Studies on the effects of information provision on residential energy use conclude that such information can promote households' energy-saving investments and conservation behavior. However, most of these studies are conducted in the U.S. or in other OECD countries, where households, on average, are richer and consume more electricity. This study evaluates the effect of descriptive information provision on residential electricity consumption in a less wealthy OECD country – Lithuania. By using a randomized experiment, we find that the availability of descriptive hourly electricity information provided on web portals reduces electricity consumption by about 8.6%. This effect is equivalent to an annual energy saving of 241 kWh per household. The effect is more pronounced for households with high energy consumption, living in rural areas and detached houses.

对信息提供对住宅能源使用影响的研究得出的结论是，此类信息可以促进家庭的节能投资和节约行为。然而，这些研究大多是在美国或其他经合组织国家进行的，平均而言，这些国家的家庭更富裕，消耗的电力更多。本研究评估了描述性信息提供对不太富裕的 OECD 国家——立陶宛居民用电量的影响。通过使用随机实验，我们发现门户网站上提供的描述性每小时电力信息的可用性减少了约 8.6% 的电力消耗。这种效果相当于每户每年节能 241 千瓦时。对于高能耗家庭，效果更为明显，
