The multi-tier approach to measuring energy access proposed in the Sustainable Energy for All (SE4ALL) Global Tracking Framework of 2013 introduces a five-tier measurement methodology based on various energy attributes, such as quantity, quality, affordability, and duration of supply. The approach makes it possible to compute a weighted index of access to energy for a given geographical area. Separate notes focus on multi-tier measurement of energy access for households, productive enterprises, and community institutions. The type of data required for a multi-tiered assessment of energy access in a given area can be obtained through surveys of actual energy availability and use among a scientific sample of all users in a given category (households, enterprises, community institutions). Survey questionnaires elicit information about each energy attribute, and the results are fed into the multi-tier matrices. Data may also be collected from energy suppliers to indicate the tiers of access that specific projects may deliver to a targeted population. Capturing the multi-dimensionality of energy access is important, because rapid expansion of access to energy requires both accurate assessment and tracking of progress. Under the new multi-tier framework, data from energy surveys are compiled and analyzed to produce an energy access diagnostic for a given area. The diagnostic includes an in-depth disaggregated data analysis and an aggregate analysis comprising a series of indices of energy access. Defining and measuring energy access by considering attributes of energy supply yields a better understanding of how various interventions improve access.en-USCC BY 3.0 IGOACCESS TO ELECTRICITYACCESS TO ENERGYACCESS TO MODERN ENERGYAFFORDABLE ENERGYAGRICULTURAL RESIDUESAIRAPPROACHAVAILABILITYBASIC LIGHTINGBATTERIESBIOGASBOTTOM LINEBRIQUETTESCHARCOALCLIMATECLIMATE CHANGECOALCOOKINGELECTRICITYELECTRICITY CAPACITYENERGY ACCESSENERGY CONSUMPTIONENERGY ECONOMICSENERGY EFFICIENCYENERGY OUTLOOKENERGY POLICYENERGY SECTORENERGY SERVICESENERGY SOURCESENERGY SUPPLIERSENERGY SUPPLYENERGY SYSTEMENERGY USEETHANOLFUELFUEL SWITCHINGFUELSGASGAS DISTRIBUTIONGASEOUS FUELSGENERATIONGRIDGRID CONNECTIONSGRID ELECTRIFICATIONGRID SYSTEMSHOUSEHOLD ENERGYKEROSENELIGHTINGLIGNITELIQUID FUELSNATURAL GASPEAK CAPACITYPELLETSPOLLUTIONPOWERPOWER PLANTSPROPANEQUALITY OF ENERGYREFRIGERATIONSAFETYSOLAR HOME SYSTEMSOLAR HOME SYSTEMSSOLAR LANTERNSSOLID FUELSSPACE HEATINGSUSTAINABLE ENERGYTARIFF STRUCTURETRADITIONAL BIOMASSUTILITIESVENTILATIONVOLTAGEWIDENINGWORLD ENERGYWORLD ENERGY OUTLOOKBriefWorld Bank10.1596/18677
