We have used the Far Ultraviolet Spectroscopic Explorer to search for O VI 1032 Å and C III 977 Å emission from several nearby galaxies with starburst superwinds. No O VI or C III emission was detected, with upper limits less than or equal to the Chandra 0.3-2.0 keV X-ray flux. These observations limit the energy lost through radiative cooling of coronal phase (log T=5.5) gas to roughly the same magnitude as that lost in the hot phase through X-ray emission, which has been shown to be small. The wind material retains most of its energy and may be able to escape from the gravitational potential of the host galaxy, enriching the intergalactic medium with energy and metals. The absence of O VI, and C III emission limits shock velocities in the winds to vs⪉90 km s-1 unless a significant fraction of the Hα emission arises in photoionized gas.
