The Queen of England is having her two $14 million bespoke Bentley limousines converted to run on biofuels, the London Daily Mail reports.

This is part of a move by the British luxury car-maker to become more environmentally friendly - and a new biofuel-burning high-performance car is expected in the New Year.

In an effort to preserve the Earth, the luxury brand has created a line of eco-friendly handbags named Eco Ferragamo.

What makes this collection special is that the bags are made from a nontoxic tanning technique, are lined in handwoven hemp, and use dyes from natural elements such as tree bark.

The results are luxurious, biodegradable, and water-resistant bags that retail from $1,190 to $1,890.

Looking at these amazing Alila Villas Uluwatu in Bali, Indonesia. Designed by Singapore based WOHA and built on 14.4 hectacres, the Alila Villas are a prime example of amazing sustainable architecture.

With Alila Villas Uluwatu, the architects wanted to create more than the usual stereotypical ideas of Bali, creating a design that worked with the dry Balinese Savannah vegetation and gently sloping site, not against it.

These modern contemporary Balinese villas use sustainable wood for construction (old timbre telegraph poles and wood railway sleepers) to replicate the typical dry Balinese Savannah vegetation.

Notable design features include the flat roofs, laid with batu chandi (local volcanic rock). This porous Javanese rock (a product of Mt Merapi’s eruptions) serves a threefold purpose: insulation; as a means of blending in with the local landscape; and for water absorption to support plant life.

Even the jigsaw-like exteriors of the pavilion serve more than an aesthetic purpose. The slats of these exteriors are made from a mixture of recycled wood and bronze, allowing for breeze to circulate yet maintaining privacy in partially shielding its occupants away from prying eyes.

The villas are perched on limestone cliffs with a stunning view over the Indian Ocean, large windows that extend into the natural open spaces. This green resort opens its doors to the public in 2009. Via Contemporist

Private yachts are somewhat synonymous to luxury, but does that ever mean that they cannot get ecofriendly? No is the answer from Island Pilot LLC, who have unveiled the first ever hybrid luxury yacht dubbed the Island Pilot DSe Hybrid 12m, powered by diesel fuel, solar energy, and electric power.

The vessel is 12 meters long (39.5 feet) and can cruise at 13 knots on diesel fuel and 7 knots when in zero-emissions mode. A zero-emissions level is achieved with a 6 kW solar array and a 20 kWh battery bank.

The yacht is the first-ever production motor yacht with zero emissions in America, according to Reuben Trane, president of Island Pilot, LLC.

The entrants for the 2008 Design Los Angeles Challenge have been officially released, with the Mercedes-Benz Advanced Design Center of North America unveiling the creature pictured before you – a model they’re calling the Formula Zero. Built around the theme of motor sports racing in the year 2025, the Formula Zero concept aims to combine “the thrill of Formula One, the track dynamics of the bobsled or luge, and the grace and efficiency of yacht racing.”

Reminiscent of the Mercedes Benz racing heritage of the 1930’s, the Mercedes Formula Zero Racer concept is loaded with technology designed to extract the maximum thrust from the electric hub motors, aero-efficient solar skin and high-tech rigid sail.

Unlike traditional racing, where the racers aim to finish first, this new concept introduces energy efficiency as the most important part of the competition. Here all the racers are allotted the same amount of energy, and it all depends on the design of the car and the skills of the racer from there onwards. The more the energy efficiency of the car, the better are the chances to win. The winners are finally determined by the time taken to complete the race and the amount of energy used in doing so.
The Mercedes Benz Formula Zero racing Series will be held on a transparent track, which will be visible to the spectators from all angles.

If you’re an environment friendly sailor and have a passion for speedboats check out Czeers MK1, a luxury designed 10-meter that was launched at the Millionaire Fair in 2007.

The Delft Technical University Solarboat Team built the original platform as an entry in the 2006 Nuon Frisian Solar challenge, which it easily won - and in the process, attracted serious investment power from Rabobank to get a full scale test boat built.

Made 100-percent of carbon fiber with orange leather trim, photovoltaic cells on almost all horizontal surfaces and an LCD touch-screen control system, the world’s first solar speedboat goes up to 30 knots on water.
