A new apartment complex in San Isidro, or a high tech Five Star Hotel in Santa Cruz, Patagonia would seem like good places to see some of Argentina’s newest developments in alternative energy. However for one organisation, the successful implementation of alternative solar energy strategies has been helping small communities in some of the most remote parts of the country and world for over the last two decades.
Swimming towards a different horizon, EcoAndina director Silvia Rojo, her father and a few other technicians were the little fish aiming to make use of the big sea of energy when they decided to spend days upon the high Argentina Andean plateau closer to the sun as an unknown organisation investigating a new sustainable form of energy for the looming energy crisis times ahead. An ambitious and visionary initiative at the time, EcoAndina seemed to see what lay on the other side of the barren, dry, and llama-filled steeps, when they put into action the implementation of solar technology, portable water, and social development for the “Puna” region of Argentina’s Jujuy province.
At over 3,000 metres in altitude the environment of the Puna provides some of the most solar radiation in the world. In fact, it ranks together with places like Tibet, and Australia. This aspect combined with the fact that the extremely dry region experiences over 300 days a year of cloud-free sunshine makes solar energy a beneficial way to provide solar kitchens, water heaters, heated bathrooms, and even entire solar towns in order to better the conditions for people living in some of the most remote areas of the province. Natural materials and a majority of nationally-made products are used today to fabricate equipment for anyone including small community members near the salt flats to environmental friendly hotels being constructed in the touristy Quebrada de la Humahuaca.
Today the sun acts as EcoAndina’s number one business partner, but when the organisation began 20 years ago it was the lack water that brought the group’s founders together with an idea for change. In 1989, current EcoAndina president Silvia Rojo’s father – a geologist from Jujuy – convinced a German friend Barbara Hoizer, a biology professor and her husband Einrich Kleine-Hering, a hydrologic geologist, to come from Germany to visit the unique geologic landscape of Argentina, and to see firsthand some of the living conditions of many Jujeños in the Puna.
“My father invited them because he thought it was a good idea that they see how some of these communities got their water from rivers and didn’t have any stable drinking water,” explains Rojo. But once Einrich and Barbara arrived, they fell in love with the Puna, and decided to stay and form a group of working technicians with a goal of offering drinking water in 1991.

Rojo explains that the two most important factors for the Puna are the water and the energy, and the German couple soon realised after spending time on the high mountain plateau that the region wasn’t employing what they saw as the abundant sustainable energy outlet. With the help of the German Embassy and funding from a German organisation Amigos Alemanes de la Puna (German Friends of the Puna) Einrich was able to bring back solar box ovens and water heaters to see how they would work.
The atmosphere and in particular the high level of thermal energy in the Puna originally caused doubt, yet once the first couple of installations proved successful, EcoAndina began to set out on the road towards improving solar energy use in the area. The numbers show that the organisation’s goal has been steady with installations of over 320 solar family kitchens, 70 solar systems for hot water, 25 solar box ovens, 15 solar community kitchens, and nine heaters to add to a continued list of different solar equipment.
Rojo says that all of this progress is due largely to their ability to take advantage of the 200 kilowatts per hour that the Puna receives. “Here there is constant solar radiation during the whole year which makes it very easy to provide solar energy for everything,” says Rojo. “An equation that shows the clear advantage that we have here is one barrel of petroleum of 190 litres equals the solar energy produced in a metre squared per year. It is as if it were a sea of energy!”
EcoAndina has been able to complete most of its solar equipment installations in almost 30 distinct towns in the western province due to a base camp they established called EcoHuasi (ecological house) in the remote town of Misa Rumi. Rojo comments that most of the 30 towns are places which nobody visits because the highways don’t extend out towards this section of the province. “Nobody goes to this area,” says Rojo, “because most of the mountain roads fall apart with the rain. We’ve personally had six vehicles breakdown in the last 20 years.”
One reason for the high rate of lost vehicles is because of the increased amount of trips technicians from EcoAndina have been making in the last five years. Rojo is humble to point out that while EcoAndina may be seen as a progressive alternative energy movement, it is also still a very small organisation with a small infrastructure that doesn’t have a large budget for technicians. Despite EcoAndina’s low profile, Argentina’s – and the world’s – new focus on developing sustainable energies solutions has made presentations for projects based on alternative energy easier to come by. As of the year 2006, life got much busier Rojo says as eight of the ten projects presented in letters of convocation were approved by different national and international science and development foundations.
The approval of continued projects has been good news for the organisation as they have been able to go beyond their original installation of solar kitchens and water heaters to include bigger projects. In 2008, EcoAndina completed their biggest installation project with the development of the first ‘Pueblo Solar’ (Solar town). The project decided to focus on one of the highest and most remote locations in the western province. The town Lagunillas del Farallón, at around 4,200 metres above sea level, was chosen primarily because it is a town with constant growth of around 300 plus people, and good education with both primary and secondary schools.
Instead of implementing individual solar equipment installations, the organisation decided to go ahead with a whole thermal solar system in order to provide the community with a solar kitchen with a bread oven in the school, solar bathrooms, a heater and a solar water heater so that the whole town could bathe. “There wasn’t a shower until we installed a bathroom and the people would bathe from fountains by throwing water on themselves. The thermal temperature is very wide ranging at high altitudes. You can have 20 centigrade at mid-day and -20 centigrade at night. The water and air is very cold and people do not only get sick from bathing themselves, but they also get sick from the cold environmental climate.”
The solar towns have become an important goal for the organisation as a result of the lack of combustible found in this region. The problem of desertification has taken its toll as the constant extraction of regional bushes like the yareta and tola for use as a combustible has worsened the local ecosystem. “There’s each day less firewood because the people have no other option,” says Rojo. “Propane gas in the Puna is $20 more than that in San Salvador de Jujuy. This is because the trucks carrying propane gas can’t easily arrive on the local roads. Instead people have to pay for transportation to carry them down to buy it.”
EcoAndina has so far seen some great improvements in combating the desertification as a result of their installations. They say solar kitchens have been proven to lower the consumption of firewood by around 50-70%. This is significant news considering a typical family consumes around five tonnes of tola firewood to cover their basic energy needs per year. While the environmental benefits regarding towns in the Puna are sure to be seen, Rojo also sees the creation of solar towns as a way to encourage people to not feel like they have to leave their homes and head to big urban centres.
“I see with lots of enthusiasm a lot of Andean solar towns, and I’m sure that we are going to have members who continue our idea and are able to give the people a lot more services in order to continue working in these remote places. In the Puna they have their sheep, their llamas, their arts and their crops to cultivate. If someone improves the places where these people live, these people will not have to centralise in the same cities.”
The future of the EcoAndina as an organisation seems to have become solidified after 20 years. Providing solar energy for the remote communities in the Puna continues to be the group’s objective, they now have a workshop for their own fabrication of equipment and are in the process of constructing a model house with solar instruments which will act as a the central offices for the organisation. The path towards establishing their solar technologies has been a 20-year long journey, and with more than half of the constructing on the house waiting for approved funds, and a beat up old truck, Rojo admits that there is never a slow moment in the search for new funding. Funding or not, Rojo understands the need for patience, but also has kept her sights forward towards the possibility of offering thermal solar plants for the generation of electricity of cities in the future.
