Along with the wind and solar energy projects in American Samoa, for which ground was broken this week, landfill waste will also be turned into energy.
The American Samoa Power Authority said a $US31 million project at the landfill would use all the waste, except for cement and metal, to produce electricity.
The authority's acting executive director, Wallon Young, said only a small amount of electricity would be generated, but the real benefit would be protecting the environment.
Meanwhile, two new renewable energy projects worth nearly $US150m have been officially launched in American Samoa.
One is a solar photovoltaic farm to be built near the Veterans Memorial Stadium in Tafuna, and the other is a wind energy project in Aasu village.
The contractor for the solar project, which has a price tag of $US43m, is Canadian Solar/Recurrent Energy.
It will generate 20 megawatts of electricity.
The wind farm, being built by Green Global Solutions, is worth $US100m and will produce 42 megawatts.
