Wellness Wednesday: Reducing Food Waste

I have mentioned waste and recycling in a previous post, but recently came across another article in the Fresno Bee talking specifically about food waste. UC Merced and several other colleges have received praise by the U.S.Environmental Protection Agency for their efforts to reduce food waste and increase awareness on the topic.

Food waste is expensive, crowds landfills, and adds to greenhouse gas emissions.  UC Merced composts cafeteria waste and has switched to recyclable food containers as part of its goal to achieve zero net energy consumption by 2020.


Ways you can help reduce food waste:

  • When eating out, order an appetizer or two, choose from the children’s menu, or share an entrée with a friend. Portion sizes at restaurants are absolutely out of control! This tip not only will help with food waste, but likely the size of your waist. I usually gravitate towards the appetizers on a menu because they just sound better! If you still have leftovers, take them home and enjoy for tomorrow’s lunch or dinner or get creative and incorporate with other ingredients for a whole new meal.
  • Take inventory of your fridge and pantry before grocery shopping. How many times do you come home from the store and struggle to find room in the pantry or refrigerator shelves? Take a cue from those who live in big cities: shop more frequently and only for what you will use for a few days or up to one week. Sure it is a bit more effort but you are more likely to use all of your ingredients before they expire or rot. I like to challenge myself to become more creative in the kitchen by utilizing everything I have to the very last drop, so to speak. Soups and stews are a great way to utilize leftovers and produce that are on their last leg. Overly ripe fruit that has not yet spoiled can be cut up in small bits and then frozen for use in smoothies or frozen yogurt.
  • Similar to the tip above, never grocery shop while hungry! It’s amazing what ends up in your cart when your stomach is growling. It’s likely that these impulse purchases will lead to extra waste/waist.
  • If portion control is an issue for you, eat off of smaller plates/bowls. You are less likely to stuff yourself silly and/or throw the extra bits of food on your plate in the trash.

10 cool advancements in clean energy

The Space Race showed nations can accomplish great things when everyone is committed to a common goal. Increasingly, people are suggesting that same we-can-do-anything attitude be applied to clean energy. In many ways, it's occurring.

Here are 10 things that grabbed my attention in recent days:

1/Solar windows: Much is being written about solar shingles and even solar clothing, but researchers are also studying if windows - think skyscrapers - could double as energy generators. Challenges abound, as this post in environment 360 points out because they have to be clear, but a Maryland company claims to have a way to spray on a see-through solar coating. Researchers and students at UC Merced also are working on something similar here;


2/The smart minds up the road from us at UC Merced designed an innovative low-cost, non-tracking solar thermal collector system that is able to operate with a solar thermal efficiency of 50% at extreme temperatures. Previously, only more complex tracking solar thermal collector systems could achieve this temperature. The system has practical applications in solar heating, cooling, desalination, oil extraction, electricity generation, and food processing, says Ron Durbin, executive director of University of California Advanced Solar Technologies Institute. Here's an ABC 30 story on it;

3/ Speaking of universities and solar cells, the equally smart minds at USC are developing nanocells that could fit on plastic. Think of the possibilities! More here;

4/ Isn't nature great! The humpback whale is influencing windmill blade design. Click here.

5/ Iceland wants to lay an undersea cable to export geothermal to Europe;

6/ A New York company uses on-site wind turbines to meet 60 percent of the power needs of a mammoth manufacturing plant. Gigaom has it - and more here;

7/ Sidewalks that use kinetic energy from footsteps to generate power for nearby appliances. Crazy, but read about it here. Similarly, these trains in Philly can store kinetic energy from braking for further use.



8/  Superman may not be able to change in these booths, but folks will be able to power up their electric vehicle and monitor pollution. Oh, and they can also make a call;

9/ Making good clean power out of bad bad land. Our blog;

10/  The U.S. and U.K. joining forces to develop floating wind power. More here.

