OHMYGOD IT’S ATTACKING THE STATUE OF LIBERTY SOMEBODY DO SOMETHING

I know just the man for the job.

This is a good joke. This is such a solid, quality joke.

@explainingthejoke ?

The initial image is a size comparison between the statue of liberty and a wind turbine. The wind turbine is over ninety feet (about 28 meters) taller.

A commenter pretended to misinterpret the image as one of a wind turbine attacking the statue of liberty. The next commenter answered with an image of Don Quixote, a literary character who once thought a windmill was a monster and announced his plans to fight it. They are joking that if a wind turbine attacked the statue of liberty, Don Quixote would be willing to fight the wind turbine.

Incidentally, that scene led to the English idiom “tilting at windmills,” meaning a person who has not only disproportionate reactions of anger, but disproportionate reactions of anger to nonexistent challenges.

So all those people who are fighting to preserve coal jobs and the fossil fuel economy are….

actually…

tilting at windmills.

Wind is one of the cleanest energy sources available, and the US is sitting next to a gold mine. A new study has found that wind speeds over the oceans could allow offshore turbines to generate far more energy than a land-based wind farm – with the North Atlantic, in particular, theoretically able to provide enough energy for all of human civilization.

In tapping into wind as an energy source, the US has for decades lagged behind Europe and UK, which are home to the largest offshore wind farms in the world, including the London Array and the Netherlands’ Gemini wind farm. But the US is catching up: the country’s first facility opened up off the coast of Rhode Island last year, and if the Trident Winds project goes ahead, it could snatch up the title of world’s largest wind farm

Bladeless wind turbines generate electricity by shaking, not spinning

Scientists hope to hugely reduce the cost of wind energy by removing the blades from wind farms, instead taking advantage of a special phenomenon to cause the turbines to violently shake.

Vortex, a startup from Spain, has developed the tall sticks known as Bladeless — white poles jutting out of the ground, that are built so that they can oscillate. They do so as a result of the way that the wind is whipped up around them, using a phenomenon that architects avoid happening to buildings and encouraging it so that the sticks shake.

They do so using vortices, which is where the company gets its name from. The bladeless turbines use special magnets to ensure that the turbines are optimised to shake the most they can, whatever speed the wind is travelling at.

As the sticks vibrate, that movement is converted into electricity by an alternator.

World’s first floating windfarm to take shape off coast of Scotland: Turbines for £200m Hywind project will be towed from Norway across North Sea and moored to seabed off north-east Scotland.

You guessed it… Solar USB Chargers from Amazon!

Wind turbines that float and are stabilized with cables to the seafloor, rather than sitting directly on the seafloor themselves. Possibly a big step forward for offshore wind, since it will let wind farms move further offshore into deeper waters.

Wind power potential in the United States

@solarpunk-aesthetic what do you think of wind?

Wind is, in my opinion, the most easily accessible form of renewable energy after sunlight. Wind turbines need more maintenance than solar panels, but it’s an excellent source of energy for regions in the far north or places with prevailing coastal winds.

In fact, it’s been estimated that just 2% of Earth’s wind energy could easily meet all the world’s current energy needs. There’s a lot of work going into better ways to harvest wind power, which is definitely worth keeping an eye on!

While looking for this map I stumbled upon a whole series of great maps regarding wind potential in the US.

The higher you go, the more expensive the equipment, but the better winds you can harvest. Here’s potential wind capacity at 140 meter hub height.

This is map to get people excited – a 140 meter hub height turbine is freaking massive – and as far as I know have only been used offshore in Denmark: 720 ft tall monster Danish wind turbine creates insane amounts of renewable energy.

The top 3 wind energy producers in the world are China, Europe (incl Denmark), and the US.

Here’s the wind speeds at 30m – which is a common hub height for residential wind power.

and for comparison, here’s wind speeds at 80m, which is the height utility companies prefer:

It’s interesting to see so much wind in Texas set up, but you can see by comparing the maps just how much wind power is yet to be harvested in the northern great plains.

Wind does have environmental consequences. It kills untold numbers of birds and bats. There are no perfect ways of generating energy however, they all have downsides. Hydro destroys ecosystems and photovoltaic solar relies on mining. They’re all far better than what we have been using, like coal.

Even our very best and most modern power plants are only 50% efficient, so for every lump of coal we burn, only half of it makes it to homes and businesses in the form of electricity. Wind and solar aren’t used to make steam, so their losses are only in the transmission lines, and if they’re hooked up directly and immediately to a home or business, then there’s no losses to speak of.

Scientists invented fabric that makes

To create the fabric, researchers at
Georgia Tech wove together solar

used in “tents, curtains, or wearable
garments,” meaning we’d virtually
never be without power. Source

Y’all are fucking idiots. Clean energy will NEVER be enough to replace the energy we have now. We’d have to tear down DOZENS of forests just to fit enough windmills and solar panels to get even a QUARTER (probably less, tbh) of the energy we can produce now.

Yeah, sure, when they’ve already calculated that a few square miles of panels in the empty ass Arizona desert could power the whole nation. But ok, fracking and the diminishing petroleum supply is worlds better.

Nevermind that windmills are often most efficient off the coast. There they take up no land, impact no trees, don’t pollute the water, and are conveniently located where winds are often strongest anyway.

And solar panels can literally be built into roofs of buildings and in empty areas like deserts. The sun strikes the Earth with the same amount of energy in an hour that our civilization uses in a year.

But yeah, it would be impossible for us to ever have enough energy from clean sources.

Durr hurr technology is bad and I would rather light shit on fire than have clean energy

I can also testify to the Arizona desert being empty ass. And the California desert. And the Nevada desert. 

also…no forests were cleared to make space for Denmark’s windmills and yet they regularly produce so much power that it covers almost all of the country’s power needs. Oh, and then there’s the times when the windmills generate 140% of Denmark’s power needs. https://www.theguardian.com/environment/2015/jul/10/denmark-wind-windfarm-power-exceed-electricity-demand

Friendly reminder that oil pipelines are a scam.

The fact that anyone can believe a limited amount of dinosaur oil is more plentiful and efficient than moving air or fucking sunlight is proof that entire populations can be completely brainwashed.
