Are We Going To Cope With Ocean Acidification? PDF Print E-mail
Written by Rod Kirk   

A Presentation By Dr. Robert Greene

This presentation recognizes that ocean acidification is an imminent threat to sea life, and indeed, our entire lives.  If we take a ‘business as usual’ approach, we may be too late in saving the oceans for our children and grandchildren.


Bob Greene picFirst we will look at ocean acidification and its effects.  Then we will discuss the Carbon Cycle, i.e. how and how much generated CO2 is naturally stored in the atmosphere, gradually dissolved in the oceans, changing their chemistry (pH), and gradually sequestered on the ocean floor.  An analogy will be drawn with how the Oregon oyster farmers faced this issue but on a smaller scale.  Then, a first order estimate will be made as to how much energy will be needed to address this issue over what period of time.

Next we will posit “Where will we get this massive amount of carbon-free energy?”  To answer this, we will look at global energy demand through mid-century and what the contribution must be from each clean energy source to meet each share of this requirement.  Solar and wind alone will probably not meet this need.  Dr. Greene will review other energy sources, including ‘new nuclear’ and how they can make a major improvement in this picture.

Grey Water Systems PDF Print E-mail
Written by Tony Green   

 Presented by Tony Green

“Grey Water Systems: What they are, why their time has come and how you can participate in conserving our most precious resource”.


Tony Green Picture 050715The recent drought has prompted Governor Brown to enact mandatory water restrictions for the first time in the history of the state of California. With no end to the drought in sight and the level of the state’s reservoirs being at their lowest levels in decades, everyone will need to take steps to conserve this precious resource. Grey Water systems have recently been proposed as a method where home owners can help conserve water by using reclaimed water produced by laundry, sinks and bathtubs in non-potable applications such as irrigation or flushing toilets.  



I will cover questions such as:

  • What are Grey Water Systems and what are the benefits of their use?
  • Why are Grey Water systems becoming part of the water conservation
  • What are the concerns of using Grey Water?
  • Will I need a permit to install a Grey Water System?
  • If I wanted to install a Grey Water System how would I go about it?
  • What products are safe to use with a Grey Water System?
  • What components comprise a Grey Water System?


Come join us for this special EcoGreen Group meeting!

Big Data Use Cases for Energy: Connected Cars - Driving Humankind Towards Greener Pastures PDF Print E-mail
Written by Rod Kirk

 Presented by Dj Das

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.


Please join us for this special EcoGreen Group presentation event.


Attendance at this event is Free. However, we would appreciate attendees to sign up for the event at the Eventbrite site. Additional info and driving info is available at our Meetup site, as well as below.

New Directions for U.S Water Policy PDF Print E-mail
Written by Mei-Ling Shek   


A Roundtable & Video
Hosted by Mei_Ling Shek
Water is critical to America's social, economic, and ecological well-being. Yet, more than 70 percent of the western United States is in the grip of an ongoing drought that shows no signs of ending. The water crisis is as much an economic issue as an environmental one, and demands focused national attention. On Oct. 20, 2014, the Hamilton Project at Brookings and the Stanford Woods Institute for the Environment hosted a forum “New Directions for U.S. Water Policy”, which highlights the challenges and opportunities for improving water management in the face of water scarcity. We shall focus on the recorded roundtable discussion “The Path to Water Innovation”, in which Buz Thompson of Stanford University presented the main findings of a white paper he co-authored. We shall have a short discussion after viewing the video.
