Energy in Tanzania



While hydropower is currently the largest source of renewable electricity, solar and wind power are projected to provide significant generation capacity to support the country economic development. There are significant climate challenges, however, with developing additional renewable energy capacity:

  • Annual and inter-annual variability of the climate can lead to energy shortages, and limitation in generation capacity. The current energy mix has a significant dependency on reservoir fed hydropower. Droughts, such as those experienced in 2006 and 2011, both reduce the availability of water in reservoirs and increase the pressure on using available water for agriculture and sanitation.
  • Climate change may both increase the frequency of climate conditions that impact power generation, livelihoods, health and wellbeing. Average annual temperatures are expected to increase between 1 and 3°C by the 2050s, impacts to wind, solar radiation and rainfall extent, timing and amounts are far less certain and thus need to be investigated.
