Chapter 8, Problem 1STP

To determine

To Choose: The correct option.

Answer to Problem 1STP

Option C

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 power came from fossil fuel is,

  $P=100\%-\left(P_{\text{Nuclear}}+P_{\text{Hydroelectric}}+P_{\text{other}}\right)$

Calculation:

Substitute all the given values in above expression.

  $\begin{array}{c}P=100\%-\left(P_{\text{Nuclear}}+P_{\text{Hydroelectric}}+P_{\text{other}}\right)\\ =100\%-\left(20\%+8\%+3\%\right)\\ =69\%\end{array}$

Conclusion:

Thus, the correct option is C.
