Impacts of Electrification on CO2 Emission Reduction Potentials in the G7 Countries

摘要: Electrification is increasingly being considered to be a competitive option for CO2 mitigation. Because international cooperation imperative an effective climate change policy, it important obtain technology perspectives countries with large emissions. This study attempted quantify the emission reduction potential of two types electric technologies: heat pump technologies (HPs) and vehicles (EVs). The potentials were analyzed by considering ideal situation where all appliances are substituted, was determined on basis carbon intensity electricity in 2006. results showed that HPs can potentially reduce approximately 52% emissions from residential space heating water G7 simply improving efficiency combustion-type would 28%. Moreover, EVs 48% passenger cars, fuel conventional 40%. these 10% total In case already generate low-carbon electricity, electrification contribute further decrease
