The carbon-based energy sources which we get from coal, oil, or natural gas are called fossil fuels. On the other hand, biofuels are renewable energy sources. We get biofuels from corn, soy, and other biomass, and all these things can be grown indefinitely.
How are Biofuels and Fossil Fuels Similar?
If we compare the similarity, then
- Fossil fuels and biofuels both are energy sources. We get energy from biofuels as well as fossil fuels.
- Both fossil fuels and biofuels are used to make electricity, and they release waste when combusted.
- When these are used, they both release carbon dioxide into the atmosphere.
How are Biofuels and Fossil Fuels Different?
- Biofuels and fossil fuels are different in many aspects as a biofuel is a fuel that is produced from the living matter, whereas fossil fuels are naturally occurring fuel.
- We get fossil fuels from coal, oil, or natural gas. We obtained biofuel from renewable sources, whereas fossil fuels from nonrenewable resources.
- Biofuel provides a less amount of energy per unit biomass, whereas fossil fuels offer a higher amount of energy per unit mass.
Comparing Fossil Fuels and Biofuels:
As we all know that biofuels are renewable energy sources where they are taking carbon dioxide when they are growing. So, they are carbon neutral.
But fossil fuels are not carbon neutral, and unfortunately, they are contributing to global warming. The good thing is that they are used to generate electricity and to release waste when they are used.
Who has More Efficiency Biofuels or Fossil Fuels?
If we consider the overall efficiency of biofuels vs. fossil fuels, then definitely fossil fuels are more efficient than biofuels. But if we believe biofuels from the environmental point of view, then the answer is biofuels.
Biofuels are better than fossil fuels because, in biofuels, only hydrocarbons are considered, which generate carbon dioxide upon combustion. So, biofuels being environmentally friendly to create the greenhouse effect and also contribute to global warming but less than fossil fuels.
Who is Cheaper Biofuels or Fossil Fuels?
- Biofuels are renewable fuels, and the supply of biofuels does not run out while the number of fossil fuels probably will, after some time.
- So, biofuels are cheaper than fossil fuels, and they are also less expensive. We all know very well that the prices of fossil fuels rise with time.
- For your car engine, biodiesel is better than fossil fuels.
Is biofuel more expensive?
This is the great advantage of biofuel that it is animal-based fuel, and therefore biofuel prices have been falling. So, they are significantly less expensive than fossil fuels or other gasoline. We all know very well that ethanol is cheaper than diesel and gasoline.
Are biofuels a Good alternative to fossil fuels?
Biofuels are better than fossil fuels in the sense that they are not produced by Starving people and destroying the forest because fossil fuels are carbon-based energy sources. Biofuels are renewable energy sources as we get it from the biomass. These can be grown indefinitely. So, biofuels are cheaper than fossil fuels.
Are Biofuels Better than Fossil Fuels For Environment?Â
Both fossil fuels and biofuels are causing global warming, but if we talk about, which is better for the environment than, ultimately, biofuels are better. The benefit of biofuel is that when we burn them, then they put less of the greenhouse gas, carbon dioxide into the atmosphere.
We all know that everything, whether the plants are the animals, is made up of carbon. So, the cycle is going on with the carbon cycle.
Biofuels and Environment:
In biofuels, when plants or their products burn, then carbon dioxide enters into the atmosphere once again. It is a bad addition to the atmosphere but not too much because carbon is continuously recycled.
When the plants are not used as fuel, then they are eaten by the animals. The carbon dioxide again enters into the atmosphere by respiration from the animals.
 Fossil Fuels and the Environment:
We get fossil fuel from oil, gas, and coal containing carbon dioxide, and it was extracted from the atmosphere by plants or animals. But the worst thing about fossil fuel is that carbon dioxide is never released as they did not decay. Instead, they are fossilized. So, when we burn fossil fuels, we are adding more carbon dioxide into the air, thus causing the greenhouse effect.
 Can We Replace Biofuels From Fossil Fuels?
Fossil fuels are polluting our atmosphere. So, scientists thinking of replacing biofuels from fossil fuels. Now, the question arises, that can we replace biofuels from fossil fuels.
However, the main focus is its energy demand that is biofuels fulfill the need for ecological accepted fuels? In today’s market, biofuels are gaining so much popularity as these are the liquid fuel originates from renewable plant materials.
So, if we compare biofuels with gasoline, we see that gasoline is refined from the limited crude oil supplies. Whereas, we get biofuels from several organic sources. The good thing about natural sources is that they are not limited.
One of the main benefits of biofuels is the only renewable energy sector, which is also capable of replacing currently dominant fossil fuels.
Increases Fuel and Food Prices:
- The commercialization of biofuels is difficult because of its cost in comparison to petroleum-based fuels.
- Due to low energy density and the price of raw materials, biofuels become more expensive when it is producing heat.
- When the biofuel content of the fuel is higher, the energy density is lower and therefore energy Efficiency also.
- When we consider the alternative to petroleum, then we also consider EROI (Energy Return On Investment).
We can say how much net energy gain resides in biofuels as compared to the total energy which is used in its production.
