Wind energy harnesses the power of wind using turbines, while coal energy burns pulverized coal in power plants. Wind turbines have little environmental impact and minimal hazards, but some oppose their appearance. Coal has significant negative environmental consequences such as air and water pollution. It also poses health and safety risks to miners and plant workers. While wind turbines have higher initial costs, coal energy has increasing mining expenses and wind power is becoming more affordable over time. Overall, the document concludes wind energy is cleaner, safer, and increasingly cost-competitive compared to coal.
