The World is Warming
Source: Summary for Policy Makers, Climate Change 2001: The Scientific Basis, p. 3
“The rate and duration of warming of the 20th century has been much greater than in any of the previous nine centuries.
“Similarly it is likely that the 1990s have been the warmest decade and 1998 the warmest year of the millennium.”

Legislative Requirements of the RPSSenate Bill 1078 (SB 1078) requires that the following
goals are achieved:– Retail electricity sellers must increase the renewable
content of their energy deliveries by at least 1 percent of retail sales per year over 2001 baseline
– Annual incremental increase must continue until renewables comprise 20 percent of each retail seller’s energy portfolio by December 31, 2017.

Accelerated RPS Goals Gov. Schwarzenegger called for accelerating the
RPS phase-in to 2010, rather than 2017. 2003 Energy Action Plan accelerated RPS goal
to year 2010.– California Energy Commission– California Public Utilities Commission– California Power Authority
2003 Integrated Energy Policy Report– Underscored Energy Commission’s support for
accelerated goal– Recommended more ambitious, longer-term goal for
post 2010
