Evolving tactics, local fracking, communist solar panels and fatalistic gimmickry: a Smogtown stew

Thursday, April 19th, 2012

  

* When it comes to major California solar projects, these are not your parents’ environmental watchdogs anymore. From outside agitators to inside-the-system players, the green world is shifting, or shrinking. From the L.A. Times:

“April Sall gazed out at the Mojave Desert flashing past the car window and unreeled a story of frustration and backroom dealings … “We got dragged into this because the big groups were standing on the sidelines and we were watching this big conservation legacy practically go under a bulldozer,” said Sall, the (Wildlands Conservancy) director. “We said, ‘We can’t be silent anymore.’ ” Similar stories can be heard across the desert Southwest. Small environmental groups are fighting utility-scale solar projects without the support of what they refer to as “Gang Green,” the nation’s big environmental players. Local activists accuse the Sierra Club, the Natural Resources Defense Council, Defenders of Wildlife, the Wilderness Society and other venerable environmental groups of acquiescing to the industrialization of the desert because they believe large-scale solar power is essential to slowing climate change …”

* Hydraulic fracturing is greatly understated here in California, according to the Times:

“State regulators say existing environmental laws protect the state’s drinking water but acknowledge they have little information about the scale or practice of fracking in California, the fourth-largest oil producing state in the nation. That has created mounting anxiety in communities from Culver City to Monterey, where residents are slowly discovering the practice has gone on for years, sometimes in densely populated areas. “The communities have been left on their own to figure this out,” said Lark Galloway-Gilliam, executive director of Community Health Councils, a health advocacy group that sued a Texas oil company and Los Angeles County over oil extraction near Baldwin Hills. “We are looking to our regulatory agencies to protect us, and they are scratching their heads and turning a blind eye …”

The Obama Administration isn’t ignoring the potential air pollution effects of fracking. It’s enacted rules … that will be applied post-election in a few years. MSNBC article.

* Shot across the bow in a looming, green-energy trade war or political theater designed for domestic consumption. You decide. From the New York Times:

“In a significant decision involving one of the world’s most sought-after industries, the U.S. is gearing up to impose duties on imports of Chinese solar panels after finding evidence that China’s government provided illegal subsidies to its export manufacturers. In a preliminary finding released Tuesday, the Commerce Department said it would start levying duties ranging from 2.9% to 4.73% on Chinese imports of solar panels, as well as panels made in other countries that have Chinese-made solar cells …”

* In case you missed the nostaligic, KCET article about “Smog in a Can” that yours truly appeared in, read on:

“ … In 1957 the “Smog in a Can” was introduced by Hollywood actor Carleton Young, best known for his line from the movie The Man Who Shot Liberty Valance, “This is the West sir. When the legend becomes fact, print the legend.” Establishing the Los Angeles Smog Corporation, Young and associate Hal Tamblin set about canning smog in colorfully designed labels for mass distribution. According to the label: “Genuine Los Angeles Smog. This is the smog used by famous Hollywood stars. Contains hydrocarbons, nitrogen oxides, sulfer dioxide, organic oxides, aldehydes, formaldehydes. “Made in Los Angeles by Angels. To insure freshness and purity keep container tightly sealed. Beware of imitations! Accept none but the pure Los Angeles Smog. “No pollutants or irritants removed. Packed for Los Angeles Smog Corp,, Los Angeles 28, California …”

Of course, you don’t a story to learn about the sociological despair bottled up in those cans. You can just read our book, Smogtown: the Lung-Burning History of Pollution in Los Angeles. What’s a gimmick like packaged air pollution without the context, after all?

 

 

 

April news-bite showers

Unused Ferris wheel near the abandoned Chernboyl nuclear power plant in Ukraine

* It’s official! California must generate one third of its power from alternative sources by 2020. Notice, in this L.A. Times post, that our acceleration into green power may help California reclaim its lofty perch as environmental lodestar. Wait, there’s truth in them there words.

