Visualizing Power Consumption with Smart Outlets
Fujitsu, in collaboration with Yokohama City, conducted an experiment to measure PC power consumption using "Smart Outlet," a smart power strip with a built-in power sensor. This initiative aimed to assess the effectiveness of power-saving settings on PCs used in Yokohama City Hall offices. The results indicated that applying power-saving settings to all of Yokohama City's office PCs could potentially reduce annual power consumption by an estimated 220,000 kilowatt-hours (kWh).

An Intelligent Power Strip for Electricity Management
The experiment utilized Fujitsu's "Smart Outlet (FX-5204PS)," released in April of this year. This device boasts the precision to visualize power consumption from 1W for each connected device, even measuring standby power. By installing the accompanying software, users can monitor electricity usage per device on their computers, enabling efficient elimination of wasted power.
The survey was conducted over 13 days, from June 9th to 22nd, involving 36 office PCs (5 desktop PCs and 31 laptop PCs).
Through power-saving settings, a reduction of an average of 13.0Wh per desktop PC (approximately 20% reduction) and 1.0Wh per laptop PC (approximately 5% reduction) was achieved.
Yokohama City is promoting the implementation of power-saving settings for office PCs within its premises. It is estimated that applying these settings to all office PCs could lead to an annual reduction of approximately 220,000 kWh (a 14% reduction), equivalent to the annual power consumption of about 62 average households (86 tons of CO2).
