Solar Cookers International (SCI) helps lead global efforts to promote solar cooking. Solar cookers have no emissions and use free solar energy accessible worldwide for cooking and water pasteurization. SCI raises solar cooking knowledge and awareness by organizing and attending international conferences. It also hosts the Solar Cookers International Association, the Solar Cooking Wiki, as well as SCI's organizational website. This work assists in the achievement of the United Nations Sustainable Development Goals.
Tens of thousands of individuals and organizations from around the world have learned about solar cooking through SCI's advocacy, leadership, education resources, and information exchange network. SCI, based in Sacramento, California, USA is a 501(c)(3) nonprofit, non-governmental organization supporting and reporting on the work of hundreds of partner organizations and individuals in 142 countries.
- SCI has consultative status with the United Nations Economic and Social Council (ECOSOC).
- SCI sponsors the Solar Cooking Wiki (this site), an internationally recognized resource for solar cooking information.
- SCI was named as a winner in the Keeling Curve Prize for sustainable planet solutions in August 2021. SCI won for its work “improving human and environmental health by supporting the expansion of effective carbon-free solar cooking in world regions of greatest need” in the Social and Cultural Pathways category.
- SCI has a 4-star rating from Charity Navigator.
- SCI's Worldwide Office is located in Sacramento, California, USA (Map).
In addition to its advocacy, leadership, research, and networking activities, SCI provides grant funding to pilot projects that focus on innovative processes that scale up solar cooking technologies in the regions of the world where the human and environmental needs are greatest.
Solar Cookers International is spearheading the solar cooker Performance Evaluation Process (PEP). Evaluation of the performance, user experience, and quality of solar cookers was identified as a high priority by the attendees of the 5th SCI World Conference in Sacramento, California, USA, 2014. The process and instrumentation was presented and demonstrated at the 6th SCI World Conference in Gujarat, India, January 2017.
If you would like to promote SCI's global work to introduce solar cooking technology to families around the world to improve health, quality of life, and the environment, please make a donation online or to the postal address below. The majority of SCI's funding comes from individual donors and foundations supporting social impact and environmental sustainability.

Most significant solar cooking projects
- A refugee camp in Kenya was the first to receive a large scale solar cooking project - The Kakuma Refugee Camp was formed in 1972 when Sudanese refugees first arrived in Kakuma, Kenya. Introducing solar cooking to the camp was Solar Cookers International’s first large-scale refugee project, beginning in January 1995. Kakuma had considerable refugee turnover, but by 2004, when Solar Cookers International (SCI) concluded the project, the camp had tripled in size to nearly 90,000 refugees. Though rapid growth posed problems for assisting all those who wanted to solar cook, SCI ultimately served over 15,000 families. This project was one of the earliest to use the CooKit solar panel cooker to introduce solar cooking. The program also extended solar cooker technology to schools, especially primary school, through demonstrations, poems, songs and drama.
- November 2021: Solar Cookers International presented advancements made in solar cooking at this year's COP26
- October 2021: Recognizing the need for solar cooking: - Solar Cookers International was pleased to be recognized for its effort in promoting solar cooking by CNN. Approximately four million solar cookers are in use at this time worldwide, helping to save entire forests from destruction. SCI Advisor, Janak McGilligan, describes the efforts the Jimmy McGilligan Centre for Sustainable Development has contributed to many communities in India with their solar cooking introductory programs.

- August 2021: SCI named as winner! - Solar Cookers International has been named as a winner in the Keeling Curve Prize for sustainable planet solutions. SCI won for its work “improving human and environmental health by supporting the expansion of effective carbon-free solar cooking in world regions of greatest need” in the Social and Cultural Pathways category. Dr. Shishpal Rawat, SCI’s Board President, said, “This recognition helps elevate the role of solar cookers as a key technology to reducing greenhouse gas emissions.” SCI estimates that there are over four million solar cookers directly and positively impacting over 14 million people, preventing over 5.8 million tons of CO2 emissions annually, equivalent to taking more than 1.25 million cars off the road, and an estimated 30 million tons of CO2 is prevented over the lifetime of solar cookers distributed, equivalent to not burning over 34 billion pounds of coal or driving over 76 billion miles.

- June 2021: Solar cookers and sustainable cooking equipment distributed in Nepal - With assistance from Solar Cookers International, approximately 300 people from especially vulnerable groups from communities in Kathmandu, Lalitpur, Bhaktapur, Kavre, Okhaldhunga, and Solukhumbu districts have received solar cookers, solar dryers, heat-retention boxes, and water pasteurization and safety equipment, as well as the necessary training. These locations in Nepal have limited local resources, and the new appliances help the recipients be better prepared for the challenges facing their communities.

- June 2019: Solar Cookers International opens new PEP testing center at the University of Nairobi, Kenya - SCI’s PEP test allows manufacturers and consumers to know the cooking power of solar cookers without brand bias and to develop a baseline for comparison. PEP testing demonstrates to solar cooker users and investors the power, in watts, they can expect from a specific model of solar cooker. SCI PEP results are trustworthy because the PEP test is based on an internationally accepted protocol for testing and reporting solar cooker performance. SCI also has centers in Lalitpur, Nepal; New York, USA; and California, USA. Having global locations for SCI PEP testing centers is important to advancing the adoption of solar cooking worldwide and affirms SCI’s role as the leader within the solar cooking sector. Local testing of solar cookers supports the regional economy, job growth and builds capacity in the sector.
