Band 9: The graph below shows the percentage of total energy generated from renewable sources in four different countries between 2000 and 2020. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph compares the share of total energy generated from three renewable sources, hydro, wind, and solar, between 2000 and 2020.

Overall, all three renewable sources increased over the period. Hydro began as the largest source and grew steadily, while wind and solar started near zero and rose much more sharply, with all three converging at similar levels by 2020.

Hydro accounted for the largest share throughout, beginning at around 22% in 2000 and rising gradually to 25% in 2005, 30% in 2010, and 32% in 2015. By 2020 it stood at approximately 35%, although by this point its lead had been almost entirely closed by the other two sources.

Wind and solar began the period near zero. Wind sat at about 2% in 2000 and climbed slowly to 5% in 2005 and 10% in 2010, before rising more quickly to 20% in 2015 and 32% in 2020. Solar started lowest at 0% but increased the most sharply over the second half of the period, reaching 35% in 2020 to draw level with hydro.
