The Efficiency of Biofuels
Biofuels are alternative energy sources produced from plants like corn, sugar cane or other crops. It is explicit that biofuels which are used to meet our energy needs will become major contributors to energy supply in the modern world, but there has recently been a debate over its benefits. The question is: will they help us overcome the disadvantages of fossil fuels?
First, ethanol is a fuel made of plants which can reduce pollution in cities because it produces fewer emissions than fossil fuels. This means they are cleaner than gasoline and friendly to the environment. This fact supports the idea that biofuels should be used more to replace fossil fuels and to reduce the pollution caused by fossil fuels. However, this does not mean that they will not contribute to the air pollution in cities because ethanol is less efficient than gasoline. Less energy is produced out of ethanol than the same amount of gasoline. To be more precise, if you are using biofuels instead of fossil fuels you burn more fuel to travel the same distance.
Next, biofuels are renewable fuels and they will not run out like fossil fuels. We can always grow plants as long as there is enough agricultural land. However, growing more plants for biofuels is a controversial issue because vast amounts of land and water are needed to produce oil. If we consider the land availability for the production of biofuels, we can see that we do not have enough agricultural lands as they are being used to meet the demand for food. Biofuel production has also raised food prices. This has encouraged researchers to develop new technologies to reduce the effect biofuel industries have on food production and cost.

Precise! I think there's more to be done in this field otherwise, we have to consider improving on other resources like the solar.

I hope so :) Thank you for the comment THarman7.

Great hub, lets hope they find a cheaper way to fuel our cars soon!

Yes, I definitely agree with you. Thank you for your comment Chad Chering.

Interesting hub, I think Bio fuels will be a thing of the future.
