Since the early 1990s, according to data gathered by Massoud Amin, an electrical engineering professor at the University of Minnesota, the number of power outages affecting more than 50,000 people a year has more than doubled, and blackouts now drain between $80 billion and $188 billion from the U.S. economy every year. The power grid is slipping backwards to a time when infrastructure was unreliable, and more and more people are talking about going off the grid with solar, batteries, and generators as a result. Will this doom the greater grid, and by extension the greater good?
Its not easy to keep 450,000 miles of high voltage lines up and humming. But the situation has gotten worse over the years because the U.S. has increased the load on its lines while investing less in the system. By Amins reckoning, since 1995 the power industry has taken more from its infrastructure than its invested; research-and-development spending in the power sector has fallen to just 0.17 percent of revenue. In effect, the power industry has behaved like a low-tech industryand so its becoming one.
Across the power and wonkish sectors, though, theres a fair amount of agreement that the U.S. needs to make massive investments in the backbone of the grid, as well as in a self-healing grid that can better handle outages (and hackers), and in information technology to make the grid smart. Amin estimates this will cost $17 billion to $24 billion over the next 20 years, but will save perhaps $49 billion in outage costs per year and increase energy efficiency to save another $20 billion a year. In other words, as a nation the U.S. would almost make money on the spending.
