However, the two countries shared similar trends, as Sweden’s proportions slightly rose and doubled in 2010.
In contrast, Australia underwent a downward trend throughout the years. Starting of with 10% of renewable energy, this figure gradually dwindled and reached its bottom in 2010 with roughly 5%. Although Turkey came second in its proportion of this energy type, it saw fluctuations over the years and eventually reported to touched its lowest point at 32% in 2010.
