Seven-Eleven Japan Co recently announced it will replace in-store and signboard lights with energy efficient LED light bulbs at 5,000 outlets of its convenience store chain. This move is part of a 10 billion yen program aimed at dealing with the power shortages expected in Japan's eastern and northeastern regions this summer.
The goal of the program is to cut electricity consumption by 25 percent from July to September, and includes installation of solar panels on 1,000 Seven-Eleven stores. The Japanese government is considering limiting the use of electricity by major companies to deal with power shortages anticipated this summer as Tokyo Electric Power Co and Tohoku Electric Power Co struggle with lost supply capacity following the March 11 epic earthquake and tsunami.
Seven-Eleven of Japan has around 6,000 outlets in Tokyo Electric Power's service area, and will likely be targeted for electricity limiting. Installing LED light bulbs will free up a large portion of electricity, allowing Seven-Eleven stores to continue operating the same while using less energy.
Another company in Japan, FamilyMart Co, aims to reduce its electricity with a reduction in light bulb usage, and changing temperatures to adapt to changing seasons. In any case these are positive changes toward a more energy efficient future. It's unfortunate these sweeping changes had to be prompted by such dire circumstances.
