The maintenance of the diffuse, ionized gas responsible for the pulsar dispersion measures requires at least 4 x 10 to the -5th ergs/s to 4 x 10 to the -3rd ergs/s per sq cm of Galactic disk, depending upon its electron temperature. Approximately half of the power is for gas at absolute value of z greater than 500 pc. The minimum power requirements are comparable to the total power injected into the diffuse interstellar medium by luminous stars and supernovae, which implies that most of the ionized gas, even at high absolute value of z, is at a temperature near 10,000 K. This gas accounts for at least one-third of the Galactic H-alpha background and must have a volume filling fraction f greater that about 0.2.
