100 % sustainable?

San Francisco has set its sights on becoming the greenest city in the country by turning 100% sustainable by 2020.

Announced at the completion of the Sunset Reservoir Solar Project, the project which is the largest municipal solar facility in the state, and covers an area said to be the size of 12 football fields the mayor announced a $250,000 grant from the Sidney Frank Foundation to assess how to meet the city’s 950-megawatt peak power demand with nothing but renewables by 2020. (While the plant has tripled the amount of solar energy made available to the state.)

San Francisco already has an impressive renewable record, including 10 MW of distributed solar and 3.5 MW of biogas. Firstly the state is expected to increase the amount of wave-derived energy from 30 MW to 100 MW, with local officials set to launch a 1 MW to 3 MW wave pilot project next year.

San Francisco has also signed into effect the nation’s first law mandating that all residents and businesses separate their recycling and compost material from normal trash. While many other cities in the US require recycling, no other city requires separation of food scraps and foot material to be composted. The measure, which will take effect this fall, is intended to help increase landfill diversion rates to 75% by 2010 as well as reduce greenhouse gas emissions.

We surely need more such role models.
