Show Hint
To calculate percentage increases, always compare the absolute increase to the original value. Use this approach for analyzing changes in shares or percentages.

The Correct Option is D
Solution and Explanation
Step 1: Calculate the total share of renewable sources in 2007.
In 2007, the shares of renewable sources (Hydro, Solar, and Wind) are: \[ \text{Hydro: } 30\%, \quad \text{Solar: } 5\%, \quad \text{Wind: } 5\%. \] The total share of renewable sources in 2007 is: \[ 30\% + 5\% + 5\% = 40\%. \] Step 2: Calculate the total share of renewable sources in 2023.
In 2023, the shares of renewable sources (Hydro, Solar, and Wind) are: \[ \text{Hydro: } 35\%, \quad \text{Solar: } 20\%, \quad \text{Wind: } 10\%. \] The total share of renewable sources in 2023 is: \[ 35\% + 20\% + 10\% = 65\%. \] Step 3: Calculate the percentage increase in the share of renewable sources.
The increase in share is: \[ 65\% - 40\% = 25\%. \] The percentage increase relative to 2007 is: \[ \frac{25\%}{40\%} \times 100 = 62.5\%. \] Final Answer: \[ \boxed{\text{(4) } 62.5\%} \]
