Earth Day - Biofuel
Yes, it’s Earth Day again. Time to celebrate all things making our world a better place, for us and our kids and our grandkids and so on. And what better way to make the world a better place than to reduce our dependency on dirty nasty oil consumption by using biofuels.
Maybe.

It sounds good on paper. Grow some corn. Make some moonshine hootch ethanol fuel. Mix it in with your gasoline. Now you’re less dependent on oil and saving the planet from evil CO2 emissions.
Well, that’s at least half right. You are using less oil. But while the emissions from your exhaust pipe may be a bit cleaner, and the corn grown may have absorbed all sorts of nasty carbon from the air as it grew, it may not be quite that simple. You see, the process of producing the ethanol also releases CO2 back into the air. It doesn’t make itself. So there’s that amount that has to be counted too. And on top of that, some farmers use artificial fertilizers that are full of carbon, which muck up the Earth-friendly theme just a tad more. And then there’s transporting the ethanol, and so on. The closer you look, the less clean ethanol really is.
But ethanol also has another down side: It’s food! If we had a great surplus of food in the world and no one ever went hungry, then there’d be no arguments. Unfortunately we do not live in such a utopia. And in fact the concern over how biofuel effects food prices is so great that the European Union may even postpone or drop their plans for biosource quotas in motor fuel.
All is not so bleak however. Right now ethanol is produced mostly from corn and sugar. But it need not be so. Algae may provide another, more efficient, means of producing any number of biofuels, ethanol included. Also, while ethanol might be the most thought of and talked about biofuel, we do have others. Biodiesel for example is basically just vegetable oil. It’s much easier to produce and thus better for our environment. And then there’s methanol, or wood grain alcohol, which isn’t made with food crops.
We need to stop overlooking these other alternative fuels and start putting as much research and support into their production as we do into ethanol. Because we really can make the world a better place. If we try.
