“Produce more energy than takes to build them” ..define energy.

Trying to figure out the point of your thread.

I guess he’s trying to show it takes a whole lot of energy and resources to produce something capable of producing a little bit of energy.

That requires too much brain power on a Saturday morning.

Don't forget that oil gets changed regularly. No diff than a chevy. You don't let 'er run ten years on the same set of oil.

Went past a blade disposal yard near big spring. As I understand it there is no recycling these things and the only thing they can do is bury them. These were either cut in half or thirds and were in a pretty big field. I guess I dislike windmills less as they don't render the agricultural land useless like a solar farm would.

Also, the waste of a failed turbine is great. Those blades aren't recyclable. Maybe we can ship to China to be "recycled" (dumped into ocean).

Drove by a farm earlier and was wondering what the base looked like.
Have seen a couple iron ore mines in Michigan. Also know what it takes to get concrete these days.
“the average wind turbine that came online in 2020 generates enough electricity in just 46 minutes to power an average U.S. home for one month.”
So they average 843,000 kWh per month.
Just haven’t never really looked into them much.

Supposedly they are working on that or have started using recyclable blades, but I haven't confirmed widespread adoption of such.

“Each wind turbine needs 80 gallons of oil as lubricant and we're not talking about vegetable oil, this is a PAO synthetic oil based on crude... 12,000 gallons of it. That oil needs to be replaced once a year.
It is estimated that a little over 3,800 turbines would be needed to power a city the size of New York... That's 304,000 gallons of refined oil for just one city.”

Stupid idea for a post and worse execution.

Always wondered who does all the Amazon and yelp reviews.

That sounds like a decent average but i've seen some way higher than that depending on the availability, load demand and gen size. I did a review on a re-power a year ago that had units making well over double that. WTX is windy AF.

I’m pro oil and gas.
However, for perspective, New York City can use up to 6.6 million gallons of heating oil daily during the winter.
287 barrels of oil (equivalent to slightly more crude carried by a single tanker truck) per year to lubricate wind turbines isn’t a massive amount relative to the amount of oil used to heat the city.
Just saying.

The green movement produces more emissions than oil and gas industry

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.

The picture of rebar for the wind turbine base. Where does the steel come from? China.
Concrete for the base? China. See pie chart.
And yes the other poster about energy. Valid point. By the way, the ratings in the table are maximum capability based on ideal wind velocity. Actual net output is around a third of that number because wind isn’t constant.
Green energy is a racket. A government boondoggle. Period.
Coal, nuclear, natural gas, and hydro. It’s not all of the above. It’s the most cost-effective and reliable. Period. End of discussion.

Not entirely true. GE has built its blades to be able to break them down and use them as admixtures in the concrete for the foundations, so it goes back into a site when it gets repowered (upsizing the turbines on pretty much the same footprint as technology improves)
Posted on 5/13/23 at 2:50 pm to RealDawg
That foundation is huge.
These are typical for onshore less than 400' to top of turbine. This was on a project back in 2017/2018 I was on in upstate NY. See the goofy little frick in the blue shirt back left? He sucked

Pardon the ignorant question, but what is the lifecycle of the blades, how much wear and tear do they suffer? I would have thought they’d last a long time.
I am sure I could look all this up but it’s for conversational purposes.
