Energy efficiency is the practice of using less energy to perform the same task or produce the same result, reducing energy waste and promoting energy savings.

Energy efficiency is essential for reducing greenhouse gas emissions and mitigating climate change.

It is a cost-effective way to reduce energy consumption and lower energy bills.

Energy efficiency can be achieved through various means, including using energy-efficient appliances and optimizing energy use in buildings. Efficiency improvements, such as reducing energy consumption and enhancing the effectiveness of energy use in buildings and appliances, can alleviate stress on the electric grid, contribute to environmental sustainability, and offer financial savings for consumers. To improve energy efficiency, organizations like EERE play a crucial role in facilitating initiatives that yield significant benefits across various sectors.
