GM is pulling back on EVs

[Gregs24]

I already answered this. Only 1.7% of the worlds population is born that way. That’s something you should know if you’re going to debate it. And in those cases the predominant hormone dictates what sex you are. So if you have higher testosterone. Numbers then estrogen then you’re a male and if vice versa then you’re a female. See it all boils down to genetics. Open and read a book that might help.

On the contrary - you are confusing sex and gender

Here is something for YOU to read so that you better understand why you are wrong. What book did YOU use to distinguish the two as it seems to be incomplete at best?

Sex and gender: Meanings, definition, identity, and expression (medicalnewstoday.com)

Sex and gender - Gender Matters (coe.int)

Sex refers to “the different biological and physiological characteristics of males and females, such as reproductive organs, chromosomes, hormones, etc.”
Gender refers to "the socially constructed characteristics of women and men – such as norms, roles and relationships of and between groups of women and men. It varies from society to society and can be changed. The concept of gender includes five important elements: relational, hierarchical, historical, contextual and institutional. While most people are born either male or female, they are taught appropriate norms and behaviours – including how they should interact with others of the same or opposite sex within households, communities and work places. When individuals or groups do not “fit” established gender norms they often face stigma, discriminatory practices or social exclusion – all of which adversely affect health17.”

So what happens if you are born with both? or neither? What happens if you are a man that finds other men attractive but not women? Are all these people that don't exist in your mind - because I can assure you they do.

Gender and sex are NOT the same thing - funny that as they are two different words!

I’ll even go further. In the 60s,70, and 80, doctors would choose the sex of the child, and perform prepubescent surgeries. This would lead to life long issues with suicidal tendencies and depression to include clinical depression.

My bachelors is a bachelors of science in sociology yours?

I have had to write papers ad nauseam on these subjects. But this was long before crazies like you tried and take over the world.

Please post some links - would love to read your papers.

Plus those about pre-pubescent surgery you mention from the 60's to the 80's. Choosing the sex of the child (which we both know you cannot do) - are you confused with gender again? Who was choosing them and why?

I assume you mean by this you disagree with the two reputable links I posted together with the definitions? I'm not sure what 'crazies like me' is supposed to mean. Please be more specific.

I’d love to send you my papers, but you’d need a college education to be able to figure out the intricacies of the information. Maybe, if you learn to read at a higher level than a 5 yr old, we can have this conversation again.

Your math

Each gallon of gas is equivalent to 33.7 kilowatt hours of electricity.
How many gallons of gas are burned each day? How many are burned in an average size city per day?

This is an astronomical amount of power.
California uses 1,964,000 mega watts of power each day in gas and diesel

The figure you’re quoting here refers to the amount of electrical ENERGY contained within a gallon of gasoline, not the amount of ”work” being produced by that energy.

What it doesn’t tell you is that less than half of that energy is converted into motion in an ICE (Sound and heat should be the most obvious signs of efficiency losses). Meaning, that even if you take a brief moment to think about it, the conversion doesn’t work at all when trying to project future grid capacity.

If we were going to try and calculate future grid capacity using your method, it would need to look at lot more like this….

My sources tell me that an average EV (whatever that might be) consumes electricity at about 20kw/h per 100km. You need to add roughly 10% to that figure for transmission and charging losses. Call it 22kw/h per 100km, or 2/3rd’s of one gallon of fuel.
A gallon is 3.8 litres (near enough), meaning the equivalent of 2.5L/100km (~94MPG).

I don’t know of a single ICE car that produces those numbers and it certainly isn’t the average.

Given that even the most efficient ICE cars sit around 40MPG, the takeaway is that your proposed model overestimates the required grid capacity by at least 50%, probably a LOT more, I didn’t bother looking at the numbers too hard once I realised the error.

Experts typically suggest that the US will need between 20-50% extra capacity. (Best case/worst case scenarios).
European nations and the UK will require less as a result of shorter travel distances. I imagine Australia and Canada will be more like the US in that respect.

I calculated it out the first time using 1 gallon per day for each car in the State. The number I got from using that method fits your 20-50% range. It was about 45% increase.

It needed 7.5 square miles of solar panels and I forgot the number of wind mills, but significantly less. Still a lot. 7.5 square miles is a lot of land and this is only one state.

