A vehicle’s weight is the single biggest driver in its energy use. According to the research non-profit Rocky Mountain Institute (RMI), “In the U.S., oil fuels 94% of our transportation system; cars alone use about 8.8 million barrels of oil at a cost of $2 billion every day.” That’s why RMI is working with researchers and manufacturers on a national effort to transform the automotive supply chain. “Making cars lighter is the single most effective way to dramatically reduce their fuel consumption and accelerate the electrification of their powertrains, weaning autos off oil entirely,” according to RMI.
