Reporter's Notes: The Godfather of Green

February 12th, 2010 by Andrea Kissack

Don’t forget to turn off the lights next time you leave a room. You’ll make an 83-year-old physicist, with a passion for saving kilowatts, very happy

Do you know what the biggest energy drain is on your house? Well, if you don’t have a hot tub, it’s heating and cooling your house. My head is swimming with energy efficiency facts after producing this week’s QUEST radio piece on efficiency guru Art Rosenfeld. Rosenfeld is retiring, stepping down after two terms on the California Energy Commission. The guy has spent the past thirty five years fighting for us, California’s energy consumers. While electricity consumption has risen, sharply, in the rest of the country, California’s electricity use, per capita, has remained nearly flat since the early 1970’s. It is not that we are any less addicted to our flat screen TVs and personal computers, it’s that the state, thanks in large part to Rosenfeld’s dogged persistence, has put in place some of the strictest energy standards in the world. His passion for saving killowatts has saved billions on utility bills and improved air quality.

As it goes with people who are driven by a cause, the 83-year-old physicist is not really retiring. Rosenfeld will be returning to Lawrence Berkeley National Labs a few days a week to continue his research on low reflective white roof tops. His work has shown white roofs can cut electricity use by 15-percent by reducing the need for air conditioning and they combat climate change at the same time. White roofs are now mandatory on commercial buildings in California, thanks, in part, to Rosenfeld. Check out our radio story on cool roofs.

And by the way, don’t forget to turn off the lights next time you leave a room. You’ll make an 83-year-old physicist, with a passion for saving kilowatts, very happy.

Reporter's Notes: Solar Thieves

December 23rd, 2009 by Andrea Kissack

Napa Valley is a hot spot for solar panel thieves, but the Sheriff's office is on the case.

The economy may be in the tank but business is booming for solar security companies. A rash of solar panel thefts in the Napa Valley, and elsewhere, have spawned an entire new industry, solar security systems.

It seems that as prices for scrap metal have fallen, thieves have turned their attention to something else popping up in rural areas, solar panels. With more than 34,000 solar installations in California, the state is also reporting the most thefts. Napa Valley is a hot spot because of all the solar systems that have been installed in the past few years. "It is a rural area and these solar arrays are often ground mounted and tucked away in the back of vineyards, it makes them an easy target", says Napa Sheriff Deputy Jon Thompson. The Sheriff's office has been giving wineries safety tips for securing their panels. After being hit twice, Michael Honig of Honig Winery in Rutherford got wise and installed an alarm system. The third time, the thieves got caught in the act. Three local suspects were apprehended.

It is an environmental CSI case of the first order because no one knows where he panels are actually going. In some southern California solar heists, the stolen panels have turned up for sale on Craigslist. But in northern California, the stolen panels have yet to be found. Deepening the mystery, the panels are not likely valuable for their component parts raising the possibility of a black market for panels. There is a lot of speculation where they are going. Some say marijuana growers in Mendocino County are stealing panels to hide their electricity use. Others believe the panels are going off shore. In addition to security, federal legislation may come to the rescue. Congressman Mike Thompson, who represents the Napa Valley, has included a provision against solar thefts in the Solar Technology Roadmap Act. The bill would create a national registry for solar panel serial numbers to try to ‘short circuit' the crooks.

Reporter's Notes: Saving Our Parks

October 30th, 2009 by Andrea Kissack

Henry Coe State Park won't be experiencing any part-time closures, but it will reduce trash and restroom service and has shuttered a new visitor center off the Pacheco Pass.

So you want to reserve that primo camping spot at your favorite California State Park? You might just have to take your chances. Most state parks are not accepting reservations through spring of 2010. It's part of a series of service cuts to slash millions from the State Parks' budget. Remember back in September when the Governor threatened to close 100 parks to balance the budget? Well, after a giant public outcry, he backed off but he still is requiring California State Parks to cut this year's budget by 14-million dollars. Superintendents from the state's 21 parks have come up with a plan to close that budget gap.

More than half of the state's parks will be scaling back days or hours. The list includes inland campgrounds and day use areas, many state beaches, museums and missions. In addition to reduced hours, trash and restroom service will be cut back at many state parks. I visited Henry Coe State Park in Morgan Hill. Because of it huge acreage (87,000 acres) and back country wilderness, Coe won't be experiencing any part-time closures, but it will reduce trash and restroom service and has shuttered a new visitor center off the Pacheco Pass. The park also lost all of its ranger aides. I also took a tour with the Superintendent at Angel Island State Park where they will be closing some restrooms, postponing school field trips and non-emergency repair needs. The situation is not expected to get better right away. The governor has already signed a budget that requires State Parks to cut 22-million dollars next year. California's parks have relied on the state's unpredictable general fund…and that has resulted in a billion dollar maintenance backlog. Park supporters are considering a ballot measure for next year that would impose about a 15-dollar a year vehicle license fee to pay for park operations. Want to hear more?

