In an effort to spur small island nations to slash their dependence on fossil fuels, Caribbean politicians and renewable power experts are discussing clean energy on British billionaire Richard Branson's private isle.

The CEO of the Virgin Group of companies is hosting a three-day meeting of political and business leaders at Necker Island, Branson's home in the British Virgin Islands. It started Tuesday.

The event is organized by the Carbon War Room, a nonprofit firm Branson co-founded to promote cutbacks in greenhouse-gas emissions through private enterprise. It hopes to help islands become carbon-neutral.

Branson tells The Associated Press that the Caribbean can set a global example by embracing renewable power and energy self-reliance. The region now derives nearly all of its electricity from plants that burn imported oil and diesel.
