I believe they're required to be replaced every 20 years.
EDIT: Turns out I was optimistic

An average blade repair can cost up to $30,000, and a new blade costs, on average, about $200,000 [6]. The wind turbines built and established at the beginning of century, becoming old now. While most rotor blades carry post-installation warranties for one to two years, and with the expected service life of 15–20 years, this leaves much of the blade's maintenance outside the warranty window [6]. Typically, wind turbine blades require repair after each 2–5 years [8], thus, creating the permanent factor of costs increase for wind energy industry.

10-12 years is typical but they can go a 20-25 if there wasn’t any severe impact damage. Some get replaced from damage but more often they get replaced because there’s a new design that’s more efficient or better.

20 years now with proper maintenance.
I am not opposed to them in the mix. Just don’t sell them aa something they aren’t.
Have a mountain top toilet turbine near me that is a peak plant. Certainly costs more to pump water up than is recovered BUT it is there when you need peak power.
RIP coal plants.

They can complement a power grid but they shouldn't be the foundation, that's just idiotic.

They constantly wipe out birds but keep saying it’s all for ‘Mother Gaia’

And they are a
MAJOR EYESORE
Especially when they put them in our oceans and US GULF, it adds a measure of complexity to MARITIME NAVIGATION & creates obstacles which add extra danger offshore. Changes offshore transportation lanes and just adds another layer of BS so the Big Bankers can embezzle more money thru alternative BS!
they are KILLING MIGRATORY Bird Populations.
I HATE WIND TURBINES!
Stick with O&G & Solar

Not sure if “power” means heat. Likely just used power usage and notheat oil consummation as well (but maybe)
Assume that conversion would also require them all to switch out heating units and trash those.

Was thinking the same, just pointing out that the amount of oil used for lubricant is a relatively small amount.

Not necessarily being cautionary. The same people that support these as “green” would pretend they aren’t built from mined ore and resins and require petroleum to operate.

I'm surprised elon hasn't tapped in this business yet

Tesla makes storage that’s a nice addition to wind farms and can really crank up their availability. The rest of the turbine supply chain is pretty saturated with GE being the 800lb gorilla in the room. No one really wants to compete with that.

I was skeptical until we drove from Los Angeles east to Palm Springs.
It was a valley with wind and thousands of wind turbines. Lots of different sizes and spacings. With wind turning maybe ten percent of them. And what of the rest, you ask?
A lot had fallen apart with pieces scattered on the ground with NO maintenance being done. Others in the groups that were turning simply weren't running. Lots were facing in lots of different directions.
It was interesting because with all the potential, most were neither capable of generating anything other than debris or seemed to have lost either their ability to turn to face the wind or their ability to spin had stopped.
Follow Google earth to see the farms today along I-10 and all the spaces where there used to be something

We should go back to asbestos turbines.

So 7,000 Barrels of oil? That’s not shite. I work on offshore oil production facilities that produce 7,000 Barrels of oil in two hours.

It’s still not shite when you consider how much this administration has sold of strategic oil reserves and how much they’re limiting new drilling?

I worked for a wind turbine manufacturer for 6 years, I’m no loon just wanted to advance my career.
The amount of “fossil fuel” energy that goes into the assembly is absurd. Stainless steel, copper, the transformers, the gearboxes, the main shafts, etc all get produced by your good old fashioned steel mills and copper mines using gas, diesel, or coal.
Then you have the fiberglass aspect of the blades which aren’t recyclable, never mind all the paints and harmful chemicals used to coat them.
I ultimately left because the politics were absurd. On supply chain calls you had groups of folks openly campaigning for Biden and trashing Trump. Idgaf who you support but at work stfu
They’re a loss for the first 10 years until they finally start to make a little money for the owners. The amount of oil we’d bring in to fill up the gearboxes was laughable

That might be true for old units but modern ones are 5 or less with a 25 year useful life. I’ve seen one wind farm go ROI positive in 6 months.

It's hydraulic fluid. The windmills turn themselves to face the wind.

What is the typical amount of time for a farm to go ROI positive?

4-5 years for land based modern tech with average availability and demand.
