The Gulf oil spill is the latest in a series of warnings that we must reduce our dependency on petroleum with an eye toward moving away from oil entirely. While "getting off oil" remains a distant goal, we can choose to halt oil expansion today. Technologies exist to improve the efficacy of biofuels and to stretch the availability of existing petroleum supplies through increased efficiency. Rather than choosing more offshore drilling, we can choose demand-side innovation to meet our current energy needs without the risks associated with further oil expansion.
