More and more people are looking for alternative fuel sources for practical and environmental reasons. Alternative fuels are seen as more environment-friendly. The gas emissions are less harmful to the environment so they do not add to the problem of pollution, smog, and global warming. People are making the switch to biodiesel, ethanol, natural gas, electricity, hydrogen, propane, and methanol. These are not sourced from fossil fuels which are deemed to be limited resources. Thus, these alternative fuels are sustainable. Another advantage of promoting the use of alternative fuels is that it helps nations become more independent when it comes to energy. This can affect the stability of fuel prices which will benefit the consumers. On the practical side, we all know about the increasing fuel prices. The cost of fuel continues to rise almost on a monthly basis. We are therefore challenged to look for innovative ways to solve our concerns regarding the rising cost of fuel and the harmful effects of gas emissions.

Another alternative source of fuel that is gaining popularity now is waste vegetable oil.  Waste Vegetable Oil is used cooking oil that was made from liquid edible fats obtained from plants. Waste vegetable oil in itself can also contribute to water pollution in our communities if households just throw them down the drain after using it.  If we use waste vegetable oil as alternative fuel, we make good use of it instead of letting it contribute to the pollution and health problem. That is why we are happy to inform people about ongoing initiatives to use waste vegetable oil as alternative fuel. This is made possible through the use of a Veggie Oil Car System which converts vehicles and allows them to run on vegetable oil. It comprises a set of heat exchangers which derive its heat from waste heat from the engine.  They use different surface mount resistor sizes. Vegetable oil in itself is too viscous and its flash point (the temperature at which the fuel becomes combustible or burnable) is too high to be used as a direct diesel fuel substitute.  But by raising the temperature of the vegetable oil, the viscosity is reduced and the temperature is brought closer to that of flash point.  This is made possible by concerned companies whose mission is to search for, develop, manufacture, market, and distribute eco-friendly technologies that will provide alternative means of energy. Some people are hesitant to use it because they are concerned about its effect on their vehicles but those who have tried using waste vegetable oil as an alternative fuel could attest to its benefits its effects on the performance of the vehicles. There are no detrimental effects when you use waste vegetable oil as fuel. It is a good substitute for the commercial fuels that are available in the market.

It is also worth mentioning that aside from waste vegetable oil as fuel, other innovations in transportation and energy currently undertaken are solar powered cars and vehicles that use liquefied petroleum gas.  All these developments revolutionize our transportation and offer not only economic but also environmental benefits.
