-          Depletion of fossil fuels, irresponsible and inefficient utilization of energy, and consequent adverse impacts on the environment are current global concerns. These concerns have led to global awareness of renewable generation and sustainable utilization of energy in an attempt to reduce the reliance on oil, coal, and gas to generate electricity. Consequently, billions of dollars are being invested worldwide in energy-related research and development projects searching for efficient, cost-effective, and reliable technologies. Fueled by the significant investments made in the energy sector, the global renewable energy capacity has steadily increased over the last decade. To further promote the widespread use of renewable energy, effective new technologies such as decentralized energy generation (DEG), smart houses, and smart grids have been introduced recently. However, these new technologies essentially require some form of smart monitoring as well as control subsystems to allow for the efficient generation and sustainable use of energy.

           This project aims to design and develop an energy monitor that may be used in a smart house to measure and display the amount of energy consumed by appliances, thereby enabling better management and utilization of renewable energy. During this project, students will be working as part of a design team of four, who will undertake an investigation and subsequently design and develop an energy monitor.
