The sun is shining and if you don’t have solar on your roof, all that clean energy is left untapped.
This is a problem that GreenTown Los Altos’s Energy Chair Gary Hedden was bent on solving. So we created GreenTown Los ALtos’s “Unleash the Power On Your Roof”, a program aimed at providing solid deals from solar vendors to increase the number of solar rooftops in Los Altos and Los Altos Hills.
Catch Your Rays. Raise Your Efficiency.
With several vendors signed up, we know that now is the time to check out the power on your roof. If you’re interested, please let us know.
Hurry! Program Runs April 1 – June 30
The program’s benefits, including access to information and a financial deal you won’t want to pass up, run from April 1 – June 30. To help educate prospective buyers, and debunk any solar myths keeping buyers at bay, we’d like to host small gatherings. For this, we’re looking for anyone who has installed solar to be a spokesperson, or what we’re calling Solar Stars, to help others through the process. If you’re interested, please let us know.
We are not alone…
The severe California drought is part of a world-wide water crisis, a tidbit confirmed by Laura Allen, an expert on all things water. On Mar. 23, at the Los Altos Library, Allen presented a vivid picture of this crisis through expansive charts and pictures that told that story.
“Do you know where your water comes from?”
“Do you know where your water comes from ?” Allen asked an audience that filled the library program room. After brief comments on municipal water systems, we delved into the range of practical options for reducing water consumption in our homes.
High on the list? Everything from repairing simple leaks, to collecting rainwater and reusing household greywater, we learned that we can conserve a significant amount of water daily that collectively will make a difference.
In particular, laundry-to-landscape greywater systems are both low cost and simple to install. Allen explained the operation of several greywater systems and audience members had an opportunity to sign up for a hands-on greywater workshop.
Laura came to the talk with a large box filled with her new book, “The Water-Wise Home”. All copies were sold out by the end of the evening. The book is available at storey.com.
Have you ever noticed that 280 has become increasingly noisy? Ever wonder what it’s from? Or what can be done about it? Here’s your answer.
Noise levels from Highway 280 have become increasingly annoying for many people in parts of our community, measuring 60 to 80 dB at various times throughout the day. A new technology, already used by Caltrans on other parts of 280, called rubberized asphalt, reduces pavement noise by up to 90% (about 9-10dB) by improving the efficiency of tires. In addition, the environmental impact of roadway particles ending up in streams, makes for a potential mess in the precious water we do have.
The compound reduces the mini explosion that occurs when tires squeeze air above the roadway. The explosion causes tire and roadway particles to launch into the atmosphere and eventually settle on the ground and nearby streams. The explosion is the sound one hears from the tires of a passing vehicle. You can learn more about it here.
Since 2009 CalTrans has been repaving certain areas with this new technology (including areas of 280, north of us). The Town Council sent a letter to Caltrans requesting the same treatment for our segment of 280, but Caltrans informed them we’ll have to wait six years to have the asphalt applied. A copy of the Town’s letter can be found here.
One reason Caltran cited was a lack of complaints from residents in this section of 280. The stretch of 280 that runs through Los Altos Hills is the most populated portion of 280 between Hwy 85 and Hwy 92 and the group generating the petition insists it is “impacting quality of life and property values in our community”.
This petition requests immediate repaving from Page Mill Road to the Foothill Expressway Overpass. The petition will be sent to State Senator Jerry Hill, Assembly Member Richard S Gordon, and Caltrans Area Director Bijan Sartipi.

Twice yearly, GreenTown Los Altos holds its ReCycle Bike Drive. It’s a great opportunity to donate that bike you just don’t use anymore that would make someone in need, truly happy. We know. We’ve seen it.
The spring ReCycle BIke Drive is happening Sun. May 3 from 10AM to 1PM at the Blach and Egan Middle Schools.
Thanks to the many participants, both volunteers and donors, the semi-annual event collects over 50 bicycles that are cleaned, tuned, and given to local students. The generosity of our community is amazing.
Watching a no longer used bike transform into an object of joy for students is incredible to experience. I wish everyone who donates a bike could see the impact to students because of this program. Hope to see you there!
Yes, “green” can be done and it will be beautiful!
Saturday, Feb. 28, an open house on Marion Ave. in Palo Alto showed the way to how building green pays off in more ways than you can imagine.
Designed by architect Tali Hardonag and built by Chris Donatelli, the house has 92 Green Points with more pending. As a point of reference, the Palo Alto building code only requires 50 points.
The owners wanted more than the minimum. Eleanor, one of the owners, put it simply, “Wendy and I wanted to do the best we could for the earth.”
So how does one collect that many Green Points?
According to the architect, some of it is very simple and obvious:
- Add insulation to hot water pipes
- Install energy star appliances
- Put out a sign to let the neighbors know this is a Green project.
