The provided line graph illustrates the consumption of renewable energy accounting the total energy in six different countries namely Finland, Denmark, France, Germany, the US and the UK in a forty-year period, commencing from 1971.
Overall, there are pronounced variations in renewable energy usage among the surveyed countries. Also of note is that Finland and the UK consistently had the highest and lowest figures throughout the years.
To elaborate, in 1971, around 25% of the total energy used in Finland was renewable energy and this number slightly decreased to just under 24% 40 years later; despite this, Finland still ranked the first at the end of the period.The figures for Denmark and France ; however, witnessed a positive trend, rising from 15% and 8% to 15% and 17% respectively during the same period of time.
Regarding the other categories of the chart, the percentage of renewable energy consumed in Germany recorded a gradual growth from 5% to roughly 13% by 2011. The figures for the US also increased, with some oscillations in the first 25 years before remarkably growing from well under 5% to south of 20% in 2011 .Finally, starting at nearly 0% in the overall use of energy, the consumption of renewable energy in UK negligibly went up to 6% in the last year given, representing the bottoming position of the entire graph.
