How much energy do we waste per year?

Globally, it is estimated that about one-third of all energy produced is wasted, amounting to roughly 1,000 terawatt-hours annually. In the United States alone, approximately 30% of energy consumption is considered wasted, primarily due to inefficiencies in buildings, transportation, and industrial processes. This waste not only represents a significant loss of resources but also contributes to increased greenhouse gas emissions. Reducing energy waste is crucial for improving sustainability and enhancing energy efficiency.
