Like Stevens Point’s Fire Station No. 2 (above), all of Madison’s fire stations generate solar hot water, as described in “Solar hot water douses rising energy costs at Madison’s fire stations,” published by Focus on Energy:

. . .each of Madison’s 11 firehouses is equipped with a solar hot water system, serving anywhere from 45 percent to 60 percent of the buildings’ collective hot water loads and offsetting 205 tons of carbon dioxide (CO2) emissions each year.
