Japan’s Ricoh Taps Wind, Solar Power to Fuel London Billboard

Ricoh Co., the Japanese office-equipment maker, said it erected the world’s first billboard fueled by wind and solar power.

The 12-by-3-meter (39-by-10-foot) sign is on the U.K.’s M4 motorway linking London to Heathrow Airport, said Tom Wagland, head of the environmental management group at Ricoh’s European unit. It’ll advertise Tokyo-based Ricoh’s products and follows the installation last year of a solar-powered board in New York’s Times Square, he said.
