For most other people, however, it remains a challenge to find electric charging stations to refuel.
As a result, sales of electric cars have lagged, with most consumers going for hybrid options that at least offer the possibility of running on gasoline or diesel.
But with interest in going green growing among consumers, and with tougher emissions standards to kick in from 2013 across the European Union, companies are beginning to introduce new solutions.
At this years Geneva Motor Show, several car components firms exhibited portable chargers while others announced deals with major automakers to build more charging stations to ease refuelling headaches.
After all, electricity is the way to go in the future, especially if we want to have zero emission vehicles, Doherty says.
Swiss firm Alpiq E-Mobility AG announced an agreement with Toyota to fit charging infrastructure at its 250 dealers across Switzerland.
In addition, it will also offer a charging station to go with each of Toyotas best-selling hybrid car, the Prius.
It is an an important step toward establishing e-mobility in our country, says Alpiq managing director Peter Arnet.
Another Swiss company, Green Motion, exhibited several types of chargers at the show, ranging from a portable gadget that weighs just six kilograms to a 210-kg installation that looks much like a gas pump.
People will want to charge at home, a spokeswoman for the firm says.
British company Controlled Power Technologies, however, has another solution.
Rather than offering chargers, it showcased an energy booster that would allow a car to run with the same power as a larger one even though it was using a smaller engine.
We offer the economy of a diesel, low C02 emissions and the performance of a two-litre engine at an affordable price, says Nick Pascoe, the companys chief executive.
Despite substituting a 2.0-litre engine on a Volkswagen Passat with a 1.4L motor, the companys booster gave the car greater pulling power while at the same time meeting tougher emission standards, he says.
Instead of adding thousands of euros to the cost, we add tens of euros, Pascoe says.
Manufacturers are progressively having to increase the percentage of cars they sell in the European Union with carbon emissions below 130 grams per kilometre, with passenger cars to meet this level by 2015.
