Will Public Power Save the Day?

And there is a distinct possibility that much of this generation will be smaller units distributed across the grid, as opposed to the large, central-station generation that has been a mainstay of the utility industry to this point in its history. Because of steady declines in cost of production of solar cells, such distributed solar units are reaching “grid parity” — that is, costs are at or below the costs of retail electricity — in the most expensive states. If the trend continues as predicted, grid parity could be achieved across the country by the mid-2020s, even without subsidies or favorable tax treatment. This interactive map illustrates the possibilities.
