A Spanish city has found an unusual place to generate renewable energy — solar panels in the cemetery. Santa Coloma de Gramanet has installed 462 solar panels over its multi-story mausoleums. The plan was met with some derision at first, but thanks to a successful marketing campaign, the solar cemetery has public support. It has been such a success that there are already plans to install more panels in an effort to triple the amount of power generated. The installation cost 720,000 euros (£608,000) but will keep about 62 tonnes of carbon dioxide out of the atmosphere every year, said Esteve Serret, a director of Conste-Live Energy, the company that runs the cemetery and also works in renewable energy. I'm sure a solar powered zombie movie is already in the works.
