The Solar Thermal Renewable Option for California:
Commitment to Addressing the Global Warming Crisis by 2020

Under a solar-thermal scenario to address the global warming crisis (including enacting a
strong emissions cap), solar electricity generated in California could rise from .02% in 2006 to
9% in 2020.

Under nationwide “Business as Usual” projections, coal will be used to meet 57% of America’s
electricity needs in 2030. In contrast, under a solar-thermal scenario, California’s proportion of
coal-generated electricity could fall to only 2% in 2020.

Type                       Percentage
Natural Gas                 35%
Nuclear                     8%
Large Hydro                 17%
Small Hydro                 2%

Geothermal                  5%
Biomass                     8%
Solar                       9%
IGCC*                       2%
*IGCC refers coal steam reprocessing. It produces a slightly lower emission rate.

Using Carbon Emissions Cap




The graph was calculated based on a policy scenario that would set an annual emissions cap as its
constraint. It is based on the Governor’s targets to reach 2000 carbon emissions levels by 2010
and 1990 levels by 2020.

The foregoing projection was constructed using Sara Kamin’s A Comparative Analysis of Global Warming Policies for California’s
Electricity Sector, which was submitted to fulfill the requirements for the degree of Master of Science in the Energy and Resources
Group of the University of California, Berkeley. It was submitted to Dr. Alex Farrell and Dr. Daniel Kammen. Currently, Kamin
works as a policy analyst the California Public Utilities Commission.
