Yep, that's ALL they care about... nobody else.

When it comes to reliable baseload power, most of humanity has only three choices:

hydrocarbons—coal, oil, and gas

nuclear power

abandon modern civilization for a pre-industrial standard of living.

Don't forget geothermal and hydroelectric in the places where that is cheaply produced. Such as Iceland, which runs entirely on geothermal, and some areas along major waterways with significant elevation drop over a short distance and extremely high volumes of water at that high hydrostatic head.

And of course, a lot of renewable and fossil fuels failed spectacularly from February 14-20 2021.

I remember the 1993 Texas freeze vividly. 

I was in Houston in Nov. 1993, asleep in a hotel. The company I was visiting was right across the street. 

I woke up at 5:30AM to the sound of a gunshot. I immediately looked outside but didn't see any movement outside when all of a sudden, 3 minutes later, I heard another gunshot. So, I glued myself to the window looking outside when I actually witnessed the 3rd gunshot, but it wasn't a gun... it was the branch of a large oak tree on the lawns of the hotel that broke off and hit the ground. The weather had frozen the oak limbs and the frost/ice on the tree limbs were just too heavy and they broke off and hit the ground. 

15 minutes later, a really large explosion occurred and when I looked outside the window again, I noticed the transformer on top of one of the power poles was smoldering with smoke pouring out from the top and our hotel electricity went out.

15 minutes later, the hotel's auxiliary generator kicked in and we had power back on at the hotel.

I stayed in my room looking out the window at an onramp to a nearby freeway and watched in amazement as car after car after car attempted to climb that ramp to get on the freeway, but time and time again, they would start slipping partially up the ramp and slide... sometimes sideways back down the ramp. I think I saw more than 6 or 7... maybe even more cars attempt to climb the icy ramp, but nobody ever made it to the top. This was all before 6:30AM. 

Texas just ain't used to ice and snow!

But as it was a weekend, I didn't have much of anything to do until Monday morning when I was back at the customer's site again.

I'm probably one of the few people in the region who actually owns sets of tire chains for my vehicles. I had to order them on-line because of course they aren't stocked in any local / regional store.

I've had to use them maybe 3 times in the past 2 decades, but boy howdy, when I needed them, they were a total game changer, providing solid traction and control going down the road when the highway was deserted otherwise, or littered with wrecks that had slid off into the pastures.

These Wind Turbines Need Diesel Generators and Often Draw Power Instead of Generating It…

BY STEVE MACDONALD
23 MAY 2023

Aside from the hundreds of billions in misguided government support, wind power doesn’t have much going for it. It is not clean or green. It kills bats, birds, and now whales. And in Scotland, they’ve had to admit that without diesel generators to warm and back up the turbines, they might work at all.
 
Scottish Power admitted 71 of its windmills were hooked up to the fossil fuel supply after a fault developed on the grid.
 
The firm said it was forced to act in order to keep the turbines warm during very cold weather in December. But a whistleblower has told the Sunday Mail the incident is among a number of environmental and health and safety failings.
 
But wait! There’s More!
 
The worker said: “During December 60 turbines at Arecleoch and 11 at Glenn App were de-energised due to a cabling fault originating at Mark Hill wind farm. In order to get these turbines re-energised diesel generators were running for upwards of six hours a day.”
 
He also claimed there had been other technical issues and environmental problems discovered. They include:
 
Turbines left operating on half power for long periods due to faulty convertor modules.
 
Others in “test mode” where they take rather than contribute electricity to the grid.
 
Over 4000 litres of oil leaked from hydraulic units on turbines and sprayed over the countryside.
 
Concerns about safety standards and transparency.
 
The whistleblower said: “Turbines are regularly offline due to faults where they are taking energy from the grid rather than producing it, and also left operating on half power for long periods due to parts which haven’t been replaced.
 
“Dirty hydraulic oil is also regularly being sprayed out across the Scottish countryside due to cracks in mechanisms. Safety standards have not improved since a worker was killed in 2017 at Kilgallioch wind farm.”
 
Who among us dares to suggest that these concerns are more common than advertised everywhere wind frames are “planted” and have been for a very long time?
 
From the Institute for Energy Research (2015).
 
On October 4, the United Kingdom’s wind turbines produced almost zero electricity during the early morning hours. The UK has over 9,000 megawatts of metered wind capacity, but during that period on October 4, wind provided 66 megawatts—just 0.7 percent.[i] Many of these turbines are located either offshore or in the Scottish highlands, where wind is supposed to be the strongest. Because of the unreliability of these wind turbines (and solar farms), the UK government is subsidizing diesel generators over $670 million to provide back-up power.[ii] The country has 1,500 megawatts of diesel turbines registered for subsidies to provide that back-up power. The subsidies are so lucrative that solar farms are purchasing them to supply power when the sun is not shining.
 
As we drunkenly lurch Forward! (at gunpoint) toward the fantasy of a net-zero carbon 12th-century future, dare to ask what exactly the plan is to address these long-known systemic shortcomings. They will call you names and change the subject because, much like the path itself, they have no clue. No. Clue.
 
That’s what happens when you try to make energy science align with your political science. You get pushed off a cliff and told we’d learn to fly before we hit bottom while they watch from their fossil-fuel-powered comforts above.

When you need them you need them and can’t stop to buy them right away. It’s smart to have chains available.

Clearly there are some big design flaws in that system. When I worked on a wind turbine design about 40 years ago, we had it where it was "black start" capable.

That means, all you need to do to start producing electricity is spin the turbine. Once it reaches a certain speed, it can be synched to the power grid and switch it in.  If the grid is dark, it can regulate to 60 hz at the proper voltage and take a load.

Usually you need the chains on a day that obtaining them will take you a couple of weeks. But most people wouldn't be buying chains online in advance of winter in the South especially, where ice and snow is not a frequent thing, and many winters may pass between severe ice and snow events.

Major design flaws... not to mention the spewing of oil..

The green energy that wasn't as green as everybody expected it to be. (* CHUCKLE *)
