The line comes from the Futurama episode Crimes of the Hot, first aired in 2002 as part of season four. In the episode, about global warming on future Earth, Morbo delivers the line during a news report in response to a confused explanation of wind power. Clips and quote posts later spread the moment across forums, reaction threads and soundboards, detached from the episode plot. It endures because the delivery turns a simple factual correction into a meme for any confident nonsense.
