San Francisco Giants - play solar ball!

Thursday, September 28th, 2006

After a some what typical fall foggy start in San Francisco, the sun burned through the clouds, and a fun game was enjoyed by all. In the next couple of weeks, we hope to share some stories from those that attended the game…but in the meantime, we just had to share a few pictures.

Yesterday PG&E sponsored the second annual Giants Solar Day with the San Francisco Giants. 20,000 thousand fans received a commemorative PG&E Giants Solar Day hat, and hopefully had some solar energy seeds planted for our energy future.

As a part of the event, PG&E and the Giants recognized PG&E’s solar efforts-

  • PG&E leads the nation in grid-connected PV, and is third in the world when it comes to installed solar capacity, and
  • The PG&E Solar Schools Program is now in our third year- our kids got to take the bases and meet real Giants!

Together, we hoped to swing a few more fan’s hearts and minds towards solar energy in their own schools, homes, and businesses. There was also a lot of information on energy efficiency actions people can take immediately- everyone can save a little energy and $ while preparing for a solar energy installation…in fact, it makes all our energy go further.

California is aggressively pursuing a ten year California Solar Initiative, and the Governor recently signed the Million Solar Roofs Initiative into action. We hope our schools, and the communities in which our projects occur, will be a part of catalyzing the success of ambitious solar efforts around the state, country, and world.giants-meet-the-kids.jpg
If there are any other baseball teams out there looking to bring new energy, and fans to their ballpark…if you have a favorite team…let us know! Play ball! We’re working on our solar energy rally for next year.

Solar Schools in Northern and Central California

Wednesday, September 20th, 2006
We’ve posted a few stories on specific projects in northern and central California, but we thought it would be helpful to explain the program in more detail, and give a little behind the scenes look. Pacific Gas & Electric Company (PG&E) launched their first solar schools pilots in 2004, and expanded in 2005, and 2006. The program is open to all public low-income/underserved schools in PG&E territory, which is approximately 48% of the state of California.
pge-map.jpg

There are three main components to the PG&E Solar Schools Program:

  • Installation of $20,000 solar generation systems for educational use. Up to 30 schools will be selected to receive these systems at no cost.
  • PG&E will underwrite the costs, allowing 600 teachers to attend science curriculum training seminars.
  • Bright Ideas grants. PG&E will award up to $200,000 in cash grants of $2,500 and $5,000 for solar science projects.

The Foundation for Environmental Education is responsible for helping with the installation of systems; however, we work very closely with PG&E and NEED throughout the process. The installation starts with a competitive process in which schools apply to the PG&E Solar Schools Program (www.pge.com/solarschools) with schools telling us why we should select their school. The installation is standardized for consistency throughout the state.

Some people ask us, “Why don’t you put the systems up on the roof? It’d be cheaper, and easier!” There are three primary reasons. First, we want to have a standard design that everyone has in common so that they recognize they’re all part of a larger solar schools team…and all plugged into the same sun.

stockton-pv4-small2.jpg
Second, we try to install the systems as consistently as possible to ensure we maintain as many constants as possible in our solar experiment. PG&E provides a commercial grade data monitoring system that tracks the complete energy and environmental performance of all of the systems installed in real-time (there will be 60 by the end of the year!). Do hotter climates make for better producing systems? How does the coastal fog affect systems? We want students at a school in Fresno to be able to compare the electricity generated at their school with a school in Merced…and a school in Mendocino and a school in Placerville. If the systems are all different sizes, it becomes more difficult to see the impact of longititude and latitude and altitude, and weather on the electricity generation.

Third, we don’t want systems that are out of sight and out of mind. There is nothing that compares to being able to stand underneath 1kW. Kids will often look up in wonder and say, “Wow, that’s 1 kilowatt…what is a watt…does that power my whole school?” The answers are abundant, and the questions keep coming…that’s what we hope for. If we put systems on the roof, they may go in cheaper and quicker, but they may quickly become invisible to the students at the school and the new students starting at the school each year. These projects are not designed to be hidden from everyone except the math and science clubs. These systems are designed to help all of the students at the schools improve their understanding of math and science.

solar_panel_02-san-jose.jpg

In 2004, we added ten systems…in 2005 we added twenty more…as we type this story, we are in the process of adding thirty more schools! There are no batteries in these systems. These are all grid-tied solar electric systems. The process takes several months to complete. At the end of the process, there is a ribbon cutting event or some public announcement event that recognizes the school for being selected and for allowing the PV system to be installed at their school.