The other Green Points come from making choices. What appeals to the owners, what is the budget, what makes sense for the site. For this project that meant:
- The use of recycled fly ash in the concrete
- Durable and fire-resistant roofing materials
- High efficiency toilets and plumbing fixtures
- Advanced ventilation practices
- Low-VOC paints
- Energy efficient lighting and controls
- Solar hot water heating
- Solar photovoltaic and much more.
But it is more than the points. The end result is a beautiful home that is well built, comfortable and good for the health of the owners and the planet.
Well done, Eleanor, Wendy, Tali and Chris.
GreenTown’s GreenTalk Feb. 18 featured two great speakers sharing two great ways to save energy, and MONEY.
First up was David Siddiqui from Green Evolution Consulting. David told us about the main sources of energy loss in the home. It can be simple problems, like leaky or disconnected heating ducts, which apparently happens all the time with the typical house sprouting a 30% leakage rate. Clearly a huge waste of energy, and MONEY.
Button Up Energy Loss, Lock In Savings
To figure out where you’re “losing” energy, David recommends a whole house energy assessment instead of dissecting the problem contractor by contractor. Once the assessment is complete you’ll have a road map for improvements that make sense. The payoff? Improved comfort, better air quality, increased home value, and to boot, you’ll save MONEY.
Speaking of MONEY, there’s other ways to get money for energy improvements including rebates from Energy Upgrade California and PG&E, as well as good financing options available. For more info contact David .
Second speaker was Curtis Tongue, OhmConnect. Curtis told us about a demand response program is the proverbial win/win. It enables you to make MONEY for your school by reducing your electricity use.
A what? Demand response? With a Payback???
When energy demand is high, think a hot day in August with all the state’s air conditioners blasting away, then all available power plants will have to be on. The last ones turned on will be the least efficient, the dirtiest and the most expensive. In fact, Curtis told us that 15% of the cost of all electricity is for the 1% of electricity at peak demand prices.
With that much cost involved, PG&E will pay you not to use power. This is where OhmConnect comes in.
Their models reliably predict expected use (demand) and if you turn off your appliances, lights, air conditioner, etc. for just one hour you will make MONEY. It’s pretty simple, OhmConnect sends you a text, you cut your power and PG&E doesn’t have to turn on that inefficient, dirty power plant.
So how does this help a school? Since the dollars for a few hours here and there really aren’t huge, people find it more satisfying to pool them with other folks as a school fundraiser. The dollars add up and it really helps. Springer’s PTA did it!
Interested? You can sign up at OhmConnect, it’s free, it’s fun and you can start making MONEY for the community.

How to Create Your Own Water-Wise Home and Landscape
March 23, 7-9pm, Los Altos Library
With simple plumbing alterations and smart landscape changes, every home has the potential to create a sustainable water supply with an ecologically productive landscape. From reusing greywater, to collecting rainwater, to installing waterless composting toilets, our collective efforts can transform our home water systems. A recent study found that households saved an average of 15,000 gallons a year after merely installing greywater system. Learn how you can transform your own home so it conserves and reuses our precious water resources, while growing a bountiful garden. This presentation will teach you how. It will also include national trends, codes and regulations, costs, health and safety considerations, and system examples.
Sign up for a greywater workshop at seminar. Laura will also be selling her new water conservation book.

Most people start off the new year wanting to somehow be different than last year. A New Year’s resolution. A vow to make a bigger difference. A choice to make a change.
At GreenTown, we’ve kicked off four new initiatives in our core areas of Water, Watts (all things energy), Waste and WoW (Walk or Wheel). These complement our already full slate of events including creek cleanups, bike valet parking, educational meetings, ReCycle Bike Drives, community outreach, the Glass Pumpkin Patch, and the Farm to Table dinner and create more opportunities for community involvement.
Our initiatives need volunteers, so as you read about them, think of wearing some of these impressive shoes:
Water program: Defy the drought by getting to 15% “brown” in our town.
Like you, we continue to be concerned about the drought because we know though we’ve had minimal rainfall, it’s not nearly enough to get us out of drought territory. Hopefully, you already reduce water consumption and support a native garden instead of a water thirsty lawn.
Our water program members are very active, spreading the word about drought tolerant native plants, water wise irrigation, and educating water wise leaders. We hope you are the example in your neighborhood. This year, we plan to get to 15% of homes in Los Altos & Los Altos Hills without drought thirsty lawns. Look for more talks and information about easy things you can do to help conserve water and join the Governor’s 20% club. If you want to be part of the team, contact us.
Watts (all things energy related): Grow our installed solar base to 1500.
In the solar energy realm, we have a very specific goal: to cover 1500 Solar Roof tops in Los Altos and Los Altos Hills, up from the current number of 1297. With Electric Vehicles (EVs) as a beneficiary of solar, along with Community Choice Aggregation, and lower solar panel cost, now is the time for everyone to head closer to net zero energy use at home.
