Getting the renewable energy mix right

I was out at Desert Mirage High School in Thermal on Wednesday, talking with students in the school’s green tech career academy about what I do as an energy and green tech reporter — ask people a lot of questions about very technical things and try to turn it all into plain English.

Most of the students said they want to work in a green tech or engineering field, so I also spoke about the importance of good communication skills and the inestimable value of being able to write clear, grammatical sentences (old school, I know, but it’s something I’m actually rather passionate about).

One of the students asked me what I thought the best form of renewable energy is, and I stopped for a second. Being a reporter, one always stops when anyone asks you what you think the best of anything is, because one cannot appear to be biased or endorsing one thing over another.

Luckily in this case, it was not a problem. What I said, in essence, is that , with renewable energy it isn’t a matter of better or worse, but rather how the different forms fit together and complement each other.  We need them all.  The wind blows best at night — so we can have renewable energy on the grid ready to go in the wee hours and early morning.  Then photovoltaic, rooftop solar comes on in the morning and peaks in the afternoon for daytime use.

Geothermal can fill in the gaps, it is 24/7 baseline power. Solar thermal technology also has the potential to fill in the intermittent gaps created by wind and rooftop. While big solar thermal projects, such as BrightSource Energy’s Ivanpah plant, have major environmental impacts and have been difficult to perimit, their technology — using solar energy to heat fluids and run a traditional generator — provides a more reliable power source than rooftop solar.

If you add storage to the picture — and it’s coming, in the foreseeable future — you have the possibility of a grid that can, at least in theory, run almost entirely on clean, renewable sources with the inevitable economies of scale and lower prices.

This is, at least in part, the argument that some advocates are now making as California develops a renewable energy portfolio that will provide 33 percent of the state’s power by 2020. The utilities have largely loaded up on cheaper photovoltaic projects that by their very nature mean we will need some kind of fossil fuel backup to balance the intermittency of solar.

More reliable forms of renewables, such as solar thermal, are more expensive, but cost alone should not be the only factor considered.

Which brings me to BrightSource. Even as the company’s Rio Mesa project looks shaky – possibly losing a power purchase agreement to sell half the power from the plant and facing millions in mitigation costs to offset environmental impacts — investors have given the company a vote of confidence in the form of $80 million in new equity funding.

In a press release issued today, company executives announced a list of new investors –

Alstom, a global leader in the world of power generation, and VantagePoint Capital Partners lead the round. Additional investors include DFJ, CalSTRS, DBL Investors, Goldman Sachs, Chevron Technology Ventures and BP Ventures among others.

The company now has $615 million in equity funding.

Alstom is a French energy multinational and VantagePoint is a major player in clean tech investments. That major fossil fuel companies such as Chevron and BP want in also speaks volumes.

The bottom line is, every form of energy, whether fossil fuel or renewable, has some kind of environmental impact; that is the unavoidable trade-off we make for the power.

Figuring out the best value and right balance of renewables going forward will be a complex process, involving careful thought and calibration of lots of competing and conflicting factors.  Hopefully, some of the students I spoke with today will help find the solutions.

And they’ll be able to write about it in clear, grammatical sentences.

Creating the green jobs pipeline

Fourteen teachers from across the Coachella Valley spent their summer vacations learning about  job opportunities in the region’s green technology field and how to design classroom projects that will ensure their students have the necessary skills and knowledge to fill them.

The summertime “externship” program is part of the Coachella Valley Economic Partnership’s Workforce Excellence program — developed in partnership with College of the Desert — which is tackling the region’s Achilles heel for diversifying the economy and drawing well-paid, green tech jobs, our underskilled workforce.

I sat in on a program recap and celebration Wednesday at the CVEP offices in Palm Springs and it was easy to get caught up in the teachers’ excitement about the program and how they’re taking their summer experiences into the classroom.

The idea behind the program is to bring teachers into direct contact with city and business leaders to talk about the kinds of jobs that may be available in green tech and what kind of job skills students will need to develop now to prepare for the positions.  The teachers who participated are already teaching in green career academies — set up through CVEP’s Career Pathways program — where students are focused on preparing themselves for green jobs or, in the case of two teachers from Indio High School, laying the groundwork to launch one.

Pathways has also started highly successful health care academies at several valley high schools, where the focus is preparing students for careers as doctors, nurses and other health care providers. The career academy program has been drawing increasing attention as a national model for its comprehensive approach to workforce development.

Programs start early in elementary and middle schools and build to the high school academies, with job shadowing, mentoring and internship opportunities for students. CVEP also stays connected to valley students who leave for college — with scholarships and local internships — so hopefully they’ll come back here to work.

Right now we have two green academies in the valley —  the Renewable Energy Academy of Learning, or REAL, at Desert Hot Springs High School and the Green Energy and Technology Academy, or GrEAT, at Desert Mirage High School in Thermal.

