| I started this post just to point out that oil companies, opec, and the paid off government are more interested in keeping us in their pockets than starting on a real solution that does not promote global warming or require wars. Doesn't anyone else care? | |

Replying to: gagrice (Apr 11, 2006 7:07 pm) While I believe instead of stating it takes 1 barrel of OIL you could say it is a positive process of using 1 barrel of ethanol to make 1.21 barrels of it (hence the positive aspect of it). And is that number only from corn which isn't the best for this? But I'll read the biodiesel article now.

| While biodiesel does seem like an OK alternative to gasoline, it is still a very bad source of greenhouse gases. It produces only 10% less carbon dioxide then gasoline but more of the smog producing nitrogen oxides. Not a great alternative, but certainly something that should have been in use all along. | |

Replying to: hfish1212 (Apr 11, 2006 7:20 pm) Biodiesel is GHG neutral as is Ethanol. I am all for alternatives as long as they are legitimate and not more corporate welfare. I just do not see any of our small farmers being helped by ethanol production. Maybe a small farmer will jump in and correct me. If there is a conspiracy I would suspect ethanol as much as MTBE. Neither one benefits the environment as much as it is touted to. I am eagerly waiting for good solutions before I give up my fossil fuel burning vehicles. Keep the faith!

Replying to: gagrice (Apr 11, 2006 8:35 pm) Now I am in agreement that no one alternative needs to be the only solution. Hydrogen seems ridiculously expensive to implement but it might work in small scale. Ethanol, certainly won't become the 100% solution like in Brazil but is very usefull in blends. Biodiseil, a good win and might be best for trucking. You wait, the new nano lithium by Toshiba (think 1 minute/90% charge time) will really boost electric vehicles and may just appear to come from nowhere and dominate.

Replying to: hfish1212 (Apr 11, 2006 9:45 pm) Ethanol is not GHG neutral because there are CO2 generating energy inputs required for cultivation, fermentation and purification. Currently these energy inputs are being supplied by fossil fuels. If you imagine these energy inputs being supplied by ethanol, you see how efficiency is conflated with GHG neutrality to make these biofuels seem better than they are. The idea is that all the carbohydrates in the corn came from CO2 in the atmosphere and so when they are oxidized there is no net increase in CO2. Suppose you have 100 acres in corn, the kernels are going to be used to produce ethanol for fuel, and all energy inputs are supplied by ethanol from a previous harvest. Some of the ethanol from the current crop must be set aside to be used for energy inputs for the next harvest. It is true that this produces no net increase in CO2, but there is not enough available arable land to supply all our energy needs this way, unless we greatly reduce our energy consumption. |

If people started using that in mass there would be very little to go around. switch grass can be used and it would be closer to 341% vs 21% of corn . Its also much easier to grow and uses less toxic chemicals. BIodiesel wont likely work. The amount created would never keep up with the demands of the consumers . |

Which raw material can produce the most gallons per acre per year,  Corn, Sugar Beets, Sugar Cane, Apples, Oranges, Grapefruit, some other type of fruit, vegatable or other plant life? How will the choice of raw material impact the current market (non-ethanol uses(food, plastic, clothing, etc.))? |
