Saving money under deregulation /w ESCOs (Energy Service Company)
ESCOs have been providing gas and electricity supply here in New York for the past decade, since major deregulation. Obviously deregulation is happening at different rates in many parts of the US. There's a ton of options available, and a maze of information, making it difficult knowing who to trust.
The easy part is understanding how much money is saved in reducing energy delivery costs, which can be as much as 50-60% of the bill. Of course, not paying tax on your gas and electricity brings an immediate savings. Anyone have any precautions, considerations, positives/negatives, and general experiences on choosing the right ESCO, and the amount of savings realized over a period of time?
