RESUMO

The programs for reduction of poverty and for providing people with access to the basic conditions for a good life quality should include solutions that take into account technological advances and the benefits of productivity and energyc efficiency. The use of solar collectors to replace electricity in water heating has already been adopted in several countries of the world, between the First and Second World Wars and on the first and second oil crises. Today it appears as an alternative that causes less environmental harm and brings financial gains to low income populations through electric energy savings. The energyc efficiency attained with solar collectors designed for small water volumes for consumption in bathing and the families’ adaptation to this technology have been verified by means of a case study conducted at the Sapucaias district, in Contagem, MG. The savings through the reduction of the energy bill are witnessed by the acquisition of electric and electronic goods and also by the aspirations and desires denoting new perspectives about the future, like possessing a personal computer. An inquiry on the actions of the several agents involved in the diffusion of the use of solar collectors among classes of lowcost houses in Brazil reveals that the successive programs, plans and goals proposed for incorporation in strategic development policies for the country have not been executed. The absence of an energy planning specific to the significant parcel of Brazilian population (49.7million people, 27.6% of its population) earning up to 2 minimum wages shows that public policies should be directed to the promotion of strategies founded on long term planning of large social reach. For this, parcel the expenditure with electric energy for bathing represents approximately 14 to 23 percent of their monthly income. The actions promoting the use of efficient technologies for the benefit of great parcels of population should be inserted in the strategic planning for the nation’s development, in line with all its other structures: economic, energetic, environmental, educational.
