Alternative Sources of Energy: Indigenous Renewable Resources

Abstract. This paper sees in indigenous biomass and other natural resources such as sun and wind and water, especially in Third World countries (most of which lie in the torrid or semi-torrid zones and a vast majority of whose populations live in rural areas), a potential alternative to non-renewable sources of energy such as oil and …
