reflecting a coherent mechanistic understanding for how wind turbines alter climate. The warming effect is: small compared with projections of 21st century warming, approximately equivalent to the reduced warming achieved by decarbonizing global electricity generation, and large compared with the reduced warming achieved by decarbonizing US electricity with wind. For the same generation rate, the climatic impacts from solar photovoltaic systems are about ten times smaller than wind systems. Wind’s overall environmental impacts are surely less than fossil energy. Yet, as the energy system is decarbonized, decisions between wind and solar should be informed by estimates of their climate impacts.

Wind turbines are an unreliable electricity source

“The main operating constraint of wind poweris, of course, wind speed. At the low end of the scale, you need about a 6 or 7 miles-per-hour wind to get a turbine moving. This is called the “cut-in speed.” To generate maximum power, about a 30 mph wind is typically required. But, if the wind speed is too high, the wind turbine will shut down. This is called the “cut-out speed,” and it’s about 55 miles per hour for most modern wind turbines.” click here

Wind turbine installations destroy critical habitat

“And according top Rainer Hülsheger of the state association for natural landscape protection: “At least 12,000 square meters of forest needed to be cleared in order to build one wind turbine alone.” “ click here

Wind energy is an unsustainable energy technology (Money down the drain.)

“Last week the lobbying arm of the wind energy industry made an unsurprising, though somewhat embarrassing, announcement. It wants a longer lifeline with federal subsidies. So much for wind being the low-cost energy source of the future. ” click here

Wind energy is an unsustainable energy technology

“Cronies live and die by the government sword,” Bradley said. “Each and every wind project depends on large tax subsidies as well as preferential federal regulations to be built.” click here

Wind turbines create a huge solid waste disposal problem

“One wind farm in Glenrock and two from the Saratoga area have partnered with the Casper Regional Landfill to dispose of their old wind turbine blades.

More than 900 blades will be brought to the landfill beginning now until the end of next spring.” click here
