Taking up the gauntlet brashly thrown down a few weeks ago by Taiwan
, the Spanish city of Seville has launched a diabolical scheme to replace its halogen and incandescent traffic lights with LEDs. The switch to the new system will be undertaken gradually and will cost the town nearly €2.3 million, but when complete will conserve 85% of the energy used previously. Seville plans to replace 22,170 lamps in total, which will reduce energy drain annually by 3.93 million KWh, or 800 residential homes. No word, however, on what the province plans to do about its "Barber" problem.
