Idaho is listed among by the U.S. Energy Information Administration among the ten states where energy prices are the lowest. Writes Sam Becker of the Wall Street Cheat Sheet: "The folks in Idaho are fortunate to live next to a prime resource for energy: the Snake River and its tributaries. There are 17 hydroelectric power plants that use the river to generate electricity, providing over 1.7 million kilowatts of energy to Idaho residents. With the help of all of that hydroelectric infrastructure, the EIA’s numbers indicate Idaho spends $19.87 for every one million BTU. As of 2013, 78 percent of the state’s electricity generation saw its genesis in renewable sources, and also had the fourth lowest average electricity prices in the entire country." More here.