The installation process begins with site selection, plans, and permits. The installations are scheduled around the schedule at the school. The standard system is approximately 1kW and occupies roughly a 12’ x 12’ footprint. The lowest point of the system is at about 8’. When we are selecting a site, we look for the site that best “fits” the school. Factors that affect the “fit” include: Proximity to classrooms (where teacher champions are located, near an organic garden or outdoor education area, etc.); close to point of interconnection (as all these systems are tied to the PG&E grid, they are wired into a local panel and must be close to the PG&E meter); good solar access (limited shading, and not under a tree, and in a visible/secure location). Once we all select the site, we bring in our installation team to finalize designs and begin the construction process.

There is also a teacher training part of this initiative, but the teacher training is open to all schools and not just the schools selected to get a PV system. If the teachers have a system at their own school, they can use the monument and installation as a teaching tool as well as the data monitoring. Teachers also receive curriculum, and hands-on teaching tools. There are also Bright Ideas grants available to public schools anywhere in our service territory.

You can see what our systems are doing right now by going to this site: http://pge.fatspaniel.net/SunPoweredLearning. Not all of our systems are online yet- there are occasionally difficulties working through the local networks of schools, and allowing the data to flow freely across the internet. Firewalls often block the data from going to the Web site. We get notification of these fire wall problems and we call the school districts and have them removed so don’t be alarmed if you don’t see live data for a particular school. You should click on the icon that says “Week” or “Month” and you can see the system has been working. And the data is not lost. When the firewall allows the data to flow out, the system data is automatically updated.

Another thing to remember is that when installations are first completed and the systems turned on, the live data starts off in a private password protected site until the system has been checked out and the school’s IT people feel comfortable with the live data leaving the school. We keep it password protected until the district allows us to post the data on a public Web site.

Each of these solar electricity installations must go through the same interconnection process that any solar electricity system must go through if it is connected to our grid. This involves some paperwork and inspections. Plans are reviewed, and meter numbers are confirmed. It may seem time consuming because the systems are only 1 kW in size, but they still generate electricity so they must still go through the same process as a 10 kW or a 50 kW. We try to make this process as easy as possible for everyone involved.

Feeding a Village with the Power of the Sun

Tuesday, September 19th, 2006

solarcooker7.jpg

The Fairmount Elementary School village, in El Cerrito, California, consisted of 270 students, 15 teachers, 10 parent volunteers and 7 special guests…and they still had food left over. It was this kind of abundance and community participation that transformed “To Feed a Village” from a school project into a community happening, one that the students and parents have continued to talk about well into the summer.

solar-cookers.jpg

When asked why the Asian-style rice her class made inside a solar cooker turned out so well, Kindergarten Teacher Doris Reeves pointed up to the sky and said, “Because it was made by God.”

This statement highlights the great enthusiasm with which the teachers and students of Fairmont Elementary embraced the “To Feed a Village Solar Cookout.” All agreed that it was a rousing success. The children were filled with pride and excitement, and teachers are already looking at ways to incorporate solar cooking into their curriculum for next year using the supplies and knowledge provided by our Bright Ideas grant. This project was funded by the PG&E Solar Schools Program Bright Ideas grant.

The designers of this project (School Site Council Chairman Reyel Daystar, Michaela Daystar, and teachers Daneen Cali and Patricia Colbern) envisioned the potential of this project, but the event exceeded their expectations. It has heightened classroom discussion about, and galvanized our community around, renewable energy. This was the first time in the schools history (the first Fairmont Elementary Schoolhouse was built in 1897 when the city was called Rust) that the community united around the cause of conserving energy and teaching sustainable development.

img128.jpg

Goals at the start of this project were twofold: 1. Introduce renewable energy science education into each classroom at Fairmont in a way that was fun and engaging for the children. 2. Bring official City and media attention to Fairmont, a school serving many low-income children that has a rich history and rising test scores, and yet has faced the possibility of closure by the School Board twice in the last three years.

The success of the first goal could be seen in the excitement the students had for the project—from the introduction assembly, through their classroom cooking experiments, and during the final event. Seven out of the eleven teachers who returned project evaluations cited the positive science learning and the hands-on learning techniques as the most positive aspect of this project; and four listed the participant enthusiasm. Each teacher was invited to incorporate the solar cooking experiments into their curriculum in whatever way they felt was best. Some had time for only the most basic experiments, while others used the project as a springboard into discussions about the environment, resource conservation, fossil fuels, the earth’s rotation, and even some of the social benefits of using clean energy sources. Some classrooms designed and built their own solar cookers, as did a pair of industrious fourth grade students who did it on their own.

solarcooker4.jpg solarcooker5.jpg solarcooker3.jpg

During the two week span of the project, each classroom made a journal to chronicle their attempts at cooking. The students added colorful drawings of the cooking along with their commentary. These journals speak volumes about the pride and enthusiasm with which the students embraced the experiments, and also to their lessons learned.

