The power saving effects of telework were paid attention to soon after the East Japan Great Earthquake but they are scarcely reported in newspapers recently. Although the power saving in the office with telework is expected in air-conditioning, lightening and electronic appliances, energy use at home may be increased at the same time. In this study, 11 literatures which estimate the energy effects of telework are examined and compared. As for the literatures, the average increase of energy at home is 6.0kWh while the average decrease of energy in the office is 6.4kWh. The difference is not significant statistically and the power saving effects of telework are not clear. It is important to consider the condition of teleworking at home and the effects of the reduction of commuting in order to grasp the energy-saving effects of telework totally.
