Abstract:
Worldwide energy sector is essential for living and very important for development. For energy need, the world depends on different source of energy, among of them fossil fuels have played a big role, however, it has high contribution on Carbon dioxide (CO2) emissions. Nowadays the population growth and industries are rapidly increasing consequently, there is high energy demand, which increase the amount of fossil fuels to be consumed. The studied cases of two different thermal power plant has indicated that there is a huge amount of 561.935 Kg of CO2 per a day emitted due to full day operation. Nevertheless, the nations are moving in the direction of non-traditional energy assets, among which the sun powered fuel source is without contamination and limitless choice. Accordingly photovoltaic-diesel power age framework is one of generally encouraging of its great presentation, because of its low CO2 discharge considering to the independent diesel power age frameworks. The point of this research is to appraise the measure of carbon dioxide (CO2) emanations that can be diminished once a photovoltaic framework is corporate customary electrical organization. The present thesis measures carbon impression discharged for diesel generator as far as carbon dioxide before being integrated with PV system by considering the quantity of fuels used during energy generation and also on the amount of energy demanded by the loads. Also it estimates the amount of CO2 after being photovoltaic/diesel hybrid system. The research shows that there is a significate reduction of fuel consumed by diesel generator and with diesel working together with a solar photovoltaic, this fuel reduction resulting with a big amount of in CO2 of 401,243 Kg per a day, due to high solar radiation in Rwanda which can reach to 6KWh/m2/day, the research conclude that PV/diesel hybrid system is affordable in Rwanda and can be used as well of mitigating pollution, especial carbon dioxide emissions.
