California Approves First US Energy Efficiency Standards for Computers
The new standards, approved by California's Energy Commission, requires most computers to draw less power while idle. Laptops are only required to see a slight reduction in power draw since they're already designed to be energy efficient. But only 6% of desktops currently meet the commission's standards. On average, noncompliant desktops will have to reduce their idle power draw by about 30% by 2019 and by about 50% by 2021, the commission says.

An Update on California's Distributed Energy Leadership
In a unanimous decision yesterday, California regulators created a new financial incentive pilot that encourages utilities to invest in DERs instead of more expensive traditional grid investments.

Microgrids Continue to Progress - With Some Bumps in the Road
Microgrids increasingly are being seen as a hedge against grid failure and as a way to more efficiently harness renewable resources. However, there is uncertainty for the future of microgrids as they grow at different rates in different areas and with potential decreases in research and development with the new Administration.
NYC Hospitals Reduce Energy Use by 10%

2.  AB 2188 Ordinance Adoption

The Solar Permitting Efficiency Act, signed into law by Governor Brown in September 2014, requires California cities and counties to adopt an ordinance that creates an expedited solar permitting process by September 30, 2015. The Solar Permitting Efficiency Act modified specific statutes that compose the Solar Rights Act and requires cities and counties to substantially conform their streamlined permitting process to recommendations contained in the current version of Spring 2015 Second Edition of this Guidebook lays out a safe, standardized, and streamlined permitting process for small residential photovoltaic (PV) and solar water heating systems (SWH) that can be adopted by most local governments with only minor changes to reflect local requirements.
To support local governments in achieving the ambitious goals set by the Solar Permitting Efficiency Act, the Governor’s Office of Planning and Research (OPR) has been working to remove barriers that constrain expansion of small-scale renewables. The Solar Permitting Guidebook is an important step toward this goal. The Guidebook explains current requirements for small residential solar PV and SWH installations, describes key steps in the permitting process, and recommends ways to improve local permitting. It also includes several template documents that local governments can customize for their own use to improve permitting. The Guidebook can also provide useful information to solar contractors and property owners.
Please visit the OPR webpage to view the Solar Permitting Guidebook, download editable Toolkit documents, and find additional information and resources related to solar and renewable energy. For more information, please contact Carolyn Angius at Carolyn.Angius@OPR.CA.GOV.

3.  Google tool to Help Install Solar Rooftop Panels

A team of Google engineers just released a tool called Project Sunroof to handle those concerns and more. They adapted the high-resolution aerial maps from Google Earth to estimate the total sunlight a rooftop receives throughout the year. The tool then tells you how much you can expect to save with solar panels under different financing plans (you can plug in your current electric bill for a more refined calculation) and connects you with local companies that do installations.  The tool covers limited communities at this point, but will be expanded in the future.

And that is all for this week!  

The Green Teams Part III

See? It's just so pretty!
Photo Source: http://levisstadium.com/
I was in San Francisco for Super Bowl XLVII; it was devastating. I’ve never seen the city so depressed. There’s hope for 49ers fans, though, as well as a new, shiny stadium. Santa Clara is their new home and, boy is it beautiful. It’s crazy efficient, too! There is a 20,000 square foot green roof… I know, SO cool. The stadium is using reclaimed water for drinkable and irrigation purposes and has incorporated recycled materials into the design. The stadium is also partnering with local vendors to create farm-to-table options for ticket holders. How awesome is that? And in addition to these already ground-breaking inclusions, a local company called SunPower is partnering with the new Levi’s Stadium to supply enough solar panels to produce sufficient electricity to compensate for all the power used for home games each year. True story.

I think (I hope!) the publicity of this installment as well as the one at the Pocono Raceway will help convince solar-naysayers that this great country we live in CAN produce ample amounts of renewable energy and maybe we should start viewing it as a reliable and clean supplier of grid power. I understand there’s a high initial cost, but there are loan and third party programs out there, among others. If solar can be implemented and rewards can be reaped on such a huge scale AND in a setting we all enjoy and support daily as a united community, we should be able to incorporate it on a smaller scale, too, without so much backlash, don’t ya think?

Speaking of renewable energy on a large scale, Progressive Field, home of the Cleveland Indians, installed solar way back in 2007 (the stadium was one of the first in the US to do so). The Indians have really been getting after energy savings through green initiatives. The stadium was also the first in the MLB to install a wind turbine. Installed last year, the turbine incorporates LED lights and kiosks for fans to learn about wind energy. See Mom, sporting events can be educational, too! Furthermore, staff attends an annual class about the stadium’s newest green practices, encouraging them to implement their knowledge at home and in their communities. Start on a small scale and cause a chain reaction… I’ve always believed this is the way to get people on board to save the environment!


