Bio fuels are not the answer. Did you know that one gallon of Ethanol is about 85% as efficient as a gallon of regulal gas? Did you know it takes roughly 6 gallons of gas to make one gallon of ethanol today? Did you know that ethanol plants are sucking water supplies dry and they give off high emmissions in the form of carbon dioxide? Did you know that the current plant of choice is corn and corn prices have gone through the roof lately which in turn raises feed prices and thus the price of meat to market? Ethanol is not the answer. It is more of a problem then solution. The only reason ethanol is even made is because of high Federal and State subsidies given to the manufacturers. Without this, the cost would be out of this world.
ADDED: They are looking at other crop options but they all take up land. Corn is one of the most destructive crops available - it takes out so many nutrients but fails to return anything to the ground.
They need to find a better option. There are some promising options out there:
1. Algea - 1 acre yields about 100,000 gallons of oil as compared to corn (6 gallons per acre) and soy (35 gallons). It can also be grown in vertical areas allowing you to grow more per flat acre of land. Since algea thrives off of carbon dioxide emmissions, it can be built next to CO2 emitting plants to help scrub their air.
2. Garbage to oil - there are ways to turn household garbage (mainly plastics) into bio fuels. It is a great idea because it reduces the load going into dumps.
3. Wind - Everyone seems to be worried about whacking a few birds… please, it is either whack a few birds goofy enough to fly into them or we destroy the whole earth. Any questions?
4. Solar - great option for heating water in homes. Can be used as a supplemental option. Need to work on the cost of the panels to make it feasible.
5. Waves - The oceans are always on the move. Great option worth exploring. Low impact.
6. Oil off the coast of Cuba - The commies are not going to come get us. Loose the trade embargo, embrace them, suck their oil dry and ship it directly into the US by pipeline. The Chinese were not stupid - they jumped on it.
7. Hybrids - Great option but currently cost prohibitive. They need to be more affordable. Make Detroit design more fuel efficient cars and trucks.
