A road building machine 10 (e.g. road finisher, feeder or road miller) comprises: an electric motor as a primary drive assembly; and at least one electrical energy store/accumulator A1-A4 as an energy source for the drive assembly at least. The accumulator(s) is detachably connected to the road building machine and is provided as a replaceable energy store A2-A4, such that an accumulator which is no longer fully charged (i.e. discharged below a defined threshold value) can be replaced by a fully charged accumulator. Plural accumulators may be provided, which are replaceable individually or in combination. An integral accumulator A1 may remain on the road building machine even after being discharged, while a separate, discharged accumulator A2-A4 is replaced by fully charged replaceable accumulator. The integral accumulator may be charged by one or more of: the replaceable accumulators; an additional electrical energy source; or by a charger. A controller in the road building machine may control energy consumption of the accumulators, such that a replaceable accumulator is prioritised for consumption of electrical energy, and energy from the integral accumulator is provided only if some, or all, of the replaceable accumulators are discharged below a defined threshold value. The controller may control the energy consumption of all accumulators such that all are discharged uniformly.