Reporter's Notes: The Politics of Green Wine

September 4th, 2009 by Andrea Kissack



I often look at the chemical ingredients in what I buy. I shop at farmers markets for organic produce and use green cleaning supplies. So, it caught me off guard when a friend remarked, "you are so aware of what you eat, why aren't you just as curious about what you drink?" Well, we drink organic coffee but not organic wine. I was worried about sacrificing taste and I just didn't think most vineyards were heavily sprayed with pesticides. Then I learned that wine grapes are the second most sprayed crop in the state. This didn't seem like it could be that good for the farm workers, the Earth, or the consumer. Several studies have found trace amounts of pesticides in wine. They may be at extremely low amounts, but what kind of impact could pesticide residues have overtime?

Armed with a new green cause, I set out to find more information about eco-wines. I learned that organic wine is just one type of green wine — there is also wine made with organic grapes. It turns out I had been drinking some of these wines and enjoying them. The thing is, you can't call it "organic wine" if the wine has added sulfites, a naturally occurring compound. Most winemakers add sulfites to help preserve the wine and make it more stable. If a wine is made from organic grapes but contains sulfites, the world "organic" can only be mentioned as part of the ingredient claim on the back of the bottle. No wonder I didn't know I was drinking wine farmed organically.

It turns out northern Sonoma County and Mendocino county are hotbeds for green wine. In the course of reporting this story, I visited several of these wine makers. Bonterra Vineyards, below Ukiah, has been farming organically since 1987 and now farms one of their ranches, McNab, biodynamically. Their red blend is nicely balanced and tastes very good.

Biodynamic is a novel form of organic farming practice with its roots in France. A biodynamic vineyard is a self-sustaining ecosystem — making organic compost, removing chemicals from the soil and farming with the cycles of the Earth.  Biodynamic has its own international certification. (Here is a list of their certified wines). Just up the 101 from Bonterra is Parducci Wine Cellars. This family run company is farming organic grapes and in some cases, biodynamically. Parducci also claims to be one of the most sustainable wineries in the country.

Sustainable is a squishy term. Sustainable wineries may be running off solar power or doing creek restoration to save spawning salmon but they are not necessarily organic and they are not certified. However, the California Sustainable Winegrowing Program is working toward an industry certification. The idea is to raise the entire industry's practices and help vintners make more eco-friendly choices that often include using less chemicals in the vineyards.

Back to sulfites. This ended up being the main reason for the stigma still associated with green wine. Twenty years ago, green wines were uneven and there were not that many choices. Now, several of these eco-wines are winning high points from the industry. Organic wine can only contain naturally occurring sulfites, under 10ppm. Wines farmed organically must keep the added sulfites below 100ppm. Conventional wine can contain sulfites as high as 300ppm. When I was reporting this story, several folks asked me if I was going to explain why they get headaches from red wine. Isn't it the sulfites? Actually, it is not known why some people get headaches from drinking red wine. It could be the histamines. It doesn't look like it's the sulfites. Less than 1% of the population, according to the FDA, is sensitive to sulfites. The reaction is a respiratory one.

Anyway, if you enjoy wine, I encourage you to think beyond red and white but to consider green, too. To find out more, listen to our radio story and check out our links. Also, green wine pioneer, Paul Dolan together with Parducci has created a green wine handbook which is very helpful.

Reporter's notes: Playing with Lead – Part 1

August 7th, 2009 by Andrea Kissack

The paint on this piggy bank tested for lead at 7253 parts per million (ppm); that is 11 times higher than the legal limit for lead paint. By Oanh Ha, Globalization Reporter for The California Report.

Editor's Note: This week we have the first of two special reports on lead.

As a parent, there is a lot to worry about when it comes to the safety of my kids. Lead wasn't high on my list. Lead poisoning in children has dropped significantly in recent decades since the ban on lead-based paint in homes and the phase-out of leaded gasoline. Then came the record toy recalls of 2007, where millions of imported items coated in lead paint and made by household names like Mattel and Fisher Price violated the 30-year-old lead law.

Suddenly, parents, including me, eyed the toys in our homes and on store shelves with suspicion. Extensive research links lead exposure in children to lower IQ scores, neurological and behavioral problems, even anemia.

The toy recalls prompted congress to pass the Consumer Product Safety Improvement Act of 2008.

The Act not only lowers limits for lead and bans certain kinds of phthalates–it makes manufacturers and distributors accountable for products sold to American consumers by requiring items to be certified by third-party labs. But the testing, or certification piece of the Act, was postponed for a year. That raised a lot of questions for me as a reporter and as a parent.

