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

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

On Monday, a molasses pipeline (yes, that's a thing!) leaked 1,400 tons -- 233,000 gallons -- of molasses into Hawaii's Honolulu Harbor and it has turned into a killer mess with no quick solution.

It's not quite as dramatic as it sounds. It's simply a good demonstration of the power of regenerative braking!

There’s some good news about the endangered Hawaiian monk seal.

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

It's the first plant plant of its kind in the states that generates electricity from the temperature differences in the ocean.

This short film, while focused on the island of Kauai, highlights the challenges and crises we will all have to face on our island planet.

Solar City and Tesla take the Kinks out of solar power with plenty of PowerPacks

Nuclear power generation in the United States is falling. It plateaued between 2007 and 2010—before falling more than 4 percent over the last two years. Projections for 2013 show a further 1 percent drop.

On Monday (Sunday locally), Japan switched off the last of its operating nuclear reactors and became 100% nuclear-free.

Most of us alive today owe a debt to those who avoided nuclear war in years past, and sadly, there were many occasions when that was necessary.

Tons of jellyfish clog a water intake pipe at the Oskarshamn power plant in Sweden, forcing operators to shut down the reactor.

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.

MIT design cuts fusion reactor down to a size that would be more cost effective and could be built in five years

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

Can a rare metal travel without a passport?

Instead of building giant concrete buildings filled with uranium, why not build smaller energy-efficient buildings filled with people.

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 slice and dice some recent posts on technology

A roundup of some posts from our sister site.

Why are our cities being designed around the needs of the trucks instead of vice versa?

And dancing robots!

Why does this not surprise me?

Greenpeace's annual survey of national retailers' progress on sustainable seafood reveals the leaders and the losers.

Scientists hope the technology that filmed it can make fishing more sustainable.

Nestle and Tesco are the latest members of a worldwide movement against abandoned fishing nets.

A new study used DNA testing to reveal shark meat being sold under generic fish names.

It takes the controversial stance that more fish doesn't necessarily mean better fish.

If it weren't for an added colorant, it would be grey or white like most of the other fish on display at the store.

George Monbiot, everyone's favourite controversial climate commentator, launched the Be The Change conference with a bang here in London yesterday. He leaped off the starting blocks with the statement that not only is it imperative that we reduce Co2

In his erudite analysis of the global warming issue, Don Blankenship of Massey Coal expressed his opinion about the future of polar bears:

The debate over the true ecological sustainability of biofuels, the effects on global food prices, and their oft-heard claims of carbon-neutrality has been played out on TreeHugger in great detail. Adding a new

The Guardian's George Monbiot talks about climate deniers, junk science, and the need for nuclear.

Actually, we have been down this road before...

No they don't. Whether or not you buy into this study, the fact remains that cars are cars are cars.

"Let’s abandon this disastrous experiment."

I get the design part, but is it really sustainable?

These spikes might be intermittent. But they are getting bigger and more frequent.

Fortunately, that's not the only change in their building regulations.

Even with falling subsidies, solar still makes sense.