The Indians also have some great ideas for future projects, which include following in the footsteps of the 49ers and building a green roof. I know I’ll probably be judged and condemned for saying this, but even though popcorn and hotdogs are the staple snack at baseball games, I am a sucker for fruit right off the tree and veggies right out of the ground. I would be more than happy to pay $20 for that and be able to pick it myself IN THE STADIUM than pay that kind of money for some processed meat and watery beer (sorry Keystone and Miller Light lovers! I’m really just not into it. The commercial above is more up my alley.).  Want to read more about the Indians and their energy-saving super powers? See pages 69-72.

NHL fans, I have not forgotten about you! Plus, even the NCAA is implementing sustainability programs. The big leagues aren’t the only ones who get to have all the fun! Stay tuned, loyal followers. More energy efficiency in sports to come!

The Green Teams Part II

I try to be energy conscious and waste as little as I can. Then again, I am lucky to live in a part of the country that allows me use public transportation (or walk) to almost any destination, does not have air conditioning in any apartments and has compost and recycling bins nearly everywhere. (For those of you that don't know, I moved to Seattle! and am happily still working full-time for the Clean Energy Organization.) I never use a hair dryer for more than a few minutes and only run big appliances (laundry, dishwasher) after peak hours. My microwave and stove get used once a day, max. But this is energy use on a very small scale for one very small person. 


SCREAMS inefficiency

So what happens when, instead of being in charge of just your own energy use, you’re suddenly in charge of hosting tens, even hundreds, of thousands of fans (who are hungry and thirsty, cold or hot, and may be seated far from the action of the game) in a stadium that holds all of these people, food and ticketing staff, security plus the stars of the event and their managers, coaches, team owners, etc? Not only is there a need for several food and beverage booths, powerful HVAC systems, jumbotrons, surround sound speaker systems, expansive locker rooms, and numerous multi-stall bathrooms, but everything (and by everything, I mean every nook and cranny) has to be brightly lit and perfectly air conditioned. That sentence included A LOT of energy-draining things, which can only mean that the energy needed to power all of them is nothing shy of A TON. And as I mentioned in Part I of this mini-series, it seems hypocritical to live as I do and work where I do when I also snatch up every opportunity I get to go to one of these events.

We energy-enthusiast sports fans got lucky, though, because the industry has been significantly decreasing its energy use for a few years now. At this massive scale, energy use will always be high, but hosting these events in a LEED building or incorporating solar panels does make a difference. Take the Pocono Raceway in Pennsylvania for example. In 2010, 40,000 solar panels were installed; they power the entire facility and cut the raceway’s annual energy bill by over $500,000! That’s a lot of savings! It was also the first raceway to participate in the Dream Machine program, which provides a fast and easy way for fans to recycle. You can read more about these and other green initiatives here; and think about incorporating similar practices yourself because as the Raceway itself declares, “it’s not that tricky”.

I've been playing tennis for nearly two decades now and learning that the US Open Tennis Center in Queens has been going green since they launched a pilot program in 2008 with NRDC (thanks to the amazing Billie Jean King, see pages 24-26) made me very ecstatic indeed! Initiatives cover recycling, transportation, energy management, and many more facets of the jam-packed two-week event, including event merchandise. The Center reduced water flow by 75 percent (!!!) in 2011 with new low-flow faucets; all match balls are reused in summer camps or donated to community organizations; all tennis ball canisters are taken apart so each metal and plastic component can be recycled separately and correctly. Plus, the Center composts almost all of its waste, down to the cooking oil. What does this amount to each year? HUGE savings and hundreds of tons of waste diverted from landfills. Can’t beat that!


NFL and MLB fans, stay tuned for Part III!


Solar And Water: A Growing Combination


*Editor's Note: I was cleaning out the SJVCEO blog archives last week and came across this draft post authored by the one and only Sandy Nax!  Going by the date of the draft I can only figure that Sandy had worked on this prior to his departure from SJVCEO in May 2012 and never had a chance to hit the 'publish' button. So, Sandy I hope you don't mind our using your words one more time!  -CBK

Many people equate solar power with rooftops, and that's true. More property owners - commercial and residential - are installing solar panels over their heads to cut power bills and carbon footprint. Check out what Toys 'R' Us is doing in New Jersey.

But solar energy is popping up all over the place. In backpacks. With the military in Afghanistan. On parking structures and as window coverings. And, increasingly, on or around water.

Solar is appearing at wastewater treatment plants, vineyard irrigation ponds and in settling ponds at gravel mines. There is even research into getting solar power from the ocean.

This New York Times story, which I read in the San Jose Mercury News, notes that solar panels are sitting atop pontoons at Far Niente in Wine Country. It quotes a winery official saying that vineyards are expensive real estate, and placing a solar array on the pond means no vines are removed.

Solar energy systems also are gaining a following at wastewater treatment plants here in the San Joaquin Valley, where power bills run high in the blazing summer.

