a hybrid energy control system comprising a primary energy source, a secondary energy source, and an energy management controller operably connected to the primary energy source and the secondary energy source;

an RF communication module; and

a GPS positioning element.

2. The device of claim 1 further comprising a battery.

3. The device of claim 1 wherein the primary energy source comprises at least two energy harvesters and appropriate circuitry.

4. The device of claim 3 wherein the at least two energy harvesters are selected from a piezoelectric element, a photovoltaic cell, and a thermoelectric generator.

5. The device of claim 3 wherein the at least two energy harvesters are individually selected from a piezoelectric element, a photovoltaic cell, and a thermoelectric generator.

6. The device of claim 1 wherein the communication module is a ZigBee, LTE, and/or Low Energy BlueTooth communication module.

7. The device of claim 1 further comprising a cellular communication module.

8. The device of claim 7 wherein the cellular communication module is a CDMA and/or GSM communication module.

9. The device of claim 1 wherein the energy management controller comprises a DC/DC converter or an AC/DC converter.

10. The device of claim 1 wherein the energy management controller comprises a DC/DC converter and an AC/DC converter.

11. A wireless tracking device comprising:

a hybrid energy control system comprising a first energy harvester, a second energy harvester, an energy reservoir operably connected to the first energy harvester and the second energy harvester, and an energy management controller operably connected to the first energy harvester, the second energy harvester, and to the reservoir;

an RF communication module; and

a GPS positioning element.

12. The device of claim 11 wherein the first energy harvester and the second energy harvester are individually selected from a piezoelectric element, a photovoltaic cell, and a thermoelectric generator.

13. The device of claim 11 wherein the RF communication module is a ZigBee, LTE, and/or Low Energy BlueTooth communication module.

14. The device of claim 11 further comprising a cellular communication module.

15. The device of claim 14 wherein the cellular communication module is a CDMA and/or GSM communication module.

16. The device of claim 11 wherein the energy management controller comprises a DC/DC converter and an AC/DC converter.

17. The device of claim 11 further comprising a battery.
