A group calling itself the International Climate Science Coalition (ICSC) chose today, Earth Day, to rain on the climate change parade.

The ICSC cannily chose the day to release the names of 500 “climate realists” who endorsed its Manhattan Declaration on Climate Change, which calls on world leaders to “reject the views expressed by the United Nations Intergovernmental Panel on Climate Change (IPCC)” and Al Gore’s popular movie, An Inconvenient Truth.”

It's no longer news that rising commodity costs (such as oil) have been making alternative commodity sources (say, like tar sands) increasingly cost-effective.

But it is news when the reverse happens.

A paper mill in the central Canadian province of Manitoba is no longer accepting paper for recycling because the price of newsprint has dropped so low that it's no longer cost effective to recycle.

Instead, the mill plans to simply cut down trees to make its paper.

IBM has introduced a 3D online multiplayer game to help teach kids about renewable energy.

Intended for use in and out of classrooms, PowerUp challenges teenagers to help save the planet "Helios" from ecological disaster.

Don't have a market for your technology? Make one. Then franchise.

That's what tiny Xynergy (PINKSHEETS: XYNG) of Carson City, Nevada is planning to do for its hydrogen generator, details of which are vague, but which it touts as "the only one in the world that can turn hydrogen into real power in a cost efficient manner."

The company plans to open a restaurant this summer in Boulder, Colorado using its hydrogen generator as its primary power source. The restaurant is also to feature "revolutionary" refrigeration systems currently in prototype form developed by Xynergy.

Solar industry and media types gathered in the desert of Nevada today... but it wasn't for Burning Man this time.

No, today marked the formal commissioning of a 14 megawatt solar photovoltaic system at Nellis Air Force Base outside of Las Vegas, touted as North America’s largest solar photovoltaic installation (see Biggest U.S. solar PV install underway at Air Force base).

With a name like Green Alternative Motorsports, you were expecting a blue car?

What do new strategic messages from solar manufacturer SunPower (NASDAQ: SPWR) suggest about its future direction?

For those who wonder what CO2-to-algae looks like close up, there was a demonstration system at this week's Burning Man festival.

New uses for old colostomy bags?

It's the end of an era.

We hope we look this good when we're 84.

Tech giant Google—wealthy enough to have resources to pursue environmental leadership in whatever obscure place it may—has taken an odd step.

It has introduced a black background version of its search engine.

Yes, it's the same old Google. Just on black, instead of white.

Why?
