We are passionate about the energy access challenge in the developing world! Energy is the engine of sustainable development yet too many households, institutions and businesses are hindered by the use of dirty and inefficient fuels.
We believe that monitoring and evaluation are essential in order for improved cookstove interventions to achieve their full potential. We offer this service and give project implementers, stove manufacturers and funders the means to understand their stoves actual usage rates and the real life impacts they achieve.
