Nice spread Barack and Michelle have there, eh? From Eric Peters at ericpeters.com:
Like propane.
An ocean of it, in this case. So that the Obamas have plenty of fuel – as opposed to solar – to assure the power never goes off at their place. Which is actually a $12 million-dollar, 6,892 square foot mansion more than twice the size of the average American single family home – with more than twice the “carbon footprint,” too. 
It is the real-estate equivalent of the gas-hoggiest non-electric car you could possibly buy – but which we increasingly cannot afford to drive, courtesy of the artificially induced energy austerity imposed on us by things such as Obama and his anointed successor, the Biden Thing.
