To determine

To Choose: The correct option.

Answer to Problem 2STP

Option A

Explanation of Solution

Given info:

Percentage of electric power generated from nuclear power, $P_{\text{Nuclear}}=20\%$

Percentage of electric power generated from natural gas, $P_{\text{Natural}}=14\%$

Percentage of electric power generated from hydroelectric, $P_{\text{Hydroelectric}}=8\%$

Percentage of electric power generated from petroleum, $P_{\text{Petroleum}}=4\%$

Percentage of electric power generated from other resources, $P_{\text{other}}=3\%$

Formula Used:

The expression to determine the percentage if electric energy came from renewable energy resources is,

  $p=P_{\text{Hydroelectric}}+P_{\text{other}}$

Calculation:

Substitute all the given values in above expression.

  $\begin{array}{c}p=P_{\text{Hydroelectric}}+P_{\text{other}}\\ =8\%+3\%\\ =11\%\end{array}$

Conclusion:

Thus, the correct option is A.