“… The new law, known as a renewable portfolio standard, is the most aggressive of any state. Several attempts to introduce a federal version have stalled in a divided and preoccupied Congress. California had previously required investor-owned utilities such as Southern California Edison, Pacific Gas & Electric and San Diego Gas & Electric to generate 20% of their electricity from clean sources by 2010, with a three-year grace period. The law signed Tuesday will also apply to municipal utilities such as the Los Angeles Department of Water and Power and the Sacramento Municipal Utility District, which manage about a quarter of the state’s electricity load. Energy activists hope the mandate will lead to even more ambitious requirements. “California can power itself entirely on clean energy resources,” said Bernadette Del Chiaro, clean energy advocate with Environment California. “Mandating that the state generate a third of its electricity from renewable energy is a big down payment toward that ultimate goal …”

* And, yet, you want to qualify exuberance for wind energy retaking other alternatives before the Ice Cap re-freezes. Turbines are not having the best year, and you can wager whether it’s cost skepticism, declining subsidies or something to do with oil prices and/or NIMBYism.

Also from the L.A. Times:  “The 5,116 megawatts of wind power installed in the U.S. in 2010 was just half the amount put in during the record year before, but the industry still grew 15%, according to an annual report from the American Wind Energy Assn. To some, the trade group’s data illustrate a young industry’s resiliency amid hostile economics and inconsistent government regulations and incentives. But to others, it’s a worrisome harbinger that wind, which has boomed at an average of 35% each year for the last five, might be headed for a slowdown. The 35,600 wind turbines in the ground nationwide can now produce 40,181 megawatts – enough to supply electricity to 10 million homes, according to the report. That’s 2.3% of all the electricity generated around the country, compared to roughly 2% from solar, geothermal and biomass sources …”

* In what may be the most under-played local enviro news, California’s landmark greenhouse gas cap and trade is expanding into the Great North. Good grief, I say.

“California officials announced Tuesday that the state will expand its newly adopted carbon-trading program to three Canadian provinces, creating the largest regional cap-and-trade system in North America. California will be joined by British Columbia, Quebec and Ontario in a cap-and-trade program aimed at limiting planet-heating greenhouse gases from industrial plants and transportation fuel, and that allows companies to buy and sell emissions allowances among themselves to cut their costs. The Western Climate Initiative, launched by former Gov. Arnold Schwarzenegger, was originally designed in 2008 to engage seven Western states and four Canadian provinces in a trading program. That program, it was hoped, would eventually fold into a broader federal cap-and-trade system to be enacted by Congress. But since then, support for curbing global-warming emissions has ebbed, and the economic downturn has cut into business profits. Federal cap-and-trade legislation was passed by the House in 2009 but stalled in the Senate. Arizona, New Mexico Washington, Oregon, Utah and Montana had signed on to join the initiative but have pulled out of the trading plan …”

Now, the things people do without considering their consequences.

* Does the word carcinogenic matter to energy engineers? It should, but it didn’t as much as it should. Link.

“Millions of gallons of potentially hazardous chemicals and known carcinogens were injected into wells by leading oil and gas service companies from 2005 to 2009, a report by three House Democrats said Saturday. The report said 29 of the chemicals injected were known or suspected human carcinogens. They either were regulated under the Safe Drinking Water Act as risks to human health or listed as hazardous air pollutants under the Clean Air Act … The chemicals are injected during hydraulic fracturing, a process used in combination with horizontal drilling to allow access to natural gas reserves previously considered uneconomical. The growing use of hydraulic fracturing has allowed natural gas production in the United States to reach levels not achieved since the early 1970s. However, the process requires large quantities of water and fluids, injected underground at high volumes and pressure. The composition of these fluids ranges from a simple mixture of water and sand to more complex mixtures with chemical additives … The report said that from 2005 to 2009, the following states had at least 100,000 gallons of hydraulic fracturing fluids containing a carcinogen injected underground: Texas, Colorado, Oklahoma, Louisiana, Wyoming, North Dakota, New Mexico, Montana and Utah. States with 100,000 gallons or more of fluids containing a regulated chemical under the Safe Drinking Water Act were: Texas, New Mexico, Colorado, Oklahoma, Mississippi and North Dakota …”

* Japanese nuclear situation got you down? Well, you can only sign up for a tour of Chernboyl if you’re headed toward the Ukraine and have an appetite for tragedy and history, and are confident about your health. Story.

