Here are my 2 cents about electric companies when shopping around for the best rates. Currently, the average cents/kWh in Houston is 10 cents, after speaking to a very helpful, very informative Green Mountain Energy representative. Although their rates are a little higher than my current rates, they have FANTASTIC customer service (which is almost worth it). The GME rep even recommended that I stick with what I am using now since it's cheaper.

On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for. You’ll have peace-of-mind. If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
