WT’s total energy consumption was 19,451 GJ in 2023. The biggest source of energy was non-renewable electricity purchased from power companies, accounting for 94.74% of the total consumption. The total electricity consumption was 18,429.11 GJ in 2023, up 18.88% relative to 2022, as a result of the inventory scope expansion to the entire Group. The others were gasoline and diesel consumed by company fleet, totaling 1,022 GJ in 2023. The total energy consumption increased by 16.34% compared with 2022, as the scope was expanded to the entire Group. However, the intensity measured by floor area decreased by 5.12% relative to 2022.

The Taiwan Ministry of Economic Affairs’ plans to achieve 20% renewables in electricity generation matrix by 2025 and the Paris Agreement pursues efforts to keep the temperature rise under control. In response, despite not being a major electricity consumer or carbon emitter subject to prioritized control, WT purchased 10,000 kWh of renewable energy certificates in 2023 to understand Taiwan’s renewable energy procurement process. The renewables make up 0.41% of the consumption in Taiwan, and a 100 KW solar system was installed in the Shanghai offices (completed in Q1 2024) to generate electricity mainly for self-use. WT will continue to conduct feasibility assessments on green power generation, green electricity purchase, and renewable energy certificates, in order to gradually increase the proportion of renewable energy usage.

WT’s total energy consumption was 16,271‭ ‬GJ in 2022‭, ‬with an increase due to the inclusion of operating bases in China and South‭ ‬Korea in the scope‭. ‬The biggest source of energy was non-renewable electricity purchased from power companies‭, ‬accounting for 95.27%‭ ‬of the total consumption‭, ‬and the others were gasoline and diesel used by company fleet‭. ‬As of the end of 2022‭, ‬the non-renewable energy utilization rate was 100%‭, ‬and no renewable energy has been used‭. ‬The Shanghai Office is planned to be equipped with solar power generation systems in 2023‭ ‬to increase the utilization rate of renewables‭.‬

 

The total electricity consumption was 4.3061‭ ‬MWh in 2022‭, ‬of which the total electricity consumption in the areas where the GHG‭ ‬emissions inventory was verified‭ (‬logistics centers in Taiwan‭, ‬Hong Kong and Singapore‭) ‬was 3.0889‭ ‬MWh‭. ‬The electricity consumption intensity was 76.88‭ ‬kWh/m²‭, ‬down 0.63%‭ ‬compared to 2021‭.‬

 

As fuel consumption is closely related to the operating activities‭, ‬the combined energy intensity of gasoline and diesel was therefore measured by revenue‭. ‬In 2022‭, ‬the energy intensity of gasoline and diesel was 0.0013‭ ‬GJ/million NTD-revenue‭, ‬significantly down 18.75%‭ ‬from 2021‭.‬

Note 2‭:‬In 2022‭, ‬the operating bases in China‭, ‬Hong Kong‭, ‬South Korea‭, ‬and Singapore were newly-included in the voluntary inventory scope‭. ‬Due to the nature of electricity consumption in which form the majority of the energy was consumed by WT‭, ‬the energy consumption intensity was measured by floor area‭, ‬and the coverage rate of the energy disclose scope was 99.06%‭ ‬in 2022‭.‬

Note 3‭:‬The electricity data were taken from the electricity bills of each bases‭, ‬and the gasoline and diesel data were taken from the record on the CPC Electronic Billing and Collection System‭ (‬EBCS‭) ‬and the fuel invoices‭.‬

Note 4‭:Thermal conversion factor for electricity‭: ‬1‭ ‬kWh purchased electricity‭ = ‬0.0036‭ ‬GJ‭;‬

Note 5‭:‬Thermal conversion factors for fuels were taken from the Annual Energy Report of the Bureau of Energy‭, ‬Ministry of Economic Affairs‭, ‬which were 1‭ ‬liter of motor gasoline‭ = ‬7,800‭ ‬kcal‭, ‬and 1‭ ‬liter of diesel oil‭ = ‬8,400‭ ‬kcal‭.‬

Note 6‭:‬1‭ ‬kcal‭ = ‬4,186‭ ‬joules

Note 7‭:‬The electricity intensity was measured by floor area‭, ‬see Note 7‭ ‬for GHG Emissions Intensity‭; ‬the gasoline and diesel combined intensity was measured by annual revenue‭, ‬see 2-2‭ ‬Stable Financial Performance for operating incomes of the years‭.‬

 

In 2021, WT’s total energy consumption is 8,168.08 GJ, of which the most important energy source is non-renewable electricity purchased from power companies, with electricity consumption accounting for 91.18% of the total consumption, while the rest is fuel used in ccompany work vehicles. In the future, depending on the overall energy policy and climate change issues, proper planning and setting will be made to target the use of renewable energy. Total electricity consumption in 2021 was 2.0688 million kWh, with an electricity consumption intensity (GJ/floor area) of 0.28 GJ/m2, a decrease of 8.72% compared to 2020, mainly due to a significant increase in the number of home-based office workers. Therefore, there was a reduction in office electricity consumption due to COVID-19 and the raising of the alert level to 3 in Taiwan beginning in May 2021. The energy intensity of gasoline and diesel fuel is closely related to the nature of the operating activities and is calculated based on the revenue. Gas and diesel energy intensity of 0.0016 GJ/million in 2021 – a significant decrease of 56.85% compared to 2020 due to reduced use of company vehicles as a result of reduced customer visits and the implementation of work from home measures for about three months because of COVID-19. Gasoline consumption was 22,064 liters in 2021, a 45.09% reduction compared to 2020; the vehicles which ran on diesel fuel were scrapped in 2020, so diesel consumption was 0 liters in 2021. 

1:The inventory boundary covers WT Microelectronics, Morrihan International Corp., Techmosa International Inc., Maxtek Technology Co., Hongtech Electronics Co., Nuvision Technology, Inc., Brillnics (Taiwan )lnc., WT Joint Staff Welfare Committee, and other operating bases in Taiwan, in which 12 offices are added in Zhonghe and Hsinchu in 2021.

2:The data source for electricity is Taipower’s billing data, and the data source for gasoline and diesel is the EBCS Goldstream operating platform of CNPC.

3:Power conversion factor: 1 kWh of purchased power = 0.0036 GJ

4:Calorific value conversion coefficients for each energy source: The source is the calorific value table of energy products in the annual report of the Bureau of Energy Statistics, Ministry of Economic Affairs. 1 liter of motor gasoline = 7,800 kcal, 1 liter of diesel = 8,400 kcal

5:1 kcal = 4,186 joules

6:The denominator used for electricity intensity is floor area, please refer to Note 7 for greenhouse gas emission intensity; the denominator used for gasoline and diesel intensity is annual revenue, please refer to 3-2 Financial Performance for historical operating revenue.