For the externship program, the teachers made a series of field trips, visiting geothermal sites at the Salton Sea as well as Mission Springs and the Coachella Valley water districts, the Imperial Irrigation District and the cities of Coachella, Palm Desert and Desert Hot Springs to find out about their energy efficiency and renewable energy programs.

The teachers also got coaching in project-based learning, said Donna Sturgeon, Career Pathways’ work-based learning coordinator. Starting with the information about the kinds of jobs that will be available in a specific green tech field, such as water conservation, the teachers take the basic skills the students will need for such jobs and work backwards, breaking them down into smaller, discrete tasks or skills that can all be linked to a class project. The project-related tasks and skills are also linked to state-mandated learning standards.

So at Desert Hot Springs REAL program, Todd Berg, a career technical teacher, has his students working on designing a grey water recycling system for the school’s car wash system, to take dirty water and recycle it for other uses, rather than just leaving it as polluted run-off.  The tasks involved range from figuring out what kind of grey water system might be needed, researching options, finding out about the legalities — what kind of permits might be needed — and creating blueprints of the system.

But the program is not just technical. Brian Martin, a social studies teacher who took part in the summer externship, is focusing on the impact of clean water on communities, having his sophomores and juniors look at the role of water systems in the growth of cities and how clean water is regulated.

Similarly, Elisa Santillan and Renee Miletic, English teachers at Desert Mirage’s GrEAT program, are now working with their students on presentation and communication skills, working up to interview skills, they said.

The skills Miletic is focusing on include “being able to explain things and answering questions; being in situations where they are in competition, making it into an opportunity to connect with other people,” she said.

The GrEAT program is having a big impact at Desert Mirage, where 90 percent of the students are low-income. Now in its third year, the academy has 100 students, including its first group of 25 seniors.

The programs are getting both teachers and students excited. One teacher at Wednesday’s event  talked about having to practically throw his kids out of the classroom — they wanted to stay after school to keep working on their projects.

Beyond preparing students for green jobs, CVEP’s program is busting many of the stereotypes about the valley’s low-income students — that they don’t have the smarts, motivation or discipline to succeed. For the teachers, it’s an opportunity to raise their professional expertise and “orient themselves twoard the new industry,” said Larry McLaughlin, director of COD’s Desert Energy Enterprise Center in North Palm Springs.

Kim McNulty, program manager for Career Pathways, noted that the valley has 71,000 K-12 students, 20,000 of them in high school and 3,000 of those in career academies.

What Career Pathways is doing is showing these kids that education — math, science, English, the basic skills — aren’t just dry subjects; they have real-world applications that can open doors for themselves and their families, while building diverse, sustainable jobs and communities across the valley.

 

 

 

 

 

People who climb on roofs: The GRID Alternatives Solarthon

It was one of those only-in-California moments. A residential cul-de-sac in San Jacinto – which is about 45 or so minutes out of Palm Springs, down Interstate 10 West and then a wildride on CA-79S, a swooping mountain highway — and the street is filled with people in jeans, T-shirts and hard hats, swarming up on roofs of the houses to install solar panels. 

It was the GRID Alternatives 2012 Solarthon on May 19, when dozens of volunteers gathered on Karlie Ann Court to install solar panels on eight homes, all in one day.  Based in Oakland, GRID is a nonprofit founded by two engineering professionals, Erica Mackie and Tim Sears, who believe you shouldn’t have to be rich to be able to afford solar panels on your roof.

GRID is the main contractor for California’s Single-family Affordable Solar Homes program, known as SASH, which is part of the California Solar Intiative. SASH is targeted at helping low-income families go solar, by paying 60 percent to 100 percent of the cost of an installation. To qualify for the program,  people must fit the federal definitions for low-income families.

This was a sore point for Shirl Papaian, a San Jacinto resident bicycling down the street, who questioned whether the homeowners there are truly low-income people.

“Anybody who can afford to buy homes like these aren’t in need,” she said. “It’s an outrage.”

But Mackie defended the project, saying the neighborhood had been built by the city for first-time, low-income homebuyers.

“A lot of people think homeowners can’t be low income,” she said, noting that statewide about 1.5 million homeowners qualify as low income.

The homeowners who qualify for GRID installations also have to have a home energy audit and enroll in state or federal programs promoting energy efficiency home upgrades, she said.

To date Mackie and Sears have helped put solar panels on more than 1,750 homes, cutting low-income families electric bills by an average of 75 percent. GRID Alternative estimates its installations will keep about 151,000 tons of carbon dioxide out of the air over the next 30 years.

The group has a lot of supporters in the Coachella Valley, many of whom made the trip to San Jacinto for the Solarthon. Desert volunteers ranged from a crew of solar trainees from College of the Desert’s solar training program to George Puddephatt, a solar job specialist with Riverside County Workforce Development in Indio, who usually is on the one helping COD program graduates find jobs, not climbing up on roofs to install panels. Hot Purple Energy, the ubiquitous Palm Springs solar installer, had an information table as did SunUp Energy.

