SOLAR ALLIANCE
The International Solar Alliance (ISA) is an alliance of more than 122 countries initiated by India, most of them being sunshine countries, which lie either completely or partly between the Tropic of Cancer and the Tropic of Capricorn. now extended to all members of UN. The primary objective of the alliance is to work for efficient exploitation of solar energy to reduce dependence on fossil fuels. This initiative was first proposed by Indian Prime Minister Narendra Modi in a speech in November 2015 at Wembley Stadium, in which he referred to sunshine countries as Suryaputra ("Sons of the Sun"). The alliance is a treaty-based inter-governmental organization. Countries that do not fall within the Tropics can join the alliance and enjoy all benefits as other members, with the exception of voting rights.
Intiative was launched by Prime Minister Narendra Modi at the India Africa Summit, and a meeting of member countries ahead of the 2015 United Nations Climate Change Conference in Paris in November 2015.
Headquarters
It is headquartered in India. In January 2016, 
Narendra Modi, and the then French President François Hollande jointly laid the foundation stone of the ISA Headquarters and inaugurated the interim Secretariat at the National Institute of Solar Energy (NISE) in Gwal Pahari, Gurugram, India. The Indian government has dedicated five acres of land on the NISE campus for its future headquarters; it also has contributed 1.75 billion (US$24 million) to the fund to build a campus and for meeting expenditures for the first five years.
OBJECTIVE:-
The focus is on solar power utilization. The launching of such an alliance in Paris also sends a strong signal to the global communities about the sincerity of the developing nations towards their concern about climate change and to switch to a low-carbon growth path. India has pledged a target of installing 100GW by 2022 and reduction in emission intensity by 33–35% by 2030 to let solar energy reach to the most unconnected villages and communities and also towards creating a clean planet. India's pledge to the Paris summit offered to bring 40% of its electricity generation capacity (not actual production) from non-fossil sources (renewable, large hydro, and nuclear) by 2030. it is based on world co operation.
Future Target:-
India, with the support of France, has invited nations to facilitate infrastructure for implementation of solar projects. The alliance has been committed $1 tn as investment, and it is committed to making the costs of solar power more affordable for remote and inaccessible communities. The alliance will endorse India in achieving its goal of generating 100GW of solar energy and 175GW of renewable energy by 2022. The countries shall support each other in research and development as well as other high level activities.
Progress:-
On June 30, 2016, the alliance entered into an understanding with the World Bank for accelerating mobilization of finance for solar energy. The Bank will have a major role in mobilizing more than US $1000 billion in investments that will be needed by 2030, to meet ISA’s goals for the massive deployment of affordable solar energy. Till date 48 countries have signed and 26 countries have ratified the Framework Agreement of the ISA. With ratifications by 15 countries, the ISA will become a treaty based inter-governmental international organisation and it will be recognized by UN legally to become fully functionable.At the World Future Energy Summit (WFES) held in Abu Dhabi in January 2018, the government of India announced the establishment of a $350 million solar development fund to enable financing of solar projects.
