"Biofuels will even curb greenhouse gases"
HOW???
You are still oxidizing carbon when you burn a biofuel. I don't see how biofuels will alter the so-called carbon footprint. ALL the energy comes from the exothermic bonding of Carbon to Oxygen.
Any FReepers got better ideas?
and don't try to tell me that hydrogen gas is a bio fuel ...
I guess when a sentence is like this is stuck in the middle of an article it means that man made global warming is an accepted fact.
The carbon dioxide that's put into the air by burning biofuel is recycled by the plants that are used to brew the next batch of biofuel. By contrast, burning fossil fuels puts CO2 in the air that wasn't in the carbon cycle before.

When we burn fossil fuels, we are liberating carbon that has been locked up for eons. When we burn biofuel, we are liberating carbon that was just recently taken from the atmosphere. It's called recycling.
Fuels comprised of shorter hydrocarbon chains carry more of their energy as Hydrogen. The ratio of H/C goes up as the length goes down.
As others have pointed out, biofuels are derived from the current rather than prehistoric carbon cycles. Unfortunately the world appetite for energy has the capacity to completely overwhelm the natural carbon cycle. We would have to denude the planet several times over on a regular basis in order to replace fossil fuels.
Another point missed is that transferring combustion of Carbon to combustion of Hydrogen is a completely wrong approach if you buy into the opinion that significant anthropogenic global warming is occurring. Water vaporor is a more powerful greenhouse gas than CO2.
With that said, I like biofuels, I'd like to see or create an enabling technology that will allow individuals to exploit various niche sources as they may be available.
Don't fool yourself, the left isn't interested in reducing oil use for the purpose of saving the environment. Worship of the environment is a leftist scheme to reconstruct society and world economics.
