Nate, bio-diesel is one way, but you still are increasing the CO2 emissons (the "Inconvient Truth" is that our CO2 emissions today are higher than at any time on earth... Out stipping the CO2 level that were around during the Carboniferous period the fossil fuel reserves were first being created. CO2 emissions are what are driving the climate changes that are melting the polar ice. The NOAA weather observatory on Mauna Loa has taken CO2 levels since 1958. Every year has shown an increase in CO2 levels, rising in an exponential pattern. Every time anyone burns any carbon based fuel, are atmospheric CO2 levels rise. The traditional CO2 sinks (the ocean & plants on earth) are showing signs that indicate that they are being adversely effected by the increase in CO2.
It would be far wiser to utilize technology that does not burn carbon based fuels for energy (PV panels on all south facing HI buildings is a very pratical start to limiting our CO2 contribution to the atmosphere). The new Island Naturals Pahoa store with the SunEdison array is a great way that corporations can work together on this.
Utilizing bio diesel is a limited way to reduce petroleum dependance, but the current economics of scale would show the limitations on this (how much frier oil is used vs. the tanker trucks of gasoline per day anywhere? and what price is new veg. oil vs. petroleum? what would the price of used oil go to if demand increases? - Currently bio diesel prices are close to petroleum...that may change if demand or supply curves increase....
