It connects the fragmented dots of renewable energy advocates to build a global alliance, proving that being powered by 100% sustainable renewable energy is urgent and achievable. Hereby this unique campaign builds on initiatives that already take place on national, regional and local level and steers the global discourse on renewable energy towards 100% RE as the new normal. The goal is to initiate dialogue about 100% RE, build capacity and educate policymakers about the opportunities, case studies and stories that are happening all over the world. For this purpose the campaign aims to establish a global network of 100% RE regions.

ISES is a founding partner of the Global 100% RE Campaign.

Global Atlas for Renewable Energy

The Global Atlas for Renewable Energy is an initiative coordinated by IRENA, aimed at closing the gap between nations having access to the necessary datasets, expertise and financial support to evaluate their national renewable energy potential, and those countries lacking such elements. ISES is a technical partner of the GLobal Atlas for Renewable Energy. See an interview with Dr. David Renné, ISES president:

As of January, 2015, 67 countries and more than 50 institutes and partners were contributing to the initiative.

The Global Atlas facilitates a first screening of areas of opportunity where further assessments can be of particular relevance. It enables the user to overlay information listed in a catalog of more than 1,000 datasets, and to identify areas of interest for further prospection. IRENA is continuously adding information to the system.

Currently, the initiative includes maps on solar, wind, geothermal and bioenergy resources along with one marine energy map. The initiative will eventually encompass all renewable energy resources, providing global coverage through the first-ever Global Atlas for Renewable Energy.

Global Solar Council

The International Solar Energy Society (ISES) is a founding member of the Global Solar Council, launched at the COP 21 climate change meeting in Paris.

The worlds leading regional and national solar associations have come together to accelerate the uptake of solar technology across the globe.

The Global Solar Council strives to convey 3 Key Messages about solar power:

  • Solar power is already one of the cheapest forms of electricity globally
  • Solar power is everywhere, and alleviates poverty, especially in rural areas
  • To avoid a greater than 2ºC increase in global temperatures, we must strongly accelerate the deployment of solar power.

In 2015, solar accounted for about 1% of global power generation. Together we are targeting 10% global solar power by 2030.

At the launch of the Global Solar Council, ISES president Dr. David Renné stated: "The International Solar Energy Society has been strongly supporting R&D and technical innovation in the development of solar energy for over 60 years.  As a member of the Board of the Global Solar Council, we are very pleased for this opportunity to work with solar industry associations from around the world to continue our support in the advancement of these technologies, and to ensure their commercial success and mainstream application."

The principal members of the Global Solar Council include Australia, China, Europe, India and other Asian countries, Middle East, South America and the US.

Go 100% Renewable Energy

A global alliance of civil society organizations, academics, business associations and policy makers has called upon national legislators to commit to 100 percent renewable energy in the power, heating & cooling and transportation sector. At the Pathways To 100% Renewable Energy Conference, held in San Francisco, California on 17 April 2013, the alliance launched a new international campaign that seeks to build political will among a critical mass of decision makers and set a required goal of 100% renewable energies. Go 100% is a project of the Renewables 100% Policy Institute. ISES is a supporting partner.

Upgrading renewable energies mainly results in structural change from which regions and communities are the principal beneficiaries. Several regions, communities and cities for example in Germany and Denmark prove that this ambitious goal is already becoming a reality. The success story of those regions comes as a consequence of high citizen participation and the regional value creation taking place through decentralized energy production.

The alliance therefore calls upon local, regional and national policy makers to implement political frameworks that enable citizens and municipalities to profit from this transition.

To that end, knowledge transfer and exchange between policy makers are vital.

IEA Photovoltaic Power Systems Programme

The IEA Photovoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Agreements established within the IEA and, since its establishment in 1993, the PVPS participants have been conducting a variety of joint projects in the application of photovoltaic conversion of solar energy into electricity.
