Timilsina, GovindaSikharulidze, AnnaKarapoghosyan, EduardShatvoryan, Suren2016-07-062016-07-062016-06https://hdl.handle.net/10986/24619Armenia and Georgia are taking the climate change agenda seriously and contributing to efforts for mitigating global climate change through various ways, including preparation of low-carbon development strategies for their future economic growth. The improvement of energy efficiency is one of the key elements of the low-carbon development strategies. This study develops a methodology to estimate a marginal abatement cost curve for energy efficiency measures and applies it to the building sector in both countries. The study finds that among the various energy efficiency measures considered, the replacement of energy inefficient lightbulbs (incandescent lamps) with efficient lightbulbs is the most cost-effective measure in saving energy and reducing greenhouse gas emissions from the building sector. Most energy efficiency improvement options considered in the study would produce net economic benefits even if the value of reduced carbon is not taken into account.en-USCC BY 3.0 IGOTOTAL EMISSIONSSUBSTITUTIONECONOMIC GROWTHREDUCING ENERGY CONSUMPTIONCALCULATIONGREENHOUSE GAS EMISSIONSELECTRICITY TARIFFCARBONHEATING SYSTEMSMARGINAL COSTGENERATIONDISCOUNT RATECOST OF ELECTRICITYCLEAN ENERGYEMISSIONSSOLAR WATER HEATERSGAS PRICESSUPPLY CURVESELECTRIC HEATERSINCENTIVESEMISSION REDUCTIONGASPRICEEFFICIENCY IMPROVEMENTMONETARY VALUEMARGINAL ABATEMENTGAS CONSUMPTIONCALORIFIC VALUESAIRGREENHOUSE GASPRESENT VALUECO2NATURAL GAS PRICESEFFICIENCY IMPROVEMENTSSCENARIOSOILEMISSION FACTOREFFICIENT LIGHTINGECONOMIC BENEFITSFEASIBILITYSUSTAINABLE ENERGYPOWER SECTORCAPACITYGHGOPTIONSOIL PRODUCTSGLOBAL WARMINGWATERCLOUDSIMPROVING ENERGY EFFICIENCYFUEL SUBSTITUTIONCONVENTION ON CLIMATE CHANGEENERGY AUDITMARKETSCARBON ECONOMYPOLLUTIONTOTAL COSTSIMPORTSGEOTHERMAL ENERGYGAS EMISSIONSENERGY POLICYFUEL CONSUMPTIONFUELSUNEPEMISSIONS REDUCTIONABATEMENT COSTCLEAN TECHNOLOGIESCARBON EMISSIONSHEATING SYSTEMRESIDENTIAL BUILDINGSQUANTITY OF FUELEMISSIONS REDUCTIONSANNUAL EMISSIONENERGY SAVINGSENERGY CONSUMPTIONEMISSIONGREENHOUSECONSUMPTIONHEATTHERMAL EFFICIENCYPOLICIESCLIMATE CHANGEENERGY EFFICIENCY IMPROVEMENTSBALANCEVALUEELECTRIC HEATERPOWERENERGY EFFICIENCY MEASURESELECTRICITYGAS SUPPLYECONOMIC SECTORSCLIMATEABATEMENTELECTRICITY GENERATION MIXELECTRICITY GENERATIONANNUAL COSTEMISSION FACTORSCLIMATE CHANGE MITIGATIONCONDITIONERSENERGY STRATEGYMARGINAL ABATEMENT COSTVALUE OF ENERGYMARKETGREENHOUSE ABATEMENTABATEMENT COSTSPOLICYGLOBAL ENVIRONMENTAL FACILITYENERGY EFFICIENCYDISCOUNT RATESELECTRICITY PRICESENERGY DEMANDNATURAL GASENERGY BALANCEINVESTMENTRENEWABLE ENERGIESCOALTARIFFINCANDESCENT BULBSSUPPLYFUELAVAILABILITYFACILITIESLOW-CARBONFINANCIAL SUPPORTENERGY EFFICIENT TECHNOLOGIESHOUSEHOLD ENERGYGLOBAL ENVIRONMENT FACILITYCOOLING SYSTEMSSPACE HEATINGKEROSENENATURAL GAS CONSUMPTIONFRAMEWORK CONVENTION ON CLIMATE CHANGECAPITAL COSTSENERGY EFFICIENCY STANDARDSPRICESAPPROACHGAS DISTRIBUTIONBENEFITSENERGYWorking PaperWorld Bank10.1596/1813-9450-7703
