Quote: But in a recent issue of the journal Critical Reviews in Plant Sciences, UC Berkeley geoengineering professor Tad Patzek argued that up to six times more energy is used to make ethanol than the finished fuel actually contains. http://www.sfgate.com/cgi-bin/article.cgi?file=/c/a/2005/06/27/MNG1VDF6EM1.DTL So. Do YOU think that ethanol is a positive choice, or should we try to invest our money looking for a fuel that will bring us closer to energy independence, because right now it seems like we will still be using oil to make ethanol and....well... that doesn't seem to help.

Honestly, the way that we're (The United States) using ethanol is kind of pissing me off. There are way more effective ways to make ethanol, but we want to grow corn... Sugar cane, for instance, is WAY more efficient.
I'm personally pro-solar power. I think ethanol should continue to be researched so that perhaps we'll eventually be able to create it using no oil whatsoever... But I think alternative energy sources are much better. In any case, the one thing we can all agree on, I'm sure, is that we need to make a change, and now.

Just think of the energy that can be harnessed if per se, solar panels were place atop of large buildings in new york. They won't be blocked or in the shade, and could produce energy for the surrounding area.

Biofuel is a great alternative, but as you said, europe and the U.S. don't use it correctly. We use plants such as rapeseed and corn, veggies that can let out more greenhouse gases than Co2. We need to harness the oil of algae. One of the simplest plants to grow, relatively anywhere, and produces more oil than any other plant. All it needs is nutrients, water and sunlight.
