A recent study by Fujitsu Siemens claims that about $217 million (123 million pounds) is wasted every year in the U.K. alone powering PCs that could have been shut down or left in hibernation mode. The report also pointed out the environmental impact of all the wasted energy.
Though the study involved generic PCs, its results are also valid for Point Of Sale systems. Many shops leave the POS terminal running during the night, in order to start working directly when opening the shop the next morning, not realizing that they could save an significant amount of money on the energy bill.
