Thinking about switching to an electric car?  Read this:
Car buffs thinking of changing cars, read this.
Just for your information.
I always wondered why we never saw a cost analysis on what it actually costs to operate an electric car. Now we know why.
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 3 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 the damn 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. 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 1/2 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 $15,000 while the Volt costs $46,000........So the American Government wants loyal Americans not to do the math, but simply pay 3 times as much for a car, that costs more than 7 times as much to run, and takes 3 times longer to drive across the country.....

It think your friend didn't think this thru.  We charge at night and aren't usually running our electric full out using the entire 100amps of the panel.  I have a 2013 Smart ED and charged it the first two months on a 120volt outlet, 20amp breaker. Upgraded to 240V Eaton evse on a 40 amp breaker because it charges much faster and we can get more use out of the car during the day. The evse puts out 7.2 kw max which my car  uses just less than half of.  I choose it in 2013 as it was the highest capacity at a  reasonable price and I wanted to future proof if I would ever buy a bigger electric vehicle. It will charge a Tesla overnight without problem.  It uses less electricity when charging than an electric clothes drier.  We use a clothes line by the way, changed our fluorescent bulbs to led, replaced one old window air conditioner 12,000 btu and cut that a/c's usage alone from 1335 watts (9.8eer) to 957 watts (12eer). We cut our electric bill compared to pre-electric vehicle.  We use less electricity 4 years after buying the electric car than before.  The future is in efficiency. Every appliance replaced due to wear and age frees up more capacity.   

Not everybody requires a 75 amp Tesla style speed evse and if most charging is overnight the electric grid can handle it. 

As far as cost, I live in NJ, the max. residential rate is 18 CENTS, that's $.18 per kw.  summer time with everybody using air conditioning and maxing out the utility.  I divided my electric bill charge by kw used to arrive at $.18.   I can drive anywhere from 70 to 95 miles in the summer using from 80% to 99% of battery charge, for less than $3.18.  That is $3.18 to fully charge the Smart's 17.6kw size battery from ZERO. Normally charge every night and add back 30% to 40% that we used that day.  That's 2 hours charging to get 40% back into the car.  Weekends we'll use 80% to 120% in a day (charging in-between during the day).  Much cheaper to fuel than my gas car at 24mpg and today's price of $2.79 gallon for regular grade gas.
