Prince Charles has converted his 38 year old Aston Martin (a 21st birthday gift from the queen) to run on biofuel made from surplus wine. Not only that, he has converted his other vehicles which includes several Jaguars, an Audi and a Range Rover to run on biodiesel fuel made from used cooking oil. These steps have helped him to reduce his travel related emissions by 18 per cent .
we have limited energy reserves (what we call as fossil fuels like petrol, diesel etc). They are not renewable (which means that we cannot replace them). Secondly, they add to the greenhouse effects which harms the environment. So it becomes imperative that steps be taken to reduce our dependence on fossil fuels and switch over to some other means of fuel that is less polluting and reduces the carbon emissions, like bio fuel.
Biofuel can be broadly defined as solid, liquid, or gas fuel consisting of, or derived from, recently dead biological material, most commonly plants. This distinguishes it from fossil fuel, which is derived from long dead biological material.
Biofuel can be theoretically produced from any (biological) carbon source. The most common by far is photosynthetic plants that capture solar energy. Many different plants and plant-derived materials are used for biofuel manufacture.
Biofuels are used globally and biofuel industries are expanding in Europe, Asia and the Americas. The most common use for biofuels is as liquid fuels for automotive transport. The use of renewable biofuels provides increased independence from petroleum and enhances energy security.
