Our speakers are taking a break and so now is the time to give everybody the opportunity to discuss, debate, and get educated on all the green and clean issues that we are faced with today. In our September 21, 2017 meeting, we are going to start off by addressing the CA WaterFix/Delta Tunnels Project. Where we go from there depends on what else people want to talk about. Join us and leave our meeting well informed and with an itch to do something about some of the problems we are facing! Read More

The Sweet Commute
We all feel it. We are all impacted by it. We all hate it. I am talking about our Santa Clara Valley traffic and transportation infrastructure. What can we do to improve the situation? Beverly Turner is going to guide us through an interactive session where we attempt to come up with ideas to resolve these issues. Bring your brains, bring your laptops, and we will see if we can come up with some creative ideas to get the attention of those who manage our transportation infrastructure. The date is September 7, 2017. Read More

The advent of motor vehicles ushered in a new wave of productivity for humankind. It created economics of scale never or known seen before. Unfortunately, it also silently started to hurt the very environment that we live in. Increasing carbon emissions around the world have created irrecoverable damage on Mother Earth. New inventions like the electric cars are slowly but steadily helping stop and in some cases, reverse the damage being done but still a lot more still needs to be done.
We have to change and optimize the way we drive, lower the number of miles driven on a daily basis and adopt technologies to develop efficient least travel patterns, improve gas mileage, and predict breakdowns. The connected cars of today can help us achieve these goals – by the simple OBDII diagnostic outlet. Big Data technologies can help us take all these data and churn it into information that can be used by individuals and businesses alike. This talk will showcase with a live demo of how today’s connected cars are driving humankind towards greener pastures. General aspects of Big Data and way and means by which it can be harnessed for various applications in the Energy domain will be covered.

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.

One of the miracles of the modern era is the reliability of the power grid. An understanding of how a utility operates will not only allow a better understanding of how the electricity we use daily is generated and transported to our homes and businesses, but will provide insight into how alternative technologies such as Smart Grids and Demand Response will change the way we think of power generation, transmission, and distribution.
How does a utility transmit and distribute electricity?
How is the electric power generated?
What is Demand Response?
How is deregulation related to utility markets?
Who is the CAISO and what function does it perform?
What is a Smart Meter and how does it relate to the Smart Grid?
What is the Renewable Portfolio Standard?
What technologies will have the greatest impact going forward? Come join us for this special EcoGreen Group meeting.
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.”

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.
A very important meeting took place on 08/22/17 at the Almaden Expressway site of the SCVWD.
