Now that gas prices have skyrocketed, oil reserves are low, international relations in the Middle East are shaky, and the North Eastern half of the globe is experiencing a drastic climate change, we as Americans are finally trying to find alternative fuel sources to keep our economy stable and growing.
There are many ideas we may embrace, but the smartest choice would be a source that is biodegradable or will break down without affecting our environment. Some ideas that have been proposed are biodeiesel, hydrogen, methanol, and propane. Propane and methanol do still release some harmful pollutants, but are still much lower than the gasoline operated vehicles. Propane is a more desirable over methanol because methanol has been known to produce a lot of formaldehyde during emissions.
Since those two products still contaminate we should concentrate primarily on biodeisel, ethanol, and hydrogen.
Biodeisel is domestically produced like propane and methanol but unlike them are biodegradable and are produced by renewable fuel. This product still uses fossil fuels but at a much reduced rate compared to propane and methanol.
Ethanol is alcohol based and can also be produced from trees, and grass which is called bioethanol, this fuel is mixed on 85% ethanol and 15% gasoline, but currently is only mixing 10% ethanol and 90% gasoline on cars right now.
Hydrogen can be produced in unlimited quantities and is a renewable energy source that will most likely be considered by the U.S. All these possibilities are being explored by our government but it seems like hydrogen and or ethanol will be the most likely to prevail.
All these energy sources reduce harmful pollutants, are more accessible than oil and cheaper in cost. Maybe we will come to a definite decision or maybe we will embrace more than one source; but one thing is for certain, there will be an alternative source soon.