Hello; Some thoughts on the sex -gender discussion.
First any with whom Gregs still communicates with can ask him about this aspect. (I figure i am on ignore) At some point we each wind up having to see a medical professional, either a GP or a specialist. What does that doctor need to know about you in order to treat you properly? Among a few important things is if you are a biological male or female. Conditions and treatments can be specific for a biological male and very different for a biological female. Make no difference how you feel about it.
If we can decide our gender, then I guess we can decide our blood type. Makes as much sense.

Next is a language maneuver we all should be aware of by now. Get into a discussion where traditional and long understood meanings of words and terms are called into question, then the word salads start. Do not allow the spin and twisting of word meanings, such only encourages them. There will be no boundaries or reasonable stopping points. Example is the notion a biological male can be pregnant. That is absurd but will not be the end of such absurdities. Reminds me of two kids bragging about their dads. My dad can beat up your dad. My dad can beat up your dad with one hand. My dad can beat up your dad and mom at the same time with one hand and one eye. And on and on. There is no logical end to the word twisting because it is based on fantasy thinking.

What's funny about that though is that in terms of efficiency, cargo ships and tankers are WAY above everything else, especially when you factor in how much tonnage they haul for the fuel they use. The main issue is the persistent use of low quality fuels, like bunker fuel. Most western flagged ships are clean, but that's about it. Shipping is way less of an overall percentage of pollution in the grand scheme of things than you'd think.

Transportation of people and materials is always going to be an energy sink, no matter how you do it. There are certainly ways we can improve and be less wasteful though.

Hello; I get your point. Rail, barges and ships move huge amounts of tonnage for relatively small amounts of fuel per ton of cargo. Best I can recall is river barges are the most efficient.

I take a small exception to the notion of cargo transportation being somehow wasteful. In an idealized world we could recover 100% of the energy in fuels. Perhaps to be more accurate lose less energy to friction, incomplete combustion and other parasitic losses.
We are in a real world and even the revered "green and EV" solutions dreamed of will not be free of such losses. Even a BEV has a coolant system for the battery packs. Heat from the charging and discharging of the batteries has to be carried away in a radiator with antifreeze and hoses. That waste heat comes from the energy in the battery packs. Just one example.

Last point. It is the emissions from fossil fuels which are the main talking points in the global warming/ climate change fear mongering, is it not? The concern has not been the energy efficiency so much as emissions into the atmosphere. If fossil fuel could be burned at half the current efficiency but burned 100% clean the debate would be over, would it not?

I would say do 2 mega solar farms one in Arizona and one in Nevada. Plenty of sun 365 and plenty of unused government land that’s in desert area. Then supplement each state with wind just in case there’s a heavy summer or winter. If we did this we would be able to supply each state with more then enough energy moving forward. That would take care of all the lower 48. We can keep a power plant or two in Alaska because of the weather there and Hawaii could supply themselves with plenty of wind farms and solar also.

The American deserts are not "dead" land. There are many forms of life that live there. Solar farms in the amounts needed would destroy all of that life.

I really hope you were being sarcastic.

The only way solar works is if we cover buildings in the cells or put a massive solar farm on the moon and beam the energy back to earth.

I have an honours degree from a Russell Group university, so crack on and send the links!

Remember it is YOU that is ignoring the links I posted and don't seem to understand what gender means.

Which has got what exactly to do with gender?

This was all explained to him months ago, you are wasting your time

Example is the notion a biological male can be pregnant.

I’ve not once seen anyone claim that a biological male can become pregnant.
I have however seen people who identify as men becoming pregnant. I think it’s bizarre, but that doesn’t change the facts.

Here’s a thought experiment for you to ponder.

How do you know FOR SURE, whether someone is male or female? I’m talking about the person you see in the street. How would you go about determining their sex?
How could you possibly know if they’re DEFINITELY “lying“ to you?

Is it possible that in the past, people have managed To pass themselves off to you as whatever gender they’ve chosen, without you even realising it? What difference has that made to YOUR life?

More importantly, why are you so concerned about it?
I mean that, genuinely. Have you stopped to think about why it offends you so much?

It‘s kinda funny that the people who are all about “personal freedoms” get all bent out of shape when other people try and exercise their freedoms, especially when their choice has no impact on your life. Maybe you just mean YOUR personal freedom?
