Searching for alternative source of fuel to replace existing ones have not been an easy task however what was believed to be future fuels or replacement for the existing ones are now in use.
When we talk about fuels we are simply referring to those things that undergo combustion and produce energy as a result of the combustion. Most fuels are Hydrocarbons, i i.e fuels consisting of Hydrogen and carbon compounds only. This kind of fuels are are also known as fossil fuels and hence can be used interchangeably. Fossil fuels are derived from living matter and these fuels include coal, crude oil and even wood. Remember fuels are anything that undergoes combustion and produces energy in return.
The Burning or combustion of Hydrogen yields carbon dioxide ( CO2). Due to the way in which hydrocarbons are burnt, there have been so much collection of Carbondioxide in the atmosphere. Carbondioxide is responsible for the greenhouse effect or gloabla warming. Global warming is a situation in which the direct heat from the sun reaches the Earth and cannot be radiated back because Carbondioxide acts as a blanket, hence the heat are accumulated on Earth.
The continuous warming of the earth has produced changes in whether. Most of this changes are;
These changes have led to search for alternative fuels which can be used to reduce emission of Carbondioxide.
Wait!
Do you realize how much people have vehicles and considering the fact that vehicles are powered by fuels that produces Carbondioxide, we can decide to tackle global warming by producing cars that don't need hydrocarbons to run.
One possible solution to this problem are the electric vehicles.
Electric vehicles have succeeded as solution for the alternate fuels. This sort of vehicles are powered by battery and gives zero emission. This has earned it the name zero emmission vehicle (ZEV).
A look at this type of vehicle shows that a vehicle with 200- miles-per-battery-charge is capable of handling most travel needs. It could take people to school, the office, and shopping. At night, the batteries could recharged by plugging the vehicle into home electric system. However the problem faced with this kind of vehicles are the increase in electricity usage which can lead to building of new electricity generating plants.
Solar-powered vehiclesA solar cell makes use of semiconductor device to produce direct current-voltage when exposed to sunlight. However the current flows when connected to an external load. This solar can be used to power vehicles. and today it's already in use. The solar panels are placed on top of the cars or any where it can interact with sunlight. However these cars are already in use. The Advantage of this solar powered vehicles over hydrocarbon vehicles are the ability to provide transportation without creating fumes and noise. Total eradication of air pollution and productive of Carbondioxide has been achieved.
