This has been around, but it needs to keep looping so that folks understand the issues associated with electric cars.

Engineers Take on Electric Cars

Interested in what the engineers or others with knowledge and/or experience in this field have to say about this man's comments. it was sent by a friend.



As an engineer I love the electric vehicle technology. However, I have been troubled for a long time 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.

IF ELECTRIC CARS DO NOT USE GASOLINE, THEY WILL NOT PARTICIPATE IN PAYING A GASOLINE TAX ON EVERY GALLON THAT IS SOLD FOR AUTOMOBILES, WHICH WAS ENACTED SOME YEARS AGO TO HELP TO MAINTAIN OUR ROADS AND BRIDGES. THEY WILL USE THE ROADS, BUT WILL NOT PAY FOR THEIR MAINTENANCE!
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.

At a neighbourhood BBQ I was talking to a neighbour, 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
had to face certain realities. For example, a home charging system for a Tesla requires a 75-amp service. The average house is equipped with a 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.

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. Simply put, 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.

My Take:
It’s always “Free Beer Tomorrow” – never “Today”

Who pays $1.16 / Kwh ?

So some engineer in Canada is the brain trust on the negatives of electric vehicles?

The only thing in that article I agree with is... “ IF ELECTRIC CARS DO NOT USE GASOLINE, THEY WILL NOT PARTICIPATE IN PAYING A GASOLINE TAX ON EVERY GALLON THAT IS SOLD FOR AUTOMOBILES, WHICH WAS ENACTED SOME YEARS AGO TO HELP TO MAINTAIN OUR ROADS AND BRIDGES. THEY WILL USE THE ROADS, BUT WILL NOT PAY FOR THEIR MAINTENANCE!‘

The thing that always makes me laugh is the "green" production of the batteries and when they go ka-poot, the "green" recycling..er, disposal of the batteries.

When cost analysis is added in, the break even point for cost savings usually shows a break even point around 6-8 years, depending on how much you drive and how expensive electricity is. My understanding is the tesla batteries have a lifetime warranty, doesn't mean you will have them for the rest of your life they just aren't going to charge you for new ones. But the batteries on my parents prius lasted less than 200K miles and around 9-10 years. Even not paying for the new batteries, the "green" aspect starts over essentially every time you change out the batteries.

I recently priced out solar for my place in OK. The company offered a 10 year loan that would essentially offest the cost savings for the solar install and equipment. I have done enough research to know the average battery bank is going to last around 10 years (this was with teslas powerwall or similar, not your more typical off grid 24V AGM battery set up which will last 5-7 years max)...so their scam is setting you up for a lifetime of payments, regardless of who you are paying, just shifting the payments from electric to a solar installer company. No cost savings there.

The only way the numbers work for green energy is if the Dems drive up fossil fuel costs....and they do try.
