The pie charts depict the shares of various power generation technologies in the total electricity generation of a country for the years 2007 and 2023. The renewable sources of electricity generation consist of Hydro, Solar and Wind. Assuming that the total electricity generated remains the same from 2007 to 2023, what is the percentage increase in the share of the renewable sources of electricity generation over this period?
Correct : d
From the pie charts:
Year 2007:
Hydro = 30%, Solar = 5%, Wind = 5%
Total Renewable in 2007 = 30 + 5 + 5 = 40%
Year 2023:
Hydro = 35%, Solar = 20%, Wind = 10%
Total Renewable in 2023 = 35 + 20 + 10 = 65%
Increase in renewable share = 65 − 40 = 25%
Percentage increase = (25 ÷ 40) × 100 = 62.5%
The percentage increase in the share of renewable sources = 62.5% (Option D)
