It has also been argued that energy efficiency is only one consideration in deciding which alternative process to employ, and that it should not be elevated to the only criterion for determining environmental acceptability ; for example, simple energy analysis does not take into account the renewability of energy flows or the toxicity of waste products ; however the life cycle assessment does help companies become more familiar with environmental properties and improve their environmental system.
