What is the total energy use of all federal buildings in the USA in a
year? Please break this down by source (electric,natural gas heating
oil. This is for buildings where the federal government is the lease
holder and/or owner.

Hello Bill, and thanks for an interesting question.


The US federal government consumed 1.12 quadrillion BTUs (quads) in
2003, the most recent year for which data is available.  Almost
two-thirds of that amount was for vehicle/equipment use (including an
enormous amount of jet fuel use by DOD).

The remainder was chiefly used in federally-owned or federally-managed buildings.


For the category of "standard buildings" -- which is pretty much what
you'd expect them to be -- a total of 0.32 quads (320 billion BTUs)
were used in 2003, as follows:


44.2% -- electricity

35.1% -- natural gas

11.0% -- fuel oil

 3.9% -- coal

 5.8% -- other


An additional 0.08 quads were used in other federal facilities not
included in the category of "standard buildings" such as specialized
laboratories, or manufacturing facilities -- the breakout of energy
sources was similar to the list above.


The total energy costs for standard buildings was $3.71 billion:

70.4% -- electricity

17.2% -- natural gas

 5.4% -- fuel oil

 7.0% -- other


Another $1.04 billion in energy costs were spent at non-standard
facilities, largely for electricity.


The source for these data is the following recent report from the US
Department of Energy:


http://www.eere.energy.gov/femp/pdfs/annrep03.pdf
Annual Report to Congress on Federal Government Energy Management and
Conservation Programs
Fiscal Year 2003
report issued: August 9, 2005



The report is chock-full of specifics on energy use at federal
buildings, and elsewhere in the federal system.

I extracted the information that seemed most relevant to your
question, and I trust this answer fully meets your needs.


However, if there is any other information from the report that you
would like summarized, don't hesitate to ask.  Just post a Request for
Clarification, and I'm at your service.


All the best for the new year,

search strategy -- searched the Energy Department website for [ federal buildings ]

Very quickly done and was what I was looking for but would have been
better if the data was more current.
