This sounds environmentally friendly: Powering whaling ships on whale oil

An appalling article in the Guardian:

It is a fantastically surreal propostion. An Icelandic whaler, Kristján Loftsson, is powering his whaling ships using "biofuel" composed of 80% diesel – and 20% whale oil. Loftsson claims the oil is additionally friendly to the environment as it is rendered out of whale blubber using heat from Iceland's volcanic vents.

It's almost as bad as this:

It's not the first time animal fat has been used to feed the whale hunt: 20th-century whaling operations in the Southern Ocean made similar use of penguins, throwing the oil-rich animals on fires as living kindling.

Yikes. More in the Guardian.
