Turbine Failures and Plunging Stock Add to Growing Doubt Over Wind Industry

[Epoch Times] An increase in the failure of wind turbine components and the subsequent financial fallout is creating uncertainty about the true sustainability of an industry campaigning for green energy.

Siemens Energy announced on June 22 that it would be withdrawing its profit assumptions and initiating a technical review of Siemens Gamesa’s onshore wind farm, which could cost over 1 billion euros. "This is a disappointing, bitter setback," Siemens Gamesa CEO Jochen Eickholt said in a June conference call. "The quality problems go well beyond what had been known hitherto, in particular in the onshore area."

The mechanical problems could affect 15 to 30 percent of the company’s wind turbine farms and take several years to repair. The day after the announcement, Siemens Energy’s shares dropped over 37 percent.
A long list of issues at the link. This is only the first:
The company began an investigation into a damaged turbine at the Santo Agostinho wind farm that French energy company Engie SA is building in the northeast of Brazil, Bloomberg reported.

The installation—which is part of Siemens Gamesa’s new 5.X model of onshore wind farms with blades as long as 262 feet—has faced numerous quality control issues and has been shut down for the investigation.
80 meter, or 262-foot blades. I don't know the RPM, but somebody could calculate the speed of the blade tips. I hope the vultures can.

#1 It's not 'growing doubt' to some of us.

#2 My doubt went up in a cloud of feathers.

#3 Aw, too bad, Siemens. That's just too g-d damn bad.

#4 Let's See ....

EV's not a solution. --> Billions wasted in natural resources. Require 2.5x the nations current MegaWatt capacity. Plus Environment issues caused and massive HAZMAT disposal issues.

Solar Panels which die after just 5 to 7 years --> ZERO R.O.I. and the massive waste of natural resources. Plus Environment issues caused and HAZMAT issues in disposal. Plus Biden is talking Blocking Sun Light???

Wind Turbines not a solutions --> $$Billions wasted and the massive waste of natural resources

Hydro-Electric can't be used as it hurts/kills fish. So Breech the power generating dams, for the fish that haven't swam there in 75 to 100 years. But some how the fish still have continued to increase in numbers and live.

Nukes takes 10 years from start to finish. Need water to cool them, but we breached the dams and reservoirs.

Coal - which is in limited supply. Causes Environment issues and can only be safely used by Communist China ☺.

So what do we have left to screw with, and screw up?

Anti-Matter? Lets take out a city block for and accident.
Hydrogen power cars and houses using sea water? Well if the Ice caps are melting it would save a bunch of Island and coastal areas. ☺

Soylent Green based fuels? The Ga. Guide Stone did recomend trimming the world Population to 500 Million. 7 Billion bodies properly recycled could generate needed power.

BTW: what happen the GBI/FBI/ATF investigation regarding the Ga. Guide Stone Bombing.

#5 Every seen what a windmill looks like after a 100 mph microburst gust? Or a solar cell field after a major hailstorm? Rubble. The large footprints of these installation make them prime targets for 'weather events' ...and let's not mention the 'hurricane' word out loud.

#6 But but but... if only we had more wind and solar - enough wind and solar - we wouldn't have any adverse 'weather events' to damage our wind and solar.

Doncha get it?

#7 the speed of the wing tip can reach 90 meters per second (200 mph) in the model used by Siemens for offshore wind

I'm pretty sure they have an internal braking system that doesn't allow a faster motion

They also tested a 100 meter blade for offshore use but I don't think it has been installed yet

#8 What if we installed solar panels on the turbine blades? Would this roast the eagles on contact and save cooking time?

#9 Liquid Flouride Thorium Reactor - if we’re looking for an actual solution this is it. The thorium doesn’t need to be refined, it doesn’t require a lot of water, it can’t melt down and it has no weapons applications. Thorium is also everywhere in the earth’s crust.
