Small and micro gas turbines are already used in the sort of Combined Heat and Power plants used to power commercial / retail buildings, refrigerated warehouses, light industrial units and the like. There's no reason why they shouldn't be used for residential neighbourhoods, especially in colder areas where district heating would be a major selling point. Compared to reciprocating engine-powered CHP, they tend to produce a slightly higher proportion of their energy output in the form of heat than electricity, and the plant is about about 60% of the volume and half the weight - so they make most sense in constrained spaces or for rooftop installations.
