Data definition
Inclusions and exclusions
Primary Energy Consumption — - Primary Energy Consumption refers to the total amount of energy consumed by a country before conversion into secondary energy forms such as electricity, heat, or refined fuels. It represents the consumption of energy from primary sources including fossil fuels, nuclear energy, and renewable energy sources within a given year. The metric is generally measured in Exajoules (EJ) and provides an overview of a country’s overall energy demand, economic activity, industrial development, and energy system structure. Primary Energy Consumption is an important indicator for evaluating energy usage patterns, resource dependence, energy security, and long-term energy transition trends across countries.
The data includes consumption of primary energy from major energy sources such as coal, crude oil, natural gas, nuclear energy, hydroelectricity, wind, solar, geothermal, biomass, and other renewable energy sources. It covers energy used across different sectors, including industrial, residential, commercial, transportation, and power generation activities. The dataset accounts for energy input before transformation into secondary energy products, allowing measurement of total energy demand at the national level. It includes domestically consumed energy and follows standardized calculation methodologies based on energy statistics from national sources and international energy databases, enabling comparison of energy consumption trends among countries.
The data excludes secondary energy products after conversion, such as electricity and refined petroleum products, when measured separately from their original primary energy inputs. It does not represent only electricity consumption or final energy consumption by end users. The indicator does not directly measure energy efficiency, energy affordability, carbon emissions, or the quality and reliability of energy services. Energy losses occurring during energy transformation, distribution, and transmission are accounted for according to the methodology used but do not represent actual useful energy consumed by consumers. Minor differences may occur due to variations in national statistical reporting, estimation methods, and energy accounting practices.
About this indicator
Primary Energy Consumption — - Primary Energy Consumption refers to the total amount of energy consumed by a country before conversion into secondary energy forms such as electricity, heat, or refined fuels. It represents the consumption of energy from primary sources including fossil fuels, nuclear energy, and renewable energy sources within a given year. The metric is generally measured in Exajoules (EJ) and provides an overview of a country’s overall energy demand, economic activity, industrial development, and energy system structure. Primary Energy Consumption is an important indicator for evaluating energy usage patterns, resource dependence, energy security, and long-term energy transition trends across countries.
Measured in Exajoules (EJ), the dataset represents the total primary energy consumed across the country and serves as an important indicator of energy utilization, economic activity, and infrastructure development.
Taiwan recorded primary energy consumption of 4.80 EJ in 2015, followed by a slight increase to 4.82 EJ in 2016 and 4.83 EJ in 2017. Consumption continued to rise to 4.88 EJ in 2018 before declining to 4.79 EJ in 2019. In 2020, energy consumption decreased further to 4.65 EJ due to changes in economic activity and energy demand conditions. Consumption recovered in 2021, reaching 4.94 EJ, before declining to 4.75 EJ in 2022. In 2023, Taiwan recorded primary energy consumption of 4.53 EJ, representing the lowest level during the observed period.
Overall, the dataset demonstrates a relatively stable but slightly declining trend in Taiwan’s primary energy consumption between 2015 and 2023. The period experienced moderate growth before 2019, followed by fluctuations influenced by economic conditions and changing energy requirements. The decline after 2021 reflects adjustments in energy demand and consumption patterns.
The dataset is valuable for analyzing Taiwan’s energy consumption trends, evaluating long-term demand changes, and comparing national energy usage patterns with other economies. It supports research related to energy planning, sustainability strategies, infrastructure assessment, and policy development. Additionally, the data provides useful insights for researchers, analysts, and policymakers studying energy efficiency, consumption behavior, and the future transformation of Taiwan’s energy landscape.