These are just a few things that I noted in recent days, but certainly isn't complete. These solar powered bins that text when they're full are pretty cool too. Maybe it's true when people say clean energy is the next industrial revolution.

UC Merced sets the sustainable bar way, way up

The newest campus in the University of California system is quietly becoming a sustainable model and developing a reputation as a center for world-class research.

The University of California, Merced just had its seventh building certified gold by the U.S. Green Building Council’s Leadership in Energy and Environmental Design, or LEED, program.

Its long-range plan, which embraces economic, social and environmental sustainability in campus facilities, was named to the American Institute of Architects' Committee on the Environment Top 10 Green Projects program.

And physics professor Sayantani Ghosh, along with Richard Inman, Georgiy Shcherbatyuk, Dmitri Medvedko and Ajay Gopinathan recently won recogntion of their research in renewable energy in the clean energy press.

Renewable research leader

Zachary Shahan of cleantechnica.com explains the research breakthrough as an effort "to redesign luminescent solar concentrators in order to make them more efficient at sending sunlight to solar cells."

Efficiency is the key to commercial viability in the renewable energy game. Keeping up with lower priced fossil fuels is the ultimate goal. Ghosh explains in Shahan's article that his team tweaked the traditional flat design for concentrators and made them hollow cylinders. Should the technology prove itself in cost and efficiency boosting, many, many more will hear about UC Merced.

The concentrator project is just one of a number of top-notch research programs that involve renewable energy at the San Joaquin Valley institution. Open just since Sept. 5, 2005, UC Merced is the 10th campus in the University of California system and calls itself "the first American research university of the 21st century."

"We’re attempting to set new standards for energy efficiency and environmental stewardship,” says Thomas Lollini, campus architect and an associate vice chancellor, in a statement, referring to the buildings on campus. However, the campus has embraced sustainability on multiple fronts.

Green building movement

The U.S. Green Building Council reports that LEED certified projects are pushing 1.9 billion square feet nationally. The designation was set up in 2000 to provide independent, third-party verification of cost-efficient and energy-saving green buildings.

In the United States, buildings account for about 36 percent of total energy use and 65 percent of electricity consumption, 30 percent of greenhouse gas emissions, 30 percent of raw materials use, 30 percent of waste output (136 million tons annually) and 12 percent of potable water consumption.

Any dent in that is a big deal.

Effort already a decade old

Richard Cummings, principal planner at UC Merced, says the green building movement on his campus began in 2002, when founding Chancellor Carol Tomlinson-Keasey established the goal of the campus meeting LEED silver for all buildings. What ended up happening is that all buildings but one ended up LEED gold, he says.

"As a result, our new 2009 master plan requires that all new buildings meet LEED Gold at a minimum and that the campus be zero net energy, zero waste and zero net emissions by 2020," Cummings says, adding that the campus also uses an internal, more-rigorous-than-LEED, benchmarking approach to energy efficient buildings.

The buildings certified LEED gold on the campus include the Leo and Dottie Kolligian Library, Classroom Office Building, Science and Engineering 1, Sierra Terraces Dormitory, Joseph Gallo Recreation Center and the Central Plant. The Valley Terraces Dormitory is certified LEED silver.

Going for gold

Buildings expected to achieve gold certification include the Dining Expansion, the Early Childhood Education Center, Housing 3 and Social Science and Management Building. Building pursuing certification are Housing 4, Student Activity and Athletic Center, Science and Engineering Building 2 and the Student Services Building.

"UC Merced's commitment to LEED Gold combined with its aggressive energy saving design standards enables the campus to reduce energy costs by approximately $1 million per year when compared to typical university buildings in California," Cummings says.

"In addition, UC Merced's state of the art buildings are supplemented by a campus solar array that routinely produces half of campus electricity when the sun is shining and 1/6th of annual electricity needs."

Newest green building

Construction of the Logistical Support/Safety Facility, the seventh building certified gold, featured a number of sustainability-related achievements. About 77 percent of construction waste did not go to landfills but was ground up for reuse by farmers and nurseries.