“For the visitor, Chernobyl makes heavy demands on the imagination — much of what’s important can be seen only in the mind’s eye. From the outside, the building where a reactor blew up April 26, 1986, in the world’s worst nuclear disaster mostly looks like an ordinary, dull industrial building. Only an odd addition supported by buttresses — the sarcophagus covering the reactor — hints that anything unusual happened here. The imagination struggles, too, to repopulate nearby Pripyat with the 50,000 people who lived there. Once a busy town built especially for the plant’s workers, it’s now a silent husk of abandoned apartment towers and scrubby brush slowly overtaking the main square. And inevitably, the visitor tries to picture the radioactive contamination that’s everywhere in the 19-mile area around the plant. The dosimeter clipped to a visitor’s clothes and occasional meters around the site are the only visual clues, flashing numbers that are mostly meaningless to the layman …”

From China to Chinatown: selective retention roundup

Monday, March 7th, 2011

* China is supposedly changing its stripes, from the dark red of capitalistic communism to some yet to be determined shade of green. The world’s fastest growing economy is on an energy conservation kick. Hard to believe, but here’s the New York Times story (color us skeptical): “… Bejing’s emphasis on saving energy reflects concerns about national security and the effects of high fuel costs on inflation, China’s export competitiveness and the country’s pollution problems. Any energy policy moves by Beijing hold global implications, given that China is the world’s biggest consumer of energy and largest emitter of greenhouse gases. And even the new efficiency goals assume that China’s overall energy consumption will grow, to meet the needs of the nation’s 1.3 billion people and its rapidly expanding economy …”

* Not depressed enough? Read up on a little apocalyptic scriptline called “potential mass extinction” from the destruction of endangered species. USA Today story tidbit: “… The IUCN lists 18,351 species on its “Red List of Threatened Species,” considered the global standard for the conservation status of animal and plant species. All are at risk based on current and projected habitat loss or destruction due to human encroachment and climate change. Of those, 1,940 are listed as critically endangered, meaning the species’ numbers have decreased, or will decrease, by 80% within three generations …”

* The Southern California Physician Magazine, which is associated with the venerable Los Angeles County Medical Association, has a long and worthwhile story about smog and health in its April edition. It begins with the lead anecdote from our book, and examines the grim air-pollution health realities, such as we know them. There’s also an extremely informative sidebar about the different sorts of emissions we face here in the basin. From the article: “… The most telling new study, however, is one released just this year from the RAND Corporation. Entitled “The Impact of Air Quality on Hospital Spending,” the study found that in failing to meet federal air quality standards over the years 2005-2007, California incurred an estimated 29,808 preventable hospital admissions and emergency room visits. Even more daunting in this era of escalating health care costs, the authors—John A. Romley, Andrew Hackbarth, and Dana P. Goldman—found that the additional hospital care cost health care purchasers and insurers $193.2 million. Medicare alone spent $103.6 million on air pollution-related hospital care during the course of the study (see “Air Pollution–Related Hospital Events and Charges”) …”

Earth, wind and wire: Going beyond solar panels

Wednesday, February 10th, 2010

Here’s a look at three technologies that California residents are using to cut their energy bills and turn their homes into clean, mini-power plants.

February 7, 2010

By CHIP JACOBS

Note to readers: the following story is a longer, slightly different version of the article that appeared in the Los Angeles Times and other outlets on February 5, 2010. To see that version, click here.

Not long ago, most Californians harvesting green energy at home had pretty much one way to turn: toward their eaves. Rooftop solar panels might’ve resembled giant aviator-sunglasses, with a typical setup costing as much as a luxury car, but they at least delivered power-bill savings without anxiety. Trying to capture rustling winds or subterranean heat or even streamside hydro-electricity sounded as farfetched as it did impractical, and never found consumer traction.

Well, chalk another one up for the green revolution.

Today, with more user-friendly technology on the market and meaty taxpayer-subsidies available to begin popularizing the concept, the era of limited choices is fading. Homeowners out to shrink their reliance on the local utility grid and live greener without opting for standard solar-cells can now do so, depending on where they reside and their tenacity to stick with it.

