Introduction to Energy Balance Table Tomoki Ehara Terms (Definitions) Terms (Definitions) Contents Basics of energy data • Primary Energy General descriptions Energy embodied in natural resources (e.g. coal, crude oil, sunlight, Interpretation Interpretation uranium) that has not undergone any anthropogenic conversions or transformations (IPCC). Rules/Conventions • Secondary Energy Analysis Form of energy generated by conversion of primary energies, e.g. Data preparation electricity from gas, nuclear energy, coal, and gasoline from mineral oil, coke and coke oven gas from coal (European nuclear society). • Total primary energy supply (TPES) T l i l (TPES) Total primary energy supply (TPES) is made up of production + imports - exports - international marine bunkers stock changes (IEA) • Total final energy consumption (TFC) Total final consumption (TFC) is the sum of consumption by the different end-use sectors (IEA). AIM Training Workshop Ohyama Hall, NIES, Ibaraki, Japan, Oct 22-26, 2007

Introduction to Energy Balance Table Tomoki Ehara Terms (Definitions) Terms (Definitions) Contents Basics of energy data • Energy intensity General descriptions Ratio between the consumption of energy to a given quantity of Interpretation Interpretation output. Rules/Conventions • Carbon intensity Analysis The relative amount of carbon emitted per unit of energy or fuels The relative amount of carbon emitted per unit of energy or fuels consumed. • Energy Service Useful energy output of any final technical energy consumption Useful energy output of any final technical energy consumption system. Examples of energy services would include - mechanical work, transportation, force - pumping, venting and vacuum applications - thermal uses (specific heating and cooling) h l ( ifi h i d li ) - lighting / illumination / magnification AIM Training Workshop Ohyama Hall, NIES, Ibaraki, Japan, Oct 22-26, 2007

Introduction to Energy Balance Table Tomoki Ehara Contents What is Energy Balance Table? What is Energy Balance Table? Basics of energy data • Simple Table Format General descriptions p • Illustrate general energy flow (production • Illustrate general energy flow (production Interpretation Interpretation to end-use) of a region in question Rules/Conventions Analysis • Flow (in row), Product (in column) ( ), ( ) • Input (-), Output (+) • Available at; – IEA, Energy Balances and Statistics (170 countries) – APEC, APEC Energy Handbook etc. gy – National statistics (each country) AIM Training Workshop Ohyama Hall, NIES, Ibaraki, Japan, Oct 22-26, 2007

Introduction to Energy Balance Table Tomoki Ehara Contents Why is EBT so important? Why is EBT so important? Basics of energy data • Easy comparison (by country, by year) General descriptions p Interpretation Interpretation • Easy interpretation E i t t ti Rules/Conventions • “Double count” avoided Analysis • Same format data available S f t d t il bl (Internationally) • But…a little differences in “definitions” (Be careful!!) definitions (Be careful!!)
