When did water fountains become more of a novelty than an expectation in urban areas? And when did their restoration become news? It seems to say something about the state of free clean drinking water in cities - perhaps we've realized we've gone too far towards bottled water and are finally, finally making our way back to the tap. Either way, London has restored a drinking fountain in famous Trafalgar Square, and hopes that it starts a trend of renovating fountains across the city, returning free clean water to citizens who are out and about enjoying their public spaces.

In Lima, Peru, more than 1.3 million people have no access to drinking water. The citizens without it are in the poorest areas, where water trucked in can cost nine times as much as it does in richer areas. So, citizens have had to either make do without running water, or, with the help of a German NGO, make dew into drinking water.

Peepoo Bags Promise to Clean Up a Lot of Global Crap

Sometimes we get so concentrated on the small (yet important) details of green we forget about the big picture. Or the news seems like nothing but bad. But there's good news, too. To combat the problem of lack of sanitation and clean water -- 2.6 billion people don't have access to toilet facilities -- the smart folks at Pee Poople will soon start distributing in Kenya and Bangladesh a "biodegradable" bag called Peepoo that has an inner lining that disinfects the poo so that bag can be help fertilize soil instead of polluting precious water supplies.

Coal Country: Enter to Win the Book, Sign Up to See a Sneak Preview

My hope is this superb documentary will shock Americans and create a surge of
urgency that stops the atrocity of mountain top removal coal mining immediately.

-- Ashley Judd

Coal Country_bookcover.jpgI know it doesn't work as literally as this, but what would you do if you knew that ancient mountains were being destroyed and communities torn apart every time you turned on a light in your home, or flipped the switch on your sound system, or heated up water for tea?

There are a few more steps in the mining-to-lightswitch process, of course, but this is basically the story of mountaintop-removal mining. I want to invite you to attend a sneak-peek screening of a stunning new film on the subject, called Coal Country , and also to sign up to win one of ten free copies of the film's companion book, Coal Country: Rising Up Against Mountaintop Removal , published by Sierra Club Books.

How the Bushmen of Africa Can Save Us from the Global Water Crisis (Video)

I started in on a book about a month ago titled Heart of Dryness, which discusses how the bushmen of the Kalahari can teach us what we need to know about how to live in dry climates, something we're all increasingly finding ourselves in as we drill ourselves further into a global water crisis. However, due to political turmoil, the bushmen - the very people with all the knowledge and tools that can help billions of people cope with a growing lack of water - are a culture of people vanishing from the face of the planet. While frightening, it's a fascinating read, so I was excited to see a video interview with the book's author, James G. Workman, who discusses more about the book, the water crisis, and the quiet knowledge of the bushmen. Check out the short interview after the jump

Ask Pablo: Refrigerator Water Dispenser or Refrigerated Bottles?

Dear Pablo: We drink a great deal of water all day long and wondered which uses more energy: opening the refrigerator door to get a bottle of cold water or using the water dispenser on the exterior of the unit. Also, does it take more energy to get ice from the mechanical dispenser (which also uses energy to make ice) or more by opening and closing the freezer door to get some cubes?

The big picture answer is that it probably doesn't matter. Simply the fact that you are filling your own water bottles rather than buying bottled water is a much more important environmentally-friendly act. Both your refillable bottle and water that is dispensed by your refrigerator are taken from the same starting temperature to the same final temperature, so there is no difference there. Where there is a difference, however, is in the act of opening the refrigerator door and allowing all of that cold air to spill out (hot air rises, cold air falls). By using the door-mounted dispenser this loss of cold air is avoided.

You don't need electricity to do the laundry. It's as easy as riding a bike.

My wife's 90-year-old aunt still washes her laundry by hand, and dries it with a wringer.

God bless her. But if you're a little busier, you can keep your clothes clean with pedal power. GreenovationTV has a segment on the low-tech solution.

Smart Water Technologies To Be a $16.3B Industry by 2020

Electricity gets all the attention when it comes to the smart grid, but not to be ignored is also what a smart grid can do for water consumption. Americans consume twice the world average in water, massive amounts are wasted in households, manufacturing, agriculture, and landscaping - massive amounts that could be conserved through proper monitoring and accounting. Luckily, water footprints are getting increased attention, and a water grid is being zeroed in on by businesses such as IBM who is working on boosting technology behind everything from high tech water pollution sensing to water footprint accounting. . In fact, the water grid could be the next big business concept, set to be a $16.3 billion dollar industry in the next 10 years.
