These myths are from the Mother Nature Network:

Myth 1: EVs don't have enough range. You'll be stranded when you run out of electricity.
-- FACT: Americans drive an average of 40 miles per day, according to the U.S. Department of Transportation. Most new battery electrics have a range of at least double that and can be charged at any ordinary electrical outlet (120V) or publicly accessible station with a faster charger.
At present, all it takes is planning for EV owners, who can travel up to 120 miles on a single charge, to use their cars on heavy travel days.

Myth 2: EVs are good for short city trips only.
-- FACT: Consumers have owned and driven EVs for seven years or more and regularly use them for trips of up to 120 miles.

Myth 3: The charging stations must be built before people will adopt EVs.
-- FACT: Most charging will be done at home, so public charging isn't a necessity.
And at least seven companies are competing to dominate the public-charging-station market, and a trade group representing the nation's electric utilities has pledged to "aggressively" create the infrastructure to support "full-scale commercialization and deployment" of plug-ins.

Myth 4: EVs take too long to charge.
-- FACT: The most convenient place and time to charge is at home while you sleep. Even using the slowest 120-volt outlet, the car can be left to charge overnight, producing about 40 miles of range.
Most new battery cars and plug-in hybrids will charge from 240-volt outlets providing double or triple the charge in the same amount of time. Charging stations that reduce charging time even more are beginning to appear.

Myth 5: Plug-ins are too expensive for market penetration.
-- FACT: New technologies are typically costly. Remember when cell phones and DVDs were introduced? Also, the government stimulus package includes a $2,500 to $7,500 tax credit for EVs and PHEVs. Some states are considering additional incentives ($5,000 in California and Texas).
And EVs require almost no maintenance or repair: No oil or filter changes, no tune-ups, no smog checks.

Myth 6: Batteries will cost $15,000 to replace after only a few years.
-- FACT: The battery is the priciest part of a plug-in, but costs will drop as production increases. The auto industry is expected to be purchasing up to $25 billion in advanced batteries annually by 2015. Some car makers plan to lease their batteries, so replacement won't be an issue.

Myth 7: EVs just replace the tailpipe with a smokestack.
-- FACT: Even today, with 52 percent of U.S. electricity generated by coal-fired power plants, plug-in cars reduce emissions of greenhouse gases and most other pollutants compared with conventional gas or hybrid vehicles. Plug-ins can run on renewable electricity from sources such as the sun or wind.
Plug-in hybrids will reduce greenhouse gases and other emissions, even if the source of electricity is mostly coal, a 2007 study by the Electric Power Research Institute and NRDC showed.
