The illustrated line graph depicts the consumption of renewable energy accounting the total energy for over 4 decades, starting from 1971 and ending with 2011.
Overall, each catergory saw a marginable rise until the period given, with the exception for Finland that fluctuated before slightly declining in the end. 4 Countries such as France, Germany, United States, and United Kingdom have one thing in common: they began with mere numbers but by 2011, their figures either doubled or tripled. Even though Finland underwent the opposite process, it still merged as dominant figure among the remaining ones.
Nations that began with bigger numbers-over than 5-are Finland, Denmark, and France. Finland began with under 25 and fluctuated wildly between 24-16, after which it showed about 23 numbers of usage in 2011. The second was under 15 in 1971, and it reached its peak of 15 after two decades, following its trajectory until showcasing nearly 18 numbers of application of renewable energy. The same situation is seen in France, where it was about 8, and by subsequently rising climbed up about 14.
Categories with opposite beginings are Germany, the US, and the UK. By starting at just over 5, it nearly tripled in 2011, at about 13. The United States had 3 levels of renewable energy consumption, which by 2011 depicted its sixfold: approximately 18. Lastly, the United Kingdom experienced aforementioned trends: showing only 2 usage rates from the total energy in 1971, it demonstrated threefold increase by 2011.