Per usual, the folks from COD were a cross-section of the valley’s unemployed. Leo Adamski, 58, from Calimesa has been a carpenter for 38 years, but as he said, “There’s not a lot of framing going on.”

Adamski was there for the hands-on training opportunity, after the first three weeks of his nine-week course at COD.

“Now that we’ve gotten through some of the school, it’s a plus to see the panels bolted to the racks.”

Pamela Becker, 54, of Palm Springs was in coporate information technology and also did some real estate investment — before the recession. Now she’s on the brink of losing her house and is hoping the solar training at COD will get her off unemployment and back on her feet financially.  She said the hands-on training at COD is “exceptional.”

Joe Dolan, who previously worked with the solar program at COD, but now is at PetersenDean, a roofing and solar firm, was there to help and do some recruiting for the Riverside office he’s setting up, he said, over the barbecue lunch — burgers and salads and all kinds of yummy desserts — put on for the volunteers.

During lunch I also caught up with Dianne Randle, one of the homeowenrs on Karlie Ann Court who now has solar panels on her roof. Randle, a hospice nurse, said she’s looking forward to cutting down her monthly electric bills, which run around $150 (yes, relatively low by desert standards, but high for Randle who has a 15-year-old who, like many teens, doesn’t remember to turn off lights or computers).

Randle’s installation was also special because it was done by a team of women volunteers, Women’s Build, led by Anna Bautista, a diminutive woman from Los Angeles.

Solar and renewable energy in general is still heavily male, so I asked her if it was hard for women to break into the field.

“It might be intimidating,” Bautista said. “They’re just as capable.”

Mary Eike, another LA volunteer, was just bubbling. Getting up on a roof to install panels, wires and all is a kick, she said.

“I’ve always been interested in solar,” she said. “I love doing this.”  

Another valley contingent came from the green academy at Desert Mirage High School in Thermal. The students didn’t get up on the roofs, but they were all impressed with GRID Alternatives.

Their teacher, Arthur Kimball, seems to be on a one-man mission to expose the kids to all the job opportunities in green tech.

“The green academy is new; it’s cool to see all this,” said Marina Barragan, 17, of Oasis.  

Joe Rodriguez, 16 another student, said, “It’s inspirational for our community.”

Desert Mirage team takes 2nd in national KidWind competition

Great news from Arthur Kimball at Desert Mirage High School in Thermal — the school’s KidWind team, sophmores Arturo Gutierrez and Jesus Gutierrez (who are not related to each other), took second place in the national KidWind competition in Washington, D.C. April 27-29.

The KidWind program is aimed at getting K-12 students interested in  science, technology, engineering and math – referred to as  STEM — through having them design model wind turbines. The Desert Mirage team went to D.C. after taking second place in a regional competition here in the Coachella Valley.

Unfortunately, only four high school teams were in competition at the national level , versus many more teams from elementary and middle schools, Kimball reported. Still the Desert Mirage students’ second place was no easy deal; they were up against some top private schools, such as National Cathedral School from D.C., an elite girls’ school, which took first place.

“The competition was stiff,” Kimball said. “But they could indicate their learning by looking at other teams’ designs and making suggestions.”

The students and teachers also had time for a day of sightseeing, taking in the Smithsonian Space and Aeronautics Museum — where they were fascinated by propellers, Kimball said — as well as the Pentagon, Arlington National Cemetery and all the monuments.

And, Kimball said, they’re already looking forward to next year’s competition, when the KidWind organizers promised at least one high school team from each of the 20 states now participating in the regional competitions.

“Now we know what we’re doing, we’re going to bring the heat,” he said.

 

Desert Mirage wind kids head to DC

Today’s Renewable Energy Roundtable at UC Riverside’s Palm Desert campus started out with a presentation on some of the programs underway at area high schools to get kids interested in and prepared for careers in green energy and technology.

Arthur Kimball, who has started a green academy at Desert Mirage High School in Thermal, reported on the impact of the recent KidWind competition — in which area high school teams competed in designing and building model wind turbines. A Desert Mirage team placed second, making them eligible to go to Washington, D.C. for a national competition, April 27-29.

The winning students have since gone to Saul Martinez Elementary School in Mecca to teach a group of 5th graders about wind power and turbine building, but Kimball said, the word quickly spread around school and soon, everyone was trying to crowd into the cafeteria where the wind presentation was taking place.

The only solution was to ask the Desert Mirage students back for a schoolwide presentation.

Kimball sees the upcoming trip to D.C. as a chance for his kids to get an even better idea of the career and education opportunities available to them in green tech. He did a little ad hoc fundraising at the roundtable because, he said, while his program is state funded, none of the money can be used for out-of-state trips. 

After announcing he was short $2,500 to for the trip, a basket was quickly passed — knocking close to $500 off the shortfall.

Anyone who wants to chip in can call Arthur Kimball at 909-633-5211.
