California's Energy Future Study: Portraits of the energy system in 2050

Jane Long
Principal Associate Director at Large
Lawrence Livermore National Laboratory

Abstract
The California Council on Science and Technology has undertaken a study of California's energy system in 2050. By executive order, the state is to reduce emissions to 80% below 1990 levels by 2050. The study identifies energy system descriptions (called "portraits") from a technical perspective that would meet this standard and allow for population and economic growth. The requirement for growth means that the energy system should have nearly zero emissions. The portraits are constructed by evaluating four key questions: How much can we control demand? How much heat and transportation will be electrified? How will electricity be de-carbonized? How much sustainable biofuel could be available? Results show an energy system that dramatically different than today, but largely relies on technology we know about.
