This year's Tokyo Game Show is aiming for a 25 percent reduction in energy consumption, in anticipation of a power shortage expected in the area this summer. The power shortage is expected due to a lack of resources following the damage done by March 11th's quake. While operations remain more or less normal at present, a rise in air conditioning expected soon will require rolling outages, according to Tokyo Electric Power. Tokyo Game Show said in a statement Thursday that it will replace existing expo center lights with power-saving LED bulbs. Additionally, it will not operate downward-moving escalators, and will limit the amount of power used by exhibitors. Tokyo Game Show, Japan's largest video game exhibition, will take place September 15 through 18 at the Makuhari Messe convention hall just outside Tokyo. According to show organizer CESA, 146 companies will exhibit to 190,000 attendees this year.