The cities of Tulare and Madera use solar at their plants. Learn more about those projects here and here. Water transfer is expensive, and solar can help cut costs. We keep hearing that more cities are considering following suit. This Sign on San Diego story has more on how solar works at such plants.

Opportunities for solar will become even greater as technology improves, costs decrease and it becomes more mainstream. Water-related solar increases those possibilities even more.

Sandy's now in Sacramento working for the California Department of Toxic Substances Control and still managing to write...a lot.  Seriously, Google it!

Whitepapers: PV inverter performance in desert-like locations


Wow, unique desert challenges addressed through rigorous testing!

On April 25, 2012 SMA America, LLC publish a study on how outdoor installed PV inverters held up under extreme weather conditions found in the desert. Conditions such as sandstorms and enormous temperature swings produce a whole new set of challenges for developers of PV inverters. Dust and sand is prevalent in the ambient air and tends to create serious obstacles in solar PV inverters installed outdoors, but with the new technology developed and rigid testing the inverter’s seals protected it from harmful dust deposits.

I don’t know about you but this stuff gets me excited. I’m really enjoying watching alternative energy develop in front of me.  We are indeed watching history in the making, but let’s not forget that energy conservation, although not the most attractive option is the best way to become energy independent. Check out the full story at the link below.

Some of you may know Shalon, at least by name, through the US Green Building Council Central California Chapter.  In addition to her work for USGBC CC, Shalon works in support of many of our clients in the non-sustainability fields at PESC.  Shalon was interested in trying her hand at blog writing and we're fortunate to be the only blog business in the office!   How is this a Money Monday post?  Well,  that's answered in reason #1!


Thinking about solar for your home?
By Shalon Anderson

There are many myths out there about solar panels. “They’re too expensive, They don’t last long, It’s a waste of time.”

Well- the truth is, there are many reasons why installing solar panels on your roof can save you money and reduce your energy dependence! Solar is one of the very few household purchases that will actually pay for itself. There is no better way to save money AND increase the value of your home at the same time.

Don’t just take my word for it, let’s review the top 5 reasons why installing solar panels on your home makes financial sense.

1. GO GREEN! Installing solar panels offers a “greener” alternative than energy obtained through utility companies. Once your solar panels are installed, (roughly 3-5 days depending on the size of your home) you will immediately begin to save $$$$ on electrical costs. These savings will rack up for years to come!

2. AFFORDABLE! Most solar dealers offer little to no money down for initial  costs. Financing is available for homeowners and it’s always a good idea to check out the local incentives and rebates in your area. They’re out there! What happens if you move or sell your home? No need to fret! Nearly all solar contracts can be transferred over to new owners at no cost. See your local solar dealer for full details.

3. RELIABLE! Solar panels are built to withstand years of direct heat. On sunny days, the solar panel’s battery is charged giving you hours of efficient power after sundown.  According to gosolarcalifornia.org, photovoltaic (PV) panels should last 20-25 years or longer. Maintenance is quick and easy, with nothing but a spray of the good ol’ garden hose needed once every few years.

4. NO FUSS! There is no interruption of solar power in the dim light or on overcast days. Solar panels are built to work with your general utility grid in times of harsh weather. You can connect to the grid when needed, so no loss of power will be experienced. You can continue with your normal activities without a sweat. In times of blackouts, solar panels will automatically turn off to prevent interference with utility company repairs. 

5. WHY NOT? There’s no reason not to consider solar panels! They can be installed in a timely manner with no modifications needed inside or outside of your home. Your roof will never  be subject to damage because solar panels actually protect the part of the roof they cover. It’s a good idea to have your roof inspected for any necessary repairs that may be needed prior to installation. Once installation is complete, all appliances will go back to “business as usual”. There is no need to purchase new appliances or acquire any special electrical outlets.

Your green home is just a phone call away! Be sure to make a list of questions and concerns for your sales person. Contact your local solar panel dealer for more insight and tips on how you can start saving money today!

Space-based clean energy could alter the future

Harry Harrison at his best.
Clean and cheap energy has been percolating in innovators' minds for centuries.

Far longer ago, alchemists and wizards sought the source of ultimate power somewhat differently, calling it magic.

The economic consequences of cheap clean energy would be tremendous. Imagine energizing rural Africa or infusing India's poorest neighborhoods with uninterrupted inexpensive power. All that brain power just waiting for an opportunity to connect with a money-making idea could make substantial changes in technological development, not to mention economic might.

So far, however, that pursuit remains unrealized. Recall cold fusion? How about the mythic magnetic power generator, a device that purports to produce "free" electricity.

Alas, it's a crock. So far, anyway.

Pursuing clean energy

That doesn't stop the pursuit of some nearly free energy source. Or the daydreaming. Or the bona fide research bringing existing clean energy technologies more in line with the cost of conventional carbon-creating fuels.

