As 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.

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 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
had 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.

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 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.

I saw an article recently (can't recall where on the internet) that claimed electric cars were around some time before he gas and diesel powered ones. But there were problems with the distance and recharging of the batteries, the early batteries were not rechargeable, and similar problems to today's. The past to or three decades have proven that with determination and continued research, the gasoline powered engine can be made more efficient and less polluting, but probably never non-harmful to the environment. As for electric automobiles, the change in the infrastructure and increased demand for electricity plus the time constraints for recharging and the limited range of travel and possibly many other problems which likely will arise, it will probably be many years in the future before we figure it all out. Who know, maybe there will be advances in nuclear powered vehicles that will have unlimited mileage capabilities and never need refueling. Maybe fuel cells could be recycled by moving from one old model into a newer one.

EVs aren't especially energy effecient. Battery charging losses are considerable, requiring about 100 watts to store 60 watts. Motor losses are fairly small, yielding around 90 watts out from 100 watts in (very good). Braking regen (battery charging from braking) helps some, but the losses there are significant as well, so perhaps only half of that enery is recovered.

Nothing wrong with exploring and developing EV technology. But its best done as a natural progression as opposed to a forced solution. The latter approach will not yield the best benefits in their time.
