Currently it is not as economical as using fossil based fuels.
For instance, the production of ethanol as a fuel is currently more expensive than the extraction of octane from crude oil.
And also, fossil fuels tend to have a higher heat of combustion (more power).
Mainly two reasons. (1) The fossil fuels will eventually be used up. (2) Fossil fuels cause pollution.
The primary advantage to alternative fuels such as biodiesel in automobiles is to lower harmful emissions into the atmosphere in the hopes of off-setting further damage to the ozone. Currently the biodiesel of choice, at least in the United States, is ethanol derived from corn. There are two affective faults with the current system and crop of choice, first is the amount of ethanol derived from corn is minimal compared to alternative crops such as water based algae. This has a subproblem rooted in that the amount of space necessary to grow the corn to produce sufficient amounts of ethanol is staggering. Secondly, the amount of machinery and vehicles using gasoline or standard diesel in the process of allocating the ethanol from the corn far offsets the benefits of using the ethanol to begin with. Side note - the performance of vehicles on biodiesel is similar to that of standard diesel.
Most of our automobiles today run on petroleum. However, fossil fules are not going to last forever so since last couple of decades there has been tremendous research to find reseasonable alternative to petroleum. Research on biodiesel, synthetic fuels, hybrid fuels hold promising future to conventional fossil fuel alternative.
Fossil fuels were never invented, they were discovered. Some people think that coal may have been used as fuel in prehistoric times.
Electricity, gas, solid fuels
There are many alternative fuels apart from the conventional petrol ,diesel,etc.,.To name them -CNG,hydrogen fuel cell,LPG,electricity,algae oil,etc.,-santa
Any energy source that is an alternative to fossil fuels. They are used to avoid the damages that fossil fuels do to our environment such as: Carbon dioxide emissions which leads to global warming and acid rain.
yes, there are tons of alternative fuels besides oil. i am doing a research project right now in my English class on alternative fuels. so far, i have found biomass fuels, biodiesel, natural gas, alcohol, and french fry oil. hope you can search farther into what you have learned from me....
i think that's she thinks is why do they have to have alternative fuels that's just watse of time
No. Alternative energy means energy sources other than fossil fuels.
Alternatives fuels are fuels that are not made from fossil fuels (coal, oil and natural gas).
Biofuels, Algae fuels ect.
Electricity
Alternative fuels are renewable and produce fewer greenhouse gas emissions compared to fossil fuels, such as gasoline and coal, which are non-renewable and contribute significantly to air pollution and climate change. Examples of alternative fuels include biofuels, hydrogen, and electricity. Overall, alternative fuels are considered more sustainable and environmentally friendly than fossil fuels.
There are several alternative fuels for a diesel engine. Some alternatives include Biodiesel and vegetable oil.
R7 rocketfuel
a source that differs from the most commonly used resource. An example of an alternative fuel is corn oil or sugars, which would replace fossil fuels.
