What Super Volcanoes Have To Do With Electric Vehicles
Most of our high technology developments includes the use of some type of rare earth elements. This is a big problem since these rare earth elements are not distributed uniformly around the world. Where do we find these elements? In the 04/26/18 EcoGreen Group meeting, we will take a look at this issue and look specifically at the relationship of super volcanoes and electric vehicles. Join us to find out what this relationship is! Read More
Total Native Bee Experience

Soil Health for Carbon Sequestration in the Face of Climate Change
Soil; it gets your carpets dirty, the dog tracks it into the house, but, let's look at it's benefits. Good soil is very important. It serves us well. It is our primary medium for growing our food crops. It provides a symbiotic playground for all of life on the earth. And, it can be used to sequester carbon from our atmosphere to offset climate warming. In our April 12, 2018 EGG session, Elizabeth Guimarin will provide us the latest interesting updates on the benefits of good soil. Please join us! Read More
Urban Smart & Green Views
Our cities are going to have to change to allow for sustainable living in the future. What will they look like? How will they be different? What decisions issues will have to deal with? How reved' up on technology will they be? Join us at our 3/22/18 EcoGreen Group meeting for an exploration of this topic. We will view some videos and have some discussion. Read More

Our investment choices can have a broad impact socially and environmentally. Financial Advisor Toby Cooper will explore the origins, development, and benefits of “socially responsible” (aka, sustainable, ethical, or green) investing, including a nod to 18th Century Quakers, Dr. Martin Luther King, and anti-war activists of the Vietnam war era. He will discuss how investors can achieve their financial goals while aligning their invested dollars with their inner values. He will demonstrate how sustainable investing has found its place in the mainstream investor landscape today. Finally, he will discuss how sustainable investment decisions will interface with “2015 Year-Ahead” investment forecasts from leading Wall Street analysts.
Come join us for an interesting evening and explore how your investment choices can make a difference.
Rainsavers recently completed a job in Mountain View, California whose owner built a home that uses very little municipal water and has native Santa Clara County plants, grasses and fruit trees. Rainsavers installs rain barrels, tanks and complete systems for residential, commercial and public facilities.
The homeowner built the home with a grey water recycling system, sheet metal roofing material, a solar hot water heating system, a “wetland” leach field where the grey water is diverted and a Rain Water harvesting system.
The owner also had a nine thousand gallon underground cistern installed as the home was built to store the rainwater from the roof. One of the goals and mandates coming from state and local governments is to greatly reduce runoff from around the bay area. All the gutter downspouts are routed to the tank. The water collected is tied to her drip irrigation system and used on the landscape. The tank overflow is directed to a rain garden where the water seeps back into the ground.
Rainsavers was hired to install the pump, pressure tank, electronic valves, controller, PVC conduits and electrical supply for the system on her property.
The first picture shows the smooth concrete siding, the metal roof, manhole access to the tank and the wetland field on the left side.
The drip system can be automatically switched from municipal water to the rain water system depending on storage levels, via a three-way electronic control valve.
The second picture shows the pump, pressure tank, controller and electric panel. A pressure tank has 20-40 pounds of air pressure to prevent the pump from cycling on/off as the systems is used. The controller monitors the water level in the tank, and it can activate system flush, backup, transfers, drain and service reminders.
Behind every advancement in the areas of renewable energy and energy management, are some underlying technologies which help make those advancements possible. The IEEE 1588 Precision Time Protocol is one of those underlying technologies which is helping to make the Smart Grid a reality. This presentation will provide an overview of this technology and some of its uses in the Smart Grid.
Saratoga Federated Church, Richards Hall 20390 Park Place, Saratoga, CA 95070 Enter on west side, corner of Oak Place and Saratoga-Los Gatos Rd (Hiway 9).
About the Presenter Rod Kirk, a San Francisco Bay area native, has held various Electrical Engineering positions in numerous companies in the areas of data storage, networks, and motion control. He has a degree from San Jose State University and an Energy Management certificate from De Anza College. Rod is currently providing Technical Writing services for emerging companies.
Heidi will share information about the Green Tech Academy, and how this organization has helped people prepare for and land jobs in sustainability. The presentation will be followed by an interactive session on how EcoGreen Group members and the Green Tech Academy can work together to find volunteer opportunities in their own areas of interest. The Green Tech Academy (GTA) offers a unique training experience geared towards individuals who are interested in re-engineering their professional careers and learning more about the opportunities in the rapidly growing clean tech industry. GTA's industry experts provide participants with the knowledge, resources and support to transition into the thriving clean tech sector.
On November 13, 2012, MIT/Stanford Venture Lab (VLAB) sponsored “Grid Energy Storage: Beyond Batteries”, a panel event to discuss grid-scale energy storage. After treating the audience of about 300 investors, entrepreneurs, technologists and thought leaders to a short harmonica solo, Eric Wesoff from Greentech Media proceeded to outline the landscape around grid-scale energy storage and moderate the panel around future directions in grid-scale energy storage.

Wesoff overviewed current technologies, the complicated value chain which generates and delivers energy to end users, the cleantech investment climate, and the environmental /government mandated need for clean, renewable energy which can only be enabled by grid-scale energy storage.
Currently, grid scale energy storage is dominated by pumped hydro. “For grid applications, it’s all about cost per kilowatt hour” said, Abe Yokell, panelist and Partner at Rockport Capital Partners who foresees grid-scale energy storage for certain, specific use cases such as where local energy storage in dense urban environments is less expensive than running in new utility lines. Philip Gleckman, CTO of Areva Solar agreed “Grid Storage with batteries is not inevitable…Thermal storage is available costing one tenth of the best battery technology. Justin Raade, CEO of Halotechnics, Inc described how his company is working on grid-scale thermal storage as low as $25/kw-hr.
Indeed, two grid-scale energy storage companies were represented on the panel. Lightsail Energy of Berkeley, CA and Aquion Energy of Pittsburgh, PA shared their experiences as start-ups entering a heavily regulated, highly fractioned, risk averse environment.

Rounding out the panel was Haresh Kamath, Sr. Project Manager for EPRI. “While American utilities are greatly incented to “KTLO – Keep the Lights On” which has led to risk averse investing, Kamath & Rastler have described 10 specific business cases for grid-scale energy storage which have attracted attention from the venture capital and investment community. Kamath noted that for certain off-grid applications, the newer energy storage technologies, when paired with solar, have the potential to “leapfrog” the current grid which many have observed to be little changed over the past 100 years.
Mike Lee, Financial Advisor, on why Morgan Stanley sponsored the panel, “We like sponsoring these sorts of events in order to bring people together to facilitate growth in this community.” Another perspective was offered by Laurie Manning, volunteer with the MIT/Stanford Venture Lab “We have to look beyond our current economic crisis to greater environmental issues. Superstorm Sandy showed this. We need greater urgency before it’s too late.”
