Our energy and mobility systems are designed for the era of $10-a-barrel oil, an era that is long gone, and not coming back. Without planning ahead to a future where fossil fuels are not our primary source of energy, our region will remain dependent on a diminishing, increasingly expensive resource with well-documented impacts on both the environment and the world’s geopolitical stability. Moving away from oil dependence and meeting our greenhouse gas emission goals will mean building more energy-efficient communities. This in turn will affect everything from the design of our transportation systems to the design of our streets.