The designers of the project acted as facilitators, and learned that along with excitements comes distraction. At least one teacher mentioned that during the week of classroom experiments, there was a lot of time during which the cookers were outside cooking and the students wished to keep an eye on them, which disrupted other lessons. This is a reflection of the experimental nature of this project as a first attempt to introduce renewable energy science into the activities of the school. Several of the teachers have begun to brainstorm ways to further integrate the new equipment and lessons into the regular curriculum of the school. The Fairmount Elementary team feels confident that as the teachers and students become more familiar with the process, such disruptions will be minimized.

The weather was the other major difficulty the teachers mentioned. While the sun is predictable, it’s not wholly dependable to do exactly what one wants at any given time during the day… One of the teachers pointed out that in El Cerrito’s microclimate the weather was uncooperative. This project was undertaken around the middle of the year in 2006. During the first few days of cooking practice the sky was overcast, preventing successful cooking. The students persisted and by the second week of practice the weather changed, bringing sunshine and solar cooking success. Perhaps the student’s persistence and enthusiasm coaxed the sun out of cloud seclusion. On the day of the cookout, there was not a cloud in the sky. Some of the journals mention the student’s disappointments about the weather, but also reflected the student’s new awareness of the weather as a force in our lives, and of our specific weather patterns.

As a secondary benefit, the solar ovens and water pasteurizers have been included in each classrooms emergency preparedness kits, adding safety education to the learning experience.

This project also fulfilled the team’s second goal, which was to promote Fairmont as an innovator in energy education. Many teachers and parents mentioned the press coverage we that got from the West County Times. One parent volunteer sent out a wonderful press release, and invited many people from local government and organizations. Our guests included: West Contra Costa School Board member Karen Pfeifer; Richmond City Council member and Mayoral candidate Gail McLaughlin; David Marin of the El Cerrito Green Party; Eric Bloom of the Richmond Annex Group; Barry Scott from the NEED project; Karalee Browne from PG&E; Alyssa Newman from the Foundation for Environmental Education; community activists/social workers Khaleedah and Ansar Muhammad; and Julius Davis, a volunteer from Solar Cookers International and the Great Uncle of one of our facilitators.

The success of this project was marked for Michaela, one of the project designers, when a fourth grade student showed her the shoebox cooker he and his friends made for the event. Michaela displayed their cooker along side all the others. The pride and respect they felt when they served their friends food out of their creation was exactly the kind of empowerment this project was designed to instill in our students.

Worthington, Ohio: Bluffsview Elementary-the first “Learning from Light” School

Tuesday, September 5th, 2006


In 1998, American Electric Power (AEP), one of the world’s largest electricity providers, started an initiative called “Learning from Light.” It was a simple idea created by Paul Loeffelman and Dale Heydlauf and John Hollback of AEP. The plan was simple. Small solar electricity systems would be added to schools in a way in which the panels could be visible to the students at those schools. In the past many solar electricity systems had been installed so that the entire system was hidden on the roof. It was efficient, but it wasn’t all that effective.

p1010187.jpg

“Out of sight, out of mind.”Paul Loeffelman had the idea to put the panels down on the ground at the top of poles so that the panels would be visible to the students at all times. The initial installation went in at Bluffsview Elementary in Worthington, Ohio.

They went further by combining a teacher training piece to the initiative and initially AEP personnel visited classrooms to help explain electricity and solar electricity to the students. This aspect of the program has been coordinated by Mary Kay Walsh and Barry Schumann over the last 8 years, but is primarily administered by the NEED program, the National Energy Education Development Project.

p1010021.jpg

It was the Principal of Bluffsview, Donna Kelly, who came up with the idea of a celebration after the installation. Paul Loffelman liked the idea so much he made it part of every Learning from Light project from that day forward. At the first one at Bluffsview, they had US Congressman Ralph Regula and Dan Reicher from the US Dept of Energy, and a long list of presentations and awards by the Worthington School Board members, the Mayor of Worthington, a County Commissioner. Every student at the school wore a T shirt, had a button, and wore sunglasses. It was a huge event attended by more than 700 people and is still the model used today by solar school projects all over the US. The keys according to the rule set down by Paul Loeffelman, “one hour and we are out of there.” And this can be difficult with politicians attending every ribbon cutting because, as we all know, they often have trouble cutting their talks to 5 minutes or less, but to this day we seldom have a problem with it. In fact, at the Washington Lands ribbon cutting in Moundsville, West Virginia, the Governor spoke…and kept his talk to about 7 minutes.

Ohio Visitors Tour the School

twenhofel-2.jpgThere was a tour on August 9th at the Twenhofel Middle School in Independence, Kentucky. The tour was organized by Glen Kizer of the Foundation for Environmental Education. The tour was conducted by Robert L. Lape, Facilities Director/Architect for the Kenton County Schools, and Joseph Ahrens Hayes of Robert Ehmet Hayes & Associates, the architect for the school.

twenhofel-1.jpg

On the tour were:

Ohio School Facilities Commission: Franklin Brown, Bill Prenosil, Architect with OSFC, Mark Wantage, Maintenance and Commissioning Program Lead, Tom Brannon, Project Closeout Administrator, Been Kuo, Mechanical Engineer and Plans Reviewer, Tara Bonner, OSFC Student (Mechanical Engineer) Intern.

