Improved biomass institutional stoves

Improved biomass institutional stoves have been disseminated in several Eastern and Southern African countries. In most institutions in the region, especially schools, firewood is used for cooking in an inefficient manner such as three stone fires or using traditional stoves or models which are only marginally better than the three stone fire. Consequently, a significant amount of live trees are cut down at a rate that is faster than they ... more...

Renewable Energy Cooperatives

Cooperatives, most generally put, are associations of independent individuals pursuing a common goal. This goal can be economic in nature, but does not have to be. Its origins lie in workers' cooperatives, but today there exist also housing and consumer cooperatives, cooperative banks, retail cooperatives, and others. For renewable energy projects in communities of various sizes, the cooperative model offers some intuitively fitting advantages.
Cooperatives are based on seven principles ... more...

Solar Cooling

Unlike solar thermal heating systems, the highest need for cooling (during the hottest months of the year or the hottest hours of the day) coincides with the greatest availability of solar power. For the purposes of air conditioning in the hot months, solar thermal installations are of interest even in locations that do not get intense sunlight throughout the year.
While this field of renewable energy is growing slowly, several ... more...

Wind Energy

Wind energy is one of the cleanest, most environmentally friendly energy sources in the world. It is cheaper than solar energy and widely available. Once installed the maintenance expenses are relatively low and the availability of the system (the percentage of time that the wind turbine is ready to generate) amounts to more than 98%. Further advantages include:
- Easy and quick installation
- Generation of local employment (can be ... more...