Water use in the facility was reduced by 48 percent via the installation of waterless or low-flow urinals, lavatories and sinks. And 24 percent of the materials used in construction were made from recycled content.

All of those factors contributed to the high LEED ranking, officials say.

“This is a profound example of taking the long view of the built environment, setting out an early plan, identifying benchmarks, designing and building a campus, seeing if you are meeting your benchmarks, and continuous improvement until hopefully you reach the goals of zero energy and zero waste for 10,000 students in 2020,” wrote one juror who contributed to the American Institute of Architects' Committee on the Environment ruling that put the campus on its Top 10 list.

“It’s an astonishing ambition, and they are on track.”

California On Way To Becoming Solar State?



One of my former newspaper colleagues referred in this post to "The great Central Valley solar rush," but it turns out that might be too regional. California could well become the great Solar State.

The number of proposed solar projects exceeds what is required to meet California's ambitious 33 percent renewables by 2020 mandate, according to this Reuters story. It's unlikely that all the proposals will be approved, but it is encouraging to the solar energy movement. I wonder if California will exceed the 33 percent mandate and, if so, by how much?

Solar makes sense in California, especially in the San Joaquin Valley and Southern California deserts where the sun shines brightly and land is abundant. There are challenges, however: Some farmers in the Valley fear conflicts with prime ag land, while habitat and other environmental concerns plague some desert projects.

The solar vs farmland issue will be discussed Feb. 6 by planning commissioners in Kings County, where an advisory agency is recommending that solar projects not be placed on land protected under The Williamson Act or on property that is designated "medium priority" or higher. Here is a study document that commissioners will review.

Still, solar is making inroads. Fresno property owners are discovering the power in rooftop solar, and the Valley's farmers are fast adding renewable sources to their operations. Agriculture and water pumping consume about 3.15% of the total power used in PG&E and SCE territories, according to the California Energy Commission, so participation from the farming community is welcome.

I lack the mental bandwidth to understand all the physics involved, but technological advances in solar energy are coming at a breath-taking rate. Costs are decreasing, and it won't be long until solar power reaches parity. Read here about what our friends at UC Merced's fast-emerging solar-energy research center are doing.

With costs falling and Gov. Brown's support, solar could expand in earnest in California, and we'll have more proposals such as this large one for thousands of solar panels in the west side of Fresno County.

Jail Facilities Lock Up Solar Power



My friend half jokingly refers to the inland portion of Central California as "Valley of the Cons" because prisons employ so many people here. The state Department of Corrections is listed as major employers in Madera, Fresno, Kings and Kern counties, according to the state Employment Development Department.

Coalinga, Corcoran and Chowchilla are home to some pretty large correctional facilities. Then there are the smaller county jails. Both kinds of lockups face the same dilemma: shrinking budgets. Maybe Solar Valley can meet Valley of the Cons. Sixty miles to my north is Merced County, where officials thought up a way to slash power bills, contribute to the state's ambitious 33 percent renewables mandate and make a few bucks. They signed a deal with Siemens to put solar panels at a county jail. More on that here.

The idea of using solar energy at prisons isn't new. In 2001, GreenBiz.com wrote about this project in Alameda County, and state officials are planning solar panels at prisons in Delano and Tehachapi, both in Kern County (also Blythe and Lancaster, according to this story ).

The solar array in Merced County will cover 4.5 acres, offset 75 percent of the power usage at the John Latorraca Correctional Facility and Iris Garrett Juvenile Justice Correctional Complex, will lead to an estimated $14 million in energy savings over 25 years and could create $9 million of positive cash flow over the same 25 years. It also will eliminate about 1,000 tons of CO2 emissions when combined with lighting upgrades implemented by Siemens.

The county will receive solar incentives totalling $1.5 million over five years, and is eligible for PG&E's capital improvement rebate.

