Advanced electric technologies include heat-pump water heaters and EVs. A combination of low-carbon power generation (such as renewables, thermal power with CCS, and nuclear) and advanced electric end-use technologies are a promising solution for drastic GHG (greenhouse gas) reduction. 2ObjectivesTo develop an IAM (integrated assessment model) based on a general equilibrium technique (Ramseys optimal growth theory) and including advanced end-use technologies such as heat pump water-heater and electric vehicles.Using the model, to analyze the effects of the advanced end use technologies. </p> <p>We conduct on-off analyses of the advanced end-use technologies and evaluate the importance of the advanced end use technologies.3BET modelBasic-Energy-Economy-Environment-and-Enduse Technology Model (BET).A MERGE-RICE type global model hard-linked with enduse technologies like MARKAL-MACRO.The economic module is an one-sector CES (constant elasticity substitution) type production function. The energy module is a bottom-up type model that describes vintage of energy facilities and electric load curves.The primary energy includes coal, oil, natural gas, biomass, nuclear, hydro, wind, photovoltaic, and backstop.World 13 regions; Simulation period: 2010 to 2230 with 10 year-intervals; an NLP model.</p> <p>45FigureThe modelstructure</p> <p>6</p> <p>TableEnergyServicesIn the modelRegions and Energy systems7BET 13 regionsRegion nameRegion 3 letterUSAusaUSAEurope (EU27+3)europeEURJapanjapanJPNCanada, Australia, and New ZealandcanzCAZOther EurasiaoeurasiaOEARussiarussiaRUSChina incl.

Such losses become larger with a more stringent climate policy. The advanced end-use technologies are a way to contain GDP loss when the climate target is stringent. (2) Electricity demand is relatively stable, but non-electricity demand decreases as the GHG constraints become more stringent. This is because electricity can be supplied using various low-carbon options such as renewables, nuclear , and thermal power with CCS.(3) Electrification rates based on energy services are high under stringent GHG constraints. The combination of electrification and advanced electric end-use technologies is a powerful method to achieve strict GHG constraints. </p> <p>14</p>