Writers regularly take on the challenge, imagining star travel as the likely result of conquering energy. Isaac Asimov's universes were fueled by atomic power. Even Albert Einstein and Otto Stern envisioned a hidden source of power in all things. They called it Nullpunktsenergie, which was later translated to zero-point energy. Imaging that is one thing. Tapping it is another.


With this in mind, I decided to do some research. For mean that meant looking up the sci-fi masters. Of course, clean energy wasn't the only thing on my mind. Reading offers equal-opportunity inspiration.

Back to the barn

Used book stores exude a musty eclectic chic. Often they're stuffed with type-packed cast-offs just waiting for somebody to give them another look.

At the recently expanded and somewhat aptly named Book Barn in my town of Clovis, Calif. I tagged along as my high school English teaching wife, Peggy, scoured the shelves for teen lit. Werewolves, vampires, angst and drama. The usual stuff.

Meanwhile, I hit the science fiction shelves. I dug around in the recesses of my memory for authors I once read and scanned the carefully sorted titles. Good lord, Gardener F. Fox had a couple of books. He wrote in the style of the incomparable Robert E. Howard, creator of Conan the Barbarian. Fox's publisher didn't have anything on the author in the series of skinny little paperbacks available, so it's not surprising he's totally out of print today.

I nabbed one, even though it read like something I had consumed before. Many times before.

Charlton Heston's legacy

On the next shelf over, I found several by Harry Harrison, who startled my generation in 1966 with the story, "Make Room, Make Room," which explores the consequences of unchecked population growth. Most recall the somewhat altered movie version, "Soylent Green," starring Charlton Heston in the leading role of detective Thorn and Edward G. Robinson as his roommate Sol. It was to be Robinson's final film.

Harrison has penned a number of novels in various sci-fi sub genres, and many contained themes of social commentary. Although not so much with the "Stainless Steel Rat," a space criminal anti-hero who had a bit of a soft side. I believed I had consumed nearly all of his books but found a couple in the Book Barn that proved me wrong. "Invasion Earth" tells the story of an invasion by aliens by means of a high-stakes con job, and "Skyfall" outlines the struggles of a U.S.-Soviet (the Reds still had stamina in this 1978 novel) project to ship a deep space solar collector into the heavens to provide clean, cheap energy to the the globe.

In "Skyfall," the project isn't easy. In fact, disaster lurks at just about every turn. Not surprising. Actually, the story is somewhat timeless, other than the Soviet connection. Swap CCCP characters for Russians and it could spark interest a decade from now when climate change is a freakish reality, sending residents of island nations and low-lying countries like Bangladesh into their neighbors' garages and outbuildings.

"Skyfall" isn't Harrison's best. It drags. Its characters have all the zip of a lead brick. The pilot is an idiot chauvinist. The U.S. president is a jerk, not as "crooked as Tricky Dicky, but he's craftier." The Russian female pilot is underdeveloped and somewhat two-dimensional. The narrative doesn't zing like most of the author's work.

Space-based solar

But the Prometheus Project sounds great. The idea is to deploy huge unfurling solar collectors where they could collect solar energy without nighttime interruption and beam it via microwave to points on earth. The cost is immense and the project massively controversial. The book's antagonist is a Newsweek reporter who wants to write about nothing but potential doom.

Coretta Samuel, one of the crew, tells him at one point, "Just the physical reality that, at the present rate of consumption, we're going to burn up all the Earth's oil in a couple more years. So we've got to do something drastic about it."

Doing something. Sounds great to me. Back when this book was published, I was thinking about earning gas money for my mini truck and enjoying the spoils of refined fuel while spinning broadies in the East High parking lot in Anchorage.

Current political discourse has all but ignored climate change. That's an issue for our children, apparently. They will have to make the tough decisions because there will be no alternative. Most likely they will curse the previous generation for short-sightedness.

I know I would.

Solar solutions

There is an alternative. Investment in a number of solar projects will reveal over time that there is money to be made in clean energy. There's certainly economic development in clean energy. Spending on facilities that continue to generate money in the form of electricity offer a steady payoff as well as the initial injection of construction jobs.

Just as a wider road or bridge facilitates travel and movement of goods and services, clean energy facilities generate energy without the constant effort of the extraction of natural resources. Drilling will recover only what history has left. Mining for coal will get increasingly expensive as the easy-to-extract sources play out, while oil recovery is already tapping the tremendous technological talents of engineers.

Federal dollars should continue to be funneled into clean energy research. You never know what some grad student will pull out of a beaker after long nights and neuron-firing inspiration.

The National Space Society promotes the concept Harrison wrote about in "Skyfall." Maybe it's not far-fetched. It's definitely massively expensive and would require almost worldwide coordination of resources.

