At a neighborhood BBQ I was talking to a neighbor, a BC Hydro Executive. I asked him how that renewable thing was doing. He laughed, then got serious.
If you really intend to adopt electric vehicles, he pointed out, you have to face certain realities. For example, a home charging system for a Tesla requires 75 amp service. The average house is equipped with 100 amp service On our small street (approximately 25 homes), The electrical infrastructure would be unable to carry more than three houses with a single Tesla, each. For even half the homes to have electric vehicles, the system would be wildly over-loaded.

Why a 100 amp service? Unless you have a small 1-2 bedroom "starter home" most houses built in the past 30 years have at least a 150 amp service if not a 200 amp service.

I admit that I copied and pasted this from another individual far more insightful than myself but you'll have to admit that the writer's point is well made.
Enjoy!

**************************************************************
I'm an engineer & I love the electric vehicle technology.
However, I have been troubled for a longtime by the fact that the electrical energy to keep the batteries charged has to come from the grid and that means more power generation and a huge increase in the distribution infrastructure.
Whether generated from coal, gas, oil, wind or sun, installed generation capacity is limited.
A friend sent me the following that says it very well.
You should all take a look at this short article.


If electric cars do not use gasoline, they will not participate in paying the tax on every gallon of gas that is sold for automobiles, which was enacted years ago to help maintain our roads and bridges.
The electric cars will use the roads and not pay for their upkeep!

In case you were thinking of buying hybrid or an electric car: Ever since the advent of electric cars, the REAL cost per mile of those things has never been discussed. All you ever heard was the mpg in terms of gasoline, with nary a mention of the cost of electricity to run it . This is the first article I've ever seen and tells the story pretty much as I expected it to.

Electricity has to be one of the least efficient ways to power things, yet they're being shoved down our throats. Glad somebody finally put engineering and math to paper.

This is the elephant in the room with electric vehicles. Our residential infrastructure cannot bear the load. So as our "genius" elected officials promote this nonsense, not only are we being urged to buy these things and replace our reliable, cheap generating systems with expensive, new windmills and solar cells, but we will also have to renovate our entire delivery system! This latter "investment" will not be revealed until we're so far down this dead end road that it will be presented with an 'OOPS...!' and a shrug.

If you want to argue with a green person over cars that are eco-friendly, just read the following. Note: If you ARE a green person, read it anyway. It's enlightening.

Eric test drove the Chevy Volt at the invitation of General Motors and he writes, "For four days in a row, the fully charged battery lasted only 25 miles before the Volt switched to the reserve gasoline engine. Eric calculated the car got 30 mpg including the 25 miles it ran on the battery. So, the range including the 9-gallon gas tank and the
16 kwh battery is approximately 270 miles."


It will take you 4.5 hours to drive 270 miles at 60 mph. Then add 10 hours to charge the battery and you have a total trip time of 14.5 hours. In a typical road trip your average speed (including charging Time) would be 20 mph. According to General Motors, the Volt battery holds 16 kwh of electricity. It takes a full 10 hours to charge a drained battery. The cost for the electricity to charge the Volt is never mentioned , so I looked up what I pay for electricity.

I pay approximately (it varies with amount used and the seasons) $1.16 per kwh. 16 kwh x $1.16 per kwh = $18.56 to charge the battery. $18.56 per charge divided by 25 miles = $0.74 per mile to operate the Volt using the battery. Compare this to a similar size car with a gasoline engine that gets only 32 mpg. $3.19 per gallon divided by 32 Mpg = $0.10 per mile.


The gasoline powered car costs about $25,000 while the Volt costs $46,000 plus. So the Canadian Government wants loyal Canadians not to do the math, but simply pay twice as much for a car, that costs more than seven times as much to run, and takes three times longer to drive across the country.



And NONE of this discusses the disposal cost of the batteries once they are used up and need to be replaced!!!




Where to start?

Where on earth does this "engineer" Get his electricity ??

He pays $1.16 a KWH?? Bull.

The 1st gen Volts never use more than ~10.4 KWH of their battery either, therefore a charge in KWH is less than what he quoted also.

Here, a 2nd gen Volt will cost about $1.50 for a full charge from a depleted state and that is for ~53 miles range on battery only.

No mention of the type of charger either, no way that is a 240 VAC charger. 240 VAC charge from empty takes about 4 hours.

rant over.

I do agree the gas tax is a legitimate concern as more and more electric vehicles hit the road.

ps. In the last 2 weeks a 2017 Volt was purchased by a family member and I was able to take it out for a good drive.
Very nice car and my only complaint is that for people with arthritis getting into low slung vehicles would get old, other than that a very impressive machine.
Also 1st trip back from the dealership netted 44MPG @ 75 miles an hour with 0 battery charge- since Car Max forgot to plug it in.

If diesel fuel for the trucking industry were to hit $4 a gallon of some period of time it may drive more sales of the Class 8 electric trucks coming on to the market soon.

Biggest change in fuel since leaded gas went away could raise prices

While we have been reading posts about EV's are dying on the vine because they are not based on good science it seems 8-10 companies around the world are making electric semi trucks to move freight without using diesel.

I wonder how long it will be before Dodge Ram comes out with an Cummings electric motor instead of a Cummings diesel?

All the companies besides Tesla that are building future semi-trucks

The big truck makers are starting to take electric trucks seriously | GreenBiz

"CEO of Daimler Trucks, Roger Nielsen, declared that the beginning of the post-internal combustion engine era for commercial vehicles is here. For commercial trucks, "the road to emissions-free driving will be driven by battery electric vehicles," Nielsen said."

Locomotives are diesel-electric hybrids. Just as a Prius is a gasoline-electric hybrid, only the Prius also has a relatively small battery and the locomotive not.

IIRC a modern locomotive is rated 425 miles/gallon/ton of freight.
A diesel electric locomotive is not a hybrid.

in order for a class 8 truck to be driven 10 hours . More than half of the payload weight and volume would be taken up by batteries .
How much are you saving on fuel costs to make up for only hauling half a load .
What is the electrical source to power all those 300Kw chargers for every truck in every truck stop and trucking company yard .
How is that truck going to pay for it’s self when it has to spend 8-10 hours a day charging .

Here you go, Gale. This Chevy Bolt is said to have made it all the way to Florida from NY.

From the plate it seems the car is headed home.

It states it is solved and the comments have been closed but I have yet to find the SOLVE post. Did you ever solve it?

One of the pictured EV for trucking states a range of 213 miles. What kind of truck driver takes 10 hours to drive 200 miles?

Wow- Gale had not heard anything about the switch in bunker fuel to lower sulfur content.

Looks like it is causing some issues with the barges having the tanks cleaned prior to carrying the cleaner fuel.

Tankers running on fumes as shipping fuel switch causes delays - Reuters

I never thought about it but I bet the build up in the tanks could be huge after 20-30 years of hauling high sulfur oils.

If the rules for a ship out in the middle of nowhere are getting that tight on pollution I think most can grasp the ICE in cars and even semis are going the way of the doo doo bird over time.

Unsolved. I saw that described in the off-topic section of ChevyBolt forum then followed a couple of links that said it was seen in Florida with NY plates. That's all I know.
