The Israeli company Nordic Wind is attempting to build more windfarms on unceded Sámi land. Our community has been joining forces with the Palestinian encampment in Tråante to protest and block these developments. No genocide on stolen land. #NoNordicWind

"Dear EarthTalk: What is wind repowering and why are environmentalists so bullish on it?

—H. King, Mesa, AZ

One of the most common forms of clean energy is wind power. People from around the world could recognize a wind farm from just one look. While wind power has been a staple in renewable energy since the idea’s inception, many of the original and old wind turbines have begun to show signs of aging. Wind repowering aims to fix this, by revamping old turbines with more efficient components, or putting in new, state-of-the-art turbines as a whole. These new components and units can reduce noise, more efficiently power a turbine, and a deliver a higher overall energy output.

Denmark, an early adopter of wind repowering, saw a 1.3 GW gain in capacity and a reduction of 109 wind turbines, enabling substantially increased wind energy production with fewer turbines. This promising data prompted a surge in wind repowering projects, and in 2019, 86 percent of wind energy projects there were classified as “repowered.”

These signs of success and scalability showed other countries the benefits of wind repowering. The U.S, with help from large energy corporations like General Electric, has more than 40 active wind repowering sites, with over 2,500 turbines having some type of renovation. This hefty wind repowering advancement is responsible for four gigawatts of energy, or the power for more than 30 million homes.

It’s no secret how fast wind repowering is growing, but upgrades can be made to many different types of renewable energy. Why do eco-advocates support wind repowering so strongly? Wind repowering has energy, financial, aesthetic and technological benefits. Not only does it make units more efficient, it also removes units that might be aesthetically unpleasing, or in less efficient spots than they could be. Wind repowering also increases the lifespan of turbines by as much as 20 years, and reduces the need for maintenance. Repowered turbines are also quieter, sleeker, and produce considerably more energy.

So, while there are many types of repowering efforts for other renewable energy sources, none are as comprehensive or successful as wind repowering. Not only is it a comprehensive option for revamping clean energy, but it does not require the entry costs that just building new wind farms requires.

The only barrier to wind repowering at the moment is legislation. Bills and policies cannot keep up with the demand for it. Readers should call local officials, or urge any nearby wind farms to look at wind repowering. Spreading awareness is the first and most important step."

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.

Wind, Coal, West-by-god-Virginia

Interesting to see an article about a place so close to where I live:

I think that, on a national level, we should do a better job of supporting people whose livelihoods are being eliminated. Yes, we need to support wind and solar and get rid of coal. We must and will do that. However, people and whole towns are suffering pretty badly in the transition.

"There’s something deeply comical about suggesting that seagulls are smart enough to wait for you to look away before stealing your french fries, but dumb enough to fly into wind turbine blades.

A two-year study on the interactions of several seabird species at an offshore wind farm found that not a single case of birdstrike was recorded over the study period or in the 10,000 videos taken.

Looking at herring gulls, gannets, kittiwakes, and great black-backed gulls, Swedish state wind company Vattenfall found that most of the birds maintained a 50 to 230-yard distance between themselves and the radius of the spinning turbines.

“This is the first time that any kind of bird species has been studied this closely and in detail at an offshore wind farm,” said study author Henrik Skov. “And these birds are really good at avoiding the turbines. Now we need studies on more varieties.”

The study was conducted on a wind farm consisting of 11 offshore turbines near Aberdeen, Scotland. It used radar surveys and mounted video cameras to gather data.

Why these seabirds avoided the turbines could be down to the individual species observed since other studies have shown seabirds tend to rank high in offshore wind turbine mortality, and of medium risk for land-based wind turbine mortality.

Skov also offered that it could be the turbines are, for one reason or another, outside of prominent flight corridors, and therefore aren’t where birds have historically flown either for migration and nesting purposes, or feeding.

The study is a big milestone in scientists’ attempts to learn how and where to build wind turbines so that they don’t interfere with birds’ flight patterns. If there is something in the data of this study or future observations that could reveal the secret as to why there was no mortality at the Aberdeen wind farm, it could mean that hundreds of thousands of birds could be saved in the future."

Good Climate news

Climate optimism doesn't ignore reality like so many believe. Instead it focuses on the good that can and is happening as we address the climate crisis while also being aware of the issues. Because without hope, movements fail.

Tórshavn, Faroe Islands, 2023.

While one of the windier places on earth, the Faroe Islands are still experimenting with wind power. There is an abundance of hydropower, exploited and potential, and the goal is to come close to 90 per cent clean energy in the next decade.
