Interesting electrification analysis article

How efficient are solar panels these days? I wondered if they could be directly used to charge an ev battery?

My only point of reference is the new prius prime solar panel, that would take 1600 days for a breakeven point
Solar panels are relatively low efficiency. I’m sure if they were energy dense we’d have them on every EV roof and there wouldn’t be many complaints about them.
 
I've read that the maximum theoretical efficiency of silicon solar panels is about 33%. The limitation has something to do with a level of physics beyond my comprehension.
 
The author (Levin) is incorrect about the US contribution to global CO2 being only 14%. Because it's cumulative it's actually 25%, twice that of China. Then work that out per-capita.
But it's not 1980 anymore so it's far too late anyway. We've all made our bed and must lie in it.
You do realize that every living plant on the planet is an automatic, free carbon sequestration, right? The more CO2 in the atmosphere, the more robust growth plants experience. Same thing with a measly 0.3*C increase in temps over the past 40 years.

Not once have I ever seen a plant in the arctic tundra outgrow a plant in an equatorial rainforest. Have you?
 
I won't be drawn into the ridiculous argument you've raised. I've simply stated that the author was incorrect with that one fact, easily verifiable from multiple sources.
The article you posted looks like typical kook fringe lunacy.

the United States has emitted more CO2 than any other country to date: at around 400 billion tonnes since 1751, it is responsible for 25% of historical emissions;

It looks like China has managed to produce more than half of the US produced since 1751 since 1950.
 
I could care less about electric vs ice. My problem is the overloards taking my freedom of choice away. Telling me what I can and can't purchase by pushing their regulations. That's my 2 cents.
I’ve posted it before but we’re about 50 years too late on that with the automobile. I personally think emissions regulations have done a lot to clean up the air and as they tighten it’s going to be hard to do certain things. This last jump might have been a bit much. The easiest way to keep ICE with tighter emissions is smaller more efficient cars.

Relatively cheap fuel has allowed us to ignore smaller cars. People seem to want the most they can get no matter what. If fuel got unnessarily expensive that would change things. I’m sure that would drive more EV adoption and smaller more efficient vehicles.

Weird. This article says a study by University of Illinois Chicago (pretty solid research place, even if I dislike the city’s politics) says 94% of ALL temperature-related deaths are from cold weather. Makes you wonder about the official narrative that the oceans are going boil, eh?

https://phys.org/news/2020-08-cold-weather-accounts-temperature-related-deaths.html

UIC study report said:

Results​

The crude annual total hospital utilization incidence rate for heat injuries was 23.6 per 100,000 residents compared to 23.2 per 100,000 residents for cold injuries, however, the crude annual inpatient admission incidence rate was more than four-fold higher for cold injuries compared to heat injuries (10.2 vs 2.4 per 100,000). Although hypothermia made up 27.0% of all temperature related injuries, it comprised 94.0% of all deaths.

Emphasis mine. Cold was responsible for 19 out of every 20 “climate-related” deaths in Illinois over a decade, and I doubt anyone would consider Illinois a particularly frigid place to live.

Tighter vehicle emissions regulations have done nothing to improve air quality for about 99% of the land area of the country.
 
This was originally found on Americanthinker.com, by William Levin, titled, “The Electric Car Con Explained”. I would link to it, but had to remove the hyperlinks, a few lines and one paragraph that would run afoul of board rules. You can always use the data above to find the full article. Interesting what the data really appears to say about EVs/Electrification and the political boogeyman that’s being pushed:



Guys like @OVERKILL @MVAR and others in the power industry… does this jibe with known data you guys have seen?
Unfortunately AmericanThinker.com is conservative biased . So article merit comes into question and “data” harder to swallow when tweaked, twisted or torqued a bit to support agenda.

So you’re stereotyping authors unknown to you simply by where the article was published, and discounting the mountains of government and private data that was used to support the article’s thesis?

The way I read that article, the only “agenda” was, “the data shows there’s no support for forced mandate conversion to EV; let the consumer decide what best fits their budget and personal goals, since the ICE/EV argument as far as climate impact goes, is entirely moot due to the insignificance of scope, and clearly not justified when considering the expansive financial expenditure of taxpayer monies.”

There’s zero political twisting when saying “everyone suffers under these provably unjustifiable policies.”

So you’re agreeing that ICE cars have less than 1% impact overall for emissions and air quality, and further regulations or removal of ICEs will not change the results? Cool, we agree. Leave ICEs alone!

Not stereotyping, the article list published by author leans in certain manner so you pick your facts to support your “thesis” so you can get paid and your thoughts out there.

It sure has for dense populations. I guess though that we should rip our cats off in flyover country.
Yeah there's people who will take them off for free at night. No one replaces them, just have the exhaust shop weld in a pipe, putting in a nother converter is an additional few hundred dollars and it will just get removed again.

Doesn't make it the right thing to do. I was amazed by that when I tuned my car that everyone made sure to tell me to get a tune that allowed a cheap upgrade for the catless tune. I'm not pulling the cat, I don't want to smell the results of an uncatted car. It's horrible and illegal for a reason. The fact is in all of these areas that do not have emissions testing is that it will never keep the car off the road.

The top things that effect pollution where I am are farming and weather and a few times a year I smell the oil wells from around Lubbock, tx.
Only thing the ice needs to compete and beat electric cars well into the 21st century is it's own optional tiny hybrid battery pack.

That's not even close to accurate. Realistically the average person just needs to stop buying trucks when they don't tow and that would be more of a shift than switching to EVs. The problem isn't that we need EVs, but that we need the average person just to not be gluttonous pigs and that would save the ICE vehicle within emission standards. We could even have fast ICE vehicles that are still efficient in this case. There's still a decent amount under our noses, but they're dying off as every person thinks they need an SUV or truck to survive in this world and it's just not the case. I would love it if everyone actually saw the merit in hot hatches. We'd all have fun, spend less in fuel, have nearly the same interior space, and take about 2k lbs per vehicle off the road.
