Association pour le Développement de l'Energie Solaire (ADES) is a Swiss NGO that produces energy-efficient cookers in Madagascar and encourages the use of renewable energy. In this way firewood and charcoal consumption can be substantially reduced. The project started in Tuléar in the south of Madagascar in 2001. Local production by local people with local material is part of the ADES philosophy. We have managed to install more than 170 000 ovens up to now (Status March 2018).
The deforestation problem
For centuries the population of Madagascar has been cooking their food with charcoal, which requires vast amounts of firewood in its production. About 90% of the original forest in Madagascar has been destroyed. It is not any more a green island but becomes more and more a red one. Madagascar has, especially in the south and southwest regions of the country, close to ideal conditions for the use of solar energy. The solar cookers and efficient stoves are an important contribution towards halting the deforestation process. Besides environmental reasons, there are also economical and practical reasons to favour the solar cooker. Families spend less money on wood and charcoal and cooking with the solar cooker avoids cooking over smoke fires and the associated respiratory disease.
In order to convince people of this new cooking method, ADES offers cooking demonstrations and training courses for women, who then recommend the stoves to others. There are also workshops for school teachers on environmental issues and the use of solar cookers so that they can integrate them into their teaching and promotional programs. Thanks to CO2 certificates, solar cookers can be sold at a reduced price to the population.
ADES has the vision that within 20-40 years of 2018, a large part of the population in Madagascar will predominantly be using energy-efficient cookers to prepare their food. Every year an increasing number of stoves are planned to be distributed. From 2011 to 2017 ADES sold a total of 169,713 energy-efficient stoves in Madagascar (of which 13,470 solar cookers and 156,243 energy saving cookers).
ADES has nine centres in Madagascar where they build and/or sell solar cookers. The production is well organized, but the promotion is more difficult because it takes a lot of training to convince the population to change their cooking habits. ADES offers various programs such as 'women teach women' and environmental education in schools.
NEW: Regional centres
- NEW: June 2018: ADES Annual Report: 2017; Regula Ochsner updates the projects happening in Madagascar. Besides their solar cooking and improved combustion stove initiatives focused on limiting deforestation, they include a mangrove restoration program, an education initiative supporting students at all levels, and locally sourced recycled metals repurposed into useful products.
- November 2017: Regula Ochsner, of Association pour le Développement de l'Energie Solaire, reports their solar cooking activity in Madagascar has remained busy, but not at the levels of recent years. She explained that with the development of cheaper improved combustion stoves, solar cooker sales have dropped to approximately 500 units a year from 1,500 units previously. Their efforts have paid off however, with the creation of 460 jobs, of which 150 were within ADES itself. Below, cooks are busy preparing meals with solar cookers manufactured at ADES facilities.
- July 2016: ADES is chosen as one of 100 Projects for the Environment.
- December 2014: ADES has created a document detailing their work in Madagascar: ADES from 2001 to 2013
- March 2013: Continuing with their holistic community approach, ADES began a program last November to place Sun Ovens and fuel-efficient woodstoves into a new local school canteen they helped to build. Now, 245 school children receive a warm meal once a day.
- November 2012: ADES from 2001 to 2012 - ADES started its solar cooking program in Madagascar in 2001 with a small carpentry shop under a party tent, two motivated carpenters and an instructress. Today we operate six centres with manufacturing facilities, a new sales point in Antananarivo, the capital and a coordination centre in Tuléar. ADES actually employs 85 persons and additionally created about 50 jobs in external enterprises. On average a family of 20 people is living off the salary of one employee. ADES is a socially sustainable employer. All the children of our employees go to school at our expense and the families are covered by health insurance. For each solar cooker sold we have two trees planted in a reforestation project in Madagascar.

- June 2011 The team of the Association pour le Développement de l'Energie Solaire (ADES) in Madagascar gathered last Saturday in Baar to unpack a novel solar cooker at the anniversary celebration of ADES. The Electro Solar Cooker comes with built-in photo cells and batteries to also provide power for lights, radios, and cell phone recharging, besides being an efficient solar box cooker. "This will make a sensation," says Regula Ochsner, founder of ADES. Especially valuable, is that the know-how transfer has gone the other way around for once: Madagascar supplies to Europe. Regula was enthusiastic but also a bit scared before the expected rush to the newest generation of solar cookers: "Can we handle the logistics as well?" This is the first time the latest prototype solar cooker has been presented to the general public, and it has happened in Madagascar. The work of ADES and its founder, Regula Ochsner from Ottenbach have received numerous awards, including the Swiss Solar Prize (2007), the Doron Prize (2008) or the price of the Brandenberger Foundation. The 10-year anniversary provides an opportunity to look back. Renewable energies point to the future. The event is even more poignant this year, in light of the tragedy in Fukushima. The non-profit organization has been committed to ADES in Madagascar for the past ten years to preserve the unique flora and fauna and promote sustainable cooking methods. In 2001, under the scorching sun in Madagascar, and under a party tent, the first solar cooker assembled. Today ADES employs around a staff of sixty. Countries with the use of solar and energy-saving stoves have already saved around 30,000 hectares of dry forest from logging. ADES first introduced solar cookers in order to reduce the deforestation of the dry forests, but now, in conjunction with solar cookers use, energy-efficient stoves have helped reduce wood consumption by up to 65%.

- April 2010: Since 2001, ADES has been making and selling solar cookers in the southwestern part of Madagascar, providing much-needed cooking alternatives as well as employment for over 30 local carpenters and trainers. In 2003, ADES built its first permanent solar cooker construction workshop in Tulear. A second construction workshop was established in Ejeda in 2006, followed in 2008 by a workshop in Morondava. Each of these regional centers also has sales and demonstration offices. Future plans include development of a fourth regional center in Anosy or Antandroy, and the creation of two or three local branches within each region to reduce transportation distances and increase outreach capacity. According to ADES, southwestern Madagascar experiences about 330 sunny days per year and is a nearly ideal region for solar cooking. However, per capita income in Madagascar is only about $400 per year, making it difficult for families to afford solar cookers and spend their meager income on a technology they are not familiar with. Rising firewood and charcoal costs over the past few years are making solar cookers comparatively more affordable, but still out of reach for many. Subsidies have mostly come from donors in Switzerland and a handful of awards. The Madagascar government has provided some additional support, partnering with ADES to promote renewable energy in Tulear. Hand-crafted wooden solar box cookers, produced locally for upwards of $200 each, are sold at a subsidized price of just over $20. These cookers reach temperatures of up to 150°C, and are commonly used to cook rice, various root vegetables, meat, fish, bread, and cakes. Metal parabolic solar cookers are assembled locally for about $160 each, from aluminum and steel parts made by another local organization at an already subsidized price. The parabolic cookers are then sold at a subsidized price of about $50. These cookers reach even higher temperatures, but require stirring of food and more frequent adjustments to track the sun. They are particularly useful for frying, and can work in a complementary fashion with solar box cookers. Both cookers come with 7-year warranties. By the end of 2009, ADES had sold 4,640 solar cookers. It hopes to ramp up its outreach and sales capacity with funding from carbon credit offsets.
