The bar chart compares four different countries – Australia, Germany, Norway, and Iceland – in terms of the proportion of renewable energy in the total energy supply in the years 2000, 2004, and 2007.
Overall, although the share of renewable energy supply in Norway and Germany experienced upward trends, Iceland and Australia followed a similar downward trend, albeit with various degrees of decline by the end of the period. Of particular note is Norway, which stands out as the country with the highest proportion of renewable energy in its total energy supply throughout the period.
In 2000, Norway utilized 60% renewable energy in its total energy provision, showing a steady increase to just below 70% by 2007. Similarly, Germany’s use of renewable power increased steadily, starting the period with approximately 12% and reaching roughly 18% by the conclusion of the period.
In contrast, the renewable energy usage in Iceland increased gradually, reaching 60% before dropping to nearly 53% by the close of the period. As for Australia, the renewable power supply stood at only 10% in 2000. After a slight increase, this figure fell back to 10% by 2007.
