Assuming that a wireless sensor is installed to determine the state of facilities along a railway, we verified the possibility of applying environmental energy as a power source for the sensor. We measured different types of environmental energy and calculated the potential electric energy that can be generated from each type. The application of different methods of power generation to a wireless sensor power supply was studied on the basis of the calculated amount of power generated. As a result, we found that solar power generation has sufficient potential for this purpose. We also found that power generation methods such as vibration power generation and magnetic field power generation can be applied according to the installation location, the frequency of measurement/communication, and the data collection method used.
