6,100 GW/year — power consumption comparable to Luxemburg's — is not a lot. However, each advanced chip takes over 4,000 steps to make, and there are hundreds of tools in a fab. EUV equipment accounts for approximately 11% of the total electricity use in a fab, with other tools, HVAC, facility systems, and cooling equipment making up the rest. As a result, the power consumption of all fabs equipped with low-NA and high-NA EUV tools is estimated to increase to 54,000 GW/year.
To put the number into context, 54,000 gigawatts a year of power is around five times more than Meta's data centers consumed in 2023. It is also more than Singapore, Greece, or Romania consume annually and more than 19 times the power consumed by the Las Vegas Strip per year. However, while this is a substantial amount of power, it is only 0.21% of the global power consumption in 2021 (25,343,000 GW/year), a rather small share.
