Over the last few years there has been a move towards car fuels that are more environmentally friendly, as conventional fuel creates emissions that are bad for the environment, and health. Many of us already know that there is a real push towards cars being driven by electric motors, but what are the other alternatives?
Here at Source My Car we thought we would give you a short guide to what green fuels are available, and how they are more environmentally friendly.
Petrol – It is important to take a look at petrol and why we need to find other sources to fuel vehicles. Petrol is still used by the majority of motorists, but is one of the major causes of global warming. Petrol engines produce such chemicals as carbon-monoxide, hydrocarbons and nitrogen oxides. As well as causing global warming they also contribute to acid rain, and it is also harmful to human health. As petrol is made from crude oil it is non renewable, which means crude oil will run out at some time in the future.
Diesel – Diesel driven vehicles produce less carbon dioxide, than petrol driven cars, but they do release more volatile organic compounds and nitrous oxides. Diesel cars are 30% more efficient than petrol driven ones, but diesel, just like petrol is produced using crude oil.
LPG – Many of the cars that are powered by LPG in the UK are hybrid vehicles. LPG is much more environmentally friendly than petrol engines as they produce less carbon dioxide, hydrocarbons, carbon monoxide and nitrous oxides. LPG also has the added benefit of causing less wear and tear to a vehicle, and is more fuel efficient.
Compressed Natural Gas (CNG) – CNG is more fuel efficient, and they emit fewer toxic chemicals than conventional cars. Most petrol and diesel powered engines can be converted to run on CNG.
Bio-Diesel – Bio-diesel is a renewable fuel source as it is produced using things such as sugar beet, rape seed, palm oil and sunflowers. Bio-diesel powered cars do not produce toxins, and it does not produce as much damaging exhaust emissions. Bio-diesel is usually cheaper to purchase than petrol or ordinary diesel, and you can even get free bio-diesel if you are prepared to collect the used oil produced by restaurants.
Bio-ethanol – Bio-ethanol is made from renewable energy sources, and although less common in the UK it is gaining popularity in countries such as Brazil. Bio-ethanol is created by the fermentation of certain crops such as sugar-cane in Brazil, and soya-beans in USA.
Electric – Some of the newer cars being built are incorporating electric power sources and running them alongside petrol driven engines. As technology continues to grow so will the distances electric driven cars can go before having to recharge. As electric driven motors do not emit exhaust fumes it could be argued that electricity is the greenest fuel source that we could develop to power cars.
Whether you welcome green sources of fuel with open arms or not, the future for car drivers will mean using better alternatives than petrol or diesel. There will possibly come a time in the future when it will be harder to find a petrol station that actually sells petrol or diesel made from crude oil, than it is to find a local charge point for an electric car today.
We hope that our short introduction to green fuel sources will help you to become a little bit more knowledgeable about the different green fuel sources available to you.
