Energy Self-Reliant States 2020: Third Edition

By Maria McCoy and John Farrell - Institute for Local Self-Reliance, September 2020

If each U.S. state took full advantage of its renewable resources, how much electricity would it produce? How much of its own electricity consumption could renewable energy fulfill? Would in-state renewable generation be enough to charge electric vehicles and power electric heating, too? In 2010, ILSR published the first national overview of state renewable electricity potential with the second edition of Energy Self-Reliant States (ESRS). At the time, most states were setting ambitious goals to attain 25 percent renewable electricity.

Now, several states and over 100 U.S. cities have made truly ambitious commitments to 100 percent renewable power. Fortunately, this third edition finds a better technical outlook and a brighter economic picture than a decade ago. States have much better renewable energy resources than they thought. Also, the costs of renewable electricity sources, like wind and solar, have declined precipitously. The 20-year average cost (often called the “levelized cost”) of solar electricity has declined from around $0.200 per kilowatt-hour for small scale projects to $0.091 per kilowatt-hour. The decline is even more dramatic for utility-scale solar, with the levelized cost falling from $0.120 to about $0.037 per kilowatt-hour. Wind energy costs have declined by significant margins, as well, from around $0.13 to $0.04 per kilowatt-hour.

Clean energy is not only affordable, it is a big contributor to the U.S. economy. At the start of 2020, the clean energy industry employed 3.3 million people – that’s 40 percent of America’s energy workforce. The clean energy sector is strong and growing stronger; the U.S. Bureau of Labor Statistics predicts that solar installers and wind technicians will be the fastest growing occupations in the next decade.
