The concept of the 'environmental bottom line' in energy use measures primarily refers to how efficiently energy resources are utilized in order to minimize environmental impact. This encompasses evaluating energy efficiency figures or ratios, which provide insight into the effectiveness of energy consumption relative to output or service delivered. High efficiency ratios indicate that less energy is wasted in the process of providing service, thus promoting sustainability and reducing the carbon footprint associated with energy consumption.

While other aspects, such as profit margins, annual consumption statistics, and costs involved in purchasing energy, provide useful information regarding the economic and operational facets of energy use, they do not capture the essence of environmental efficiency. The environmental bottom line focuses on how energy use practices contribute to environmental sustainability, making efficiency figures crucial for assessing and striving towards a more sustainable energy future.
