Electricity usage refers to the amount of electrical energy consumed by devices and appliances in homes, businesses, and industries. It is typically measured in kilowatt-hours (kWh), which indicates how much energy is used over time. Common sources of electricity include power plants, which generate energy from various sources like coal, natural gas, nuclear, and renewable energy such as solar and wind. Understanding electricity usage is important for managing energy costs and promoting efficiency. By monitoring usage patterns, individuals and organizations can identify ways to reduce consumption, such as using energy-efficient appliances or adjusting usage during peak hours. This not only saves money but also helps reduce the environmental impact of energy production.
