This is my second time in the EJ. The first time was in 1998, for my research for the Energy Center of Wisconsin on green power marketing.
If you are not a subscriber to EJ you can also read it on the Power Markets website.
You can also listen to and watch the "audio slide" presentation that I did for the Electricity Journal website. Just click below. It is a shorter version of the talk I gave at the NARUC conference.
