Renewable Energy Consumption in Five Countries (2010 vs 2025)
"The bar chart below shows the percentage of total energy generated from renewable sources in five European countries in 2010 and 2025 (projected). Summarise the information by selecting and reporting the main features, and make comparisons where relevant."
A grouped vertical bar chart illustrating the percentage of electricity derived from renewables (wind, solar, hydro) in Germany, Spain, Sweden, Italy, and the UK in 2010 alongside 2025 projected figures.
The bar chart compares the proportion of electricity generated from renewable resources across five European nations in 2010 with projected figures for 2025.
Overall, renewable energy consumption is expected to experience substantial growth in all five surveyed countries by 2025. Furthermore, Sweden maintained the highest share throughout the period, whereas the United Kingdom displayed the most rapid relative expansion.
In 2010, Sweden led the cohort with nearly half of its energy (48%) generated from renewable sources, followed by Spain at approximately 32%. Italy and Germany recorded moderate shares of 26% and 22% respectively, while the UK registered the lowest proportion at merely 12%.
By 2025, Sweden’s green energy output is projected to surge to 68%, cementing its dominant position. Similarly, Spain and Germany are forecast to witness marked increases, reaching 50% and 42% respectively. Meanwhile, renewable generation in the UK is anticipated to escalate nearly fourfold to 44%, surpassing Italy, which is expected to register the slowest growth, climbing modestly to 38%.
Examiner Rules for Grouped Bar Chart
- When future dates appear on charts, use projection verbs such as "is predicted to", "is projected to", or "is anticipated to" rather than simple will/would.
