A survey of employees' home and workplace energy use has
revealed that office equipment eats up energy at twice the
rate of home equipment.
The in-depth study was conducted by Sun
Microsystems on a selection of its own employees,
who were equipped with a kilowatt-hour monitor that measures
Participants averaged a power consumption of 64W per hour
at home, compared with 130W per hour at a Sun Microsystems'
The results suggest that cutting down commuting by 2.5 days
per week could reduce an employee's energy consumption by
the equivalent of 5,400Kwh a year.
Employees who cut out their daily journey to a Sun office
also reduced their carbon footprints. Commuting accounted
for more than 98 per cent of employee work-related carbon
"We found that the energy used by working in the office
was about twice as much as that used when working from home,
which was a significant difference" - said Kristi McGee,
senior director for Sun's Open Work services group. "But

Sun has long been a pioneer in promoting the benefits of
