We have the technology to replace 100% of our transportation fuels with biofuels from algae. You use solar thermal heat pipes to move seawater into the desert, and then grow algae on thermal raceways with solar paddlewheels. The lipids become green diesel and the remainder is processed for Butanol.

Today, parallel gasoline-hybrids are often touted as a cleaner, greener alternative despite the simple fact that avoiding purchasing a new car and sticking with your old one saves more energy and environmental impact in almost all cases. Rather than using the new technology to simplify the vehicle, hybrids are more complicated than their predecessors, and the results are not positive. The added weight of the electrical system means that the vehicle is either unusually heavy, or unusually expensive due to the necessity of balancing weight and crash safety. And the hybrid power system, most especially the batteries, comes at a substantial cost premium as well as substantially increasing environmental impact.

So, I was reading a story on global warming and I found a nice link to a USGS page about volcanic gases.
