A megawatt (MW) is a unit of power equal to one million watts. It is commonly used to measure the output of large power plants, such as those that generate electricity from coal, natural gas, or renewable sources like solar and wind. One megawatt can power approximately 800 to 1,000 homes, depending on their energy consumption. In the context of electricity, a megawatt is often used to describe the capacity of generators and the amount of energy produced or consumed over time. For example, a megawatt-hour (MWh) represents the energy produced by a megawatt of power running for one hour. This measurement helps utilities and consumers understand energy usage and production levels.
