Electric Vehicle Myths
Electric Vehicles:
- are a passing fad
- need new batteries every few years
- will bring down the power grid
- have the same net carbon emissions
- have a higher life cycle cost
- catch fire and explode

Electric Vehicle Advantages
- environmental benefits - no emissions
- low operating cost - typically 15% of the cost
- no oil changes
- 98 % fewer moving parts
- virtually no brake pad replacements
- expected twice the useful life of ICE vehicles
- anti “big oil”
ICE = Internal Combustion Engine3

Electric Vehicle Operating Cost
Current Fuel Expense (at $1.35/litre)
Fuel Cost/litres X 235.215Average miles per gallon
= $Cost/100 km
Electric “Fuel” Expense (at 0.11/kw-hr)
Nissan Leaf = $1.65 / 100 km
Tesla Model S = $2.50 / 100 km
$1.35 X 235.21528.6 miles per gallon
= $11.10 /100 km
Example Honda Civic 2.4L
Kw-hr per 100 km X Hydro Cost
15kw-hr / 100 km X 11 cents/kw-hr
Plus oil changes

Table Look Up Method
Example:A vehicle getting 25 mpg with a fuel cost of $1.30 /litre would have a fuel cost of $ 12.23 per 100 km
