Tuvalu intends being 100 percent powered by renewable energy by 2020 as its commitment under the Majuro Declaration.
The declaration was the key decision to emerge from the Pacific Islands Forum summit in Majuro earlier this month.
In it Pacific countries commit to reduce their greenhouse gas emissions and Tuvalu's prime minister, Enele Sopoaga, says they intend following Tokelau as a country using only solar energy in place of diesel fuel to provide electricity.
He says he wants lighting on each of the nine atolls to be provided by solar by Christmas.
"We really need to be practical and we are going for partners who are working with us - New Zealand in particular, the European Union and Japan. And these things are doable and will save us a lot of money by moving away from petroleum to solar energy."
