What aspect of embodied energy includes all phases of a product's lifecycle?

The correct answer identifies a crucial component of embodied energy, which encompasses the total energy utilized throughout the entirety of a product's lifecycle. This includes several phases: the energy consumed during extraction of raw materials, the manufacturing processes, transportation to the site, installation, energy used during the product's use, as well as energy spent on disposal or recycling at the end of the product's life.

Addressing the other options: focusing solely on manufacturing energy neglects the additional energy expenditures that occur from the extraction of materials through to disposal, which is not representative of the full scope of embodied energy. Transportation energy also represents just a segment of the lifecycle without considering the energy involved in other phases. Lastly, limiting the focus to the extraction phase ignores significant contributions in later phases, which are integral to understanding the total embodied energy of a product.
