Prince Charles has long been known for his eco-efforts including driving a wine powered car.
But Queen Elizabeth is green-minded too. The Daily Telegraph reports that
Queen Elizabeth who has also set up an energy-saving committee at Buckingham Palace, is turning Balmoral, her Scottish estate, into a property that is completely energy self-sufficient. A small hydro-electric plant has been installed at at Balmoral and it sells electricity to the national grid. The plant was developed on the Gelder Burn, a stream in the estate forest and generates enough power for Balmoral and for 1,000 private homes in the area. A water-driven turbine was originally installed in the 1920s to provide electricity, in the 1950s it was used to power the estate sawmill, and now since the mill is no longer in use a generator was installed which allows the turbine to be connected to the National Grid and offer power to the surrounding homes.
The Balmoral woodlands are registered with the Forestry Stewardship Council which supports sustainable forestry worldwide and all farming practices are registered with the Soil Association, which promotes organic food and farming. The estate is also a big recycler turning tons of organic waste into compost each year. Even the royal protection officers pedal around the estate on bicycles and use their vehicles less. It's all part of the Queen's commitment to climate change initiatives, a stance which she has urged other nations to adopt.
