Abstract
The electrification of cooking methods in Korea was investigated to understand the impact of different cooking methods on energy use and greenhouse gas (GHG) emissions in the building sector. Annual household cooking energy consumption was compared for the Nowon Energy Zero House Project, a zero-energy housing complex using induction cooktops, and a sample of households that used natural gas for cooking. The results showed that the former consumed less calories (a difference of 2.2 times) and emitted less GHGs (a difference of 2.6 times) compared to gas cooking households. A countrywide scenario analysis was conducted by combining the share of electric cooking households with the projected power generation mix in 2030. Under the 2030 Policy scenario for power generation, and with an electricity cooking share of 20%, cooking-related GHG emissions were projected to be 3.79 million t CO2/year; 3.8% (150,000 t CO2/year) lower than those in the present day, despite a total population increase. The electrification of cooking methods in Korea has the potential to reduce both the energy demand of the building sector and GHG emissions, in synergy with the decarbonization of the power generation sector.
Highlights
To meet the targets of the Paris Agreement, it is necessary to reduce dependence on fossil fuels and improve energy efficiency [1]
Korea aims to reduce 32.7% of CO2 compared to the business as usual (BAU) scenario in the building sector; it has introduced a building energy efficiency rating system, zero-energy buildings (ZEBs) certification system, and ZEB mandate roadmap [4]
The objective of this study is to analyze the impact of the electrification of cooking methods on the energy and greenhouse gas (GHG) emissions in Korea’s building sector
Summary
To meet the targets of the Paris Agreement, it is necessary to reduce dependence on fossil fuels and improve energy efficiency [1]. Substantial energy loss from space heating and cooling occurs in the building sector, leading to increased energy consumption and CO2 emissions [2]. The building sector accounts for over 40% of primary energy consumption and 28% of energy-related CO2 emissions [3]. In Korea, the building sector accounts for 20% of energy consumption and 25% of GHG emissions [4]. Several countries are implementing energy reduction policies in the building sector; including the improvement of energy efficiency by strengthening building energy standards and energy labeling for appliances, mandating zero-energy buildings (ZEBs), and expanding the supply of renewable energy [5]. In particular, has set targets to increase the use of renewable energy and electrification in buildings, with a focus on heating and cooling [6]. Korea aims to reduce 32.7% of CO2 compared to the business as usual (BAU) scenario in the building sector; it has introduced a building energy efficiency rating system, ZEB certification system, and ZEB mandate roadmap [4]
