Human Economic Welfare Index (HEWI) Composite index of human economic welfare Encompasses factors omitted by GDP Maintains utility of an easily measured index, e.g. CPI Components of HEWI Personal Disposable Income (PDI) Human Welfare Government Expenditure (HWGE) Full Employment Index (FEI) Economic Welfare Index (EWI) -- equality Combined Education Index (CEI) Health Adjusted Life Expectancy Index (HALE) Energy Efficiency Index (EEI) 3
Energy Intensity Source : Marina Fischer-Kowalski and Helga Weisz, “Transition to a Globally Sustainable Metabolism—Possible and Impossible Futures” Presented at the 2008 Conference of the International Society for Ecological Economics, Nairobi, Kenya, August 2008; p. 7. Energy Intensity is Energy consumption per unit of GDP 4 75%
Projected US Energy Intensity Source EAI = 1 5 15% Evolution of economy: Services now account for 78% of US GDP & 64% of global output
Fossil Fuel Energy Intensity for Selected OECD Countries 1970–2008 6 USA 60% UK 55% Switz 40%
Fossil Fuel Energy Efficiency Index (EEI) Relates fossil fuel energy consumption to Economic Welfare Household consumption expenditure + Government welfare related expenditure Health Education Social protection & employment insurance Housing Environmental protection Measures changes over sliding10 year periods Higher EEI reflects investments in sustainability Shift to renewable sources Improved energy efficiency Shift to less energy-intensive economic activities 7
EEI for Select Countries: Energy Intensity unit: Btu/ 2000 intl dollars PPP; FFEC in BTU per dollar.
