The amount of energy used by the US Government was at its lowest level in nearly three decades in 2013, latest statistics reveal.
According to the US Energy Information Administration (EIA), total energy use “delivered-to-site” fell to 0.96 quadrillion British thermal unit (Btu) in the 2013 financial year (FY) – the lowest recorded since 1975.
Vehicles and equipment energy consumption accounted for 62% of all federal energy use in FY 2013, with the rest of it consumed by federal facilities.
The US Department of Defense and the Postal Service together accounted for 94% of vehicles and equipment energy consumption, a 19% fall from 2011 to 2013.
The EIA said much of the decline could be due to lower usage of jet fuel, a major fuel source for the US Air Force and the largest energy source for the government.
Energy costs for the government have been rising since 2000 – from $9.4 billion to $24 billion in 2013.
