The line graph gives data about usage of renewable energy in 6 different countries accounting the total sources between 1971 and 2011.
Overall,Finland remained the dominant sources for most of the period, showing steady growth until mid year before slightly increasing. While other countries experienced the upward trend throughout the period.
The proportion of renewable energy which accounted for the total sources in the Finland at 25% in 1971 and this was followed by dramatic decline to around 15% with wild fluctuations in 1986. However,Denmark and France were started at 15% and 7% of energy sources, respectively in the initial year.Both of line experienced slight declines to 10% and 7%, respectively in 1968. Before a noticeable drop to 14% in 1987, the proportion of energy in Finland increased sharply to 24% in 2011. Meanwhile, Denmark and France witnessed a slight growth with wild flactuations to 18% and 15%, respectively in conclusion of the period in 2011.
Focusing on other renewable energies Germany and US were stood at 5% and 3%, respectively. The lowest trend United Kingdom started at 2% with minimal increases to 3% in 1981, after which it improved further to 6% in 2011.Moving on the proportion of energy produced by US rose to 10% in 1991,after which improved further to under 20% in 2011. Also Germany showed a slightly increase to 14% during the period in 2011.
