The bar chart depict the diffrence between of percantages sustainable energy of the general supply in 2000,2004 and 2007.
Overall, it can be seen that although four countries showed the increased disparities between porcantages of renewable energies, Where Norway and Iceland had significant growth in energy during the period. However Australia and Germany have lower total energy figures than the other two regions
The begin with, In 2000, the energy resources started at approximately 62% in Norway, Whreas this figure during the next seven year, increased by 26%. In Iceland energy the levels were relatively stable at around 52% and 58% in 2000 and 2007.
In Germany a considerable change can be seen in three years. The renewable energy supply rised to 12% in 2000 and then nearly 15% in 2004. In 2007, It almost decreased While the Australias sustainable energy to share a little change, in 9% . By the end of the period this figure estimated to 10% in 2007 but In 2004, it experienced 11 percent.