I contacted the Center for Environmental Health, which researches lead, and other toxics, in consumer items and has sued manufacturers and distributors for violating standards.

CEH and KQED were interested in looking at what's sold at discount chains and 99 cent stores because of the history of previous recalls. CEH, through its regular spot testing, also thought that many of the larger retail outlets seem to have improved their process to weed out lead in children's items after the 2007 recalls.

I got some tips from CEH about potentially problematic products to look for. We purchased about 200 items and then CEH did the first round of testing using an X-ray fluorescence (XRF) device. The XRF is a handy tool used by a lot of commercial lead inspectors. It shoots high-energy x-rays at the item and sends back a chemical analysis, including the lead content.

Most items that exceeded the lead limits (600 parts per million) set by the Consumer Product Safety Improvement Act using the XRF device were then sent to a federally-accredited lab, MACS in Hayward, for detailed testing. At the lab, the parts or components that exceeded the lead limits were cut or scraped off and dissolved in an acid solution. Then tests were run to determine the lead content.

View a slide show of several of the items that violate the new lead limits below. We've also put together a list of items that violate the new lead limits, along with the test results.

So how can parents keep leaded toys away from kids? In addition to avoiding vinyl products, stay away from metal jewelry.

If you can, choose natural wood toys instead of painted items, especially if they are in yellow. Check the recall list posted by the Consumer Product Safety Commission. Many companies sell home lead test kits for consumer products. They're not 100-percent reliable and can give false negatives-and false positives too. If you're really concerned about your child's lead level, the best thing to do is to get a blood lead test.

Reporter's Notes: Museum 2.0

July 10th, 2009 by Andrea Kissack



Hard economic times and changing social trends have some museums undergoing a 21st century re-design. The focus is on creating more visitor-centered exhibits using new media tools and more input from the public. Some technology and history museums in the Bay Area are helping to lead the way, as you will hear in our radio piece.

When the public is invited in to help design exhibits, it can create faster turnover and more affordable exhibits. The Tech Museum in San Jose, for example, held a competition in Second Life. The public was asked to design exhibits on the theme of art, music and film. Entries came from as far away as England and China. Winners were awarded five thousand dollars each and asked to translate their designs into a real life gallery space. That exhibit is now on display at the Tech.  According to the Tech's Director, Peter Friess, the exhibit could have taken three years to design. Instead, it took six months. Museum directors are hoping that asking the public to help generate, share and update content will also create more loyalty and drive up ticket sales.

Some people cringe at the idea of asking the public to design museum exhibits. They point to the unlimited number of cat videos on You Tube and ask, "is this really what we want to do to museums?" The museum directors I spoke with say that there is still a role for the curator in this new model, but as more of an educated facilitator than an autocratic, removed taste-setter. Nina Simon, a participatory exhibit designer who writes a blog called Museum 2.0 thinks about this question a lot and has some interesting ideas.

While the participatory, hands-on movement has been around for awhile, these museums are picking up on a cultural shift – and it's not just Bay Area history and technology museums. The Smithsonian American Art Museum was the first to offer an alternate-reality game. The director of the Walters Art Museum in Baltimore thinks the mission of museums may be expanding to include social services. The Brooklyn Museum created a temporary exhibit, "Click," using crowd sourcing and the Museum of Minnesota created a permanent exhibition based on nominations from the public. I wonder what Web 3.0 will bring?

Reporter's Notes: High Tech in the Vineyards

March 27th, 2009 by Andrea Kissack

Wine making is indeed an art form, but it is increasingly becoming more scientific. I knew growing wine grapes requires a lot of attention to detail — there is the terroir, pests and diseases and all those microclimates. But who would have known, driving down Hwy 29, the main thoroughfare through the Napa Valley, that many of those vineyards are totally wired.

In our radio story, we feature the stylishly high tech Vineyard 29 and the Robert Mondavi Winery, but scores of other wineries are using a similar toolbox of technology to help them monitor the soil's water content to grow better grapes. The technology ends up conserving water, too. Remote sensing, ground penetrating radar and satellite technology have helped Mondavi cut back on water use by 30% in recent years.

Winemakers are using some of the same technology that NASA uses to study Mars and engineers use to build hi-rises and freeways. A typical toolbox includes multi-spectral imaging, weather stations, neutron moisture probes, and pressure bombs and there is a plethora of newer technologies in the pipeline. But enough with all the high tech gizmos. How does wine from high tech vines taste? The answer might be found in the success of the winery. Mondavi has won numerous awards over the years and there is a two-year waiting list just to purchase Vineyard 29 wines.

Check out our slide show to see some of these technologies or listen to our radio report on high tech in the vineyards.

