The given line graph illustrates the making use of of renewable energy accounting the total energy in six different countries between 1971 and 2011.
Overall, it is clearly noticeable that in five countries the use of energy increased substantially, except Finland with a small decrease. In addition, while the use of energy in the United States began at the small figures, it rose mostly compared to other countries.
Starting with the lowest figures, the United Kingdom started at about 1%, compared to the United States which accounted for about 3%. After 20 years, the use of energy increased significantly (9% and 3%). After 1991, the using of energy decreased to about 6%, before a sharp grow to approximately 18% in 2011, whereas the United Kingdom rose straight to 6%.
In 1971 Germany began at 5%, whereas France accounted for 7%. In 1976, the use of energy in France increased to about 11%, while Germany remained stable. In 1986 both Germany and France underwent a decline (4% and 7%). Finally, in 2011 Germany rose significantly to about 13%, whereas France increased to about 14% respectively.
From 1971 to 1976 the use of energy in Finland declined to about 20%, compared to Denmark which represented 13%. After fluctuating, in 1986the use of energy in Finland dropped to about 17%, whereas Denmark dropped to 10%. However, in 2011 both Finland and Denmark made an essential rise to 23% and 16%.