Fanning/Howey: Terrance Liette, PE and Michael E. Hall, AIA, REFP, LEED AP.

The purpose of the tour was to provide the group from Ohio with an “up close and personal” look at this wonderful school in Independence, Kentucky. It is called a “high performance school” or a “green school” or an “energy smart school,” but basically these are just variations of the concept that a school building should include the following benefits:

  • Better student performance
  • Increased average daily attendance
  • Increased teacher satisfaction and retention
  • Reduced energy and operating costs
  • Positive influence on the environment
  • Ability to use the facility/building as a teaching tool

twenhofel-3.jpg twenhofel-8.jpg twenhofel-6.jpg

This particular school is named after a Dr. Twenhofel who donated the land to the school district. It will be designated an “Energy Star” school by US EPA and a “LEED” certified school by the US Green Building Council.

The tour started with handouts and an opening welcome to the visitors from Ohio followed by a short summary of the building using the touch screen smart board that illustrates the major “green” features of the building including the geothermal heating and cooling systems, the daylighting, the water capturing system, and the solar electricity system.

Mr. Lape also described the competition among the three grades (7th, 8th, and 9th) at the school to see which wing would use the least amount of energy.

The tour included a number of classrooms so that the group could see the difference between how the daylighting was handled in classrooms on the south side of the school versus the classrooms on the north side of the school. The daylighting system required extensive collaboration between all the design disciplines the benefits of which go well beyond the daylighting system itself. As it provides natural full-spectrum light, the daylighting system also reduces energy consumption and lowers internal heat gain allowing the cooling equipment capacity to be reduced. We also walked up in the hidden part of the school where the wiring and the pipes run. This is where the geothermal heating and cooling systems operate. The most popular feature of the geothermal heating and cooling system is the fact that each classroom gets to set its own temperature. The most important part of the system is that it only uses half the energy of a typical heating and cooling system saving money and reducing pollution.

twenhofel-5.jpg

The group saw the plexi-glass ceiling panels that enable students in the science classrooms to use their school as a learning laboratory. The group also saw the system that catches rain water, cleans it, and pumps it back into the school to flush toilets. This recovered water is also used to water the lawn and the football field. Finally, the group wasshown the solar panels. This required us to go up on the roof. The 24 kW photovoltaic or PV system provides about 30% of the electricity being used by the school.

twenhofel-7.jpg

The hope is that by conducting these kinds of tours people from other areas, like our group from Ohio, can see a working high performance school in action and that similar schools can be built in Ohio, and around the country.

Wheelersburg Middle School - Ohio

Friday, September 1st, 2006

Story submitted from Joe Lester

I am the Grandfather of a little girl at the Wheelersburg Middle School. There is a solar electricity installation system on the school. The panels were installed on poles and they sit outside the science room near the front of the school. Anyone who drops off kids or picks up kids at the school can see the solar panels.

Our community is small so it was important for us to get these solar electricity system or PV system. There is a lot of things that we in a small town don’t get, but we want the best educations for our kids and grandkids that we can get and this PV system will help our kids learn science and math.

wheelersburg.jpg

The system was donated by American Electric Power and the Ohio Dept of Development’s Office of Energy Efficiency and the Foundation for Environmental Education. The biggest expense of the installation was the panel array and the panels were donated by American Electric Power. We dealt with John Hollback and Paul Loeffelman at AEP.

We raised money for our part of the project cost. I personally donated $1,000. But most of the money was raised in a “Walk-a-thon” in which we had more than 2,000 people donate $1.00. That is pretty good for a community of $5,000 people. Many of the people who donated money were teachers and school staff and parents of the kids at the school.

At the ribbon cutting, Congressman Ted Strickland’s Office (he is from this part of Ohio) sent someone from Washington DC to speak. Sarah Ward from the State of Ohio came and John Hollback spoke from AEP.

The Ohio Energy Project provided teacher training for our school.

I am writing this story because we are so excited about getting a Web based data collection system that will enable our students to see how much electricity is being generated by the solar panels in real time. Our kids will be able to compare how much electricity we are generating with similar systems in Chicago, Illinois, and Oakland, California. They are excited about this new addition to our system.

In the picture I have included Larry Schoff from the US Dept of Energy and Elaine Barnes (then) from the Ohio Office of Energy Efficiency and our previous Superintendent John Eaton.

We are now building a new high school and we had hoped to put a large solar array on the roof of the school, but I am not sure that is going to happen. I will provide an update on this in a few months.
