The British Queen Elizabeth II has two state Bentleys, which according to the US Department of Energy gets nine MPG in the city and uses 31.1 barrels of petroleum a year. These royal $15 million gas guzzlers are being converted to bio-ethanol.

According to Jalopnik, the Queen is preempting Bentley’s move to biofuels:

Queen Elizabeth the II, who lives rent free in several state-owned mansions and castles — the poorly insulated kind that are a bitch to heat in the winter — travels by a state-owned private jet and requires a security detail that uses many fossil fuel powered cars, trucks, motorcycles and helicopters, has decided to do her bit for the environment. The biofuel conversion is estimated to increase the fuel economy of her two, scarcely used, Bentleys by a staggering 40%. How?
