​TAREA realizes its objectives through underneath activities:

Advocacy/Lobby:​TAREA conducts advocacy and lobby to create enabling environment (policies, regulations, finance schemes) for the implementation of activities that facilitate scaling up access to the renewable energy technologies. In the year 2015, it managed convincing Government of Tanzania retaining VAT exemptions on solar products and DC lights. In the same year 2015, TAREA managed to conclude the advocacy to Tanzania Vocational Education and Training Authority (VETA) to have renewable energy curriculum in place. Next step is advocating creation of the scheme of certifying renewable energy installers who have been trained informally.

​Training:​TAREA conducts different renewable energy related trainings to the instructors, installers, retailers, regulators, officers of district councils , decision makers, project developers and end users. The biggest work that was done by TAREA was training more that 400 installers and 50 instructors through the Tanzania Government project of Sida/MEM Solar Photovoltaic. TAREA with support of Tanzania Commission for Science and Technology (COSTECH) has initiated training of biomass stoves producers in the regions of Lindi and Mtwara. TAREA organizes opportunities for members to undergo continued trainings at the international level. Members have already participated in the trainings of efficient energy use (Sweden), Sustainable Environmental Assessment (Sweden), Wind power planning and use (Sweden and India), Solar photovoltaic (India and Egypt) and Wind power small turbines (India).

​Awareness raising:​TAREA conducts activities of raising awareness of renewable energy technologies to the planners, decision makers, financiers and end users. The awareness raising is done through installation of the renewable energy systems that are used for the community energy access and demonstrations, village energy demonstrations, national renewable energy days, radio and television live talk programs, printed materials like newspaper articles, leaflets and magazine of SunENERGY. It also conducts workshops, site visits, and programs of renewable energy lectures to the pupils of primary and secondary schools, and students of colleges and universities.

​Enabling community access to the renewable energy:​TAREA implements programs that enable communities access renewable energy. Some of the programs already implemented were installation of solar photovoltaic system at Matekwe Secondary School in Lindi, Feasibility study of renewable energy at Lugala Lutheran Hospital in Malinyi, installation of street lights at Malinyi bus stand and market place. Currently, it implements activities of enabling households access lighting solar kits through VICOBAs in Dar es Salaam and Malinyi.

​Sector and end users protection:​Tanzania is prone to the problems of substandard and counterfeit products of renewable energy technologies. The technology that is most affected is solar photovoltaic. TAREA works together with Tanzania Bureau of Standards (TBS) in developing standards and testing procedures. It further works with TBS in conducting market surveillance. On the demand side, TAREA conducts the campaign to sensitize the end users on the presence of substandard solar products and how to save themselves from the problems. TAREA provides "call recommendation service" to individuals who want to procure solar photovoltaic product.

​Promotion of environmental and energy efficient technologies:​TAREA promotes the use of energy efficient equipment/appliances, and solar power backup systems in place of petrol/diesel generators.

Research:TAREA conducts various research in the market information, environment protection and use of the renewable energy technologies. TAREA has concluded the research on the use of solar photovoltaic lanterns for fishing in Mwanza and is now facilitating distribution.

​Information collection and sharing:​TAREA collects various renewable energy information and share with the renewable energy stakeholders.

Renewable energy stakeholders networking:​TAREA works to network various renewable energy stakeholders at the national and regional levels. It networks members to the international bodies.

​Consultancy services:​TAREA provides technical supports to the project developers. The service consist of planning, designs and technical specifications, developing proposals, tendering process and verification of conformity to the specifications. TAREA is involved in the evaluation of the projects assessing the impacts. Some of the projects that are being supported by TAREA are solar projects of Masasi District Council and USAID TUNAJALI Program.
