At the heart of the biofuels pros and cons debate is the fact that we need a great alternative fuel source as a planet. This source of energy needs to be efficient and able to replace oil as the primary fuel for vehicles and heat. With global warming becoming more tangible for even the biggest skeptics, ethanol and biodiesel seem like the answer to the planets needs. However, manufacturing these sources of energy can have just as big an impact on the planet as emissions from traditional fuels.
Biofuels Pros and Cons
The evident pros of using ethanol and biodiesel is the independence they allow from oil purchased outside the United States. The emissions from direct use in vehicles is also far less than those from more traditional fuels like gasoline. The cons of these energy sources may be more detrimental than the positives are beneficial.
Creating biodiesel and ethanol requires more output of energy in the production phases than the amount of energy created from the fuels. Biofuels pros and cons also take into consideration the large amount of land, corn and soybeans needed to create enough fuel to subsidize the current oil needs of the world.
Currently, the biofuels pros and cons are leaning toward the negatives more than the positives. With new advances in alternative energy production this could swing the other way rather quickly. It is important to keep an eye on current and future plans for research and development of real world energy sources that will eventually replace all oil needs in the world.
