A friend emailed this article. I am not sure if data is right, but thought it would make for a good discussion.
Interesting Take on Electric Cars
This is for Engineers out there, surely there should be a rebuttal to this article. Say it isn't true!
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.& nbsp; 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.
INTERESTING - ONE OTHER QUESTION. 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 MAINTAI N OUR ROADS AND BRIDGES. THEY WILL USE THE ROADS, BUT WILL NOT PAY FOR THEIR MAINTENANCE!
In case you were thinking of buying 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 B C 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 veh icles, 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 sys tem! 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.&nbs p; T hen add 10 hours to charge the battery and you have a total trip time of 14.5 hours. I n 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 m ile.
The gasoline powered car costs about $20,000 while the Volt costs $46,000-plus (($8,000.00 subsidized by you!) So the American Government wants loyal Americans not to do the math, but simply pay three times 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.
Article from Automobile magazine:
The Tesla's and other vehicles like them are basically luxury commuter cars. You take any trips with them, it takes 3-4 times as long due to charging.Read an article in one of the car magazinesrecently which talked about one of the writers taking his family on a summer trip with his family in a Tesla Model X <image001.jpg>
from Connecticut to Virginia Beach, VA, normally an 8 hour drive. He did it just to write about his experience.... It took him 2 full days, one way due to charging stops.. Needless to say, it wasn't fun. Disposable transportation for $125K.....
