Usually, fixed-rate renewable-energy plans are among the most expensive options. But in our research, we found Constellation’s green plan rates were comparable to its non-green versions. For example, out of two otherwise identical fixed-rate, 12-month plans from Constellation — “12 Month Fixed Rate 100% Green” and “12 Month Fixed Rate” — it’s the renewable version that currently costs less.

Although electricity had been known to be produced as a result of the chemical reactions that take place in an electrolytic cell since Alessandro Volta developed the voltaic pile in 1800, its production by this means was, and still is, expensive. In 1831, Michael Faraday devised a machine that generated electricity from rotary motion, but it took almost 50 years for the technology to reach a commercially viable stage. In 1878, in the United States, Thomas Edison developed and sold a commercially viable replacement for gas lighting and heating using locally generated and distributed direct current electricity.


Several states have Community Choice Aggregation (CCA) laws that allow local governments to pool their community’s electricity need in order to purchase power on their behalf.  While savings is not always guaranteed, many municipalities are able to obtain discounted electricity prices. You’ll have to check with your state regulatory commission. You can get started by clicking on your state in this map.
