We see a lot of plans for new green buildings but an existing iconic tower is getting an eco-makeover. The famous Sears tower in Chicago was the world's tallest skyscraper when it was built in 1973. The new plan calls for installing wind turbines and PV to reduce energy use by 10% (the building has already reduced energy consumption by 50%). Adrian Smith of Adrian Smith + Gordon Gill Architecture spoke about the project at this week's Cityscape conference and said it also calls for new lighting systems, extra insulation and a green roof. The Building website has video of Smith talking about the greenification which is expected to cost over $145 million.

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.

It's not quite Brad Pitt body wash but the architecture-loving dad has teamed up with Kiehl's on their new new Aloe Vera Biodegradable Liquid Body Cleanser. The product is the popular skincare brand's first item that is completely eco-friendly right down to the packaging and is certified by Cradle to Cradle. Pitt won't be appearing on the bottle or in the advertising but he did pen a hand-written note that will be on the bottle. All the profits benefit JPF Eco Systems, a charitable foundation created by Kiehl's and Brad to support global environmental initiatives. The project hopes to raise $1 million for charity with the first funds raised earmarked for Pitt's Make It Right foundation, which builds eco-friendly housing for those affected by Hurricane Katrina.

It couldn't be more true that in order to have a healthy world we have to have healthy children, and Healthy Child Healthy World is a non-profit organization that makes that principle their main aim by working to protect our youth from harmful environmental exposures. Working through education, laws, governmental agencies, advocacy, and spreading awareness of environmental issues this charity is a no brainer because not only are they helping kids but they're also helping the environment (something we could all be doing more of).

Fast high-end sports cars are generally not considered to be eco-friendly, with their gas guzzling turbo engines and energy-sucking luxury features. But that's not to say they aren't trying -- Ferrari for example, revealed their F430 Spider Bio Fuel model earlier this week in Detroit. It burns a mix of 85% natural ethanol and 15% gasoline, which results in +10hp (meaning its got a solid 500hp to work with) and a 5% increase in gas mileage over its gas-only counterpart. As for now the F430 Spider Bio Fuel is only a concept, but Ferrari says they'd like to put it into production as part of their efforts to cut emissions by 40% by the year 2012. Like the looks of it?

Damien Hirst, the world's most expensive living artist, is going green in a major way: he recently placed an order for Britain's second largest solar panel system. The system will be used to switch his Gloucestershire country home and studios over to total solar power. I can imagine he's got a lot of electricity needs for his entire estate, but I'm wondering if a 310 watt system (enough power to supply electricity to the equivalent of over 150 homes and will account for 2% of the entire country's solar power) isn't a bit overkill?

Here's a great chance to both do something great for the environment and get something fun to show for it: adopt yourself an olive tree! Nudo, an olive grove in Italy, is offering people the chance to support small scale artisanal farming (instead of the large mechanized operations that damage the earth) by adopting a specific olive tree. And when you adopt an olive tree in the grove for one year not only do you get the satisfaction from the environmental effort, but you also get all the produce from your tree. You'll get a Spring Package with the olive oil from your tree, and then an Autumn Package of more olive oil and some handmade olive oil soap. $130/year.

Even if you're not generally a fan of houseplants, terrariums are a great way to bring some life and green indoors in a way that keeps with structured and styled decor -- you get all the benefits of a houseplant but without the potentially unruly appearance and dead leaves falling all over.

These darling little Esque Terrariums from Velocity are perfect to sit anywhere. Hand-blown, each one is unique and signed by the artist. They're made from 100% recycled glass and heated in a furnace powered completely by wind energy -- truly "green" art in more ways than one! The plant isn't included, and they're available in two sizes (8" and 12"). $600-$800

The principle of a hotel being truly environmentally friendly, especially a nice one, is a concept that is largely debatable. But if you believe in appreciating baby steps, and spend time traveling, this list of the top ten greenest hotels might be of interest.

The encouraging part is that many hotels and resorts are getting away from "token" efforts and going for certifiable measures like recycling and high-efficiency water and lighting systems. Some hotels are better at being green than others, going 100% solar or wind powered, or recycling waste water. But you can do your part, too, no matter where you stay: tell housekeeping you don't need fresh sheets and towels every day, keep your shades drawn to help with temperature control, and don't throw away the left-overs from the mini shampoos and soaps they give you -- take them with you and use them up.

With global warming becoming such an unavoidably huge issue, pretty much everybody has a soft spot for all things "eco." But that being said, not everybody takes it quite as far as Ted Turner's daughter, Laura Turner Seydel, and her husband did when they decided to built the biggest environmentally friendly home in the United States, the EcoManor.

It wasn't cheaper to build, although with features like recycled water from the showers irrigating the drought-resistant lawn, and rainwater-filled toilets, it will be cheaper to maintain -- 80 to 90 percent cheaper than other homes of similar size in the area. And with beautiful white linen wallpaper (made of recycled newspaper, of course) and natural lighting via solar tubes, the Seydels didn't have to sacrifice any style while they were doing their part to help the environment.
