I think it was you that mentioned that your utilities use gas to generate electricity. They use NG of course which is very different than "gas" which most people use to mean gasoline. Shockingly different products.
The wholesale cost of electricity runs between 2-4 cents a kwh. There has to be profit and distribution costs but anything over 15 cents at the retail level is either to encourage conservation, poor decision making on peak issues, or excessive local costs/taxes. In CA - all of these are issues. LI - probably all except encouraging conservation.
I lived near Shoreham (PJ) as a child/teen. It was finished about 30 years ago and you are still paying for it? My single mom (and where she met her second husband) worked there so thanks for paying for my upbringing.
Strange how there are so many people from LI who live down here now.... Most of the time, I can get to Manhattan just as fast as you can.
