For a presentation

This is not for a special moment,
but I'm doing a presentation about renewable energy sources, and I want a song or good music that goes well with the presentation,
any ideas?
thanks

Just a few ideas:

Apples In Stereo - (The World Is Made Of) Energy
Ben Harper - Better Way
Louis Armstrong - What A Wonderful World
Corporate Avenger - Earth Song
Clint Mansell feat. Kronos Quartet - Summer Overture (Instrumental)
Rob Dougan - Clubbed To Death (Instrumental)
Nooshi the Balloon Dude - Solar Power Princess
Marvin Gaye - Mercy Mercy Me