Powering jails with solar energy is only one way that local governments can slash utility costs. Increasingly, cities and counties are using solar energy to save money at their biggest energy hogs: water treatment plants.

SunPower Corp. has finished deals at water operations in Los Angeles, Riverside and Sacramento counties, according to this article in pv Magazine, but they are hardly isolated cases. Similar connections are in place in Parlier, Tulare and Madera in the San Joaquin Valley. Learn more here.

The San Joaquin Valley, where I sit, is blessed with lots of sun. But that sun also creates triple-digit temperatures in the summer, which leads to high power bills and high energy use. Utilizing the rich solar resource to attack the high power bills makes sense here. That's why officials at UC Merced, which has a top-notch solar research program, unofficially dubbed this region "Solar Valley."

That certainly sounds better than "Valley of the Cons."

Solar Energy Scientists Descend On UC Merced




Blake Ringeisen stood out at a conference where much of the discussion centered around chemistry and physics. The tall, lanky and bearded graduate student researcher at University of California, Davis, provided the real-world perspective of concentrated solar energy when he showed that a simple solar fruit dryer can change the fortunes of farmers in east Africa.

In a region without electricity and refrigeration, Ringeisen's master's thesis, drawings of which were displayed at a solar research symposium at UC Merced, means that farmers who barely scratch out a living in Tanzania can preserve more of their harvest.

Without the dryer, up to 80 percent of their crop goes bad before it can be sold. With it, more tomatoes are dried faster and sold at higher prices, even during the off season, which means more money for farmers in underdeveloped nations.

Ringeisen tested two prototypes. He kept the designs simple - few moving parts, wood frame and polished aluminum surface - so that one or two people could build and move them using materials found in that region. One dryer had a concave design; the other was W-shaped. Both were built for $40 or less.

Both were effective, but the concave design was a little cheaper to build and dried tomatoes faster. The research showed once again that solar power can be a game changer in many places of the world, especially where electricity is unavailable or unreliable.

Solar power can help solve world problems, as noted in this Merced Sun-Star recap of the UC Merced symposium, and its use is likely to become more widespread as solar cells become cheaper and more efficient. There are some pretty impressive minds attempting to accomplish that, including some at Merced, which is fast becoming a leader in solar research.

Students and researchers from UC campuses in Merced, Berkeley, Davis, Santa Barbara and San Diego, and other universities, are working hard to improve the efficiency of solar cells. Costs are dropping "spectacularly," said Sarah Kurtz, interim director of the National Center for Photovoltaics and principal scientist at the National Renewable Energy Laboratory.

Meanwhile, the industry is expanding at a robust rate. Photovoltaic shipments are doubling every two years, and costs are falling.

Today, researchers are developing solar cells that are at least 40 percent efficient. Kurtz said 50 percent is possible as economies of scale, new approaches and advancements take hold. "The challenge is to make high efficiency with low cost and high reliability," she said.

Many researchers are focusing on making thinner cells that concentrate light in smaller spaces and have the potential to change the market. Meanwhile, the California Energy Commission is boosting research through its Public Interest Energy Research (PIER) program, which helps finance projects related to research in clean energy and energy efficiency. The agency estimates 2,128 Californians were working in early 2011 in jobs directly related to active PIER-funded research, and more than 3,000 other jobs are indirectly related.

PIER funds have aided efforts at UC Merced, where a grant for $75,000 led to the creation of a business in San Jose that has 180 employees and $100 million in investment. Another research grant from PIER for solar thermal technology was the catalyst for two start-up companies.

"We are looking for breakthrough technology," said Prab Sethi, senior project manager at the California Energy Commission.

Breakthrough technology or industrial revolution? Technology is advancing so fast, it's hard to decide.

Solar joins the right-price energy club

Solar parity is here.

Honest. That's what a new study from Queen's University in Kingston, Ontario says.