Experts believe converging trends makes it an idea worth bouncing around. As energy demands continue to tick upwards and governments crack down further on greenhouse gases, everyone – including consumers who previously shrugged off home-generation as a quixotic extravagance — will likely pay more for their electricity and natural gas.

New power plants are just prohibitively expensive to build. And no one knows when the next energy crisis will strike.

“Renewable energy produced at home shouldn’t just be for the granola-eating, Birkenstock-wearing people,” said Angelina Galiteva, chairwoman of the non-profit World Council for Renewable Energy. “It should be for everyone.”

But will more than a hardy band of believers really commit to churning out kilowatts in their own backyards and communal grounds, when just one of 154 California single-family homeowners right now even run solar cells? Will the temptation to lock down energy costs, or the desire for more self sufficiency, catch on in the forward-looking West Coast as it has throughout Europe?

Check back in 2030 for concrete answers. For now, take a look what at some are already doing.

SMALL WIND

People driving along gusty interstates near such places as Palm Springs are accustomed to seeing commercial wind farms, where turbines as high as buildings spin lazily against a blue sky. These days, a modest but growing number of individuals are trying that technology inside their own fence-lines.

Roughly 10,500 small turbines were sold to homes, farms and businesses nationwide in 2008, according to the American Wind Energy Assoc. While the numbers aren’t in yet for 2009, demand remained strong in spite of the Great Recession, said Elizabeth Salerno, the association’s director of data and analysis. A survey of small-turbine manufacturers has projected a 30-fold increase in the U.S. market by 2013.

Locally, some of the growth is emanating from companies eager to contain their electricity tabs. In Palmdale, for instance, city officials have cleared the way for businesses to install wind turbines up to 60-fee-high to crank out their own clean power. Among them is Wal-Mart, which has a 17-turbine project planned for its Sam’s Club outlet in Palmdale.

Potential wise, though, the largest new pool of converts may be individuals such as Ernest Ramirez. He and his wife live in Oak Hills, an unincorporated, blustery section of western San Bernardino County dotted with spacious homes on multi-acre lots. They inherited their wind turbine when they bought their 3,250-square-foot property equipped with a pool and hot tub in 2003.

Ernest Ramirez can’t imagine life without out it now.

Perched on a slender tower about 80-feet high, the turbine has three, 10-foot-long blades that whip often enough to keep his power bills from Southern California Edison at about $100 a month, or roughly a quarter of what he calculates he’d fork out otherwise.

Gusts are so fierce in this part of the Cajon Pass that they have been known to snap trees and jackknife semi-trucks. But Ramirez welcomes a bad hair day. His 10-kilowatt device, which initially struck him as a hovering insect, not only is a money saver. It salves his environmental conscience.

“When I get out of my car and it’s blowing 35-mph and I have to stay inside the house, at least I know I’m saving money,” said Ramirez, a 46-year-old grant writer. “Wind is such a precious resource.”

Ramirez said he can count seven neighbors with their own wind turbines. When the blades on his turn fiercely, they produce a droan that Ramirez compares to a helicopter takeoff. All things considered, it’s a racket he’s happy to have.

Still, what works in windblown San Bernardino County won’t necessarily fit everywhere.

To make economic sense, a homeowner considering a turbine should live in an area where 10-mph winds are frequent, and be paying at least 10-cents a kilowatt hour for electricity, according to the wind association. Permitting is also a challenge in many communities; some neighbors consider the spinning contraptions as noisy and eyesores and even a threat to birds.

The technology certainly isn’t cheap, running about $3,000 to $6,000 per kilowatt installed or roughly $30,000 for an average system, experts say.

Sweeteners are being dangled to cushion some of that sticker shock. Homeowners can get a hefty rebate from the state of California – as much as $12,500 for a typical 5-kilowatt setup. They’re also eligible for a 30-percent Investment Tax Credit from the federal government.

GEOTHERMAL

Everybody knows that solar panels and wind turbines are rock stars of today’s renewable energy world. Fewer might suspect that one of the more intriguing contenders to reduce high utility bills cooks right under our feet.

Geothermal heat pumps, which have been around since World War II, consume 25-perent to 50-percent less electricity than conventional systems, according to the U.S. Department of Energy. Their magic comes from the physics of heat-exchange and vapor compression.

