green fuels

Prince Charles is not new to the environmental debate. His blue, 38-year-old Aston Martin, however, has had nothing to do with being environmentally friendly. Until now. The car, a gift from the Queen on Charles' 21st birthday, has joined the growing fleet of cars that run on bioethanol, having been converted to run on surplus British wine.

The wine comes from an English vineyard in Wiltshire, and the EU limits how much wine a vineyard can produce, so the vineyard sells the overage to Green Fuels, which turns it into biofuels and supplies it to the Palace.
