The more things change the more they stay the same. This Blog for instance will change at the beginning of the year. I am going to seek full time employment after working on Community Energy Systems for 6 years. I do not really know what that means. It could mean as little as 1 post a week. In an emergency like Katrina or the Gulf Oil Spew it could mean daily for awhile. Today I leave you with something I have seen up close and personal, the ancient Bristle Cone Pine tree.

Read My Rings: The Oldest Living Tree Tells All

November 13th, 2012

By Hunter Oatman-Stanford

n 1964, a geologist in the Nevada wilderness discovered the oldest living thing on earth, after he killed it. The young man was Donald Rusk Currey, a graduate student studying ice-age glaciology in Eastern Nevada; the tree he cut down was of the Pinus longaevaspecies, also known as the Great Basin bristlecone pine. Working on a grant from the National Science Foundation, Currey was compiling the ages of ancient bristlecone trees to develop a glacial timeline for the region.

“Bristlecones are slow-growing and conservative, not the grow-fast, die-young types.”

Currey’s ring count for this particular tree reached backward from the present, past the founding of the United States, the Great Crusades, and even the Greek and Roman Empires, to the time of the ancient Egyptians. Sheltered in an unremarkable grove near Wheeler Peak, the bristlecone he cut down was found to be nearly 5,000 years old, taking root only a few hundred years after human history was first recorded. How could a half-dead pine barely 20 feet tall outdo the skyscraper-height sequoias, commonly thought to be the oldest trees alive?

The longevity of Great Basin bristlecones was first recognized in the 1950s by Dr. Edward Schulman, who shocked a scientific community that believed in a correlation between long lifespan and great size. Schulman systematically sampled Great Basin bristlecones in California and Nevada, and published his findings in a 1958 National Geographic article, which revealed several of the trees to be more than 4,000 years old. Schulman’s analysis supported the idea that “adversity begets longevity,” or that the severe conditions in which the bristlecone pine evolved actually helped extend its lifespan.

There is so much wrong about this piece but I understand his sentiment. We have to get going soon or his children’s future and his grandchildren’s future are at stake. But that wouldn’t be true if he would have gotten the message 20 years ago.

Need to Be Big, Not Cute

To solve the world’s energy problems and combat a rise in global warming, the solutions need to be dramatic and powerful. And definitely not cute. That’s the blunt assessment of Bill Gates, who dismissed smaller scale technologies like residential solar installations as being “cute” but ineffective.

To solve the world’s energy problems and combat a rise in global warming, the solutions need to be dramatic and powerful. And definitely not cute. That’s the blunt assessment of Microsoft co-founder Bill Gates, who dismissed smaller scale technologies like residential solar installations as being “cute” but ineffective.

Speaking at the Wired Business Conference in New York, Gates sounded a now familiar call for innovation in clean energy production. But he said the challenge of meeting the world’s growing energy needs while reducing the rise of carbon emissions won’t be handled by smaller deployments of technology. For example, he said solar panels attached to homes and connected to smart grids is no match for the real impact of large remote solar installations.

With its breathtaking natural beauty and unlimited opportunities for outdoor recreation, a trip to Giant City State Park near Carbondale is sure to delight visitors of all ages. From camping and horseback riding to fishing and rappelling, it’s an outdoor lover’s paradise. Visitors will marvel at the many wilderness trails. Especially popular is a hike on Giant City Nature Trail, home of the “Giant City Streets” huge bluffs of sandstone formed 12,000 years ago .

Nestled in the Shawnee National Forest, just minutes south of Carbondale, the Union / Jackson county park was named for the unique impressions made by its massive sandstone structures. Eons of geological faulting and folding have molded a landscape like none other, which is now clothed in lush garments of fern, moss, large flowering mints, hundreds of species of wild flowers and 75-plus varieties of towering trees. The natural splendor of Giant City has made it a renowned retreat that attracts more than 1.2 million visitors annually.

But Garden of the Gods was amazing:

http://www.shawneeforest.com/Hiking/GardenoftheGods.aspx

More than 320 million years ago, the wind and rain patiently started to chisel away at large deposits of sedimentary rock located in what is now, Shawnee National Forest . Over the years, the elements have sculpted some of the most stunning and extraordinary rock formations known to man. This garden of sandstone sculptures and vast untouched wilderness was fittingly named Garden of the Gods.

