1 Greenhouse Gas Emissions and Energy Efficiency Paula Hemmer Yin Pong Chang Division of Air Quality June 15,

2 Purpose of Presentation Greenhouse Gas Basics Co-benefits of energy efficiency reducing GHG saving money Opportunity for low cost energy assessment GHG Reporting 2

3 What are Greenhouse Gases (GHGs)? Gas in the atmosphere that absorbs and emits radiation in the thermal infrared range Linked to: Greenhouse Effect Climate Change Source: US EPA 3

4 “CO 2 Equivalent” CO 2 e = ∑ emissions i × GWP i GasFormula Global Warming Potential (100 years) Carbon dioxideCO 2 1 MethaneCH 4 21 Nitrous OxideN2ON2O310 Fluorinated gasesHFC, PFC, SF ,900 4

5  Vertical red bar at the end is the increase in atmospheric CO 2 levels over the past two centuries  Shows CO 2 levels have increased 100 ppm from pre-industrial levels  CO 2 level of 450 ppm is targeted as the critical threshold beyond which catastrophic and irreversible change might occur. Source US EPA Current concentration = 393 ppm (NOAA) 5

6 Primary Source of GHG is the Burning of Fossil Fuels Source Sector 2010 US Emissions in CO 2 e (million metric tons) Percentage of US CO 2 e Emissions 2005 NC Emissions in CO 2 e (million metric tons) Total Emissions5, Fossil Fuel Combustion5, % Power Plants2, %69.29 Industrial1, %14.99 Transportation %50.11 Commercial349.66%4.53 Residential228.64%7.29 6

8 Energy Assessment Co-Benefits Energy Assessment Gain Process Information Reduce Energy Use Reduce Emissions Less Regulation? More Sustainable Save Money More Capital Increased Profits Save Money 8

9 DAQ Grant for Energy Assessments  EPA/DAQ grant to provide cost-free or reduced-cost assessments  Goal is to educate facilities on interdependency between energy consumption greenhouse gas emissions energy costs  Program is open to industrial, commercial and institutional facilities  Applications need to be submitted by July 2013  More information and application: mechanical and aerospace ENGINEERING 9

10 Who is Getting the Energy Assessments? No. of applications = 35 No. of assessments completed = 19 No. of assessments “in the works” = 16 No. Available = Approximately 60 Types of facilities: Furniture Electronics Lumber Tobacco Chemical Hospital Food Paper Textiles Plastic Foam/Pipe 10

11 * The payback time for implementation of each energy conservation measures varies from 2 to 62 months, with an average time of 22 months. Some measures have immediate payback. 11 Potential Reductions Identified through Grant Facility Annual Energy Savings Annual Cost Savings ($/yr) Annual GHG Emissions Reductions (CO2e lbs/yr) Electricity kWh Nat.
