Sustainable energy sources have great potential for solutions to current and future energy needs. The development of solar energy utilization technology is closely related to optics, photoelectric, and thermal principles. The fluidic, mechanical, and electromagnetic tenets are the basis for developing technology for the use of water and wind energy. Geothermal technology developed in engineering physics includes technologies to improve the performance of the utilization of geothermal energy as the development of low-temperature energy conversion technologies and residual heat energy from residual wastewater (brine). Thermal and electromechanical principles can be applied to the development of technology. Biomass energy technology developed in the field of physical engineering includes technology for the use of biomass materials to be processed into energy, both physically, chemically, and thermally. The principles applied are mass transport physics, chemical reactions, and thermals.
In line with this mindset, groups of elective courses can be arranged that support the development of sustainable energy technology, which includes: water and wind energy system engineering, solar energy system engineering, geothermal energy system engineering, biomass energy system engineering, and sustainable engineering.