The park contains a variety of plant and animal life, adding to the scenic beauty of the Shawnee Forest. Garden of the Gods covers more than 3,300 acres of forest throughout the Southeastern Illinois counties of Saline, Pope and Hardin. There are also plenty of trails for backpacking and horseback riding, allowing nature lovers a welcome tour of what the lively environment has to offer.

What Can Be Found on This Site

This site contains information about my books, an archive of my articles, and descriptions of my workshops on wind energy and Advanced Renewable Tariffs. This site also contains an extensive collection of articles and technical reports on electricity feed laws or renewable energy tariffs. I’ve been an outspoken proponent of feed laws since the late 1990s when I urged the American Wind Energy Association to call for them nationally.

Photography

My photos are stocked by Still Pictures in London. For more on my photography and for photo tours of several wind farms as well as a sampling of wind energy icons, see the photos section of this site.

 

Small Turbine Testing

Beginning in 1997 I’ve measured the performance and noise emissions of small wind turbines at the Wulf Test Field in the Tehachapi Pass. For more information on this work, visit Wulf Test Field.

Wind Power In Germany – Killing time until the presidential election is over

Yes it is true I am distracted by world events. But to be fair to wind power they are tearing it up in Germany.

The Green Republic? Germany’s Wind Energy Boom

Published: October 8, 2012

The German wind industry sits at the heart of a European energy market preparing for a disruptive transformation intended to promote integration and allow the rich wind resource of the North to fuel continent-wide growth, without the risks of nuclear power and reliance on foreign energy producers.

It is a comprehensive, ambitious vision that in Germany alone the environment minister Peter Altmaier has compared in scale to the country’s painful post-Communist reunification.

The EU is preparing to release its latest communication on an integrated energy market ahead of a goal of operational integration it has set for 2014. The energy market remains one of the rare nation-state functions that has hardly been impacted by European integration at all, despite the EU’s origins in a post-WWII agreement over the continent’s coal sector.

The Future Of Solar Is Uncertain – At least at the utility level

Not much to say about this. Conference summaries are always difficult to interpret. You miss all the personal conversations, updates, and sense of the future. Still it is a snapshot.

Utility-Scale PV Developers Confront Future of Solar Project Business

They want the “doable renewables.”

Herman K. Trabish: November 1, 2012

Building utility-scale PV solar projects is getting tougher. Greentech Media’s U.S. Solar Market Insight conference concluded with a discussion between experienced developers about the challenges and opportunities.

Moderator and GTM Research Senior Analyst Shyam Mehta asked them to first review the last year.

“In summer of last year, the IOUs issued RFPs, the first in over two years,” 8minutenergy CEO Martin Hermann recalled. “More than 70,000 megawatts of applications were submitted. They shortlisted about 2,500 megawatts.”

The ISO queue has dropped from 80,000 megawatts to 50,000 megawatts and utilities are “looking very diligently to see if there are any show stoppers” before signing contracts. In this “tough competition for PPAs,” Hermann said, developers are “monetizing or cancelling their portfolios.”

In three years, explained SunEdison (NYSE:WFR) General Manager Attila Toth, the U.S. solar market will be 50 percent distributed generation and 50 percent utility scale projects. But about 85 percent of the 3.5 gigawatts to 3.8 gigawatts of utility projects “is already spoken for, in the queues and has company’s names written on it. There is a very limited opportunity in the utility segment.”

New Solar Plan Should Speed Things UP – If you care about this planet

Plan to streamline solar development in West OK’d

By JASON DEAREN Associated Press

SAN FRANCISCO—Federal officials on Friday approved a plan that sets aside 445 square miles of public land for the development of large-scale solar power plants, cementing a new government approach to renewable energy development in the West after years of delays and false starts.

At a news conference in Las Vegas, Interior Secretary Ken Salazar called the new plan a “roadmap … that will lead to faster, smarter utility-scale solar development on public lands.”

The plan replaces the department’s previous first-come, first-served system of approving solar projects, which let developers choose where they wanted to build utility-scale solar sites and allowed for land speculation.

The department no longer will decide projects within the zones on a case-by-case basis as it had since 2005, when solar developers began filing applications. Instead, the department will direct development to land it has identified as having fewer wildlife and natural-resource obstacles.

The government is establishing 17 new “solar energy zones” on 285,000 acres in six states: California, Nevada, Arizona, Utah, Colorado and New Mexico. More than half of the land—153,627 acres—is in Southern California.

