Energy Consumption by Road Transportation in the United States, 1970-2012 (in Trillion BTUs)
In terms of energy consumption by the road sector an important trend concerns the decline of the share attributed to the automobile and other light duty vehicles. This is attributed to better fuel economy, but the most significant explanation relates to a shift in consumers preferences towards sports utility vehicles and other light trucks. This type of vehicle accounted for almost as much energy consumption than the automobile, while essentially servicing the same type of mobility demand. However, since 2010 this share declined in part because of higher petroleum prices. Improvements in fuel economy and lower levels of economic growth are the main factors behind the decline of the energy consumption by the road transport sector after 2005.
