soccer stadiums help fight climate change in brazil
brazil is a solar energy pioneer in latin america. the country’s biggest photovoltaic facility is a unique one: it generates 600 mwh, but unlike other solar plants, it’s located on top of the estádio de pituaçu, a football stadium in salvador de bahia. the facility produces more electricity than the stadium actually consumes, and it is a model for the rest of the country — especially with brazil preparing to host the next world cup in 2014. there are plans to install solar roofs on further stadiums.
