How much electricity is wasted every year?

Globally, it is estimated that around 10% of electricity is wasted due to inefficiencies in generation, transmission, and consumption. This translates to approximately 2,000 terawatt-hours (TWh) annually, enough to power hundreds of millions of homes. In the United States alone, about 60 billion kilowatt-hours are wasted each year, primarily through outdated infrastructure and energy-inefficient appliances. Reducing this waste is crucial for improving energy sustainability and lowering greenhouse gas emissions.
