Tony Seba was among the first to recognize the disruptive potential of solar PV with the publication of his book “Solar Trillions” in 2010. His think tank, RethinkX, recently published a report titled “Rethinking Energy 2020-2030 – 100% Solar, Wind and Batteries is Just the Beginning.” In early December, pv magazine publisher, Eckhart Gouras, interviewed Seba and Adam Dorr, the two authors of this report. As Seba and Dorr make clear in the interview, a 100% solar-wind-battery system is not only possible, but the cheapest way to build an electricity system in the U.S. by 2030. They introduce the concept of the “Clean Energy U-curve,” which shows that the cheapest system is actually one that involves a lot more solar PV and wind power capacity than the peak power demand profile. But they go one step further by introducing the concept of “SuperPower”: by investing in even more solar PV and wind power than the lowest-cost system defined by the “Clean Energy U-curve,” the gain in additional energy, or “superpower,” is exponential to the money invested.