Space Office study

An October 2007 study by the National Security Space Office says the U.S. Department of Energy and NASA have spent about $80 million over the past three decades study space-based solar. In contrast, it says the U.S. government has spent about $21 billion studying nuclear fusion.

The study concluded that space-based solar "does present a strategic opportunity that could significantly advance U.S. and partner security, capability and freedom of action and merits significant further attention on the part of both the U.S. Government and the private sector."

The study also says while significant technical challenges remain, the concept "is more technically executable than ever before and current technological vectors promise to further improve its viability."

Intriguing.

Sounds a little like I read this somewhere. Oh yeah, in just about every book I consume. Hugh Howey is my latest favorite author. His "Bern Saga" series takes energy sources, space travel and future economic and cultural conflict and turns everything inside out. His concepts stretch my imagination, certainly.

Possibly, Howey and others writing quietly in their home offices will change the direction of mankind. For the better.

Off the grid: TV tries on extreme energy efficiency

The cast of Falling Skies.
The Twilight Zone episode "The Midnight Sun" chronicles the last days of Earth through the eyes of two women.

Stuck in an apartment building, they try to hang on as the planet heats to an inferno.

A man with a gun steals their water, which is invaluable as most of it boils off into the atmosphere. He apologizes. Then the thermometer bursts, oil paintings melt and the women pass out.

A surprise ending reveals that the earth is actually spinning away from the sun, becoming inhospitably cold. The overheated scenario is revealed to be a fever-fueled nightmare of one of the women. Everybody's going to die but by freezing, not frying.

A darker view of the future

That TV show originally aired Nov. 17, 1961, near the height of the Cold War when many could see the end of the world, or at least imagine it. The Twilight Zone was hardly alone reflecting the fears rife within popular culture. Horror films with political overtones experienced a renaissance. The anti-hero emerged. And negative realism supplanted much of the just-so attitude of the previous decade.

The economic collapse, the unknowns surrounding climate change and the threat of a finite supply of fossil fuels appears to be giving rise to similar doomsday sentiment. TV has taken up the challenge of answering the question: "What if life as we know it collapsed?" with a couple of slickly produced shows.


But 21st century popular culture doomsday isn't obliteration, it's discussing life without the grid -- a grim return to civilization without the niceties of electronics or central government.

Falling Skies

Watch "Falling Skies" on TNT for a glimpse into life without modern conveniences and an alien invasion threatening every remaining human. Every scene has a dark cast, while the stars worry about their next meals and never seem to have time for a shower.

The stand-out character is Colin Cunningham, who plays longhair and all around bad boy John Pope. Pope knows nothing is like it used to be and acts accordingly. His humanity, not all that sophisticated to begin with, gets tested occasionally with the sometimes soap opera story lines. But he comes through in a pinch when survivors need a weapon to kill the invading "skitters."

Soon NBC will debut  "Revolution," a J.J. Abrams drama centered around doomsday. This time all electronics fail and the United States is plunged into a world better suited to 19th century lifestyles. Of course, the transition likely wasn't so fun with cities full of desperate and starving people, so the show begins at year 15 when "life is back to what it once was long before the industrial revolution: families living in quiet cul-de-sacs, and when the sun goes down, the lanterns and candles are lit."

Of course, that won't last. Conflict is certain as, well, the next episode.

A beginner's guide

Chris Neiger jumps right into the issue writing a beginner's guide to living off the grid.

Neiger offers a straightforward approach. His target audience is the weekend enthusiast, the type who would like to experience a step back from technology and civilization but still keep it close.

"Some have already made the switch," he writes, adding that many more are considering severing ties.

Makes sense, especially in the eastern half of the United States where a major storm knocked out power at the end of June 2012. Residents lived days with stifling hot homes, backed up traffic because the lights didn't work and an economy reduced to old-style ledgers and hauling water because the pumps don't work. Refrigerator dumping was a must. A massive storm knocked down utility poles like toothpicks and cut power to an estimated 1.8 million.

Those folks got a taste of what could be. Most would prefer that the authorities keep the peace, that utility workers put up new poles and string new wire.

Fun with electromagnetics

But what if some terrorist organization set off an electromagnetic pulse bomb (a scenario chronicled beautifully by author Theresa Shaver in her book, "Land") or if the sun sent a massive solar flare our way?

Dan Vergano of USA Today describes an EMP this way: "Whether powered by geomagnetic storms or by nuclear blasts, their resultant intense magnetic fields can induce ground currents strong enough to burn out power lines and electrical equipment across state lines."

Nice. Like that, we go from civilized to candle power.

Of course, this kind of situation has nothing to do with the living green. But if the above scenario took place, the practice would indeed have merit. Sure, some now may be considering an alternative energy lifestyle. But they appreciate the finer things we've developed as a nation. My use of doomsday is for illustrative purposes only.

