Nowadays, the price of petrol is increasing resulting in higher daily life expenses and it seems not to be resolved soon. However, there's an alternative fuel that is cheaper and is used ubiquitously in many motor vehicles especially in taxi. Yes, it is LPG or liquefied petroleum gas that is used as a fuel for cooking appliances, heating devices as well as vehicles. Using LPG in motor vehicles is not new. It has been used for at least three decades and many car manufacturers include the bi-fuel system, meaning that you can use either petrol or LPG, to their certain models. However, many cars are not LPG enable and you may have to modify the fuel system yourself. This is the hidden expense for users that want to switch to LPG.
In Australia, because of much cheaper price of LPG (less than half of the gasoline price), the government has launched a scheme for LPG switching. It grants money for up to AU$2,000 for the use of LPG in motor vehicle, encouraging people to consider switching to LPG. The scheme will allow AU$1,000 to a person that decides to purchase a new LPG vehicle for private use and AU$2,000 to a person that wishes to convert the fuel system of his or her existing vehicle. Of course, you have to apply to the scheme in order to receive the allowance.
This is the example of the government that has something good to do. In contrary, the government in a certain country does not try to encourage people to use an alternative fuel like this. Also, it tries to offer a lower quality (NGV) fuel which is not much cheaper than LPG and build the image that LPG is dangerous while gaining profit from LPG as a cooking fuel. You know what I mean...
The Brazil government is also a very good example in encouraging people to consider an alternative fuel. They use alcohol! Most of motor vehicles in Brazil use alcohol and I think that there're very few gas stations selling petrol.
