Did you know that "55 billion gallons [208 billion liters] of petroleum diesel consumed in the U.S. last year." That's a lot of fuel. Everyone knows that petroleum drives the U.S. economy more then any one single product.
This fact was made evident by Katrina, and fuel shortages that were created soon afterwards. Several news sources are reporting that we have already hit the 'peak oil' production, and its all down hill from here.
Truth is that no matter how you look at it, we need to start cutting back on our consumption, soon rather then later before its too late. If we don't start converting from a petroleum based economy, as they say there will be 'hell to pay'.
I am a big fan of Biodiesel fuels, for a lot of reasons. Its made from renewable resources, it runs cleaner then regular petroleum fuels, and it can run in diesel engines with little or no modifications.
The following article from National Geographic talks about how they're finding cheaper ways to produce Biodiesel fuels, and the advantages of it.