What would it take?

Being forced into alternative energy is hardly optimal.

Neiger's piece did make me think, however.

He spells out what it takes. First you'll need power. The average American home uses 11,496 kilowatt hours of electricity, according to the U.S. Energy Information Administration. Neiger suggests combining wind and solar systems. Not that this setup would be immune from a natural or wartime electromagnetic blast. But it could likely be repaired. I advise adding some backup lead-acid bus batteries.

The off-grid home also would need access to water. This can be done through a well and a submersible pump, which requires power. Waste water needs a septic system. Gray and black water can be separated, reducing the load on the septic tank.

Then there's heat. Neiger suggests propane, which can be delivered cheaply and would also be used for the cook stove, a water heater and fridge. A very reliable alternative for heat is wood. Modern wood stoves reach an extremely high interior heat, reducing smoke. Tip: well insulated homes need less fuel to heat or cool.


"Many people who go off the grid make gradual steps to energy self-sufficiency," Neiger writes. "It starts with conservation and then snowballs into alternative energy sources."

Neiger says to expect to spend money. And that's true. However, the more basic package is relatively cheap.

On O'Connor Road

I grew up off grid. Really not that big a deal. Were civilization to collapse when I was a kid living in the sticks in Fairbanks, Alaska, I suspect we'd be fine. I'd get a little more sick of salmon, moose and rabbit, but not much else would change.

We had multiple buildings, super-insulated and not real big. We had a septic tank for gray water. That's sink water by the way. The outhouse required a 50-foot sprint on cold days. Mom bought the 10 acres for $7,500 in 1970 and built an 18-by-32 foot two-story house, a separate eight-sided sauna and barn for about $18,000. Expect to pay more today, but keeping it simple reduces costs.

We melted snow in winter, collected rain water in summer. We did get electricity, but many of our neighbors lived too far to afford installing poles. They used candles and kerosene.

We heated our house with wood. I cut it up in summer, split and stacked it in massive piles and burned it when the snow started to fly. Some neighbors used coal from the Usibelli Mine delivered once a year.

A post by Spy Vondega on offgrid.net says, "Some of those who opt for the simple life are driven by environmental concerns or religious beliefs; others fear economic collapse; and some just enjoy hunting and fending for themselves."

And some may choose to do it as an investment.


Fellowship of the sun: Quest for solar power continues

Chronicling the progress of solar energy has at times been like trying to follow Legolas, Gimli and the rest of the Fellowship of the Ring as they journey across Middle Earth.

Here's a possible dispatch from soon after their initial departure: They've gone through the Misty Mountains and successfully beat the odds in the mines of Moria. But Gandalf dies battling a balrog.

Likewise, solar continues to push forward despite tremendous odds: U.S. manufacturers have been buffeted by international market forces but battle through. Solyndra is killed by a beast known far and wide as bankruptcy.

It's not easy. Yet, in both cases, the quest continues. For fans of J.R.R. Tolkien, the quest will never be over. My 15-year-old son currently carries a copy of "Return of the King."

For solar, the news on the whole is positive. Clint Wilder, senior editor at market analyst Clean Edge, says in a recent post that "U.S. solar installations grew 109 percent, adding 1,855 megawatts." He says that's thanks to "falling photovoltaic prices, favorable policies in key states, and the aggressive business strategies of installers/financiers like Solar City, SunRun, and SunEdison."

The battle for solar

That's not saying there's not a Battle of Hornberg at Helm's Deep still out there. (Recall in the Peter Jackson film "The Two Towers" where the fellowship whips up on bloodthirsty orcs in what has got to be one of the best fight screens in all moviedom.)

Solar progress in California's San Joaquin Valley has mirrored that in the rest of the nation. Development may not be as fast, but projects are getting green-lighted. The California Energy Commission shows 4,242.5 megawatts worth of major solar energy generating projects approved in the past several years and another 1,500 megawatts under review.

In the meantime, smaller projects are going in all over the state and the rest of the country. Here in the Valley, it's no different. But some spots are more progressive than others.

Signs point to job growth

Hector Uriarte at Proteus Inc. in Visalia says solar projects have begun to hurdle the permitting process and break ground, especially in Tulare County. “We have an 80 percent placement rate,” he said of his organization’s solar panel installation training program.
That placement rate represents a 20 point increase from about a year earlier at his organization.

Uriarte says the solar industry is very close to being a significant driver in the job market. “Once it breaks open, the need (for workers) will be tremendous,” he said.

Damon Silva of Bakersfield-based A-C Electric Co. said the utilities will play a big role in how fast solar projects materialize and begin to become a major driver in the San Joaquin Valley economy. “A lot of this has to do with the utilities themselves,” he said. “There are quite a few of our projects ready to go.”

