Microgrids – The Future of Electricity

1

Rocky Mountain Institute (RMI) visited the University of California, San Diego, to document the campus microgrid.

According to the video description:

At UCSD, the microgrid provides the ability to manage 42 megawatts of generating capacity, including a central cogeneration plant, an array of solar photovoltaic installations and a fuel cell that operates on natural gas reclaimed from a landfill site. The central microgrid control allows operators to manage the diverse portfolio of energy generation and storage resources on the campus to minimize costs. In addition, the campus can “island” from the larger grid to maintain power supply in an emergency, as in the case of the power blackout that struck parts of Southern California, Arizona and Mexico in September 2011.

San Francisco Finds a New Landfill?

By 2015, San Francisco officials are hoping to send waste to a landfill in Yuba County, near the town of Wheatland, CA.

According to the San Francisco Chronicle, the garbage will be taken by truck to Oakland, loaded onto trains, and shipped 130 miles to a 236-acre landfill.

The city is currently under contract to ship garbage to the Altamont Landfill in Livermore.

The proposed landfill in Yuba County is owned by Recology (formerly Norcal Waste Systems) and currently receives about 750 tons of trash each day. It is expected that San Francisco would send more than 1000 additional tons of trash to the landfill each day.

Details of the plan are still being negotiated, and the San Francisco Board of Supervisors will have to approve any final proposal.

On a side note, Recology has a blog with lots of info about waste and recycling in the Bay Area. I’ve just started reading through some of the archives.
