In alignment with the Ministry of Economic Affairs’ goal of achieving 20% self-generated renewable energy by 2025 and the Paris Agreement’s target of limiting global warming, WT Taiwan began transitioning conventional (grey) electricity with green electricity in 2024. Over the course of the year, the Taiwan operations procured 155,189 kWh of green electricity (including 152 Renewable Energy Certificates), resulting in renewable energy consumption of 558.68 GJ, accounting for 6.46% of total electricity use in the Taiwan region.
Additionally, a 100 kW rooftop solar system was installed at the Shanghai office and began operation in 2024. The electricity generated is primarily used for on-site consumption, totaling 104,613 kWh during the year. This translates to 376.61 GJ of renewable energy, covering 6.38% of the total electricity consumption in the China region.
In total, the Group’s renewable energy consumption in 2024 reached 935.29 GJ, representing 1.38% of the Group’s total energy consumption. To further encourage a transition away from fossil fuel vehicles, the Taiwan office introduced monthly electricity subsidies for employee-owned electric vehicles in 2024, effectively reducing GHG emissions.
Moving forward, WT will continue assessing the feasibility of solar generation, green power procurement, and renewable energy certificate purchases to progressively increase the share of renewables in its energy mix, supporting the goal of achieving net-zero emissions by 2050.
WT’s energy management efforts are centered on digitalized data monitoring and comprehensive equipment management to ensure optimal energy use efficiency. Through ongoing analysis of energy consumption patterns and load characteristics, the company conducts regular maintenance, upgrades, and replacements of existing infrastructure to reduce energy usage.
In 2024, WT’s primary energy source remained non-renewable electricity purchased from local utilities. Other forms of energy consumed include gasoline and diesel for internal operations.
Due to a significant increase in overseas operational sites following the integration of Future Electronics, the Group’s total energy consumption reached 67,641.91 GJ in 2024, an increase of 48,226.38 GJ compared to 2023. Notably, the newly added Future Electronics sites accounted for 48,679.14 GJ, approximately 72% of the total increase. This represents a year-on-year increase of 248.39%.

Annual energy consumption of the Group (Unit: GJ)
67,641.91 WT remains committed to continuously lowering its energy consumption and increasing the proportion of renewable energy used.With an annual electricity reduction target of 2%, we strives to enhance energy efficiency and uphold its social responsibility in promoting green energy and environmental protection.
Annual energy consumption of the Group
Note 1: Please refer to section “5-5 Greenhouse Gas Inventory and Verification Status” for organizational boundaries.
Note 2: Electricity data are sourced from utility bills of each operational site. Gasoline and diesel data are sourced from CPC Corporation’s EBCS financial operations platform or purchase receipts.
Note 3: Electricity conversion factor: 1 kWh of purchased electricity = 0.0036 GJ.
Note 4: Energy conversion coefficients for various fuels are based on the Energy Products Calorific Value Table from the Energy Statistics Annual Report by the Ministry of Economic Affairs’ Energy Administration: 1 liter of gasoline = 7,800 kcal / 1 liter of diesel = 8,400 kcal
Note 5: 1 kcal = 4,186 joules.
Note 6: The denominator for calculating energy intensity is floor area. Please refer to Note 6 of the Greenhouse Gas Emissions Intensity section.
Note 7: The coverage rate of data is calculated using the total floor area of the Group’s operational sites as the denominator and the floor area of the inventoried sites as the numerator.
