One megawatt (MW) of wind power produces enough electricity to supply approximately 275 homes. For a recent year, the state of Texas produced \(3352 \mathrm{MW}\) of wind power. (Source: American Wind Energy Association) a. About how many homes can be supplied with electricity using wind power produced in Texas? b. The given table outlines new proposed wind power projects in Texas. If these projects are completed, approximately how many additional homes could be supplied with electricity? $$\begin{array}{l|c} \text { Project } & \text { MW } \\ \hline \text { JD Wind IV } & 79.8 \\ \hline \text { Buffalo Gap, Phase II } & 232.5 \\ \hline \text { Lone Star I (3Q) } & 128 \\ \hline \text { Sand Bluff } & 90 \\ \hline \text { Roscoe } & 209 \\ \hline \text { Barton Chapel } & 120 \\ \hline \text { Stanton Wind Energy Center } & 120 \\ \hline \text { Whirlwind Energy Center } & 59.8 \\ \hline \text { Swcetwater V } & 80.5 \\ \hline \text { Champion } & 126.5 \\ \hline \end{array}$$
