What: Reduce CO2 using
Kyoto Protocol standards
Japan, Canada, EU implementing
How: Implement best
energy use practices
Credo clause
ALZA’s LFG Project
is a best practice
4
CO2 Reduction Goals
 Kyoto Protocol
–1990 is base year
–4% reduction in 2005, 7% in 2010
 ALZA needs to reduce
–22.3 million pounds per year CO2
–75% reduction from 2006 levels
 ALZA demand
–4 to 5 mW average
–7 to 8 mW peak
5
Energy Management Best Practices
 Ten stages
 245 separate action items
 5 to 10 year implementation, but ALZA got 3.5
 ALZA is 100% done
6
Evaluation of alternatives
Pathway
Potential Benefit
Conservation
Full implemented, but only
saves about 10%
Cogeneration
Inadequate demand for waste
heat
Renewable fuels
Evaluate (look close if located
next to landfill)
Clean Power
Weak economics
ALZA lacks roof space
Carbon trading and
sequestration
7
Can buy 100% of CO2
reduction goal for less than
$15,000 per year
Landfill Gas (LFG) Summary
 Composition: CO2 and CH4, 50:50
 Uncontrollable byproduct of anaerobic
digestion of trash
 Combustible greenhouse gas
– Capture and burning is the standard control method
 Renewable energy source
– PG&E has self generation incentive program (SGIP)
grants for renewables
 Established technology
– 300+ LFG projects in US currently in operation
– US EPA Landfill Methane Outreach Program (LMOP)

ALZA Project Summary
 Scope
– Build pipeline to transport landfill gas from golf
course to M1/M5, M3, and ALZA Plaza
– Install three - 1 mW engines, fuel them with landfill
gas, produce electricity and hot water (enough to
power 1,500 homes)
 Project
– Completion: June 2006
– Life: 15 years+
 Investment Summary
– Total Cost
– PG&E Grant
– Net investment
