The line graph illustrates the use of recyclable energy in six different countries, showing the estimated share of total energy consumption between 1971 and 2011.
Overall, Finland, Denmark, and France recorded higher proportions of renewable energy, although their trends remained unstable. In contrast, Germany, the United States, and the United Kingdom showed steady increases throughout the period.
In 1971, France stood at approximately 8%, and Denmark at 15%, while Finland exceeded both by reaching exactly 25%. After five years, Denmark and Finland fell slightly to 13% and 22%, whereas France rose marginally to 12% by 1976. All three countries remained unstable until around 1991, after which they began to increase steadily. By 2011, France reached 14% and Denmark 18%, while Finland showed the highest figure among the three at 24%.
In contrast, Germany, the US, and the UK started at significantly lower levels compared to the other countries. The UK stood at just 1%, and the US at around 3% in 1971. Germany began at 5% but declined to 4% by 1986, while the US and UK rose gradually to 6% and 3% respectively by that time. The US experienced fluctuations until 1991, after which it rose sharply to 18% in 2011. Germany and the UK continued to increase gradually; the UK levelled out at 5% between 2001 and 2006 before finishing at 6% in 2011. Germany saw a sharper rise and peaked at 14% at the end of the pe
