<prompt> Human: I am a mid-20s homeowner in the midwest and I get mail and the occasional door to door person trying to get me to sign up or opt in for changes in my electric and gas companies several times per year. Often the mail references price locks for a couple years which seem to promise that I will have lower monthly bills than what i have in my current arrangement. Unfortunately, I have no frame of reference for what my energy costs are currently aside from I signed up for the same monthly bill every month on my electric and gas regardless of usage this is to avoid crazy bill changes during different seasons so my budget remains predictable. These get adjusted once per year but they have been pretty stable.Last bit of background - a few years back a court case between 2 electic companies ended and I was switched companies without realizing it and my bill was crazy. When I called and asked about it, it was explained that I had a ton of fees now because the company that owned my power lines, didnt actually generate my power anymore. Trying to avoid such fees happening again is why Ive never responded to these mailings or door to door people.How can I consider these mailings wisely and what fees should I be on the look out for?  <response>: In my personal experience, if someone comes to your door trying to sell you shit, it is never the best option.
