The manure from horses in the King's Troop will be used to heat and light the new Ministry of Defence headquarters in London.
The poop from the 170 animals, trainers and horse guard's men of the Royal Horse Artillery will be made into pellets to generate bio-fuel, a Ministry of Defence spokesman said.
At some point during 2011, they will also be doing the same with the waste produced from the MOD staff themselves, as this is thought to be even more efficient than that of bovine or pig excreta.
Some other departments of the government are also considering taking up the initiative although Downing Street has said that they and the house of commons will not be required to take part due to them having been running a similar program almost since its inception, a spokesman for the house of commons said 'we have been full of shit for years'.
