The diagram illustrates the process of producing electricity from one specific type of coal. Overall, there are several steps included in this process, commencing with the coal extraction through mining and culminating in the distribution of produced electricity for consumption. Notably, there is a combination of manual labour and machinery in this process. Focusing on the first half, the coal is mined by workers. Once enough quantity of mined coal is loaded onto a cart, it is fed into a crusher where coal is broken down into small particles. After that, it is shipped via trucks to a gasifier, where the heat is applied to convert the coal into gas, which then moves to the next step. Turning to the remaining steps, the gas released from the previous step passes through a cooling facility, where the waste heat is also released. Subsequently, it is cleaned to remove the impurities and other contaminants from the gas. Finally, it is transferred to the gas power plant, where the electricity is produced alongside the waste heat before being transmitted via power lines for the use by both residential homes and commercial buildings, thereby ending the process.
