The bar chart gives information about the share of renewable energy of the total supply in four different countries in 2000, 2004 and 2007.
Overall, Norway and Iceland were much more reliant on renewable energy than Australia and Germany, with shares of the former countries’ amounting to about three times the percentage those of the latter countries. It is also clear that percentage of all countries increased with the exception of Australia, whose proportion stayed more or less unchanged.
The holders of the biggest share of renewable energy- the Norway and Iceland did not witness a significant growth. For example, the latter’s proportion only grew by just under 5 percentage points as it almost felt back to its 2000 percentage of about 52 percent after experiencing a climb by about 8 percentage points. Similarly, having witnessed a negligible climb of 1 percent by 2004, Norway’s percentage continued going up, eventually reaching just below 80 percent.
The other two countries-Germany and Australia- utilized much less renewable energy. To illustrate, share of renewable energy was barely responsible for one tenth the total supply in Australia in 2000. Germany’s share of renewable energy hovered at around 10 percent in the remaining 2 years as well. The Germany, on the other hand increased dramatically from around 12 percent to just below 20 percent despite starting at the around the same percentage.
