Uncharted Waters

read
In the chaotic aftermath of the Gulf oil disaster, one thing is clear: we need to start tapping the clean energy potential of our oceans.

At present, upwards of 200,000 gallons of oil are pouring into the Gulf of Mexico daily. President Obama is rushing to assign responsibility, which BP CEO Tony Hayward readily accepted before shifting the blame to the drilling contractor. The left-wing is trying to contain damage to the environment as the right-wing does the same with its political agenda. But, for all the commotion, precious few......read more

Rising Tide

read
World's largest tidal power turbine unveiled in Scotland.

As a potential clean energy source, tidal power is as alluring as it is elusive. The consistent daily flux of the tides presents attractive possibilities for the production of reliable, sustainable power, but the hurdles posed by deploying large turbines in the sea are more than a little significant. Still, tidal energy projects, particularly in Europe, are attracting plenty of capital......read more

Tidal Power Starts Flowing To The Grid

Let American offshore power begin

It's official: America's first offshore turbine is feeding the grid. No, it's not a wind turbine, but it's no less notable. Less than a month after the feds approved America's first commercial wave power project, Forbes reports that Ocean Renewable Power Company's TidGen device has started providing power to a utility grid in Maine. The TidGen turbine sits in......read more

Underwater Kites Harvest Energy From Tidal Currents

Minesto's 'Deep Green' tech starts producing electricity

A kite-like tidal power device off the coast of Northern Ireland has begun producing electricity. The technology, called Deep Green, consists of a hydrodynamic wing and a turbine tethered to the ocean floor. The tether also contains the unit's power and communication cables. As water flows over the wing, the turbine rotates and generates electricity. In an offshore control room, located in the......read more

Mobile Solar Power

read
Gigantic articfical waterfall design unveiled for Rio.

If only these were around when I was working as a laborer, inhaling gas fumes and slowly going deaf by the roar of the power generator. Unlike internal combustion generators, Mobile Solar Power's transportable solar generators create zero emissions, zero exhaust and zero noise. There may be a few zeroes on the price tag as well, but with only a few moving parts and no need for oil or......read more

Phasing out Coal in Canada

read
Country moves to make natural-gas fired plants the new clean-power standard.

The Canadian Minister of the Environment has announced that coal burning power plants must drastically cut emissions or face closure by 2025. The pronouncement signals a national shift towards more efficient, less polluting natural gas plants. The measure is expected to reduce Canadian emissions by approximately 15 megatonnes, which equates to taking 3.2 million vehicles off the road. The exact......read more

Obama Announces Solar Power Support

watch
The President declares federal loan guarantees for solar energy projects.

Good news for clean energy advocates, as Obama used his Saturday address to announce almost $2 billion in conditional loan guarantees to two solar energy companies. The beneficiaries are Abengoa Solar, whose planned Arizona solar plant will be one of the largest in the world, and solar panel manufacturer Abound Solar, which will build advanced panels at two new plants in Colorado and Indiana. Not......read more

Tower of Power

read
Is concentrated solar power the future of renewable energy? A Guardian video shines a light on the world's first commercial solar tower.

For most of us, the vision of a solar-powered future conjures a mental image of rooftops covered in photovoltaic panels. But PV tech is actually only a few decades old, and humans have been harnessing the sun's power for millenia. Concentrated solar power (CSP), or "solar thermal," is an ancient, low-tech version of solar energy capture, in which the sun's heat energy is used to boil water and......read more

Greenland's shrinking, Brooklyn's getting bike sharing, Rush Limbaugh is still an asshole, and more.

Plant Plastic: Drinking soda is bad for you, yes, but petroleum-based plastic bottles bad for everyone. In 2012, Pepsi will drop the world's first fossil fuel-free plastic bottle, made from 100% plant-based materials like switch grass, pine bark and corn husks. Bike Share, Yo: Inhabitat reports that Brooklyn will join Washington D.C., Boston, Denver, and Minneapolis as the first cities in the......read more

Creating Energy from Water

read
Tata and MIT join forces on revolutionary new energy tech.

Indian corporate giant The Tata Group and MIT are collaborating on new research that produces energy from water. The technology, developed by MIT scientist and SunCatalytix founder Daniel Nocera, is founded on a basic scientific priniciple: sunlight + water = fuel. Nocera's process essentially mimics photosynthesis by using sunlight to split hydrogen from water. It is said that it can generate......read more
