An example of Clean Energy marching forward:
Renewable Energy Systems Americas Inc., better known as RES Americas, said Tuesday it will build two of the largest commercial-sized energy storage projects in North America.
RES, a wind farm developer based in Broomfield, Colorado, said the two projects will be built outside of Chicago, and once completed in 2015, will be capable of storing a total of 19.8 megawatts of power to support the local Commonwealth Edison (ComEd) electricity grid.
These batteries will be on line, or should I say, inserted into the back of Chicago behind a giant plastic plate held in by a huge screw (I assume). by August 2015, and they will operate for ten years.
