A megawatt (MW) is a unit of power equal to one million watts, symbolized by “MW,” and is used worldwide to quantify large‑scale energy generation and consumption in fields such as electricity production, renewable energy, and industrial processes; it provides a clear, standardized measure for comparing the output of power plants, the capacity of solar farms, or the demand of massive data centers, making it essential for engineers, policymakers, and investors who need to assess performance, plan infrastructure, and evaluate sustainability goals in both practical applications and scientific research.
