I'll let you decide;
These so called "environmentally-friendly" wind turbines are all well and good, but surely statistically 50% of the time the wind is blowing the other way? This will make them spin in the opposite direction, sucking power from the grid instead.

The wind turbines rotate to face into the wind and produce the maximum power. Most also have pitch control, so they can adjust for speed as well.

And, in lots of areas there is one predominant wind direction. In my place, there is far more wind from the east than from the west.
But one thing I a curious about: If the wind is coming from the north, then N-NW, NW, W-NW, W... and so on, the wind direction goes the entire circle around, and the turbine follows, all the way around. You get the power from the generator down to the ground through quite heavy cables. Will the twist up, just like a rope of hemp? Or is there a mechanism in the wind mill saying "Enough is enough! I must turn of for a little while so I can rotate back to Mark Zero, to unwind the power cord"? Or do they have sliding contacts? The big mills can deliver quite a few megawatts; that puts some requirements to a sliding contact!
Or is the generator steady, the blades rotating around the vertical generator shaft? To me it doesn't look like that from most photos; it looks as if the generator is located behind the blades, with a direct horizontal shaft from the blades to the generator.
I am asking out of pure curiosity and lack of knowledge - windmills are certainly far out of my field of profession!

Maybe it uses "brushes"; like (some) electric motors.

I just googled "rotating electrical connectors" and apparently that's what a "slip ring" does.

This brought "rotating knives" to mind.

But can they really transfer 5-10 megawatt of effect (that's what recent windmills can deliver!) across a sliding connection? If you have 0.1% loss, that is still a 10 kW heater! I guess that would be totally unacceptable. So, how large are the losses?

And governors to limit the turn speed as winds get higher.

Regarding that deer lady: If it is a prank, it is a good one! But really: In quite a few places with lots of moose (for deer as well, but the moose is a bigger problem here), they have actually put up tall fences along the highway for a few hundred meters so the the moose cannot cross, and then a gate, pre-warned by "Moose crossing" signs, a few places even with flashing orange warning lights in season (they are not equally active all year around). In a few places, they have rather built bridges over the four- or six lane motorway for the moose - letting them cross six lanes of cars driving 100 km/h is too dangerous even with controlled crossing points, signs and flashing warning lights.
In Norway, approximately 1500 moose are hit by cars every year, half as many deer, and 4-5000 venison. The moose is by far the most dangerous one, due to their weight and their long legs: When you hit them, they will fall over your hood and come through the windshield.
You proabably cannot read this Norwegian newsstory, but look at the top picture in Moose crash[^]. You don't want to experience something of that sort in 100 km/h!

Same issue with kangaroos here in Aus - that's why trucks have crash barrier/'bull bar' designed to throw the poor kangaroo up over the windshield, you don't want it coming in and kicking you to death

I've seen similar setups of fences and crossings while traveling the foothills in Arizona.
And I've seen moose/elk crossing signs that were a little more graphic; where the moose is standing in a "charge" stance with his antlers lowered

Google Translate did a pretty good job of translating the story, although the picture pretty much tells the tale -- thankfully no one was in the passenger seat and the driver suffered only minor injuries.
I know from personal experience how much damage a much smaller deer can do. Last Nov my wife & I were driving on a major highway when a deer jumped the cement median and slammed into the front driver's quarter panel of our mini-van. I was in the left lane and had a vehicle on my right, no room to maneuver. I had enough time to say "Oh, no!" before the deer hit us. The deer and I got a moment to look into each other's eyes from a range of 2' as it hit the vehicle, then it was gone.
We were doing 75 mph/120 kph and the deer weighed probably 110-120 lbs (~180 kg). Killed both the deer and the van (destroyed the front quarter, wheel assembly, driver door, and passenger door; damaged the rear quarter panel). The wife & I were shaken up but unharmed. I prefer to not think about what a 440 to 1,500 lb moose would have done ...

Same thing happens with solar panels at night too!

Maybe not carrying solar panels on their backs, but there are a number of solar panels mounted on the rooftops. So there is some experience, both daytime and nighttime experience.

It gets even worse when you try to run a computer with the power from the turbines. When the voltages are reversed, everything works backwards. Input ports become output ports, additions suddently are substractions, all signals are inverted and the programs are executed backwards. Half of the logic on your main board is dedicated to preventing this from happening*
* I actually could use some of that logic right now, but for a totally different purpose. If you want to overclock a processor, you have to monitor the core and bus voltages, the clock frequency as well as the processor's temperature very carefully. Having hardware to do this and reducing the clock frequency when the processor gets too hot would be nice. As a bonus, you adjust these things in the BIOS menus, instead of soldering.
