Nick Cunningham of Oil Price.com has written a timely article summarizing the World Cup's gargantuan energy consumption and carbon footprint. The World Cup soccer competition underway in Brazil is held quadrennially, and is apparently the most watched sporting event of all. This year's games are to culminate in the July 17 finale in Rio de Janeiro. The games appear likely to set both a viewing record as well as a record for energy consumption and carbon emissions. An estimated 900 million watched the opening ceremonies of London's 2012 Olympics. But the World Cup governing body FIFA's research suggests 909.6 million viewers watched at least a minute of the 2010 World Cup, and Cunningham tells us there may be as many as 3 billion viewers for this event in 2014. Moreover, broadcasting's technical innovations are proceeding apace. Ultra-high definition broadcasts (expected to become standard in 2017) are being used for three of this year's matches, taking advantage of the event's eyeball-dense economics. The official match ball is the Adidas Brazuca, one of which has its own twitter account and micro-cameras studding its surface.
