Abstract
During the last decades, alerts raised warning from a more and more severe climate change. In this field, country's energy policy is a main question for tackling climate change. In fact, the man is commonly condemned by the climate change intensification. This can be closely linked to his overuse of fossil fuels. Those are the biggest issuers of greenhouse gases, particularly dioxide of carbon. Hence, for reducing carbon emissions the alternative is for renewable energy. This paper aims to highlight the environmental value of renewable energy in matter of carbon emissions dejection. In that regard, the neural approach was applied to approve the weak carbon intensity of renewable energy. Our results amply support the literary thoughts about renewable energy effectiveness and its low carbon emissions. So, renewable sources are on track for climate change mitigation.
