Corn Ethanol is an inefficient, environmentally harmful, impractical fuel that will not increase US

First, your counter-arguments. Alright, your first point: basically what I said is that using ethanol decreases the fuel efficiency of vehicles. Most people would generally say that 26 mpg is efficient (many small cars get this), but few would consider 17 mpg to be efficient, since many pickup trucks get higher mpg ratings. Since ethanol has significantly less energy content that petroleum, it is less efficient and is therefore a poorer choice for the United States. Also, it emits more GHG because you have to burn more ethanol than gasoline to get the same power output. Corn, it might seem, is renewable. But it is more expensive than gasoline (due to the high costs of refining, harvesting, distilling, etc.), results in consumers having to but more gallons at the pump, and is economical due to high federal subsidies plus the RFS mandate. Basically, ethanol would not exist without government props. Corn is highly affected by droughts and floods, and if ethanol becomes widespread, a bad growing year would wipe out a large sector of our fuel industry, crippling the economy and making prices at the pump rise. The fact that corn comes from a renewable source does not make it efficient. "Efficient" is defined a producing maximum desired result for a minimal effort with as few undesirable consequences as possible. And since ethanol contains just two-thirds of the energy content of regular gasoline, it does not achieve maximum result with minimum energy, making in not efficient. Ethanol may have benefits to US corn growers, but it will harm all Americans since corn is at the base of the food chain in many ways -- it feeds us directly, it feds many of our meat and poultry products, etc. Increasing ethanol production will decrease corn available for food in every country, resulting in higher prices in many products. With the 'hypothetical situation' I was pointing out that even our tremendous corn production will not make significant dent in petroleum demand. This is not hypothetical, it is interpretation of facts. I have shown that ethanol is inefficient because it produces less energy than traditional fuel sources. I have shown that it is bad for the environment because it uses prodigious amounts of water and land for a very small output. Finally, I have shown that ethanol will not increase US energy security because it can not displace a significant portion of our gasoline needs. My thanks to my opponent for a good debate. (The sources that you requested are : Peter Taylor's book "Chill", the website www.Co2science.org. Try googling graphs of solar (TSI) and oceanic oscillations (AMO or PDO) to temperatures. Additionally, look up www.wattsupwiththat.com or Google Anthony Watts to find examples of egregious temperature measuring station misplacement leading to errors in recording. Note, the last site is a bit hard to navigate, so take your time. Greenland ice core data is also a good search. Most of my data has come from books, so I can't give you too many Internet sites. Patrick Michaels, Iain Murray, and Christopher Horner are other good authors. Hope this helps. Good luck in your debate.)
