What is the purpose of the ENERGY STAR program?

The ENERGY STAR program is primarily designed to establish minimum standards for energy-efficient products, making option C the correct choice. The program, which is a government-backed initiative, aims to help consumers identify products that meet certain energy efficiency criteria. By doing so, it encourages manufacturers to produce more efficient goods, ultimately leading to reduced energy consumption and lower greenhouse gas emissions.

Additionally, the ENERGY STAR label serves as a trusted certification that informs consumers about the environmental performance of a product, thereby promoting energy conservation. This initiative is essential for both residential and commercial sectors, influencing purchasing decisions and guiding consumers toward eco-friendly alternatives.

Other options, such as providing loans or tracking credit history, do not align with the goals or functions of the ENERGY STAR program. Similarly, promoting union activities in energy sectors is unrelated to the focus of the program, which prioritizes energy efficiency over labor relations.
