What Has Two Long Ears And Powers Lightbulbs?

Sweden's newest renewable energy source? Adorable little bunnies:

Every year, the city of Stockholm kills off thousands of rabbits in an effort to protect trees and shrubbery in the city’s extensive network of parks and green space. ...

Tuvunger explained that it doesn’t take many newly released rabbits to do what rabbits are known for doing, much to the detriment of Stockholm’s efforts to control the size of its rabbit population. ...

But rather than simply disposing of the dead rabbits, the city instead froze them for eventual transport to a special heating plant in Karlskoga in central Sweden, where the bunny bodies are then burned as a form of bioenergy.

Uh. Well, as long as you're thinning out the rabbit population anyway, may as well recycle, no?

Better than burying them or letting them rot in the parks!

Come to think of it, other than the difference in geographic size, that might be a plan for Australia as well!

More correctly, I'd say they cremate the bodies. Unless these are pretty unusual rabbits, they won't be netting any energy out of the process.

Even if the bodies weren't frozen, burning a body that is 95% water is an endothermic process (my back of envelope calculation, assuming the rabbit is 95% water, 2% anhydrous lipids and 3% anyhdrous protein, gives roughly 400 kjoule per kg of unfrozen rabbit invested in the cremation). Add in the energy used to freeze the corpse, then thaw it, and this is even more clearly a losing proposition.
