AIDG is a non-profit that implements sustainable building systems in the developing world, with a specific focus on Guatemala and now Haiti. They do several interesting things with water including hydroelectric and solar hot water.
What I find interesting about this work is that most NGOs dealing with water focus on providing water for consumption, while maybe not dealing with the energy related issues. While I cannot comment with great authority on the merits of
small-scale hydro electric systems, I can speak a little about the benefits of
solar hot water generation.
In case you don't realize it, generating hot water is a major energy hog in a household where it is available. Heating water directly from the sun is relatively easy and FAR MORE EFFICIENT that using wither electricity of fossil fuels. On top of that, the systems are fairly cheap and easy to maintain. Consider them for yourself and consider
DONATING to AIDG.
