If the U.S. moved aggressively to start harnessing the solar power it receives daily, it could generate enough clean energy to meet the country’s needs many times over, according to a new report from Environment Florida.

The report, “On the Rise; Solar Thermal Power and the Fight Against Global Warming,” touts the multiple benefits of solar thermal power that the U.S. has barely begun to tap. One, it’s a clean source of energy that could replace other power sources that generate greenhouse gases and worsen climate change. Two, by storing thermal energy, it can generate electricity even when the sun isn’t shining. And ,three, it’s wildly abundant in the U.S., offering way more clean energy than we currently use on a daily basis.

Denmark-based Vestas Wind Systems (VWS:DC) had a big week. First, the world’s largest wind turbine manufacturer announced that they would be building a tower manufacturing plant in Colorado. Second, Vestas reported a 94 percent jump in earnings in the first quarter of 2008, as compared to the same period last year.

Although they have yet to disclose the location of the new tower manufacturing facility, it would be situated to complement the company’s fist North American blade manufacturing plant, which recently opened its doors in Windsor, Colorado.

For the tower plant, the company will need a large parcel of land served by freight rail, a combination that Northern Colorado can provide at several locations, including the Windsor location, where construction proceeds on phase two of the blade plant. According to the Northern Colorado Business Review, more than 1,000 new jobs could result from further expansion of Vestas’ manufacturing presence.

In 2005, Governor Schwarzenegger signed into law Executive Order S-3-05 which sets a long term greenhouse gas emission reduction target of 80% below 1990 levels by 2050. Reaching this ambitious target will require that California embark on a comprehensive strategy to make aggressive reductions in greenhouse gas emissions over the next four decades.

Nationwide, electricity generation is is the second largest contributor to greenhouse gases. It is incomprehensible how the 80% greenhouse gas reduction target could be reached without tremendous amounts of renewable energy and energy efficiency. I am not saying that greenhouse gas reductions and renewable energy are the same but they certainly are not apples and oranges. I’d say they are more like oranges and tangelos. If we want significant greenhouse gas emissions, we’re going to need to ramp up renewable energy and quick.

Six Democratic Senators joined together on Wednesday to announce a comprehensive energy bill that would tax windfall profits and “force” investment in renewable energy.

Among other things, the Consumer-First Energy Act of 2008 would roll back tax breaks for oil companies and invest the money in renewable energy development and energy efficiency technology. It also would create a windfall profit tax on oil companies failing to invest in increased capacity and renewable energy resources.

According to one of the bill’s co-sponsors, Sen. Bernie Sanders (Ind.-VT):

“The bottom line is that at a time when this country faces a major crisis in terms of the price of oil, when many working families in our state and all over this country are hurting, I think we have brought forth a comprehensive piece of legislation, which begins to attack that problem with the result of lowering the price of oil.”

Today’s post is by Dr. Bill Chameides, dean of the Nicholas School of the Environment and lead author of the forthcoming blog The Green Grok. This is the second post in a 2-part series on biofuels.

Last week’s topic was why corn ethanol is an environmental loser.

But are all biofuels losers? No. Some can be winners. One of those is called cellulosic ethanol.

What Is Cellulosic Ethanol?

All ethanol — whether it is corn or cellulosic — is the same chemical compound: C2H5OH. You might recall from elementary chemistry courses that the “OH” group at the end of the formula indicates that the compound is an “alcohol.” Alcohols can have varying numbers of carbon atoms. Alcohol with two carbon atoms is called “ethanol.” The other alcohols are generally too toxic to be ingested, and thus ethanol has been the libation of choice down through the ages. (Ethanol used as fuel is rendered nonpotable.)

So corn ethanol and cellulosic ethanol don’t signify different types of ethanol, but rather the different material (or feedstocks) used to produce them.

Cool looking contraption, huh? What you’re looking at is Finavera Renewables’ latest project in scalable wave power technology.

Agency permanently extends comment period for alt. energy leases

In the fall of 2001, Jim Gordon of Energy Management Inc. (EMI) announced his intentions to build a 420 megawatt wind farm off the coast of Massachusetts - the nation’s first. Now, the long permitting process that was made even longer by powerful opposition groups, is nearing resolution…finally.

More than 40,000 individuals and organizations have submitted comments on an environmental review of the wind farm proposed for Nantucket Sound, according to an article in the Cape Cod Times.

“I’ve never seen anything like this before,” said Rodney Cluck, Cape Wind project manager for the U.S. Minerals Management Service, the lead federal agency to review Cape Wind Associates’ plan to build 130 wind turbines in Nantucket Sound, off the coast of Massachusetts. Originally, the comments were set to be released last Friday, but officials at the Minerals Management Service postponed the release to give agency staffers more time to organize the overwhelming public response to the proposed wind farm.

As a result of the scoping process’ popularity, the MMS announced that they would be preemptively extending the comment period for all of the remaining “Alternative Energy Leases” from 30 to 60 days.

A recent report by NPR news tells of a teacher at Lewis County High School in Weston, West Virginia who is determined to teach Environmental Science and keep politics out of her classroom at the same time. Tiffany Litton holds an undergraduate degree in Environmental Science. She decided to forgo pursuing a career in law to become a high school teacher. Why? Her goal is simple. She wants her students to be better stewards of the environment and felt she could have a bigger impact as a teacher than a lawyer. “My science class is not the place to promote any agenda, its the place to promote facts…” states Miss Litton to NPR news when being interviewed for this story. She has won the trust of her students by respecting their views and not preaching to them. Encouraging even those students who hold a different view than her own, she has been known to award A’s to those who can bring a well researched counter argument to the table.

The students are listening and learning. One father (who happens to be a coal mining equipment distributor) candidly remarked that he does not want his daughter influenced and becoming one of those “tree huggers”. His daughter, a student of Miss Litton’s, respectfully comments that in her opinion her father’s generation does not understand the damage that has been done to the environment.

After hearing President Bush blame Congress for our country’s high gas, food, and energy prices yesterday, I still wasn’t convinced that drilling in ANWR would solve all of our problems (note: sarcasm).

It turns out that voters, at least according to a poll of 1,200 Americans conducted by Peter D. Hart Research Associates Inc., feel the same way.

Not only did fifty-seven percent of voters rate energy issues as “very serious” concern, but they also thought investment in renewable energy was the best solution:

It had to happen, just when we were beginning to think that plug-in hybrid and electric cars were the best things since sliced bread, someone has intimated that there may be a health risk involved in driving those vehicles.

You remember, the power line scare back in the ’70’s (which really hasn’t gone away) and of course the more recent flap about cell phones emitting dangerous electromagnetic fields to the brain. In case you want to read more on these issues, a specific Google entry should suffice.Now, before you go somewhere else, hang on, there’s more to this electromagnetic field issue than you may think. That’s coming up, along with a short tip of the hat to the man who got us started on our way to the world we live in.

The giant wind turbines on the west coast of Ireland stand not only on the geographical limits of Europe, but also on the cutting edge of a revolutionary technology that makes wind power more reliable and valuable. The 32 megawatt (MW) Sorne Hill wind park will be Europe’s first to integrate a large scale battery back-up system that ensures a reliable supply of electricity regardless of how the wind blows.

“The battery enables large amounts of energy from wind or solar power to be stored, managed, controlled and sent into the electricity grid when it is needed. It doesn’t matter whether the wind is blowing or not; the battery makes the electricity output predictable and reliable,” said Tim Hennessy, CEO of VRB Power Systems, the battery manufacturer based in Vancouver, Canada.
