Slight adjustments to the way you shop and cook can result in big savings.

'How inappropriate to call this planet Earth when it is quite clearly Ocean.' –Arthur C. Clarke

The UK government has approved a new scheme for desalination of water from the Thames, for use in London. The £200 million plant will be built in Beckton, east London. It's not a popular plan, though, among environmental campaigners. We've written before

We´ve noted in the past plans for new desalination plants in Australia and low-grade energy desalination technology from New Mexico.

Record droughts, falling water tables and the rapid depletion of aquifers have helped make desalination, a process once considered impractical and too expensive, a viable technology -- at least in some places. As such, there has been a rash of stories --

Directed by David Valero for the Spanish eco-short-films festival La Luciernaga fundida, this video shows how a grandmother and grandson desalinate seawater at home.

This simple, innovative solar still purifies water without electricity or filters.

These low-impact, solar-powered desalination units could be a potential boon to water-scarce coastal communities, disaster-prone areas, as well as local marine life.

Using solar stills to purify water isn't a new idea, but it's an effective one. And now new efforts are underway to use this old technology to help green the desert.

A new desalination technology company is looking to help clean up and recover some of the trillion gallons of salty wastewater from the oil and gas industry.

A new water treatment system could save billions of gallons of water each year by recovering almost all of the waste water at bottling plants and water treatment facilities.

The UAE's clean tech giant plans to have a commerical-scale plant by 2020.

By combining solar PV, solar thermal, and a heat exchanger, Desolenator has developed a low-cost portable water purifier and desalination device powered by renewable energy.

This system could produce 3,500 gallons of clean water per day, at half the cost of current desalination methods, using just the motion of the waves to power the Reverse Osmosis process.

The smart thermostat is now compatible with most home heating and cooling systems in the U.S. and Canada.

A unique solar panel has been designed at Stanford that cools buildings by reflecting sunlight and radiating thermal energy out into space.

The thermostat add-on lets consumers set a limit to what they want to spend on cooling and heating and then it controls the temperature to keep energy use in check.

The technology uses radiative sky cooling to help cool buildings without electricity.

This could keep people from overheating in their wearable electronic outfits or simply in the heat of the ever-warming days

This might be one of the smartest ways to use a smart thermostat.

The company explains why all-electric homes are healthier, safer, and more sustainable.

They're designed as temporary living for Malibu fire victims, but nice enough that they might never leave.

With aging baby boomers and young people who can't afford housing, there's going to be a huge market for these.

Synthetic fertilizer is likely to become significantly more costly for US farmers. This trend will make manure a valuable commodity once again (as it was prior to the 1950s). There are two main reasons for the

A compact chicken coop for city dwellers that wheels around the yard and fertilizes soil is on display at "Dwell on Design" this weekend. The show's awards recognize

Architect and author of Cradle to Cradle talks about green products, his new buildings, and what happened in China.

The omission of ecological services in economics is the equivalent of double bookkeeping: one set that looks (relatively) rosy for us and another for our children.

How about using the light from already existing street lamps to spark off the festive season? Here are some off-the-grid parasite lamps so to speak, that look good by day!

You can't call an aluminum guest house dropped by helicopter green, but you sure can call it cute.

Recycling aluminum uses about 95% less energy than making new one from bauxite ore, which compares very favorably with other types of recycling.

Another reason that we have to use less of the stuff.
