This paper aims to analyze the photovoltaic electricity energy expansion and recent data about the behavior of the CO2 emissions in Brazil and other selected countries. Data were collected from different bases as International Energy Agency (Agência Internacional de Energia), Ministry of Energy and Mines (Ministério de Minas e Energia), Research Electric Company as well as other papers in the field. Kaya Identity was applied as basis in order to evaluate the CO2 emissions. As a result, it could be seen a clear domain of Germany and Italy in the photovoltaic generation sector, with high investments in the development and dissemination of that technology. Brazil presented an energetic matrix of low carbon but with a tendency to increase emissions per capita throughout the years. The effect of decoupling between the greenhouse gas emissions and the large-scale economic development was checked. It was realized that that phenomenon tends to intensify it since renewable energy technologies get higher levels of use.
The objetive of this work is to analyze the variation of CO2 emissions and GDP per capita throughout the years and identify the possible interaction between them. For this purpose, data from the International Energy Agency was collected on two countries, Brazil and the one with the highest GDP worldwide, the United States. Thus, the results showed that CO2 emissions have been following the country’s economic growth for many years. However, these two indicators have started to decouple in the US in 2007 while in Brazil the same happened in 2011. Furthermore, projections for CO2 emissions are made until 2040, considering 6 probable scenarios. These projections showed that even if the oil price decreases, the emissions will not be significantly affected as long as the economic growth does not decelerate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