Solar Panels Go Plastic – Light weight and easy to mount, what’s not to like

Here is the MIT report.

http://www.technologyreview.com/news/428423/new-solar-panel-designs-make-installation-cheaper/

 

New Solar Panel Designs Make Installation Cheaper

Companies in Germany and China have made simpler designs that make it easier and quicker to mount panels to roofs.

With solar panel prices falling more than 80 percent in the last few years, many solar companies are turning their attention to reducing the cost of installing them. Two leading solar companies, Solon Energy, based in Berlin, and Trina Solar, based in Changzhou, China, have announced new designs for mounting solar panels to roofs—the companies say these designs can reduce the installation time by more than half, greatly reducing labor costs. The new designs reduce or eliminate the tools and hardware needed to install solar panels, and standardize solar installations, which have largely been ad hoc, reducing the time needed to design them.

While solar panels themselves used to account for most of the cost of large solar installations on commercial rooftops, the modules now account for about 40 percent of the cost. The rest comes from things like the necessary hardware, power electronics, and labor—which alone accounts for about 30 percent of the total.

Mounting solar panels on the flat rooftops of commercial installations typically involves anchoring long metal racks to the roof to create a framework that will angle the panels toward the sun and hold them together. Installers bolt the panels to this frame, wire the panels together, and electrically ground the racks.

Solar energy is ready, the U.S. isn’t

By Ken Wells
Published 5:07 p.m., Sunday, October 28, 2012

Clean energy has become a dirty word in presidential politics.

In their second debate, Mitt Romney and Barack Obama each tried to outdo the other’s love of fossil fuels: Obama extolling his record on oil and natural gas production, Romney vowing to take “advantage of the oil and coal we have here.” The Republican candidate has ridiculed the administration’s $535 million loan guarantee to Solyndra, the bankrupt solar panel maker, and accused Obama of living “in an imaginary world where government-subsidized windmills and solar panels could power the economy.”

The candidates’ coolness to renewable energy comes at a time when the domestic supply of traditional energy sources, such as oil and natural gas, is at an all-time high. And yet this failure to make the promise of renewables a keynote in the debate is a huge missed opportunity. In particular, it ignores the dramatic reduction in the cost of photovoltaic solar power worldwide and the considerable benefits to U.S. consumers and the environment.

Political roadblocks

The untold story of this campaign is that what killed Solyndra may turn out to be a boon for the nation. “Economically and technologically, the game is over,” said Bill Powers, a San Diego engineer and board member of Solar Done Right, a group that proselytizes for rooftop solar power. “The hang-ups in the U.S. are strictly political.”

Over the past five years the price of photovoltaic panels has plummeted 75 percent, due largely to a glut of Chinese-made panels. The fall in prices rendered technically advanced photovoltaic panels, like those produced by Solyndra and other U.S. companies, too expensive to compete.

Solar Islands – This is a great concept

They say nothing about storms or ship traffic so I am not sure how this would work in the real world.

Floating solar islands designed to power crowded cities

By on 29 October 2012

Not to be confused with what could be the biggest storm ever to hit the United States, SUNdy – a large-scale offshore solar farm concept by global consultancy and certification firm DNV – was unveiled at Singapore International Energy Week on Thursday last week.

The core feature of the floating solar concept is a hexagonal array of 4,200 solar panels – roughly the size of a football pitch – which floats on the sea’s surface. The ‘solar island’ would be capable of generating 2MW of power, with multiple islands joined together to create an offshore solar field of 50MW or more, producing enough electricity for around 30,000 people.

“The island has been optimised for solar capability and cabling efficiency,” says Kevin Smith, Global Segment Director for DNV KEMA’s Renewable Energy Services. “The solar arrays are divided into electrical zones feeding electricity produced into two main switches collecting the power for voltage step up at a central transformer (2MVA 480/34.5kV). From the offshore solar farm’s central island, 30kV electrical transmission lines connect, tying other islands in series to form a close loop and continue to the electrical sub-station onshore for grid connection.”

Sanjay Kuttan, managing director of the DNV Clean Technology Centre in Singapore says SUNdy’s thin-film 560W solar panels are flexible and lighter most silicon-based modules, allowing them to undulate with the ocean’s surface. “The key to creating an ocean-based structure of this size is the use of a tension-only design. Rather like a spider’s web, this dynamic, compliant structure yields to the waves, yet is capable of withstanding considerable external loads acting upon it.”
