The following graphical data represents the annual percentage increase in three different renewable energy sectors (solar, wind, and hydropower) over a period from 2010 to 2020. The x-axis represents the years, while the y-axis indicates the percentage increase in output. Solar energy experienced a steep increase in the early years, peaking at 60% in 2015, followed by a gradual decline to 40% by 2020. Wind energy showed a steady increase, starting at 20% in 2010 and reaching a consistent level of around 35% by 2020. Hydropower, on the other hand, fluctuated modestly, beginning at 15% in 2010 and only rising to 25% by 2020, with notable dips in 2013 and 2016.
Based on the graphical data, which of the following statements can be accurately inferred?
