Washington, Aug 22 (ANI): Brad Pitt firmly believes that America's dependency on oil can be stopped if people harness the energy of sun, water and air.

The actor, who has been involved with the Global Green USA project that is attempting to rebuild New Orleans one green house at a time, insisted to NBC's Ann Curry that half of America's, and the world's energy problems would be solved if they went green.

"The idea that we pay utility bills is absolutely unnecessary...There's the sun. It's right there to be harnessed. You feel the breeze that's been created here. And we got water right out there. Any one of these can be harnessed...It's simple. It's smart," usmagazine.com quoted him, as telling the host.

"It's the way we have to be thinking. There's a lot of problems in the world right now because of our dependency on oil," he added.

The actor also insisted that New Orleans, left devastated by Hurricane Katrina, should definitely be rebuilt

"I know a lot of the people here. I care very much for the area. I met a 60 year old man who...said [to me], 'I did everything right. I got a job. I bought a home. I raised my kids in that home. They did the same. Now...we're all split apart and we've been wiped out...What do I do?' And he's right...that's unacceptable. So any debate on 'should we rebuild, should we not' -- I'll take you on," he said. (ANI)
