BOOK REVIEW — Powering Through is a worrying and detailed examination on the vulnerability of our electrical grids, written by experts who know what they are talking about. Their mission statement sums up the what and why. ‘The InfraGard National Disaster Resilience Council Mission is to inform communities how to mitigate the high-impact threat of long-term power and communications failure (greater than 30 days), which could lead to catastrophic, cascading losses of life-sustaining infrastructures and resources for recovery.’ The recent crisis in Texas is evidence that much more work needs to be done to make us safe. Lack of investment by power companies coupled with weak regulation and the change in modern warfare toward weapons such as cyber and electromagnetic pulse make this a compelling read. The primary target now in any major conflict would be the destruction of your enemy’s electrical grid. Here is an accessible guide to one of the biggest threats facing us today.
