The unicorn of cheap clean home energy will most likely be found in an affordable solar roof that doesn't look like a solar roof, and that can pay for itself quickly. This startup may have developed it.

The unique paint could provide clean power to homes at a low cost.

This digitally knitted canopy uses photo-luminescent yarns to create a semi-shaded summer pavilion for visitors to NYC's MoMA PS1 gallery.

So far the panels and batteries are only offered in the UK but it might spread to sunnier North American climes.

A new study says yes, but luckily the fix is simple.

The project will also include molten salt energy storage for 24 hour solar power.

The blocks could be part of the architecture of a building, generating more power than just rooftop panels.

The solar cell can be stretched, bent and compressed without substantially affecting performance.

The HELIOtube is a radical departure from conventional CSP technology, as it is based around tubes of inflatable plastic film.

Tesla's tiny house integrates solar power and its Powerwall home battery into a seamless system, and can be towed by the Model X.

While the world chases solar generating windows, we see how to do solar generating walls.

A new breed of solar panel can do double duty on greenhouse roofs by not only generating renewable electricity, but also by using a light-altering dye to help optimize photosynthesis in the plants beneath them.

When printed in a precise pattern onto carbon nanotubes on paper, these photosynthetic bacteria can produce electricity from sunlight, which could power biodegradable environmental and medical sensors.

The technology makes for better energy generation and a better window.

Is this totally silly and a waste of time and money, or is it a great leap forward? Or is it too soon to tell?

It also comes with its own beer dispenser, built-in right in the couch.

This home for a family of three and two cats has been built with efficiency, comfort and health in mind.

Tens of millions of sharks are mutilated and left to die slowly each year so that some affluent people in Asia can each soup. This has to stop.

One design attempts to deal with the problem of plastic bottle caps -- which often get discarded rather than recycled.

It would be a good way to further broaden the appeal of electric vehicles.

The dead ones washing up on beaches are "just the tip of the iceberg."

Our photo of the day comes from the waters off Sydney, Australia.

In honor of St. Patrick's Day, we decided to take a look at creatures just as elusive as that pot of gold. The lush green landscapes of the Emerald Isle look calm and peaceful from far away -- but Ireland's species -- from a gorgeous barn owl to a toad

The largest honey packer in the US faces criminal charges over fraudulent trade in Chinese honey.

Now that the Toyota International Teacher Program has ended, I've decided to turn the spotlight on a few of the teachers involved. First came the middle school teachers. Next up, a couple of the high school-teaching

Sylvia Earle won the 2009 TED prize for her presentation on oceans, and this year got her Mission Blue project up and rolling to create marine preserves. Earle's wish was that we all use all the means at our disposal to tell the story of oceans in

Darwin made a smart choice when he picked Galapagos as the place to develop his theory of natural selection: This group of islands has some of the most incredible species in the world. Earlier this month, a star-studded group of adventurers with the Missi

A star-studded group of adventurers with the Mission Blue oceans conservation group went on a trip to the Galapagos earlier this month. But the true stars of the show were the incredible species endemic to the islands: many

Yesterday Brian wrote Galapagos Islands Moved Off Endangered Sites List, concluding:

Lonesome George is quite a character. He's a Pinta Island tortoise, and, as Brian noted when he visited a few years ago, he's the last of this breed. Yep, that means when he's gone, that's it -- his species will

The ballooning rates of people coming to the Galapagos, as residents or tourists, over the past few years has created a variety of environmental concerns for the islands. Not least of these is waste management, as the

When it comes to the Galapagos, most people think: Islands; tropical; Equator; volcanoes; some variation on those general ideas probably pops to mind, unless you've been here. If you have been here, you probably know that a

Each of the islands in the Galapagos is incredibly different. From landscape to ecosystem to the endemic species that can only be found in that

The Galapagos Islands are the model of biodiversity which inspired Charles Darwin to surmise the theory of evolution, but scientists have made arrangements to ensure that the latest round of animal deaths

Lonesome George, the world's last remaining Pinta Island tortoise, has died at age 100 -- marking the final end of a species millennia in the making, and inching that 'loneliest' mantle one notch closer to us.
