Over the last few years, there has been a general move to find cleaner, more energy efficient fuels to run our vehicles. Although alternative energy such as ethanol, Liquid Petroleum Gas (LPG) or biodiesel may not be as widespread as petrol or diesel, they are becoming more and more common, and are generally much cheaper. Not only that, but energy efficient cars and those with low emissions can also qualify for a range of discounts; they attract a lower rate of vehicle excise tax (road tax) and company car tax, and they escape the London Congestion charge.
In this section, you'll find an in depth guide to a wide variety of alternative fuels for cars; some of which are still experimental, whilst others are already being used on the roads.