First, pipes are buried, sometimes hundreds of feet down, and formed into a loop. During winter, a refrigerant-type fluid circulating through the loop grabs the heat and transfers it into a structure’s air-handler. When air conditioning is needed in the summer, the process operates much like your refrigerator: the pump draws heat from the home’s interior and dumps it back into the Earth.

Geothermal heat pumps are cousins of regular heat pumps, which draw in hot air from outside. The difference is that geothermal is more efficient because soil temperatures, even just a few feet underground, remain fairly stable year round. Geothermal systems also have few moving parts, so they’re quiet and durable. They can be adapted to provide a home’s hot water.

Dennis Bushnell, a NASA scientist who studies renewable fuels, said that geothermal heat pumps are relied on by a fair number of homeowners and others from Virginia to the Northeastern states. People who reside in warmer Sunbelt states could especially benefit from them, he said, because the loop works best when the temperature stays above 30-degrees.

The equipment is “not exotic at all,” said Langley. “You can go on the web and buy one today.”

Now for the bad news: upfront costs are painful, sometimes twice as much as conventional heating and cooling units.

If your wallet can withstand that initial blast, one satisfied customer says the quick payback time and minimal maintenance expenses make it worthwhile.

California’s electricity crisis motivated John Sergneri to install a geothermal heat pump on his 1,280-foot tract-style home in Petaluma. It cost $40,000, approximately $15,000 more than a traditional grid-dependent system. Still, it has slashed his utility bills dramatically.

Sergneri, an information technologist, is currently renting the house while he works in Switzerland. When he returns stateside, he said he plans to install solar panels to further trim his power costs, because the ground pump and associated machinery, like many renewable systems, requires some electricity to operate.

It’s all part of what he terms a low-cost, eco-friendly “retirement plan.” Sergneri, 58, jokes it will yield a better return than his tattered 401-K.

“My goal is to be as independent as possible,” he said. “I’ve always dreamed of getting as far from the grid as possible.”

Though California isn’t offering rebates for ground heat pumps, a 30-percent federal tax credit is available.

SOLAR HOT WATER

California leads the nation in rooftop solar panels despite the fact that only about 50,000 single-family homes out of an estimated 7.7-million statewide have deployed them. (In the city of Los Angeles, a measly 1,627 homes have solar hookups with the Department of Water and Power.)

A simpler, less expensive path to convert sunrays to electricity is just beginning to catch on with solar water heaters. Officials hope two sets of incentives will pluck them out of obscurity.

Last month, the California Public Utilities Commission approved a $350-million rebate program to coax homeowners to replace their old energy-sucking units with more efficient solar-fired systems. Residential utility customers can get as much as $1,875 for swapping out their natural gas systems and $1,250 for ditching their electrically-heated tanks. The rebates phase out at the end of 2017 — or when the ratepayer-subsidized funds dry up.

Buyers can also qualify for a 30-percent renewable energy tax credit for a new solar water heater from Uncle Sam.

All told, that could amount to as much as a 55-percent subsidy for equipment that normally costs between $6,000 and $8,000, contingent on a home’s size and energy usage.

Here’s the downside: to qualify for a state rebate, homeowners have to be customers of Southern California Edison, the Southern California Gas Co., Pacific Gas & Electric or San Diego Gas & Electric.

Heating water represents the third-largest energy expense for most households, according the Department of Energy. If California’s solar water heater initiative succeeds, 585-million therms of natural gas– the equivalent of 200,000 solar units – and 150-megawatts of electricity will have been replaced with clean power, the utilities commission says.

These systems are already popular in Israel, China, Spain and other countries. Beginning this year, Hawaii is mandating that all new homes be equipped with solar hot water heaters.

“Solar water heaters are the low hanging fruit,” said Katrina Phruksukarn, solar water heating program manager with the California Center for Sustainable Energy. “They may not be as cheap as putting in a high-efficiency light bulb, but they’re about as cost effective as you’re going to get.”

