We’ve already heard that Al Gore is hard at work on a sequel to his documentary An Inconvenient Truth, but might Leonardo DiCaprio also be planning a follow up to his 11th Hour?

Chalk this one up to rumor folks, but the Chicago Sun-Times is throwing it out there that the 33-year-old actor is working on a new environmental doc — with energy mogul T. Boone Pickens possibly set to finance it.

This would be an interesting pairing. Pickens has recently been in the news due to his “Pickens Plan” — which promotes “alternatives” to oil, including natural gas, wind, and solar. A major part of the plan is “replacing the 22% of its electricity that the United States gets from natural gas with wind energy, which would then allow that natural gas to provide 38% of the nation’s fuel for transportation and reduce its dependence on foreign oil.” He’s also currently deep in plans to build the world’s largest windfarm down in Texas.
