Abstract:
Human energy related activity has increased the carbon dioxide concentration in the atmosphere by 40 % since the preindustrial area. A leading contributor to this is the burning of fossil fuels in order to extract energy. Due to this, we are today facing many issues following climate change and global warming. The search for renewable energy sources is therefor of outmost importance. The biggest renewable energy source today is hydropower. It is big in newly industrialized countries such as China and Brazil, where in the latter it covers over 70% of the electricity supply. A relatively unexplo
