The International Solar Energy Society (ISES) is a global organization for promoting the development and utilisation of renewable energy. ISES is a UN-accredited NGO and David S. Renné is the current president.
ISES was formed in 1954 as a world-wide non-profit organisation dedicated to the advancement of the utilisation of solar energy. ISES is now active in over 105 countries world-wide. Its members include scientists and researchers, plus many others from industry, solar energy associations and other private and public organisations.
ISES aims to bring recent developments in solar energy, both in research and applications, to the attention of decision makers and the general public, in order to increase the understanding and use of this non-polluting resource in everyday life.ISES promotes research, development and the use of technologies which are directly or indirectly fuelled by the sun and which minimise the consequences of energy use. These technologies can provide sustainable solutions for the supply of energy in both industrialised and developing countries.In spite of a historic focus on direct solar energy, ISES today is involved in all renewable energy fields.
