Cost to fully charge the Model S from empty: 85kWh battery x 1.15 charging losses x $.10 kWh = $10
Cost to refill my previous Audi from empty: 15 gallons x $4.30 premium = $65
Both go about 265 miles on a full charge/tank, even though the Tesla is larger and faster.
Depends on battery size and electricity price. At 13 cents/kwh costs around 3.5 cents/mile to drive a Model S, more in very hot/cold days. You can do the math for higher/lower electricity costs.
Battery cost has gone down, and will continue to go down, in future years. A new Tesla battery today will not need to be replaced for another 6 - 8 years.
Therefore, the economics will improve for EV's over time.
Fact that @okulawd will not buy a Tesla (either cannot afford it, does not like it, or whatever) is irrelevant. There are 20,000 other people buying the car this year with whatever economics they see this year. These economics will improve in 2014 vs. 2013. And, 2015 will be better than 2014.
If you go to the supercharging stations, it will be free.
If your company offers charging (many do), it will be free.
If you local library offers charging (many do), it will be free.
If you charge in your own garage, it depends on whether you have solar (many do) or not. Solar, pretty much free. Power grid, usually at 25% of the gasoline cost equivalent.
Actually, I know of two companies whose business model revolve around installing charging stations at offices and other places (airport parking garages, etc).
Initially, it's free as part of the the Fed/State credits, but soon that will not be the case (LAX will begin charging for charging so to speak).
25% sounds a little high for the power grid. Where I live, if I use Tesla's calculator a 300 mile charge would cost $7.64 (.09 per kwh). I know this varies throughout the country. For me to fill up to travel 300 miles (which is 3/4 of a tank in my car (Infiniti M35x), is $45-50 (I always use Sunoco Ultra so a complete fill-up from two days ago was $65.00) Price was $3.99.
Sentiment: Strong Buy