"Given the state of the art in the technology and favourable financing terms it is clear that PV has already obtained grid parity in specific locations," say K. Brawker, M.J.M. Pathak and J.M. Pearce in the report, "A Review of Solar Photovoltaic Levelized Cost of Electricity."

That and technological innovation, which is driving up solar system efficiencies, could open new markets and spur significant development of projects focused on harvesting the sun's energy. In California's San Joaquin Valley, we're already seeing the results with about 40 projects in the works in Fresno County and at least as many in nearby counties.

Ferocious cost reductions

Sami Grover, from treehugger.com, put it this way: "With the solar industry delivering ferocious cost reductions, falling as much as 11 percent in just six months, it's little wonder that some predict that solar will be cheaper than coal in the very near future."

A cleantechnica.com editor says the findings by Queen's University don't even take into account health, energy security and environmental costs of fossil fuels "and it STILL finds that solar has reached grid parity in many places."

The recent Durban Climate Summit clarified the dangers of allowing pollution to continue without restraint. The cost and potential damage of unparalleled production of greenhouse gases is impossible to determine. But one thing's for certain, it will be huge.

The rapid innovation of solar technology offers a way to cut into reliance on fossil fuels. Whether it will make a difference is anybody's guess.

Solar interest high

A solar research symposium at the University of California, Merced, Dec. 9, 2011, draws students and researchers from UC Merced's program, which is fast becoming a leader in solar research, and University of California campuses of Berkeley, Davis, Santa Barbara and San Diego as well as other universities. All report that their programs are working hard to improve the efficiency of solar cells.

At the symposium, Sarah Kurtz, interim director of the National Center for Photovoltaics and principal scientist at the National Renewable Energy Laboratory, tells my co-worker Sandy Nax that costs are dropping "spectacularly."

Nax also reports in a recent post that the industry is expanding at a robust rate with photovoltaic shipments doubling every two years.

Gaining efficiency

While many photovoltaic cells on the market range between 12 and 20 percent efficient, moves are being made to increase that number significantly. However, those technologies also cost more. "The challenge is to make high efficiency with low cost and high reliability," Kurtz says.

Some in our sun-drenched valley are concerned about seeing solar panels everywhere, especially on prime farmland. Nax tells me that efficiencies reduce solar's footprint and likely will improve its image, especially amongst concerned farmers.

That and estimated $1 per watt equipment costs will go a long way toward influencing standards that include photovoltaic panels as part of nearly every newly constructed building or major retrofit and remodel. Toss in escalating electricity rates, and solar may become as common as flat-screen television sets in American households.

But rather than offering entertainment, this electronic device will create a new era of distributed energy.

Nothing's easy

There will be challenges. For instance, what happens when the sun falls below the horizon? Cheap solar provides options that weren't otherwise available. Perhaps production of hydrogen will become more widespread that either can be used in fuel cells or in other applications.

Political leaders also will have to knuckle under and institute more laws like California's Global Warming Solutions Act, which seeks to reduce the state's greenhouse gas emissions to 1990 levels, and the requirement that utilities get a third of their energy from renewable sources by 2020. Otherwise, the incentive by the private sector to start figuring out cleaner alternatives might not great enough to foster widespread change.

It can be done. Even at Durban, which drew representatives from 190 countries, leaders in the final hours of the Climate Summit put together what some media sources call a road map to a legally binding climate treaty by 2020.

We'll see.

Solar's Emerging Power In Central California



Solar power continues to expand in the central San Joaquin Valley, where projects in Fresno and Tulare counties are coming online. Today, PG&E symbolically flips the switch on three power stations near Five Points that will deliver enough solar energy to run 15,000 houses. Here is more from The Fresno Bee.

And here is a report on an interesting project a county away, where Dinuba officials will affix more than 4,700 solar panels to a landfill, and then use the 1 megawatt of power to operate the city's wastewater treatment plant. Typically, those types of facilities are among a city's biggest energy hogs.

Dinuba isn't the first city to use solar energy to decrease power bills at its water treatment plant, and likely won't be the last, as we reported in this blog that outlined similar projects in the Valley - and other possible uses for solar.

