The Electrical Grid in Flux
What are the operational and economic limitations to installing alternative generation technologies, such as solar, wind, geothermal, and nuclear? What are the political and social constraints? And how do large-scale storage technologies and data centers affect the needs of the electric grid?
Energy engineer Dave Walter will explore the past and present of integrating renewable energy into our electricity delivery system. He’ll look at the difference between traditional forms of generation, like coal and natural gas, and alternative sources through the “levelized cost of electricity,” that is, the average total cost of building and operating an energy system over its lifetime, divided by the total energy output produced during that period. And beyond technical considerations, Walter will examine how public policy at the state and federal level is challenging and abetting the installation of alternative energy sources.
