I see the article mentioned the destruction of much land to acquire necessary minerals for electric vehicles, solar units, & wind turbines. Now wouldn’t it be a shame if we didn’t have those more or less useless things? If the demand for the minerals increases & it must, then we lose the land in large part, but the demand for the aforementioned minerals would still be there. It strikes me that there is a better way.
From a LinkedIn post:
Right now the average wind farm is about 150 turbines. 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.
Now you have to calculate every city across the nation, large and small, to find the grand total of yearly oil consumption from “clean” energy.
Where do you think all that oil is going to come from, the oil fairies? Not to mention the fact that the large equipment needed to build these wind farms run on petroleum. As well as the equipment required for installation, service, maintenance, and eventual removal. And just exactly how eco-friendly is wind energy anyway?
Each turbine requires a footprint of 1.5 acres, so a wind farm of 150 turbines needs 225 acres; In order to power a city the size of NYC you’d need 57,000 acres; and who knows the astronomical amount of land you would need to power the entire US. All of which would have to be clear-cut land because trees create a barrier & turbulence that interferes with the 20mph sustained wind velocity necessary for the turbine to work properly (also keep in mind that not all states are suitable for such sustained winds). Boy, cutting down all those trees is gonna piss off a lot of green-loving tree-huggers.
Let’s talk about disposal now.
The lifespan of a modern, top quality, highly efficient wind turbine is 20 years.
After that, then what? What happens to those gigantic fiber composite blades?
They cannot economically be reused, refurbished, reduced, repurposed, or recycled so guess what..? It’s off to special landfills they go.
And guess what else..? They’re already running out of these special landfill spaces for the blades that have already exceeded their usefulness. Seriously! Those blades are anywhere from 120 ft. to over 200 ft. long and there are 3 per turbine. And that’s with only 7% of the nation currently being supplied with wind energy. Just imagine if we had the other 93% of the nation on the wind grid... 20 years from now you’d have all those unusable blades with no place to put them... Then 20 years after that, and 20 years after that, and so on.
Golly gee, how green is that?
Oops, I almost forgot about the 500,000 birds that are killed each year from wind turbine blade collisions; most of which are endangered hawks, falcons, owls, geese, ducks, and eagles.
Apparently smaller birds are more agile and able to dart and dodge out of the way of the spinning blades, whereas the larger soaring birds aren’t so lucky.
I’m sure the wildlife conservationist folks are just ecstatic about that.
I’m so glad the wind energy people are looking out for the world.
