Ethanol is made from corn and sugar cane, ect, and is a renewable source of energy (unlike oil). Obviously, it's also in the alcohol we drink. E85 is made up of 85% ethanol (made from corn, grass, and algae in this country) and 15% petroleum. That means that 85% of what you burn as fuel is clean and 15% is harmful, as oppose to the 100% harmful fuel found at your local gas station. Now, granted, E85 has a lower energy-output than pure gasoline. This means, theoretically, that you would have to fill up your fuel tank a bit more often than you would on E85 than gasoline, but not nearly more often enough to off-balance the positive gains on clean burning fuel. Also, it is true that at least in this current moment, it takes so much power and manufacturing to make ethanol, that we are still polluting the earth just as much. It isn't green neutral, yet, but it will be and then some in the near future. There are plants coming online (one in Arizona I believe for sure) that are completely fuel-efficient, 100%, and renewable based upon an extremely high-energy yielding algae. This algae is so dirt cheap and easy to grow (all it needs is any sort of water and sunlight) and holds so much energy that not only can these plans export their ethanol for fuel, but they even power the plants with it!!!! Completely. There is no energy-loss whatsoever and not a single pollutant. It might not be a perfect solution right now, but ethanol technology is in it's infancy and once we crack more innovations like algae, it will quickly catch up to being less expensive, completely renewable, and nearly completely clean for the environment.

as for the algae, it is in the very beginning of figuring out the processes, and so far it hasn't been shown to be 'green' either. there seem to be some pollutants that are let out in the manufacturing process, but then again, industrial wind farms aren't green either, just 'clean' i suppose. A more responsible choice would be to stop using so much energy all together, but no one will take a REAL step. |

Although, It is already too late. I don't even care if global warming doesn't exist, there are other ways in which using so much energy is extremely dangerous. Just the web of electrical wires that flow throughout your house is extremely dangerous to the people who sit within it all day. And then, when you aren't there you are at work, in the same situation. |
