Pros and Cons are many eco-benefits to replacing oil with bio-fuels like ethanol and bodies

There are many eco-benefits to replacing oil with bio-fuels like ethanol and bodies. For one, since such fuels are derived from agricultural crops, they are inherently renewable-and our own farmers typically produce them domestically, reducing our dependence on unstable foreign sources of oil.
Additionally, ethanol and bodies emit less particulate pollution than traditional petroleum-based gasoline and diesel fuels. They also do not contribute to global warming, since they only emit back to the environment the carbon dioxide (CO2) that their source plants absorbed out of the atmosphere in the first place.
And unlike other forms of renewable energy (like hydrogen, solar or wind), befouls are easy for people and businesses to transition to without special apparatus or a change in vehicle or home heating infrastructure-you can just fill your existing car, truck or home oil tank with it.
Those looking to replace gasoline with ethanol in their car, however, must have a flex-fuel model that can run on either fuel. Otherwise, most regular diesel engines can handle bodies as readily as regular diesel.
Despite the upsides, however, experts point out that befouls are far from a cure for our addiction to petroleum. A wholesale societal shift from gasoline to befouls, given the number of gas-only cars already on the road and the lack of ethanol or bodies pumps at existing filling stations, for more detail www.jointwebventures.com would take some time. Another major hurdle for widespread adoption of befouls is the challenge of growing enough crops to meet demand, something skeptics say might well require converting just about all of the worlds remaining forests and open spaces over to agricultural land.
Replacing only five percent of the nations diesel consumption with bodies would require diverting approximately 60 percent of todays soy crops to bodys production, says Matthew Brown, an energy consultant and former energy program director at the National Conference of State Legislatures. Thats bad news for tofu lovers.
Another dark cloud looming over befouls is whether producing them actually requires more energy than they can generate. After factoring in the energy needed to grow crops and then convert them into befouls, for more detail www.easy-jv-manager.com Cornell University researcher David Pimentel concludes that the numbers just dont add up. His 2005 study found that producing ethanol from corn required 29 percent more energy than the end product itself is capable of generating. He found similarly troubling numbers in making bodies from soybeans. There is just no energy benefit to using plant biomass for liquid fuel, says Pimentel.
There is no one quick-fix for weaning ourselves off of fossil fuels and the future will likely see a combination of sources-from wind and ocean currents to hydrogen, solar and, yes, some use of befouls-powering our energy needs.
The elephant in the living room, however, that is often ignored when considering energy options is the hard reality that we must reduce our consumption, not just replace it with something else. Indeed, conservation is probably the largest single alternative fuel available to us.
