People living on the island of Apolima in Samoa are now getting electricity 24 hours a day from solar power.
Over past years the fewer than 200 people on the island have received electricity for only 4 to 5 hours a day because of the high cost of running the island's diesel power generator.
The Prime Minister, Tuila'epa Sa'ilele Malielegaoi, says it's a challenge now for the world to seek other ways to generate power as of one day oil could run out.
Meanwhile the government's power authority is looking at the possible use of wind mills to produce electricity for the whole country.
