The EPA Energy Star for industry to improve energy efficiency helped the car industry, by reducing fossil fuel consumption with 12 percent and emissions of greenhouse gases by more than 700,000 tones of carbon dioxide.
ENERGY STAR program has been designed to educate manufacturers on measures to improve their energy efficiency. To enable manufacturers to judge their performance targets for energy and improve energy efficiency, a number of tools, known as Energy Star Performance Indicators (EPI) have been developed.
EPI is a statistical model of energy consumption at the factory level which allows comparison across sites with different levels and types of production.
Epi is designed to identify ‘’the best of industry’’, in energy performance, a energy performance score is assigned to the installation on a scale of 1-100.
The Duke University report states that: “Electricity use per vehicle in the best plants improved by 2%, while the fuel use per vehicle improved a dramatic 12%. These changes resulted in a reduction of 696 million pounds of carbon dioxide (CO2) emissions at the plants used for this study. The range of performance in fuel use has also narrowed over time, implying that other plants have been catching up to the best-in-class plants. This catching up contributes a reduction of another 766 million pounds of CO2, for a total reduction of nearly 1.5 billion pounds of CO2.”
