Does Anyone See A Problem With This Picture?
Sundarbans Region
To find this story, Google "Sundarbans Refugee Camp"
Two Energy Agencies in California
• The California Public Utilities Commission (CPUC) was formed in 1890 to regulate natural monopolies, like railroads, and later electric and gas utilities.• The California Energy Commission (CEC) was formed in 1974 to regulate the environmental side of energy production and use. • Now the two agencies work very closely, particularly to delay climate change. • The Investor-Owned Utilities, under the guidance of the CPUC, spend “Public Goods Charge” money (rate-payer money) to do everything they can that is cost effective to beat existing standards. • The Publicly Owned utilities (20% of the power), under loose supervision by the CEC, do the same.

How Much of The Savings Come from Efficiency
• Some examples of estimated savings in 2006 based on 1974 efficiencies minus 2006 efficiencies
• Beginning in 2007 in California, reduction of “vampire” or stand-by losses– This will save $10 Billion when finally implemented, nation-
wide
• Out of a total $700 Billion, a crude summary is that 1/3 is structural, 1/3 is from transportation, and 1/3 from buildings and industry.

California’s Energy Action Plan
• California’s Energy Agencies first adopted an Energy Action Plan in 2003. Central to this is the State’s preferred “Loading Order” for resource expansion.
• 1. Energy efficiency and Demand Response• 2. Renewable Generation• 3. Increased development of affordable & reliable conventional
generation• 4. Transmission expansion to support all of California’s energy
goals.
• The Energy Action Plan has been updated since 2003 and provides overall policy direction to the various state agencies involved with the energy sectors
