Community and household choices in energy services has realized the possibility of increasing ownership and community-participation during delivery ofsustainable energy services to communities without modern energy in Tanzania. TaTEDO uses participatory approaches as a major entry point for community mobilization and introducing sustainable energy technologies and related services at community levels. This has been facilitated through different participatory tools i.e. meetings and workshops in selected villages. The public meetings are also used for community mobilization and these meetings are major factors for bringing together beneficiaries for the purpose of creating awareness and forming sustainable energy groups (SEGs). Several awareness creation methods such as organizing seminars at district level to discuss strategies for scaling up the use of sustainable modern energy technologies and services have been undertaken to sensitize target groups and beneficiaries.
