E-Diesel
A mixture of diesel and bioethanol which, with an additive to enhance its stability and improve its lubrication properties and cetane index, can be used in standard diesel engines without significant modifications.
Ecotax or environmental tax
Tax with a potentially positive environmental impact, such as tax on transport or other sources of pollution.
EER
Energy efficiency ratio of a refrigerating machine driven by electric motors. It is equal to the ratio between the heat power delivered by the machine to the transport fluid and the useful power absorbed. It has no units.
Efficient detergents
Nowadays there are some very efficient –and even environmentally friendly– detergents on the market, but you need to read and follow the instructions on the pack. For example, most include cleaning agents that are active at a temperature of 30ºC, hence it is important to wash at this temperature.
Electric power station
Electric power station that takes advantage of a heat source to give place to the steam obtaining, which later drives a turbine with a generator to produce electricity. If the heat comes from the combustion or burning fuel, he is named a thermal conventional head office(plant); and if the heat has a radioactive origin, nuclear power station. In the practice, when one speaks about thermal head offices(plants) one refers to the first ones.
Electricity plant
Any installation dedicated to electricity generation.
Electronic management
Electrical appliances that incorporate electronic systems to manage the processes they carry out are more energy efficient.
Electronically controlled lights
A type of low energy consumption light that is turned on using an electronic reactance rather than an electromagnetic one. This makes them more energy efficient.
Energy balance
Application of the principle of energy conservation to a particular system whereby all the energy inputs and losses are determined empirically by means of calculations. This type of system is a useful way of defining a system and identifying the stages in which the process can be improved.
Energy crop
Crop such as thistles, grown to produce biomass that can be used as a source of energy, either directly or after conversion to a biofuel.
Energy Efficiency
Set of programmes and strategies to reduce the amount of energy used by particular devices and systems without affecting the quality of the services provided.
Energy labelling system for household appliances
European Directive 92/75/EEC, 22 September 1992, set up a uniform system for all Member States whereby household appliances can be compared with others of their type offering similar features. The aim is to increase the range of information available to consumers about the appliance they are going to use.
Energy Saving
It is possible to save energy in the home both by using more energy efficient appliances and by adopting more responsible habits when using energy-consuming equipment.
Energy Star
Programme introduced in 1992 by the US Environmental Protection Agency (EPA). Energy Star is a voluntary labelling programme which aims to identify and promote energy-saving products so as to cut down on pollution.
Environmental impact
Environmental change over time or in space caused by human activity.
European Directives
These are legal documents issued by the European Council which guide legislation in each Member State so that it is harmonised across the European Union. Their content is not automatically applicable, but they oblige the government of each Member State to implement them in their national legislation within two years.
