Ten years ago there was hardly anyone interested in this idea at all. Although there were only ever two cars made like this at the start and neither of them saw many purchases the companies saw the potential and you can see the benefits now.

Although a hybrid does emmit less C02 than a normal car it is a long way off from emitting no C02 altogether which is why it is only at its first stage.

The propulsion systems that completely eliminate tailpipe emissions include hydrogen-powered fuel cells and the battery-powered electric motor, but both face significant hurdles before they can compete with conventional cars.

Something that has turned out to be better is the electric car. Like a fuel-cell vehicle it produces no tailpipe emissions and little noise, and the distribution network for its energy source largely exists taking electricity the final few metres to a charging post is nothing compared to establishing a hydrogen infrastructure.

Instead, electric cars are limited, literally, by battery technology that today allows a modest city car a range of no more than 80 to 100 miles compared to the 300 miles-plus of a conventional car.

100 miles is more than enough for most small journeys which is why these cars are great if you live within a city but if you do not then bad luck. Which is why General Motors’ “range-extending” Vauxhall Ampera (aka the Chevrolet Volt) offers a promising compromise when it goes on sale in 2012.

The great thing about this car is that for the first 40 miles the car actually runs on electricty alone which of course is more than enough for someone living in the city.

The ease of recharging it, and pure electric cars, is likely to be improved by policies intended to encourage electric car ownership. The present Government talks of incentives of up to £5,000, while London mayor Boris Johnson aims to make the capital a lead city in the adoption of the electric car.

However until such a green car comes out that is actually worth going after something a bit less greener so why not look into the new Audi or of course a Audi TT Roadster

Failing this you could even look into getting Used Cars however it is really up to you on what you do on this but I would say the best thing to do is just wait and see if things are actually going to get worse before you do anything.
