According to its latest sustainability report, TSMC (TSM.N) says AI and
advanced-chip demand has driven global expansion and higher power consumption.
TSMC used 28.77 bln kWh in 2025, up 12.6% YoY, equivalent to roughly 10% of
Taiwan’s annual electricity demand. The company aims for renewables to supply
60% of global operations’ electricity by 2030 (20.1% in 2025), 100% by 2040 and
net-zero emissions by 2050.
