London's Science Museum is reportedly considering methods to cut their utility bill by burning human waste or using it to feed microbial fuel cells. Management predicts that visitors' crap could generate 1,530 kilowatt hours of electricity per year.

"As with all energy sources, you have to make the most of what is available and we certainly have an abundance of visitors - and almost all of them use our toilets," museum head Jon Tucker told the BBC.
