## 7 Conclusions  
The electricity consumption in Mozambique will increase by 5-7% per year until 2070 due to increased wealth, a larger population and higher investments in the manufacturing and mining industries. The main electricity generation source in Mozambique is hydropower. Climate change will affect the temperature and precipitation patterns of Mozambique substantially. There is a close correlation between climate change and hydropower generation. With higher temperatures, the evapotranspiration increases too and reduces water levels in reservoirs and reduces runoff in rivers. One example is the hydropower plant of Cahora Bassa, where the electricity output may be reduced by 20% until 2100. Economic implications associated with this climate change phenomenon is higher in Mozambique than in neighboring countries as a result of the future electricity demand to a largeextent is forecasted to be met by hydropower. The large hydropower potential in Mozambique should be considered when investing in new power plants in southern Africa. It is important the southern African countries continue collaboration and develop mutual organizations to utilize the hydropower potential of their watersheds.  
A regression analysis model based on ordinary least square fits was used to evaluate the linear trends that can be expected to occur. Temperature and precipitation data for the rainy season in Mozambique (October-March) was employed for the climate change analyses that were carried out. In using this model, there were found to be close correlations between climate change and the generation of hydropower energy: with temperature increasing and evapotranspiration increasing as well, the water level in reservoirs and in the rivers are reduced.  
Regarding the climate-change projections, there is evidence that precipitation will decrease, thereby reducing river flow, which will lead to a decrease in the hydropower energy production available. The vulnerability to climate change can be expected to increase poverty in Mozambique, due to energy of this kind being a major source of income for the local economies and for the government. In addition, projections regarding the growth of the population show that by the year 2050 the population in Mozambique can be expected to be about 66 million. It is thus important that the government take steps aimed at increasing the capacity so as be able to meet this challenge.
