. . . but creating the steel and aluminum inputs is still mostly "primary thermal power", that is, they don't use electricity in the first place.
Steel, and recycling, maybe, but aluminum is made from ore using electricity, which is why so many aluminum smelters are located near hydro-electric power.
This is a good thing if you actually believe that evolution makes species better.
If you actually believe that evolution makes species better, then you better explain what "better" means. I'm pretty sure survival of the fittest just means being able to survive the given environment, not being some subjective "better" species.
I've never known of a place where you could just go to any polling place and vote, except for early voting, and there are not many choices where you can go to early vote. There's 16 early voting sites in my county, with a population of more than 700,000.

I still don't know what the hell a pivot table is. Every explanation I've seen extols how great pivot tables are without defining what they are. It still just sounds like a bunch of cells, rows, & columns referring and manipulating data in other cells, rows, & columns, just like any other part of the spreadsheet.

The statistics show that the more affluent the society, the fewer children are born, and the poorer the people, the more they have lots of kids.
Ground source heat exchangers are great, and greatly expensive, so there's no way I could afford one at my house. (Maybe if I was building a new house, and was willing to spend an extra $20,000 or so).
Base on your username, I'm guessing you're not in the US, but there are national codes being enforced by the US government that require minimum efficiencies for A/C equipment, and the worst efficiencies allowed are as good or better than typical good efficiencies from 10 or 15 years ago.
Thermal storage using water is big and expensive and results in more energy usage, not less. It does offset the afternoon peak demand in exchange for more energy consumption at night, which saves money by increasing the use factor for those big, base-load power plants. Unfortunately, that is just the opposite of what you want if you're generating with photovoltaics.
If you compare apples to apples, inefficient systems are more like 1.5 times the energy consumption of efficient ones, but the efficient systems are nowhere near 15 times the cost. If you figure the expected service life of the equipment and the maintenance and replacement costs, sometimes the more efficient is even cheaper.
It is only when you compare apples to oranges, like comparing a ground-source coupled central water-cooled system to window A/C units that you get big differences in construction cost and energy consumption.
Legionaire's almost always stems from a problem with water, not air-tightness. Air-tightness can result in other problems, but that's why there's a "V" in HVAC.
No, touch screens are worse, because you can't really touch and feel virtual buttons like you can with real buttons, so you have to look when using a touchscreen.
Happened to a colleague of mine about 4 years ago. He was working on a long spreadsheet that was tracking design review comments and responses for a construction project, and someone accidentally deleted it, so he had to reproduce all his work.
The reason Windows is dominant even today is because when PCs first came out IBM dominated the business market. So when IBM came out with their PC, business buyers saw the other brands as toys and decided to buy the IBM version. Since IBM bundled MS-DOS, and especially when IBM clones started shipping with MS-DOS, Microsoft became the defacto standard for application writers. There are many reasons MS held on to their lead, a lot of which was business familiarity, and a lot of which was dirty dealing with their monopoly on the PC.
Developer data acquired over the past decade of real street testing strongly indicates self-driving cars would save lives.
From what I've seen, the opposite is the case. Except under very limited, well controlled circumstances, current self-driving cars are significantly worse than the average human driver, despite all the faults of human drivers. That's not to say self-driving cars won't get better than humans eventually, just that I'm guessing that Waymo is going to severely limit the conditions under which it will allow its' self-driving taxis to drive, for now at least.
. . . on older cars from the early 80s removing the catalytic converter . . . could give you a boost in fuel economy no where near twice as much but 3-5 MPG.
Adding 3-5 MPG would double the MPG of the car I owned in the '80s. (Well, not quite, but not that far off)
Fomr your linked story:

So I would think twice about claiming Obama-era regulation reducing the release of lead is the problem.
First, TFA is about cement, not concrete.
Second, common ingredients used in production of portland cement include limestone, shells, chalk, clay, etc. (though I'm guessing shells are not that common)
Third, the process of turning shells into portland cement includes using heat to disassociate and drive off water and carbon dioxide, so still not very green from an AGW point of view. (Though some carbon dioxide will be re-absorbed as the cement ages.)
I don't want it to be the other guy's fault that I'm in a crash, I want to not be in a crash.
Agreed.
However, regarding shoulders, in the city there are no shoulders, there are parked cars. (and double-parked cars) In the area I live, many of the highway shoulders are unpaved and too narrow for a bicycle to use safely - pulling off to the shoulder would likely end up with your car in a ditch. And in many places on the expressway that have decent sized shoulders, shoulders have workers, disabled vehicles, stupid people driving around traffic, and, around here, signs that say "shoulder driving allowed for buses".
Also, driving to where the cars are "now" is a patently stupid idea, especially if it's a rear-end crash. Really, if you can't tell where the cars are going, you can't tell where to steer; they might stay in front of you. You're much better off stopping, and if you can't, you're too close.

Well, to be fair, carbon monoxide is one of the incompletely combusted hydrocarbons.
