Retail Electricity Prices, Relative To National Average

In the early days of electricity, it was difficult to transmit electricity long distances. So it made sense to build power plants close to population centers and transport fuel over these great distances via rail or barge. Over time it got cheaper to transmit electricity, but the regulatory framework has been slow to catch up and largely continues to treat power generation as a local issue.
Twenty-five counties in just a handful of states produce two-thirds of our nation’s coal and then ship it to power plants all throughout the country. The farther away a plant is from a mine, the greater the coal—and with it, electricity—costs. It costs nearly five times more to buy coal in Maine than in Wyoming.
Much like coal, wind and solar resources are distributed unevenly throughout the country. Unlike coal, one can’t put the wind or sun on a rail car. Without a transmission network to import electricity from renewables-rich regions, solar and wind resources aren’t being put to good use.
