Energy consumption is unavoidable in man's daily life. Energy needs to be transformed from one form to another in order to accomplish any work in life. In the present scenario, green energy is currently in demand. The way that energy used is a sign of how well a country is doing economically. Information displays that the majority of energy used comes from traditional energy sources, which are limited and include fossil fuels, gas, and oil. They are harming our environment by burning fossil fuels. With the available conventional energy supplies, it is challenging to meet the demand. Therefore, using green or non-conventional energy may be the greatest option to meet the current demand. The goal of this work is to create a speed break electricity generator that operates the capacity for energy of a heavy vehicle on a speed breaker that energy can then store in the form of compressed air is kept on hand for storage and used for a variety of tasks like street light, traffic signal etc. in smart city applications. We described the mechanism for compressing air in store tanks and generating electricity from compressed air at various stages of the project's development.
