The very diverse geometrical and electronic structures of inorganic clusters, and in particular early-transition metal polyoxometalates (POMs), give these complex polyanions an extensive, usually reversible and tunable redox chemistry. These and other POM properties make them of value in several fields. We have taken advantage of many POM properties to make POM-based (a) water oxidation catalysts (WOCs), (b) water and CO<sub>2</sub> reduction catalysts, (c) redox relays and (d) other functional units important in energy chemistry. We will report (1) hydrolytic and multi-electron-transfer studies of POM WOCs, (2) synthesis and characterization of the first strong-base-stable WOCs, which involve multi-Cu-O clusters stabilized by polyniobates, and (3) Co<sub>9</sub> heteropolytungstates, that are functional in acid solution. The impact of counterion effects on POMs and their catalytic and other properties will be addressed. Progress by many groups on POM catalysts and platforms for solar fuels have been reported since our initial papers in this area (2008 and 2010).
