A school in the capital of Easter Island (Rapa Nui, in the local indigenous tongue) gives an example of clean management with the use of solar energy, rainwater recovery and an organic vegetable garden, as well as rooms and spaces built with waste materials.
Solar panels shine on the rooftop terraces of 10 neat buildings with perfectly straight lines and of uniform height, an image of modernity that contrasts with the precariously-built dwellings with unplastered concrete block walls just a few metres away, with rooms added in a disorderly manner, surrounded by a tangle of electric cables.
Social organisations in the central Mexican municipality of Yecapixtla managed to halt the construction of a large thermoelectric plant in the town and are now designing a project to convert the installation into a solar panel factory, which would bring the area socioeconomic and environmental dividends.
“We can’t work just to pay the electric bill,” complained José Hilario dos Santos, president of the Residents Association of Morro de Santa Marta, a favela or shantytown embedded in Botafogo, a traditional middle-class neighborhood in Rio de Janeiro.
Black plastic pipes, readily available on the mainly empty shelves of Cuba’s shops, distribute biogas to homes in the rural town of La Macuca, buried under the ground or running through the grass and stones in people’s yards.
"Solar energy makes my happiness complete," said Divina Cardoso dos Santos, owner of one of 740 houses with photovoltaic panels on the rooftops in a settlement on the outskirts of this central Brazilian city.

"We can't work just to pay the electric bill," complained José Hilario dos Santos, president of the Residents Association of Morro de Santa Marta, a favela or shantytown embedded in Botafogo, a traditional middle-class neighborhood in Rio de Janeiro.

Young Peruvians plan to take advantage of the knowledge acquired in Brazil's semi-arid Northeast to bring water to segments of the population who suffer from shortages, after sharing experiences in that ecoregion on the multiple uses of renewable energies in communities affected by climatic phenomena.
In Africa, over 640 million people – almost double the population of United States – have no access to electricity, with many relying on dirty sources of energy sources for heating, cooking and lighting.
While not offering a solution to the electricity gap in Africa, Brian Kakembo Galabuzi, a Ugandan economics student, can offer a cleaner and cheaper solution.
