A new technology can speed the purification of water using sunlight, potentially providing clean water to billions of people.
The forward momentum on recycling has stalled in the U.S. and other countries, but some experts say there's still potential for growth.
Cockroaches are taking a big bite out of a Chinese city's trash problem.
Urine is so much more valuable than we think. Soon, we might be building houses with pee bricks.
While green roofs make sense in a lot of ways, requiring their installation isn't as simple as it might seem.
While plastic such as Styrofoam may be cheap and convenient to use, it contributes to costly health issues and is an inconvenient pollutant that takes up to 500 years to biodegrade.
Fog harvesting has been going on in some form since ancient times, but scientists have been refining the method so people living in some of the most arid climates can have water.
And they're ready to help you do it, whether it's just you, your school, your company or your neighborhood.
Drones and other unmanned flying machines are going green.
We live in an age when DIY has taken on exciting, nerve-wracking connotations. Add in some knowledge and some money from crowdfunding sites like Kickstarter, and you have a recipe for a transformed world. Will glow-in-the-dark plants be a part of it?
As far back as 1500 B.C.E., people were trying to purify water to make it drinkable. And we're still at it. Today inventors use tools as simple as clay and as sophisticated as carbon nanotubes to bring clean water to the world.
While you shouldn't expect to find a "flying electric" option at the airport anytime soon, electrically powered aircraft not only exist, but the technology continues to evolve at an encouraging rate.
Solar energy is abundant and infinitely renewable. Therefore, it's not surprising to see the proliferation of devices that rely on the sun -- especially solar aircraft.
If you live in the right spot -- somewhere that's sunny most of the year with low humidity -- you can save a lot through solar power. So which five cities are the best?
So a space shuttle launch may not be the most environmentally friendly thing in the world, but there's more to NASA than space travel. What are five of the most important ways NASA helps the environment?
The Northeast Blackout of 2003 left millions without power and cost approximately $6 billion. Experts believe we can avoid future blackouts by storing energy along the U.S. electric grid.
We're still a long way from a supposedly paperless age, but companies have come up with some ideas on how to squeeze more from a tree. How does high-yield paper rate among the spectrum of green products available?
Why would Los Angeles and Pittsburgh set out to convert a combined 180,000 traditional high-pressure sodium and mercury-vapor street lamps to LED lighting?
Children love to play, so why not harness the energy of their motion to help support a community. How does the PlayPump convert the push of a merry-go-round into clean water?
Sometimes you need to reinforce roads or retain walls without breaking out the concrete and rebar. That's where a simple, ingenious technology comes in.
Photovoltaic solar panels are like windows -- they build up a coating of grime that requires a good cleaning from time to time. What's the alternative to climbing the roof with a squeegee and bucket of suds?
Without a doubt, plastic is useful. It's also everywhere — filling up landfills and recycling bins. These 10 twists on the common polymer are trying to change that reality.
Some of the newest ideas in technology come from very old ideas -- they're inspired by nature. How do the plants and animals around us give engineers ideas?
Eco-plastic seems like an oxymoron, and it very well may be. What exactly is eco-plastic, and does it really help the environment?
You probably ignore most billboards, especially those annoying ones that read, "If you lived here, you could be home by now!" But what if that giant ad you drove past were alive?
