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.

Learning the hard way 100% renewable energy is unsustainable

“An inconvenient truth is hanging over Georgetown, Texas: Its celebrated shift to renewable energy doesn’t look like a national model these days. Electric rates are up. Critics are blasting the costs. And the city north of Austin is trying to figure out how to mitigate the situation.” click here

Renewable energy raises prices, sparks riots in Chile

“Chile, which is hosting a major U.N. climate conference in December, earned praise from climate activists for recently imposing a carbon dioxide tax on conventional energy sources and switching the Santiago Metro system to renewable power. Now, the people of Chile are rising up and firing a shot across the bow of other nations considering similar energy taxes and expensive renewable energy programs.” 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

Free money subsidies for renewable energy are unsustainable, ineffective and must come to an end

“After billions of dollars of “gifts” to the renewables industry, and a doubling of the wholesale electricity price, wind and solar power are still so inefficient and uneconomic that investors can’t make a profit without getting more free money.” click here

Walmart to remove Tesla solar panels

“Tesla’s relationship with Walmart took a turn, as the latter is suing the former because they want Tesla to remove solar systems installed at 240 stores following several of them catching on fire.” click here
