There’s nothing to give you a little perspective on what’s happening on planet Earth like getting off it and seeing its beauty—and it’s human-caused destruction—from space. In this wide-ranging interview, former astronaut Jay Apt, a professor of technology and business at Carnegie Mellon University, shares some insights from his voluminous body of research on energy transition topics, including: what the power grid of the future could look like; how we’ll balance it with increasing levels of renewable energy; how to smooth out the fluctuations in wind farm power output; utility business model evolution and resource adequacy planning; what the optimal amount of storage on the PJM Interconnection might be; the economics of behind-the-meter battery systems; the potential future for EVs providing services to the grid; whether carbon capture and sequestration technology and geoengineering can play significant roles in addressing climate change; the new era of electricity de- and re-regulation; and of course, what it’s like to look down on Earth from space. You’ll never see an hour go by as quickly as this one.