Solar is making its way onto rooftops, into agriculture operations and even onto roads. How much it expands remains to be seen, but the potential is sunny, considering California's 33 percent renewables mandate, the falling cost of residential systems and improving technology.

Just yesterday, folks at at UC Merced (oh, how we love UC Merced and its top-notch research programs!) announced a new kind of solar system that doesn't have to track the sun. Read more here in the Merced Sun-Star.

Maybe, Gov. Jerry Brown was right when he predicted a solar revolution in California.

The Coming Solar Energy Revolution in California and the San Joaquin Valley



It's not often that tiny Fowler hosts the governor, but that's what happened today when Jerry Brown used the Fresno County community of 5,500 people and a high school jazz band as the backdrop for signing three renewable-energy bills into law.

The legislation allows Fowler Unified School District to save $14 million in energy costs over 25 years; authorizes the California Public Utilities Commission to collect funds for renewable-energy rebates (typically, about $83 million each year); and requires the state Department of Fish and Game to accelerate its permitting process for clean-energy projects.

The Fowler school district will affix solar panels on Marshall Elementary, which will enable the district to save almost $500,000 the first year. But it won't be the only school in the state to get solar energy. The bill, SB 585, authored by Sen. Christine Kehoe D-San Diego, authorizes $200 million for the statewide California Solar Initiative, according to Brown's office.

Brown's office noted the bills were signed on the same day the San Joaquin Valley Air Pollution Control District issued its third dirty air alert of the week.

"California’s children deserve clean air and a bright future,” said Brown. “They deserve good jobs and a strong economy. The bills I signed today are part of a solar-energy revolution that is sweeping our state. These bills will help create jobs, lower electric bills and clean up the air we breathe.” Learn more here and in this Fresno Bee story.

The projects will help meet the state's objective of 20,000 megawatts from renewable sources by 2020. The California Solar Initiative, funded through utility companies, gives rebates for solar installations on commercial, industrial, nonprofit and government and other non-residential buildings, including schools.

The Department of Fish and Game bill, introduced by Michael Rubio, D-Bakersfield, could help speed up applications in the Valley and high desert region of Kern County, where, according to Fish and Game officials, thousands of acres of proposed clean-energy projects are proposed.

The Valley, with high power bills, lots of land and sun, along with a midstate location and access to transmission lines and bright minds at UC Merced, Fresno State University and Cal Poly, could be a leader in solar and other types of clean energy.

Brown's choice of words, describing a solar-energy "revolution" in California, was notable. His highly public event was on the same day that President Obama announced the winners of a $37 million "jobs and innovation" challenge that include a proposed collaboration between high-tech capital and technology in San Diego with the natural resources of Imperial County to create a "mega-region" of renewable energy.

The opportunity in California is staggering.

Valley Farmers Turning To The Sun To Power Their Operations


We've written time and again about how the San Joaquin Valley is ideal for solar and other types of renewable-energy programs. That's due in part because the land is flat - and there is lots of it - and because leaders of the region's largest economy are discovering the power of alternative energy.

Farming is a $20 billion enterprise here. Valley growers produce nuts, fruits and vegetables that are sold worldwide. Agriculture requires much energy, and farmers are increasingly turning to renewable sources to provide that power.

Here are some examples, including a blog that details how California growers lead the nation in the production of renewable energy. Today's Los Angeles Times showcases a new 6-acre array of solar panels that will provide 70% of the power to a pistachio orchard. Here's a press release on the announcement.

We expect solar and other types of alternative to expand in the resource-rich and geographically-blessed San Joaquin Valley as pressure mounts to meet a 33% statewide renewable-energy standard that awaits Gov. Brown's signature.

The Valley, with thousands of acres of available land, ample sun, a mid-state location close to major population centers and University of Merced's cutting-edge research, could be positioned to be a leader in renewable energy.
