Update on the Ford EF-150

Ford’s Electric F-150 Lightning Could Far Exceed 300-Mile Range

If you were hoping for a little more than 300-miles per charge from Ford’s new electric F-150 Lightning, we could have good news. According to reports, the F-150 Lightning may offer up to 450-miles on a single charge and only hit the estimated EPA 300-mile range while carrying 1,000 pounds of payload.


Plus an interesting tidbit which relates a little to earlier discussions about range and load.

... the truck has a weight system in the back that will adjust range estimates based on weight.
 
As a Vermonter I would also add that Tippit's comments on the sources of electric power are regional, as well as being subject to change. Fortunately we are not all governed by the coal and oil lobbies.
 
Just to add a couple cents here, there’s also economies of scale. Even if one assumes the same fuel in a power plant and a vehicle, the centralized plant will be more efficient and environmentally friendly. Turbine generators operate much more efficiently than ICEs, large plants can support more thorough and extensive emissions controls and reclamation facilities, they offer a single place for inspection to verify they’re meeting proper controls, and you’re not using even more power to transport tons of fuel to distribution centers all over the place.

There are a lot of external costs and secondary factors that are seemingly being ignored for ICE, and exaggerated for electric.

And I think that the comparative agility of a smaller lighter vehicle is considered part of its primary safety just as the mass of a larger vehicle helps its secondary safety (for its occupants at least).

That isn't intrinsic. Friction forces scale with weight, so if you double the weight of a vehicle, then you double the amount of friction force between the vehicle and the road, allowing the same limiting acceleration.

There are a few complications to this in real life. For speeding up, your limit is usually not the maximum friction the tires can provide but rather the maximum force the engine can produce. High end sports cars are really the only exception there. But for safety, you're usually looking at braking and turning, where the maximum acceleration is dictated by friction. And that maximum force is proportional to weight. It can get more complicated for turning, though, since friction force isn't necessarily the limiting factor. High center of gravity can also limit maximum lateral force to something less than the friction tires can provide. And SUV's (which are heavy) typically have a higher center of gravity than cars, and thus roll easier and can't turn as fast. But it's that high COG, not the increase weight, which is responsible. A heavy sports car with a low COG can in principle turn just as well as a light sports car with a low COG.
 
Anyone buying EVs because they believe that anthropogenic climate change is some kind of real problem, are kidding themselves.
Fail.

How can we take you seriously when you open with a silly statement like that?

First of all, the Lithium ion batteries in Teslas and other EVs are highly toxic. They're known to produce CO gas, and Lithium mining is even more toxic, consumes and pollutes more water, and is more environmentally damaging than fracking.
More fail. The lead in Pb batteries is even more toxic - and there is a lot more of it. Mining of most metals is also highly toxic, as is the extraction and use of coal and other fossil fuels.

However EV batteries don't routinely leak and vent toxic fumes in 'normal' operation like fossil fuels do. Every oil well, tanker, train, pipeline, storage tank, gas station and motor vehicle is a potential and often real source of contamination and/or direct exposure to toxic and carcinogenic fossil fuel products.

But of course you ignore the environmental impact of fossil fuels, because that would weaken your argument.

Second, only a tiny fraction of Li+ batteries are recycled, something on the order of 2-3%.
A worthless statistic. Firstly, almost 50% of the Lithium used in batteries (which is only 40% of total Lithium consumption) goes into batteries used in consumer devices. That most of them are thrown away is not surprising, but this says nothing about electric car battery recycling rates. The vast majority of EV batteries are still in the car, and batteries taken out of junked cars are routinely 'recycled' into other vehicles. Most EV manufacturers warranty the battery for 8 years, and few cars are older than that. I own a first generation 2011 Leaf, which (like most of that age) still has the original battery. I expect to get several more years out of it, but when I eventually need to replace it you can bet the old one will be fully recycled.

But of course you knew this (or should have). You happily lump electric car batteries in with the millions of batteries used in portable electronic gadgets that are thrown away every day because it suits your agenda.

So they decompose in landfills where they pollute the ground water.
Just like everything put into landfills. But you won't find many electric car batteries there.

Third, and most importantly, 80% of the power grid (in the United States, at least) is fueled by non-renewable energy sources (coal, petroleum, natural gas, nuclear, etc...) So all of the virtue signaling EV drivers who like to think highly of themselves for not burning gasoline in an ICE, are still charging their EV batteries from a grid whereby only 20% is powered by renewable energy.
Even more FAIL!

Even if 80% of all electricity generated was from fossil fuels, electric cars could still reduce carbon emissions due their much higher efficiency than IC engines. Many 'virtue signaling' EV drivers are either choosing cleaner electricity sources (which incentivizes producers to install more renewable capacity) or are producing it themselves. Since the US does not have a national grid that combines the output of all sources, where individuals get their power from does matter. And the proportion of 'green' power is increasing, so even if your source is not cleaner now, it probably will be.

And of course (in case you thought you could get away with slipping it into the same category as fossil fuels) nuclear also qualifies for 'virtue signaling'.

Are Electric Vehicles Really Better for the Climate? Yes.
To compare the climate-changing emissions from electric vehicles to gasoline-powered cars, we analyzed all the emissions from fueling and driving both types of vehicles. For a gasoline car, that means looking at emissions from extracting crude oil from the ground, moving the oil to a refinery, making gasoline and transporting gasoline to filling stations, in addition to combustion emissions from the tailpipe.

For electric vehicles, the calculation includes both power plant emissions and emissions from the production of coal, natural gas and other fuels power plants use...

