Where Chicago gets its power

ComEd sent out its annual Environmental Disclosure Statement last week detailing where the electricity that supplies Chicago has come from.  50% nuclear, 38% coal, 9% natural gas, and then all the others--not a very pretty picture. 

Leaving all the operational safety and environmental impact considerations for our major electricity sources aside, it's just not a great idea to have so much of generation capacity confined to such a small number of sources.  Maybe one of the best arguments for growing a distributed generation network of small solar systems is the redundancy it provides us all.  Even those of us in a neighborhood who don't have a solar system on our own roof benefit from the system on our neighbor's roof. 

So what's the trigger that will get us started on this better path?