Utilities must approve an energy project's link to the grid. That power has to meld seamlessly with existing sources and not overtax overhead, or underground, cables.

Educators seek to meet the need

The expansion in the industry means a need for jobs. The San Joaquin Valley's colleges have formed a group dubbed the Central California Community Colleges Committed to Change, or C6, to meet that demand. The program seeks to create accelerated educational training programs that produce qualified graduates for jobs in critical sectors that industry desperately wants to fill.

One of the targeted sectors is alternative and clean energy. The group is looking to form training and educational programs that build upon common curriculum that potential employers can depend upon. Discussion by the group at a recent meeting about clean energy focused on producing graduates fluent in the fundamentals and expanding from a solid base curriculum.

There is great potential. For instance the market for energy efficiency, which dovetails with solar, is huge. Steve Earl, president and CEO of Sequoia Energy Services, says he’s come across reports that indicate meeting California’s improved building standards for energy efficiency in new and retrofit structures would cost $90 billion. However, the projected return is $400 billion in savings.

Failure is not an option

The need to clean up our air is tremendous. In other words, the fellowship of the sun must not fail. My Precious, best known as Gollum's ring, for purposes of comparison, represents in this case fossil fuels. Spellbinding and useful but ultimately deadly.

The National Oceanic and Atmospheric Administration reports that six monitoring stations up in the Arctic reveal what clean energy advocate 350.org has been saying all along, that concentrations of carbon dioxide in the air are increasing. Sampling at those sites showed concentrations exceeding 400 parts per million in spring for several years.

"The northern sites in our monitoring network tell us what is coming soon to the globe as a whole," Pieter Tans, an atmospheric scientist with NOAA's Earth System Research Laboratory in Boulder, Colorado, tells procon.org. "We will likely see global average CO2 concentrations reach 400 ppm about 2016."

Gimli & Legolas

This solar fellowship has a long way to go before it reaches the climax seen in "The Return of the King." But consider this: The industry has quite a few proponents who are true believers.

These, who I liken to Gimli the dwarf and Legolas the elf, boast immeasurable talent. Consider, for instance in the movie version of "The Lord of the Rings: The Two Towers" when the two start counting off their kills at Helm's Deep, courtesy imdb.com.

Gimli: Legolas! Two already!
Legolas: I'm on seventeen!
Gimli: Huh? I'll have no pointy-ear outscoring me! [kills another one]
Legolas: [shoots two more arrows] Nineteen!

Soon others of the fellowship will begin listing not their kills but their successes. Jobs will follow.

Heat and time take toll on solar panel performance

Solar arrays at NREL.
The widely held belief of solar systems is that once the initial cost is paid off, the rest is gravy.

Or more specifically, that the power harvested from the sun is free for those who own their systems. And that's true.

However, there's an important detail to consider, especially if the cost of materials and labor are financed over a long period.

"Numerous studies have shown that degradation rates for silicon modules are typically less than 1 percent per year," says analysis from the National Renewable Energy Laboratory in Golden, Colo.

That means power output diminishes minutely each year and could be significantly less for a system once the up-front costs are paid off after financing. That could mean a photovoltaic solar array produces 40 percent less power than the day it was installed once a 40-year loan is paid. A highly technical NREL study says declines could actually be less, ranging from .5 percent to .7 percent.

Of course degradation and performance rates depends on multiple factors, with some being solar intensity and temperature. Series resistance poses another interesting factor as does the system performing only as well as its worst cell. But that can be dealt with by connecting the panels in parallel or using other technical means.

On an NREL map of the United States outlining solar intensity, California's San Joaquin Valley sits in one of the optimal places. The region is sunny.

But with sun comes high temperatures, which also decrease electrical output somewhat. And that's something to consider in the Valley where many communities have more than 40 days of the year hotter than 100 degrees.

The reason for the heat-related performance decline has to do with conductivity, reducing the magnitude of the electric field and lowering voltage, according to solarpower2day.net. "It should be noted that a higher temperature increases the mobility of electrons, which causes the flow of current to increase slightly," the site says. "This increase is however minor and insignificant compared to the decrease in voltage."

Simply put, "the solar radiation which produces solar electricity carries heat with it that will cause the components of your photovoltaic solar panel to become altered and less able to capture sunlight effectively," says solarpanel-direct.com.

NREL has an outdoor test facility that's been operating about a decade testing all sorts of solar panels. As time marches on, more will be written about performance, maintenance and optimizing crystalline photovoltaic systems to extend their lifetimes.

I started looking into this concept after a colleague of mine who works with one of the counties I contract with mentioned solar performance issues. He said the county is likely to continue to pursue development of a significant solar project, but that it is also looking into other methods of boosting its clean energy footprint.

Net-zero construction gains ground in U.S.

Apollo 11 touched down on the Sea of Tranquility with the world watching.

