The U.S. Department of Energy Secretary Steven Chu announced today that up to $32 million dollars of Recovery Act funding will be used to expand the harvest of hydroelectric power. “There’s no one solution to the energy crisis, but hydro-power is clearly part of the solution and represents a major opportunity to create more clean energy jobs,” said Secretary Chu.

High-altitude winds hold enough energy to power the world 100 times over.

Though harnessing them is another issue.

You’ve heard of commercial wind turbines in farm fields, offshore turbines on the water, even small wind turbines on the rooftops of homes, but high-altitude winds are also being studied as a potential energy source.

The first-ever study of high-altitude winds by the Carnegie Institution and California State University says winds in the jet stream, about 30,000 feet up, would be the ideal source to exploit. And the sky over New York is a prime spot, along with population centers in the eastern United States and East Asia.

The state of Massachusetts is hunting for unusual places to put wind turbines as it looks to meet an ambitious goal of producing 2,000 megawatts of windpower by 2020.

The Associated Press reports that state officials are encouraging municipal planners to look at using capped landfills as potential wind farm locations. Plans were also just announced for a military reservation on Cape Cod.

The state is hoping to jump start development, because right now, the AP reports, there are only 11 commercial scale turbines in the state. But, ther are dozens of smaller ones installed and nearly 200 other projects in various stages of planning.

In a surprising find, scientists have discovered a microbe that can efficiently convert direct electrical current into methane.

That may be good news for wind and solar power enthusiasts, who have long been faced with the dilemma of how to store energy when the wind isn’t blowing and the sun isn’t shining. This discovery opens the door for generating methane from those renewable power sources; the energy could then be stored as fuel for later use.

But is storing renewable energy in the form of a greenhouse gas like methane a solution, or just another problem?

Right now, there’s no wind in the Great Lakes, but lots of talk.

There’s a bit of money, too, totaling about $100,000 from the federal stimulus package, aka the American Recovery and Reinvestment Act of 2009.

The Great Lakes Commission has been granted $99,740 to develop a set of “Best Practices to Accelerate Wind Power in the Great Lakes and Beyond.”

The end result will be a guide to what works and what doesn’t when it comes to protecting the environment, being sensitive to community concerns and … building wind turbines in the water.

This is the first in a series of environmentally focused cartoons we wil be featuring from Seppo Leinonen a cartoonist from Finland. I met Seppo through Twitter @sepponet and loved his business oriented green cartoons - I think you will too!

Conservatives don’t have a leg to stand on when it comes to protecting our citizens.

A wind farm that was planned for the upstate New York town of Beekmantown and shot down by town officials after a collapse of a turbine at a nearby park, may be back on again.

A new developer has submitted plans to the town, the Plattsburgh Press-Republican reports. The town council voted down a plan submitted by Windhorse Power LLC in March. Among the reasons cited were contentious lawsuits filed by residents, inaction by Windhorse Power and fears of an incident similar to a turbine collapse in neighboring Altona.

Falling into the category of “I guess it’s better than nothing,” the state of Georgia has passed a bill that will use economic stimulus funds to provide retroactive grants to organizations that have already installed clean energy projects.

Passive structure design of “Wind Energizer” by Leviathan Energy reportedly increases wind turbine efficiency 30% in field tests.

Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. Put simply, the model has been: longer blades = more output per turbine.

But that pattern of incremental improvements may be a thing of the past if Leviathan Energy has anything to say about it. Leviathan Energy has completed initial testing on their Wind Energizer unit and is reporting gains in wind turbine output in the ballpark of 30% — and as much as 150% at lower wind speeds.

The principle theory at work is that by placing passive objects around a wind farm it will change the circulation around a large wind turbine. The advancement is not in the turbine itself, but rather in the area around it, as such, units can be adapted to any wind turbine from any manufacturer.

“This is a disruptive technology,” Leviathan Energy CEO Dr. Daniel Farb told me via telephone from Israel last week. “We are changing the environment of the wind turbine; this is a very different approach.”

If you could design the green home of your dreams, what would it look like? What would it be made of? How would it produce and consume energy?
