Energy efficiency Using less energy to provide the same service.
ENERGY STAR A US Environmental Protection Agency voluntary program that
helps businesses and individuals save money and protect our climate through
superior energy efficiency.
Energy (a) In engineering physics, energy is the quantitative property that must be
transferred to an object in order to perform work on, or to heat, the object.
(b) Energy is a conserved quantity; the law of conservation of energy states that
energy can be converted in form, but not created or destroyed. (c) Energy is the
power derived from the utilization of physical or chemical resources, especially to
provide light and heat or to work machines.
Engineering It is a professional field involving the use of science and mathematics
to invent, create, design, develop, or improve technologies.
Engineers Without Borders: USA It is a nonprofit organization established to
partner with developing communities in order to improve their quality of life.
Enhanced biological phosphorus removal (EBPR) The process of phosphorus
removal in wastewater that relies on the proliferation and selection of a microbiological population capable of storing phosphorus in excess of their normal
growth requirements. Also called biological nutrient removal (BNR).
Enhanced greenhouse effect The concept that the natural greenhouse effect has
been enhanced by increased atmospheric concentrations of greenhouse gases
(such as CO 2 and methane) emitted as a result of human activities. These added
greenhouse gases cause the Earth to warm.
Enteric fermentation Livestock, especially cattle, produce methane as part of their
digestion. This process is called enteric fermentation, and it represents one-third
of the emissions from the agriculture sector.
Environmental engineering It is a professional engineering discipline that takes
from broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will
protect and also improve the health of living organisms and improve the quality
of the environment. Environmental engineering is a subdiscipline of civil engineering, chemical engineering, and mechanical engineering.
Environmental remediation (a) It is a means of dredging that is beneficial to both
recreational users and natural wildlife habitats. The natural flow of sediments and
industrial runoff can often choke off channels that feed fresh water to inland
wetlands or ponds. Dredging these channels allows water to circulate in and out
of these inland sites, bringing in nutrients and flushing out waste. (b) It is an
action of pollution control that is beneficial to both people and ecological system.
Environmental resource management It is the management of the interaction and
impact of human societies on the environment. It is not, as the phrase might
suggest, the management of the environment itself. Environmental resources
management aims to ensure that ecosystem services are protected and maintained
for future human generations, and also maintain ecosystem integrity through
considering ethical, economic, and scientific (ecological) variables. Environmental resource management tries to identify factors affected by conflicts that arise
