Sources of Energy Uses in the United States A break- down of the sources of energy used in the United States is shown below. Choose one energy source at random. Find the probability that it is a. Not oil b. Natural gas or oil c. Nuclear $$ \begin{array}{lll}{\text { Oil } 39 \%} & {\text { Natural gas } 24 \%} & {\text { Coal } 23 \%} \\ {\text { Nuclear } 8 \%} & {\text { Hydropower } 3 \%} & {\text { Other } 3 \%}\end{array} $$
Out of every 100 tons of coal fed into an electric generating plant, roughly how many tons produce the electricity you can use at your home and how many go into waste energy? Use the approximate energy flows indicated in Figure 21 .