When looking at all these factors, driving the average EV is responsible for fewer global warming emissions than the average new gasoline car everywhere in the US. In some parts of the country, driving the average new gasoline car will produce 4 to 7 times the emissions of the average EV...

Compared to our last analysis that used 2016 power plant data, emissions from EVs are on average 10 percent lower. The reductions have come from two primary sources:

- The emissions rate from power plants in the US fell over 5 percent between 2016 and 2018. The drop comes from lower generation from coal and increases in natural gas, wind, and solar.

- The average efficiency of EVs sold to-date in the US improved since our last analysis (by about 6 percent).

It took me 10 seconds of googling to find that report. Why couldn't you do the same? Of course we both know the reason...

Just because your precious EV doesn't emit CO2 (which is not a pollutant), doesn't mean the power plant that you're charging your vehicle from isn't generating the emissions for you.
See above. You are wrong. Using fossil fuel to generate electricity for EVs produces fewer emissions than burning it in gas cars. And as the grid gets cleaner it gets better. Buy an EV today, and tomorrow it will be even cleaner than it is now.

The two positives that EVs have, is that they are quiet, and electric motors have a lot of torque. But to pretend that you are benefiting the environment by purchasing one, is an exercise in self-delusion.
Some are deluding themselves for sure - but not EV owners.

You keep making unscientific statements, misrepresenting statistics, ignoring facts, appealing to emotion and employing dishonest tricks to justify your refusal to accept change and 'inconvenient' truths. Keep doing it if you like, but we aren't listening. We've heard and debunked it all before, and now we just want to get on with dealing with the problems you say don't exist. And unlike you, we will enjoy rising to the challenge.

It's an interesting question; does a floor-mounted battery pack offset the increased weight and the trend for cars to get taller?
I went from a Nissan Sentra to a Leaf, and immediately noticed the higher seating position improved my ability to see past other cars. This made a huge difference to my driving confidence. With my old car I often felt 'boxed in' by larger SUVs etc., and had trouble negotiating intersections when I couldn't tell if the road was clear. I now understand why people prefer taller vehicles, and would never go back to a car where it feels like I am riding just above the road surface.

The Leaf is a bit heavier than my old car, but with the battery under the floor it seems more stable. Of course it also has many other safety features that my old car didn't have too - like front and side airbags, stronger door pillars, anti-skid braking, no hefty engine trying to land on your lap... The only problem is the slightly longer length and wider turning circle makes it a bit trickier getting into small parking spaces.
 
Result. Thanks to my pestering and my MSP, the car park at home is now on the council list to have electric chargers installed.

I don't believe my state (Hawaii) is the only state that makes electricity with gas powered turbines.

So unless you have PV panels that can power up your EV car, you're charging it up with electricity made from fossil fuels.

Wrong.

First of all, let us not forget that some people on this forum are not Americans, so one cannot discount the possibility that people are charging their cars from Norwegian waterfalls, or French nuclear plants, and the like. But even in the US, there are regions where at least a significant portion of the power used comes from non-fossil sources, including wind, hydro, and non-domestic solar.

The last account I saw of Vermont's electric energy sources, I believe it was 99.9 percent renewable, mostly from Hydro Quebec. We produce only about a third of the electric energy we consume, but of that domestic production, more than half is from hydro.

So here in Vermont, if I were to buy an electric car, the only way I could possibly run it on fossil fuel would be to charge it with my own gas generator.
 
17% of power in the US is generated from renewable sources. That's not a lot but it ain't nothing.

So I'm wrong about how electricity is made in my own state? And that electricity is made from oil/gas?

I wonder when Hawaiian electric company converted their main power plant to Norwegian waterfalls and such?
 
It's largely irrelevant where EV's power is sourced. An Electric Motor is more efficient than an Internal combustion engine, and can be 'powered' from multiple sources.

This will help extend the 'life' of fossil fuels, and help drive improvements to EV technology in the process.
 
You (Joecool) might have meant the "you" in the second sentence of post 1010 as a hypothetical person in the context of the first sentence (Hawaii), but the text looks just the same as if the intended meaning of "you" had been either the individual whom you (Joecool) were replying to (Tippit), or each individual who was reading that post ("you the audience").

It's an ambiguity that I like to avoid by using the hypothetical "one" instead of the hypothetical "you", even though I know it makes me look/sound un-American: "So unless one (in Hawaii) has PV panels that can power up one's EV car, one (in Hawaii) is charging it up with electricity made from fossil fuels."

* * *

(Also I doubt even that sentence's accuracy. It seems odd to me to imagine a tropical volcanic island chain using no other source of electricity but fossil fuels which at a glance would seem to need to be imported, but some of my presumptions in there could be wrong.)

Well....
The state of Hawaii instituted a mandate that 30 percent of electricity generation must come from renewable sources as of 2020. But the state's utilities have already exceeded that figure as they move toward a completely clean energy system.

Hawaiian Electric, the state's largest utility, reported this month that its 2020 generation mix reached 34.5 percent renewable across Oahu, Hawaii Island and Maui. Renewable production rose 13 percent from 2019.

You mentioned Hawaii, but your comment "So unless you have PV panels that can power up your EV car, you're charging it up with electricity made from fossil fuels." did not, as far as I can see, specify that you were speaking about Hawaii.

I take "you" in that context to mean whoever is participating in the thread. If you meant otherwise, I suggest that a bit more clarity would help.

Not forgetting that the stuff powering an ICE car takes massive amounts of energy to extract, refine, and transport.
