I'm just going to rant here for a bit...
To be honest, I've never been that interested in the environment because it was never an issue I ran into at home.
Living in L.A., I've never had a close living experience with nature like the most of you guys have had. Conservation and taking care of the environment just wasn't a number one priority for me.
Yes, I did know about the amount of pollution and the growing worry about our energy sources running out, but I never really had a personal problem with it.
I have recently joined the Engineering Microproject Group dealing with Biofuels this semester, and it really is opening my eyes to the tremendous amount of potential we have in working with renewable energy sources.
However, people should not be automatically drawn to these new energy sources. The initial sounds of "zero-carbon emission" and "no pollution" are great, but one must actually research these himself.
The fact remains that the world needs a tremendous amount of energy to run. It is an engine that constantly needs to be fed fuel. The world uses 98 quadrillion Btu every year, and that number is only going to increase as the world's needs increase as well.
Between fossil fuels, biodiesel, and ethanol, the most efficient source in terms of output vs. input is fossil fuels. No matter how good biodiesel sounds, the world cannot purely run on it: It just isn't realistic.
I don't want to end on such a pessimistic note. It is not about "this" or "that." The world needs a happy medium between all the energy sources in order to work at an optimal level.