Technologies vary by manufacturer. One common arrangement involves linking a storage tank to a rooftop solar array. Heat collected by those panels is used to warm up copper tubes filled with water contained just beneath dark, heat absorbing collectors. Those collectors raise the temperature of the water, which from there is pumped down and stored in a well-insulated storage tank. Back-up gas or electrical heating kicks in if the temperature falls below a certain threshold.

Steve Glenn, whose company LivingHomes, designs eco-friendly modular dwellings, has a system in his home that employs solar tubes filled with special, low-boiling point oil. When sunrays strike the tubes, they produce steam that rises and transfers some of its heat to water, which is warmed and stored in an ordinary-looking 60-gallon tank. The water is then delivered to showers and sinks. Heat radiating from the system’s piping also keeps the floors toasty.

Glenn said the solar hot water heater, photovoltaic panels and other energy-miserly features in his Santa Montica home have reduced is electric bill to the cost of a nice lunch: about $15 to $20 a month.

“I don’t have to even think about it” Glenn, 45, said. “The hot water feels like hot water. I’m not aware its sun baked, and not natural gas baked.”

BIOMASS

Another home-based renewable is an update to 19th-century prairie life. Furnaces and stoves that burn wood pellets made from sawdust, bark and other industrial byproducts, as well as corn, dried cherry pits and other organic materials are now on the market. Unlike traditional cord wood, these fuels cough out relatively little ash, soot and other harmful emissions.

Depending on the house, the biomass burners can supplement or replace a structure’s conventional heating system.

Like many renewable energy concepts, though, they are not for fence sitters. A stove or furnace, which resembles a stand-alone, glass-enclosed fireplace, can run $5,000 or more with installation. The fuels themselves also aren’t necessarily cheaper than natural gas or oil heat. A typical system eats up to three tons of them yearly.

At Floyd S. Lee Fireplace & BBQ in Pasadena, they’re just starting to sell a small fireplace for $900 that burns a clear-liquid biofuel requiring no venting. Since the unit doesn’t generate bounds of heat, it’s mainly decorative, said salesman Tom Broderick. Actual pellet-burning fireplaces have promise, he added, once retail stores can more easily secure pellets from suppliers.

“But they’re trying new things all the time,” he said. “Nobody is sticking with the old.”

As with ground heat pumps, there is no state rebate available for biofuels burners. There is a $1,500 Energy Star rebate that expires Dec. 31.

Coming down the pike is a household “bio-reactor” just being introduced in England, said NASA scientist Bushnell. It converts kitchen scraps, yard waste and sewage into electrical juice.

“All these (ideas) were possible ten years ago and are now more possible because of the pace of technologies,” said Bushnell, who works out of NASA’s Langley, VA. research-center. “Once people learn about the realities of the energy-price situation, they’ll know they have to consider adjusting how they live, including considering renewables.”

SIDEBAR STORY AND LINKS

Three years ago, the state rolled out its Go Solar California! program to dramatically boost adoption of solar power and fortify an industry devoted to it. The $3.3-billion, ratepayer-financed effort has a goal of adding 3,000 megawatts of grid-connected solar by 2016.

If that objective is met, it could spare California from having to build six new gas-fired power plants, which generate about 500-megawatts per year. The average home consumes about 10,000-kilowatts annually.

The Public Utilities Commission as part of this effort has earmarked $2.2-billlion program in rebates to encourage homeowners, businesses and non-profit agencies to install solar-photovoltaic roof panels and solar water heaters. They’re only available for customers of Southern California Edison, Pacific Gas and Electric and San Diego Gas and Electric.

So far, about 257 megawatts of new solar have come on line, the bulk of that in industry. If that doesn’t sound impressive, especially compared to Europe, it represents more than three times what was installed in the 1980s and 1990s combined. And despite the low-consumer usage, California accounts for about two-thirds of the nation’s entire installed-solar.

Officials are hoping that by the time the incentives are exhausted, generating power at home will be considered a cost-savings staple, not an extravagance. Until then, consumers’ bitterness from the 2000-2001 electricity crises and more recent recession may help forge a spirit of productive independence.

“You saw faith being lost,” said Ben Airth, who works with the Center for Sustainable Energy, a non-profit involved in California’s solar campaign. “America has been brought up on the idea of plugging into the grid through a utility and now people are seeing for themselves what they can do about producing their own electricity.”
