An energy source for supplying an autonomous electrical load system with electrical energy includes a thermogenerator device configured to generate a thermoelectric voltage to be fed to the electrical load system. The thermogenerator device is under the influence of a temperature difference between a warmer first thermal coupling device and a colder second thermal coupling device. The energy source further includes a microfluidic cooling device having a heat-absorption region, a heat-emission region, and a closed microfluidic circulation system configured to circulate a fluid between the heat-absorption region and the heat-emission region. The heat-absorption region has a thermally conductive connection to the second thermal coupling device. The heat-emission region is configured to be coupled to an external heat sink using a thermally conductive connection such that the circulating fluid carries thermal energy away from the second thermal coupling device and transports the thermal energy to the external heat sink.
