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.

Looking like a "great ship," this solar-powered music venue is a new gateway into the city.

Campbell Soup Company will soon be sourcing about 15 percent of the energy used at its factory in Napoleon, Ohio (the company's largest) from solar power generated by a just-announced power purchase agreement (PPA) and land lease

With research showing the installed cost of solar dropping 11% in just 6 months, it's little wonder that corporations like Wal-Mart are ramping up their plans to go solar aggressively. Walgreens made headline back in 2006 for its commitment to solar,

Peru continues to approve oil and gas projects despite previous exploration leading to the death of half the Nahua tribe.

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

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.

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.

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.

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

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

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

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.

I am sorry, they are a dumb idea, and the data prove it.

Instead of an exciting adventure, we got a road not taken.

He says it is all part of the grand plan and we shouldn't worry.

The technology could lead to cheaper hydrogen cars in the future.

It wasn't too long ago that biofuels were basking in the glow of nearly everyone's approval - a quick fix for reducing CO2 emissions from transport. The EU aims to fill 10% of its transport needs with biofuels by 2020. But biofuel's easy ride may be

Instead of turning sunlight into electricity, and then using that to power indoor lighting, Lucy redirects the daylight into rooms for effective natural illumination.

This solar + battery + LED light combo aims to be the future of portable light & power.
