A community soccer field in Rio de Janeiro stays well lit at night thanks to energy harvesting tiles laid under the turf.

This quick project makes a useful emergency flashlight while recycling your leftover cardboard.

Walking and other gentle movements could power the next generation of devices.

The city council has begun installing solar-powered lights around the streets of downtown Nairobi.

An international music festival in the slums of Nairobi is unusual enough. But one that plans to stop a dam and save an indigenous way of life? Let's party.

It's not an 8,000 mile journey across the Pacific Ocean, but it's still pretty cool.

A public memorial ceremony will be held in NYC for Wangari Maathai on November 14.

From record investments in energy investments made by US states, to East Africa's largest wind power project, Chicago's smart gridization, to Chevron's huge fine being upheld, here's what we're reading today.

A UK offset company launches a world-first partnership to finance Life-Straw water purifiers in Africa.

Jason Aramburu is trying to revolutionize how we garden by expanding the production of "Black Revolution" biochar, a soil-less growing medium made from farm waste.

Now in its sixth day, the forest fire threatens critical habitats and precious water sources.

The estimated 80% of Kenyans that are not on a grid rely solely on kerosene to light their homes. But a pay-as-you-go home solar system promises to deliver clean, affordable lighting to rural areas.

There's been much talk of Africa "leapfrogging" the paradigm of fossil fuel dependence. Kenya's latest announcement on solar power provides a vision of what that might look like.

This photograph was taken at Nairobi National Park, which is located just four miles south of the city’s urban center.

This waste-to-resource project not only produces a less smoky and long-burning fire, but could also help improve health and sanitation outcomes.

No more plastic bags means a return to old-fashioned ways of packaging and carrying goods -- not necessarily a bad thing!

It was shot from "sea to summit" in Hawaii Volcanoes National Park, one of the most dynamic landscapes on Earth.

Last week, 233,000 gallons of molasses spilled into Hawaii's Honolulu Harbor killing thousands of fish, eels, crabs and other aquatic life. And the damage continues to worsen.

Building her first tiny home meant enough financial freedom for this tiny house builder -- enough to build another off-grid tiny vacation home in Hawaii.

Decommissioned buses are getting a second useful life as mobile shelters for Honolulu's homeless.

On the first of this month, Hawaii became the first state in the U.S. to put a plastic bag ban into effect.

There are worse places to be stuck than in Hawaii... I'm starting to think they did it on purpose!

Move over, indoor birthing tub. This woman wants to deliver in the Pacific Ocean with dolphins as midwives.

The new species endemic to the marine protected area expanded by Obama was named in honor of his efforts to protect and preserve the natural environment.

When sunscreen chemicals wash off beach-goers, they bleach coral, stunt its growth, and sometimes kill it outright.

More pedestrians are getting killed in the roads. Are their phones really the reason?

Simple, no frills cabin living at its best, right by the ocean.

Many sunscreens contain chemicals that are devastating to sensitive coral and other marine life.

In China, wind power is leaving nuclear behind. Electricity output from China’s wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled away—outdoing nuclear by 22 percent.

Nuclear power is so controversial; an engineer working on the Bruce Nuclear plant gives his point of view.

We still need a ton more renewable energy in order to combat climate change, but the good news is that renewable energy is picking up the pace.

The number of wolves alone around Chernobyl is more than 7 times greater than can be found in other nature reserves.

Mushrooms and game meat in European regions where Chernobyl fallout was most intense still have excess radiation, but Burgundy truffles get the green light; foodies rejoice.

It's a job even too tough for robots.

Earlier research found evidence of a wildlife wonderland at the disaster site, now the first camera study validates an abundance of wolves, boars, foxes and more.

The technology turns the problem of nuclear waste into a source of safe nuclear energy.

There is so much in their new strategy that I can't get it all in the title.

This is, in fact, one of the things that e-bikes are really good at. Another dumb move.

Eben Weiss, the Bike Snob, is an unexpected source for this proposal to save the environment.

I'm not quite sure, and the more I look, the more confused I get.
