As a country with few natural resources to rely on, Portugal has traditionally relied on others for its energy needs. But now that's changing. The Portuguese government has invested in renewable energies, setting up wind farms, wave machines and the world's biggest solar farm.

These days, Portugal produces a huge amount of renewable energy and the resulting industries are successfully stemming the country's brain drain, particularly amongst Portugal's youth.Video journalist David Brill travels to Portugal and speaks to the experts, who all say there's no reason why other countries can't follow in Portugal's footsteps.

About International Dateline 

SBS Dateline, which began in 1984, is Australia's longest-running international current affairs program. It has a well-earned reputation for authoritative and incisive reporting. Dateline has taken the traditional way of producing TV current affairs and turned it on its head. Reporters who used to travel with a cameraperson and sound recordist now travel alone and have the responsibility of both filming and reporting their stories. The reporters became video-journalists, gaining access to people and places that the conventional camera crews cannot.
