There are many innovative solutions to the current questions concerning high gasoline prices and greenhouse emissions. Crops grown especially for fuel. Ethanol made from corn has no harmful emissions it is made from a reusable resource, the US government is pushing for 80% bio-fuel mixed with 20% gasoline, they can better than that! Bio-fuels produced from crops such as soybean and corn are at an effective alternative to gasoline both being a renewable resource that helps the farmers have a constant demand for their crops all the better for a continuous cash flow. However, if all the corn currently grown in the US was used to produce ethanol it would only meet only around 12% of the current demand for fuel, more and more land is being bought up for the production of ethanol, and it’s largely dependent upon the weather, a yield of around 18 gallons of oil from corn can be produced per year per acre, more can be possible with genetic alterations, the growing process also requires fertilizes, pesticides and heavy machinery to harvest, effectively adding to soil contamination. It is also estimated the process uses as much energy to produce and transport as regular oil. There are also concerns that the farmland required for producing ethanol from crops will take up valuable space previously used for food crops, as recently food crops have suffered from extreme weather conditions and natural disasters pushing food prices higher, is then using this land, to produce ethanol feasible or even ethical?
Other alternatives being looked at are probably more efficient but less appealing to some, include reusing vegetable oil, a converter with filter, which can be placed in any diesel engine to allow it to take 100% used vegetable oil such as that from restaurants, it is refined slightly after being collected, and then sold at less than half the price of regular gasoline, higher end cars such as Saab and Mercedes are using this technology.
