Every building, from the smallest school to the tallest skyscraper, uses energy. This energy is mostly derived from the burning of fossil fuels at power plants. These emissions contribute to climate change. In fact, the buildings we see in our communities every day — offices, hospitals, schools, supermarkets, factories, and more — account for half of all energy consumption in the United States at a cost of more than $300 billion per year, more than any other sector of the economy.
Out of all that energy, often up to 30 percent or more is wasted through inefficiencies. Improving energy efficiency is the single largest way to eliminate this waste. Through ENERGY STAR, thousands of organizations nationwide are transforming the way they use energy every day.
