Analysis of California Electricity Consumption

Project Description

One of the most important lessons of the past 30 years of energy policy is that analyzing how people use energy, and how that use changes over time, can yield important policy insights. Yet this lesson has largely been ignored in the popular discussion of the California electricity crisis. To help fill this information gap, this project is compiling a general overview of electricity consumption and peak load in California. We have examined the growth in electricity demand over the last twenty years, as well as the current composition of electricity end-uses. Much of this work is based on data compiled by the California Energy Commission, supplemented by various other agencies such as the California Independent System Operator and the Federal Energy Regulatory Commission.