Reporter's Notes: Mass Transit Housing Plan

February 13th, 2009 by Andrea Kissack



By Rori Gallagher.

Even in these difficult economic times, California's population continues to grow, and those additional people are going to need a place to live. Recent legislation in California directs city planners to make environmentally responsible choices for new housing. One way to do that is to create transit villages.

The idea is to design housing near a transit station with easy access to retail and commercial space. That way people can drive less if they want to. Some transit villages are easy to identify as pre-planned developments, like the transit village in South San Francisco. Others developed more organically, like the area surrounding the Rockridge Station in Oakland.

As with all new development and redevelopment, there's always a concern about gentrification. Most cities have a requirement that a certain percentage of new units are offered below market rate. But some longtime residents of established communities, like San Mateo, worry about new development changing the character of the community. In order to make transit villages work, designers have to carefully blend new development with the existing community, creating a truly pedestrian-oriented destination. Check out a map of transit-oriented development in California. Also, here are some fun audio walking tours of transit-oriented development projects in the Bay Area.

Reporter's Notes: Building Blocks Go Green

December 19th, 2008 by Andrea Kissack



By reporter Marjorie Sun.

I got interested in this story after hearing Silicon Valley venture capitalist Vinod Khosla speak at a conference this fall in Sausalito. He explained how he decides where to invest in green tech and it was fascinating. He and other top venture capitalists think they can help stop global warming and make a ton of money at the same time. You can listen to Khosla's talk on a webcast and listen to all sorts of entrepreneurs and v.c.'s talk about the latest renewable energy projects.

Khosla says to achieve a huge reduction in greenhouse gas emissions fast, we have to think about solutions that make big cuts in emissions and will be widely adopted. Buying a Prius is fine, he says, but it's really just "fashion." We need solutions that people in India and China will buy, Khosla says. To him, the key issues that guide his investments are cost, scale, and adoption. If a renewable solution isn't cheaper than coal, forget it, he says. Geothermal "is nice, but it doesn't scale."

Same with wind. It's "a great technology, but it's a toy." As for hydrogen fuel, the adoption risk is too high. Again, forget it, he says. The focus should be a war on coal, oil, and the manufacturing of cement and steel, which are huge emitters of carbon dioxide. (He's a major investor in Calera, an alternative cement maker in Silicon Valley.)

One more area for potentially huge gains is to improve energy efficiency, such as lighting. Another legendary venture capital company, Kleiner Perkins, is also racing to develop renewable energy solutions and make a fortune. (Khosla is a former partner there.) Kleiner's efforts were profiled in a cover story in The New York Times Sunday Magazine recently

With the Obama administration, it will be interesting to see what new federal policies– tax, economic and regulatory– will be adopted to accelerate solutions and spur more investment during a double whammy of crises: the economic meltdown and climate change.

Green Sushi

October 24th, 2008 by Andrea Kissack

This sushi is good enough to eat.
Photo credit: Andrea Kissack.If you are a sushi lover, they can make your mouth water just thinking about them, bite sized pieces of Hamachi (yellow tail tuna), Ebi (shrimp), red snapper and Toro (Bluefin tuna) over vinegar sweetened rice. Can’t you just taste the raw fish delicacies right now? But, not so fast, these popular sushi items may not be the best thing you could do for yourself or the sea. They are either over-fished, farmed with aquaculture methods that pollute the ocean, are caught using methods that destroy ocean habitats or they are likely to contain contaminants, such as PCBs and Mercury, that can harm human health.

There is a new trend in town. Sustainable sushi. The Monterey Bay Aquarium, and two other ocean conservation groups (Blue Ocean Institute and Environmental Defense Fund), have come out with new advice for making better sushi choices. Modeled after the Monterey Bay Aquarium’s popular Seafood Watch Pocket Guide, the new sustainable sushi guide helps consumers make informed choices by categorizing seafood into three areas: Green (or best choice), Yellow (or good alternative) and Red (what to avoid). Just what kind of sushi you should avoid may surprise you. Until now, Unagi (bbq eel with avocado), seemed pretty harmless and a good choice for reluctant sushi eaters. Well, Unagi is farmed, freshwater juvenile eel so that definitely gets a red light from the Seafood Watch folks. You can try a sustainable alternative to Unagi at Tataki Sushi Bar in San Francisco. It may be the only restaurant of it’s kind in the country. The owners of the all sustainable sushi restaurant say they don’t want to become a niche as much as they want to influence the rest of the industry to change its’ practices. And with sushi a growing multibillion dollar industry, consumer preferences can have a big impact.

So how do you green your sushi? Try Pacific Halibut, farmed scallop or North American Albacore. Monterey Bay Aquarium biologists consider these among the “best” seafood because they come from abundant, well-managed fisheries or are raised using sustainable aquaculture methods.
