- Discharge of liquid waste or pollution. Effluents can contain bacteria, viruses, excessive nutrient loads and chemicals that are harmful to wildlife, humans and ecosystems.
- Embodied Energy
- Embodied energy refers to how much energy it takes to make a building material, the energy required to transport the material, and where the material goes at the end of its life.
- Emission
- Pollution discharged into the atmosphere from smokestacks, other vents, and surface areas of commercial or industrial facilities; from residential chimneys; and from motor vehicle, locomotive, or aircraft exhausts.
- Emission Cap
- A limit designed to prevent projected growth in emissions from existing and future stationary sources from eroding any mandated reductions.
- Emission Factor or EF
- The average release rate of a given pollutant for a given source, relative to units of production or activity.
- End-of-the-pipe
- Technologies such as scrubbers on smokestacks and catalytic converters on automobile tailpipes that reduce emissions of pollutants after they have formed.

- The measurement and analysis of energy used by various industrial processes for the purpose of improving energy efficiency.
- Energy Crops
- Crops cultivated specifically for producing energy — particularly electricity or liquid fuels.
- Energy Efficient
- A product, business or project is considered energy efficient if it uses the least amount of mechanical or electrical power and maximizes the use of natural or renewable power sources.
- Energy Footprint
- Energy data that maps the flow of energy supply, demand and losses in manufacturing industries.
- Energy Independence and Security Act of 2007
- Signed into law in 2007 and originally named the Clean Energy Act, this body of laws aims to move the U.S. toward greater energy independence and security.

- The escape or breach of electrical power used for cooling, heating or lighting a building or home.
- Energy Recovery
- Obtaining energy from waste through a variety of processes (e.g. combustion).
- Energy Star Program
- The Energy Star Program aims to entice consumers and businesses to make energy-efficient choices.
- Energy-Saving Lights
- Light sources that use the least amount of electricity and that can also be used for a longer period of time are considered energy-saving lights.
- Environment Impact Assessment or EIA
