Problem 22

The table represents the world's major consumers of primary energy for a recent year. All measurements are in quadrillions of Btu. Note: 1 quadrillion = 1,000,000,000,000,000. (Source: Energy Information Administration, U.S. Department of Energy) Construct a bar graph using horizontal bars. The length of each bar gives the amount of energy consumed for that country. $$\begin{array}{l|c} \hline \text { Country } & \begin{array}{c} \text { Amount of Energy Consumed } \\ \text { (Quadrillions of Btu) } \end{array} \\ \hline \text { Germany } & 14 \\ \hline \text { Japan } & 22 \\ \hline \text { Russia } & 28 \\ \hline \text { China } & 37 \\ \hline \text { United States } & 99 \\ \hline \end{array}$$ (Bar graph can't copy)
