Introduction

● La Follette School of Public Affairs

● Special Thanks to Jeanne Hoffman ● International Council for Local Environmental Initiatives (ICLEI)

● Goals and Importance

Inputs Sectors for community emissions analysis● Madison energy

● Residential energy● Commercial energy● Industrial energy

● Transportation and mobile devices● On- and off- road transportation● Public transportation: public transit

● Waste● Solid and water waste generated by households and businesses

Data Collecting

● Data were gathered from state and local governmental departments, as well as private organizations.

● Energy: Madison Gas and Electric (MGE) & Alliant Energy

● Transportation: Madison Metro Transit, DNR and Regional Airport

● Waste: Dane County Public Works and Madison Metropolitan Sewerage District

● Demographic data: U.S. Census Bureau

Results

● 2012 4,438,398 metric tons of CO2e compared to 3,954,293 metric tons in 2010 ● 18.5 metric tons per person

WI average 16.7 metric tons in 2011

Madison Resident (18.5 metric tons)

U.S. (16.9 metric tons)

Wisconsin Resident (16.7 metric tons)

Top 3 Energy Sectors Remain the Same

● Commercial energy, transportation, and residential energy remain the top 3 emitters.

CO2e Reduction Strategies

● Commercial Energy – Benchmarking

● Transportation – Bus Rapid Transit

● Residential Energy – Solar Electricity Generation

Commercial Building Energy Benchmarking

Requirement that owners of buildings with more than a specified amount of square footage must publicly report information regarding building energy consumption.

● Energy Star Portfolio Manager● 35,000 Buildings tracked from 2008 - 2011● 2.4% Annual reduction ● 7% total reduction over study period

● Study of California IOUs Program● 0.13 kWhs/square foot ● 0.002 therms/square foot

Commercial Building Energy Benchmarking

At a threshold of 25,000 square feet● 5,859 metric tons of CO2e per year

● 1,233 passenger vehicles per year ● 535 residential homes per year

Residential: Solar Energy

● The City of Madison has been promoting solar technology at the local level since 2007

● MadiSUN program

Forecasting Logistics

● Target 1 Megawatt by 2020 (Start year 2015)

● Average cost for installation $5.00/W

● $620,000 annual spending required for constructions through 2020

● Focusing on solar energy in residential sector (Using 2012 Residential price for electricity $.1188/kWh)

● Expecting 200 kW installed capacity will be annually deployed through 2020
