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.
