Renewable sources of energy are gaining an increasing share of the US energy mix, bolstered by state-level commitments as well as corporate power purchase agreements. However, while renewables have become increasingly cost competitive, they still face challenges, especially related to intermittency and storage.
The Global Energy Center’s new issue brief, “Ensuring Energy Security in a Renewables World,” by Ben Hertz-Shargel explores the energy security implications of greater integration of renewables into the grid. The issue brief looks at intermittence and the need for flexible capacity, grid stability, long-distance transmission, and cybersecurity. Hertz-Shargel also examines the episodes of wildfires and extreme weather in the summer of 2020 and the affects of extreme weather events on a decarbonized grid system.
