 Tuvalu participates in the Alliance of Small Island States (AOSIS), which is a coalition of small island and low-lying coastal countries that have concerns about their vulnerability to the adverse effects of global climate change.The Sopoaga Ministry led by Enele Sopoaga made a commitment under the Majuro Declaration, which was signed on 5 September 2013, to implement power generation of 100% renewable energy (between 2013 and 2020).This commitment is proposed to be implemented using Solar PV (95% of demand) and biodiesel (5% of demand).