Look for more information in the coming months as we aim to be the greenest community in the State. If you want to be part of the team, contact us.
WoW: Increase involvement at every school.
Our third new initiative is in our WoW program. This year’s goal is strengthening our WoW program by identifying a PTA WOW volunteer at each public school in the Los Altos School District as well as Montclaire Elementary school. Currently 45% of the elementary and 70% of the middle school students, bike, walk, or roll (skateboard) to school each day.
In addition to local volunteers, we need a new bike/walk program chair, inspiring others to take action and assist Los Altos reach the bike friendly community silver level. If you want to make a difference and part of finding a solution, contact us.
Waste: Make compostables pervasive.
Our last initiative involves our Waste program. With the recent ban on Styrofoam, the goal is expanding our compostable program to community groups and our schools. The compostable co-op offers a 25% discount on World Centric products, a sustainable alternative to buying plastic materials that increase our landfills. Compostable materials provide a sustainable product to serve food at various events in and around town. With the public schools assistance, we are promoting awareness and process for sorting lunchtime waste. Educating students about the which items go into which waste bins increases the diversion to our landfills, both at school and home.
If you want to be part of the compostable revolution, contact us.
Whatever your interest, we appreciate your continued support and making a difference in our community which inspires action. I look forward to seeing you at one of our many events or program meetings.
When it comes to renewable energy, the politicians are always asking, “Is this stuff for real?” Dr. Dan Arvizu has the answer and he shared it with a packed house at the World Affairs Council talk in Los Altos, Jan. 7, 2015.
Yes, renewable energy is for real. We don’t have to invent anything, we have the technology today to make the grid work with 80% renewably sourced power.
That was the message Arvizu delivered, a positive one for receptive ears.
Through wind, biomass and solar, there can be enough power to reach the 80% goal by 2050 and with some tweaks to make the grid a smart system, it can be reliably distributed. We still need some breakthroughs in storage technology to get to 100%, a challenge for the future.
So why isn’t it happening? According to Arvizu, the political will isn’t there to stand up to cheap fossil fuels, except perhaps in California with the leadership of Gov. Brown. Dr. Arvizu met with Brown who made it clear he wants to cut the use of carbon in half, which is important, as public policy is what will create the change.
The top three nations generating renewably sourced power in 2012: China with 90 Gigawatts, US with 86, and Germany with 71. For both China and the US, over half was wind power, but for Germany over half was solar. And he pointed out that Germany is the same latitude as southern Alaska! The good news is that the US has over 40 Gigawatts of solar in the pipeline, so we are moving in the right direction.
The other part of NREL’s mission is efficiency. Half of the energy produced from burning fossil fuels is lost as waste heat. Cars are inefficient. Buildings are inefficient. Surprisingly given its location, NREL’s headquarters in Golden, Colorado is a net zero building with 1350 employees, constructed at less cost than a similarly sized building designed to standard code. So it can be done without exorbitant costs. He did mention that it takes some adaptation by the workers. No space heaters tucked under desks!
Several time he referred to a slide calling for a Profound Transformation to take us from today’s unsustainable energy system to a future system that is reliable, efficient, carbon neutral, secure and resilient. His point was that we need to make that transition now, not 30 years from now.
After the slide show he entertained Q&A. Some highlights:
What’s the latest on battery technology? This will be a profoundly disruptive and important technology, but getting the price down is difficult.
Where is photovoltaic heading? Costs are coming down and the goal of SunShot (an initiative of the Dept. of Energy) is $1/W but the big challenges are the soft costs, all of the paperwork and permit costs.
How do you get people to value a sustainable future? His answer was a bit vague, but some folks just approach things differently. He gave a couple of examples. In Singapore, you have to buy a 10 year permit to drive a car and it costs $100,000. The result? People take public transit. In Sweden, a car registration costs almost as much as the car. In the US, we value “rugged individualism” so none of that happens which means sustainability also takes individual choice to make it a reality.
What changes can we ask for at the local level? Again, his answer was a bit off target, but still interesting. He told us about 5 utilities getting together to plan for future changes. This was notable in that they would even get together, and even more notable in that they would share confidential data. He was there so he saw it!
How will the grid work in the future? He had a lengthy talk about the distribution pipeline and the direction of energy flow, but finally settled on an interesting story. NREL is studying the impact of using car batteries to smooth out the energy flow in the pipeline. Toyota is asking should we build electric cars to supply energy during peak demand using cars that are parked, and the power companies are asking what will happen to the grid if car batteries are supplying power during peak demand? Hmmm, makes one wonder if NREL is getting funded by both sides for the same question?
Why didn’t you mention nuclear as an energy option? It’s in the mix, but they need to be held to the same high sustainability standards as all the other sources, and that is a problem for nuclear.
Final thought, renewable energy and energy efficiency make so much sense, let’s do it!