The date was July 20, 1969.

"Houston, Tranquility Base here. The Eagle has landed," the spacecraft announced. Some hours later Apollo 11 astronaut Neil Armstrong took man's first steps on the Moon followed closely by fellow spaceman Buzz Aldrin.

Their footprints at Tranquility Base likely remain, a small sign of a massive accomplishment.

NASA's back in the historic footprint game again but in an entirely different way. The space agency, now somewhat redirected and fiscally leaner with the closure of the Space Shuttle program, has been constructing a facility that takes inspiration for its name from Tranquility Base and seeks to be a landmark in another sense, leaving as little footprint as possible.

Here on Earth

Sustainability Base, at Ames Research Center in Moffett Field, Calif., has been dubbed NASA's latest mission on Earth. The facility has received LEED platinum certification, the highest level of Leadership in Energy and Environmental Design rating by the U.S. Green Building Council. Its design incorporates natural lighting, shading and fresh air. The interior boasts non-toxic materials and is, according to NASA, "a living prototype for buildings of the future."

The net-zero movement -- designing and building structures to make as little impact on the environment as possible -- is gaining steam, albeit slowly.

Commercial and residential buildings consume about 40 percent of all energy in the United States and about 70 percent of all electricity, according to the U.S. Energy Information Administration. And electricity consumption in the commercial building sector is expected to increase another 50 percent by 2025.

The net-zero or zero-energy building concept means commercial or residential buildings meet all their energy requirements from low-cost, locally available, nonpolluting, renewable sources, according to "Zero Energy Buildings: A Critical Look at the Definition," a 2006 study by the National Renewable Energy Laboratory. "At the strictest level, a ZEB generates enough renewable energy on site to equal or exceed its annual energy use," the study says.

Lunar design influence

Sustainability Base, which is shaped like two side-by-side crescents, gets its power from solar panels, wind energy and fuel cells. It's also chock full of other technologies that make it "capable of anticipating and reacting to changes in sunlight, temperature, wind and occupancy," officials say.

“What makes our building different than the other NASA LEED buildings is that preliminary data are already showing a net-energy positive profile. The building site contributes more energy to the grid than it receives from the grid," says Steven Zornetzer, associate center director for research at Ames, in a description of the base on Ames' website.

Because it also incorporates repurposed NASA aerospace technologies to optimize building performance, Sustainability Base's features cooler statistics than other net-zero buildings. For instance, it uses computational fluid dynamics to simulate environmental flows in and outside the building. This can mean air flows such as wind outside and air flow inside. The building's electronic systems calculate this information and incorporate the data into the heating and cooling systems, saving money in conventional heating and cooling.

Movement expands

Many efforts are under way to reduce production of greenhouse gases from the building sector. Retrofits of existing buildings, such as the iconic Empire State Building, have gained recognition, mostly because the energy-saving upgrades pay for themselves relatively quickly.

Measures are under way in a number of areas. They include sustainability policies from some of the largest publicly traded U.S. companies, efforts by states to increase efficiency through building codes (California's new rules took effect in 2011), programs by the U.S. Department of Energy to fund energy efficiency retrofits in municipal government buildings across the country and the whole house and passive house movements to increase efficiency in residential and commercial buildings.

The U.S. Department of Energy is seeking to develop the technology and a knowledge base for cost-effective zero-energy commercial buildings by 2025. The National Renewable Energy Laboratory already has created a classification system for net-zero energy buildings to aid in the standardization process. NREL's Research Support Facility on its Golden, Colo. campus also was certified LEED platinum and uses 50 percent less energy than if built simply to code. It's massive, too: 360,000 square feet.

Passive house

There's also the passive house movement gaining followers in this country. The practice is reaching quite a fervor in Europe. A house at the Cleveland Museum of Natural History designed with no furnace has been completed and is already catching attention. The residence, which uses passive house design and technology, cuts its greenhouse gas footprint and utility costs to the quick. SmartHome Cleveland received a national attention. One story said: "Because the house is so well insulated, it can hold heat from sunshine, body heat, lights and appliances."

The idea behind passive houses is that they use 90 percent less energy than a conventionally outfitted home of the same size. This also could apply to commercial buildings, but most information I've seen seems to keep this trend firmly entrenched in residential construction, at least in this country.

Passive House Institute U.S. defines the concept this way: It's a "very well-insulated, virtually air-tight building that is primarily heated by passive solar gain and by internal gains from people, electrical equipment, etc. Energy losses are minimized. Any remaining heat demand is provided by an extremely small source."

The push is to carbon neutrality.

The Passive House Institute says in the past decade about 15,000 buildings, mostly in Europe, have been designed and built or remodeled to passive house specifications. It's a small number but could gain significant influence as others see the lifetime benefits and reduced operating expenses -- not to mention the ecological rewards.
