The World’s Largest Wind Turbine Has Been Switched On::It’s turbo time.
According to the corporation, just one of these turbines should be able to produce enough electricity to power 36,000 households of three people each for one year.
These types of statements always trip me up. Why one year? If it’s producing that amount of energy in that same year, shouldn’t it just be “…power 36,000 households of three people.”?
Because it does not run at the same capacity 24/7. Sometimes it produces energy for 0 households and sometimes for 50,000. Total production in one year corresponds to the yearly consumption of 36,000 households.
So they could just as accurately say “…power 36,000 households” And then fill in anything afterwards. “for 1 year”, “for 5 years”, “for the life of the turbine”. Or just leave it at 36,000 households. The “1 year” is so meaninglessly superfluous it annoys me. I mean, everyone knows they don’t produce power 24/365. That fact is always one of the disingenuous anti-renewable energy talking points.
In engineering, it pretty common to calculate things over a 1 year period in order to relate cost calculations to company finances. Most companies calculate their finances annually, so calculating for yearly average energy production makes any comparison easier than other arbitrary periods of time.
But it’s not superflouos? The number is apparently based on yearly average. Not on 5 year or over the total lifetime. And it does not produce only for 36,000 households but likely for many more. I don’t see why thin seems so meaningless to you or annoys you so much.
They’re leaving out an important part of the claim.
I can set up some piezoelectric things in my office chair such that when I sit my fat ass down it generates a small electrical charge. I can say that my ass can generate enough electricity to power a million homes for 10 years, assuming I don’t tell you how long it takes to generate that power, which would be on the order of decades, if not centuries, if not longer.
I’d wager someone saw the average energy output for the expected service lifetime of the turbine, then was like, “How much energy does one 3-person household use?” and started playing with Excel until they got a good mix of time and # of households for the press release.
Does make me wonder if they mean an average. Like if the lifespan of the turbine is 50 years or whatever, so instead of saying 720 homes for 50 years they say 36,000 for one year to make it sound more impressive?
Going by their estimate of 36.000 households and the Dutch average yearly household usage of 3.500KWh that would be 126.000 MWh per year. One turbine is rated for a continuous output of 16MW which assuming it runs continuously, would give you 16x24x365= 140.160 MWh in a year.
I would assume they actually mean 36.000 households yearly assuming average weather conditions.
Because using a yearly average is useful to account for fluctuations in power generation due to the change of the seasons. It might produce 50% of its power in 3 months if the fall usually is particularly windy in that part of the world.
One eVinci micro reactor is enough for 5,000 homes a year and doesn’t depend on weather.
So, instead of manufacturing each of these giant blades that might last 20 years, we should instead be manufacturing three microreactors that are much smaller and easier to transport.
just one of these turbines should be able to produce enough electricity to power 36,000 households of three people each for one year.
per year? per lifetime? per second?
I took it to mean that in 1 year it will produce the equivalent amount that 36k 3-person homes would use during that same year.
50,000 square meters (nearly 540,000 square feet)
That’s approximately 4 square Walmarts
Article is inaccurate:
The behemoth is 152 meters (500 feet) tall, and each single blade is 123 meters (403 feet)
This is impossible, the total height cannot be lower than twice the length of the blades.
I found a better article: https://electrek.co/2023/07/19/16-mw-offshore-wind-turbine/
has a rotor of 260 meters (853 feet)
So it must be more than 260 meters high. Maybe 152 meters is the height of the tower? Generally the height of a turbine is measured as the high point of the wing tips. Which is what for instance air traffic must observe.
It is the tower that is 499 feet tall. https://www.sciencealert.com/the-largest-and-most-powerful-wind-turbine-ever-built-is-now-operational
Yes I figured as much, and added it to my comment.
It’s an impressive turbine, but whether it succeeds commercially remains to be seen.
It beats the Vestas 15 MW turbine, which has been tested for 3 years, and goes into production next year.
PS. The Vestas turbine is 280 meters high.
Won’t somebody please think of the Albatross?!
