Every coal$-$fired power plant outputs energy to the electrical grid at a certain rate and has a certain efficiency $.$ Consider three three coal$-$fired plants with the following values of those parameters: Plant $1$: P out $=0\mathrm{.}425$ GW$,$ e$=31\%$ Plant $2$: P out $595$ MW$,$ e $=36\%$ Plant $3$: P out$=525,000$ KW$,$ e$=34\%$ Consider the waste heat each of these power plants produces over the course of running for a full day. Rank the plants from smallest to largest $($left to right in the answer choices$)$ according to the value of this waste heat.
