Palo Alto Green Energy PresentationPresentation Transcript
Enough green energy to power 1,400 homes.
Reduces greenhouse gases by 20,000 tons/year.
Saves Palo Alto $1,000,000 per year.
Energy available during power outages.
Palo Alto’s Dump Will Close Soon
Our Composting Operation would Cease Palo Alto’s yard waste would get trucked to Gilroy, generating 1,200 tons of carbon dioxide per year.
The Z-Best Composting Facility near Gilroy is 53 miles from Palo Alto.
Local Threats from Climate Change
Palo Alto Should Be Concerned about Climate Change Without levee improvements, much of Palo Alto would be under-water in the not-too-distant future.
The First Rule for Getting Out of a Hole is to Stop Digging
Palo Alto’s Climate Protection Efforts
Climate Protection Plan
15% CO2 reduction by 2020
33% renewable energy by 2015
Community Environmental Action Partnership (CEAP)
Zero Waste Initiative
73% diversion by 2011
90% diversion by 2021
Green Building Ordinance
LEED Silver for commercial
70 Build it Green (BIG) points for residential
Palo Alto Established a Blue Ribbon Task Force on Composting
The BRTF recommended anaerobic digestion, a process using microorganisms in enclosed vessels to break down organic waste into methane and compost.
Three Sources of Organic Waste 60,000 Tons Per Year Composition of Disposed Organics
Each Year Palo Alto’s Organics could Fill a Football Field the Height of City Hall 130,000 Cubic Yards
Palo Alto Has One of Only Two Sewage Sludge Incinerators in CA
6,000 tons of CO2 produced per year.
$800,000 worth of energy used in 2009.
$234,000 paid to dispose of waste ash.
Yard & Food Biosolids Generator 13,500 tons garden & farm compost 5,600 tons commercial compost 21,000 tons Yard Trimmings & up to 22,000 tons Food & Compostables 16,000 tons Wastewater Biosolids Methane Green electricity for 1,400 homes Usable heat For wastewater processes Anaerobic Digestion Waste Transformation AD could reduce our greenhouse gases by 20,000 tons/year
The Potential for Anaerobic Digestion
60,000 Tons of Waste Processed
20,000 Tons of Greenhouse Gas Reductions
Eliminates sewage sludge incineration
Converts waste to renewable energy
Reduces landfill methane
Eliminates waste hauling
Savings & Revenue
$1.4 million/year in green energy
$800,000 energy from incineration
$234,000 from eliminating waste ash
$200,000 from compost sales
$1 million in tipping fees
Carbon dioxide offsets
Anaerobic Digestion Would Save Palo Alto Money Expense/Revenue Item Offsite AD Initial Capital Cost 0 $13.75 mil. Annualized Capital Cost 0 $19.64/ton Estimated Operating Cost $41/ton $38.22/ton Revenues - Product Sale 0 -$8.33/ton Revenues - Electricity Sales 0 -$21.04/ton Revenues - Other Sales (CO2) 0 -$1.55/ton Total Net Cost Per Ton $41 $26.94
Possible Funding Sources
The Site would be at the Landfill Next to the Wastewater Treatment Plant
The Facility Would Require Undedication of 10 Acres (8%) of the 126-Acre Byxbee Park
An Equal Amount of Parkland could be Dedicated Elsewhere in Palo Alto Former Los Altos Water Treatment Plant site
Savings from an AD Facility could Help Maintain our World-Class Parks Foothills Park
Or Complete 92% of Byxbee Park (no funds currently exist)
To Qualify the Initiative for the November Ballot we Must Collect 4,356 Valid Signatures
Pros of Initiative Cons
Keeps Palo Alto’s composting operation and distribution local.
Enables Palo Alto to compost food waste.
Allows Palo Alto to retire its sewage sludge incinerator.
Generates enough green energy to power 1,400 homes.
Energy will be available during emergency blackouts.
Reduces citywide greenhouse gas emissions by 20,000 tons per year.
Saves the City $1,000,000 per year.
Revenues could be used to complete 92% of Byxbee Park (no funds currently exist).
Provides an excellent educational opportunity for school groups and others.
Serves as a model for other communities, reinforcing Palo Alto’s status as an environmental leader.
