Recent power outages in Michigan, New York and San Francisco are the latest evidence of how bad weather and antiquated equipment shut down vital energy services. A government study estimates that weather, the most common cause of power interruptions, costs the national economy tens of billions of dollars every year. Four months ago, the U.S. Department of Energy warned that the electric grid is in imminent danger from cyberattacks. Last month, a report from MIT recommended federal tax incentives for the owners of gas pipelines and the electric grid to protect them from cyberattack. Another portion of new revenues could help Americans improve the energy efficiency of their homes, businesses and transportation choices so that savings on energy bills help offset any increase in consumer prices.
