This report explores the potential of wide bandgap (WBG) power semiconductor devices, such as SiC or GaN, in enhancing energy efficiency compared to traditional silicon-based systems. Estimating global energy savings, the research focuses on applications like data centers, photovoltaic inverters, low-voltage motor drives, electric vehicle charging stations, inverters for battery storage, and laptop chargers.

Findings indicate substantial annual energy savings exceeding 120 TWh, equivalent to twice Switzerland’s electric energy demand. The study acknowledges its conservative nature, not accounting for all WBG applications or potential future growth in sectors like photovoltaics. Despite uncertainties, the results underscore WBG power electronics’ significant role in achieving global energy efficiency.
