What is a unitary process
Glossary: environmental sciences
The following glossary provides a small selection of environmentally relevant terms. The definitions were taken from various sources on the Internet and revised. Legal terms refer in almost all cases to the situation in the FRG. A website with a very extensive collection of on-line lexicons, glossaries and dictionaries on the topics can be found at:
You can find additional articles on a number of key words on the website of the Internet encyclopedia Wikipedia.
The glossary is currently under construction and will be expanded further.

Definition according to ISO standard: substance or energy that is supplied to the examined product system or unit process and has been removed from the environment without prior treatment by humans.
Substance or energy that leaves the product system or unit process to be examined and is released into the environment without subsequent treatment by humans.
Release of substances (gases, aerosols, dusts) or energy (radiation, heat, noise) into the environment (atmosphere).
a measure of the energy per volume of a material (volumetric energy density, unit joule / m3) or a measure of the energy per mass of a substance (gravimetric energy density, unit Joule / g). -> more
Energy payback time
The time in which a power plant has generated the same amount of electrical energy as is used to build and operate it.
The discharge time indicates the period of time for which a storage system can supply electricity before it has to be charged again.
The harvest factor of a power plant describes the ratio of the useful energy released during its production time to the energy used for construction and operation. -> more
According to ISO standard: Quantified benefit of a product system for use as a reference unit (reference value) in a life cycle assessment study.
Global warming describes the current increase in global warmth, which can be seen, among other things, in the measurable increase in the global average temperature. -> more

Life cycle assessment
English term for life cycle assessment.
In connection with a life cycle assessment according to ISO standard: Smallest part of a product system for which data is collected in order to create a life cycle assessment.
Life cycle assessment
A life cycle assessment is a method with which the effects of a product on the environment can be estimated. Life stages, raw material extraction, production, processing, transport, use, reuse and disposal are examined for their environmental relevance. There are no uniform agreements with regard to the method, criteria and weighting of the criteria. In addition, life cycle assessments do not inquire about the benefits of a product, as e.g. product line analysis does.
Statistical term that describes the area that cities actually need for their supply and disposal.
According to ISO standard: substance or energy that is emitted by a process. Note: Substances can include raw materials, intermediates, P te / services, emissions and waste.
Electricity generation using solar cells.
Product line analysis
A product line analysis (PLA) is a life cycle assessment that also shows the social and societal aspects of a product. It assesses a product with regard to all effects of the procurement of raw materials, its manufacture, its processing, its transport, its use and its recycling or its disposal. -> more
According to ISO standard: Summary of the processes linked by material and energy flows that fulfill one or more defined functions.
A synonym for product system in the life cycle assessment.
pumped storage power plant
A pumped storage power plant is a special form of a storage power plant and is used to store electrical energy by pumping up water. -> more
Pyrolysis is a thermo-chemical breakdown of organic compounds, whereby high temperatures (500-900 C) force a bond break within large molecules into smaller ones. -> more
Replacement of old wind turbines with new, more powerful ones at the same location.
Qualitative and quantitative definition of hazards and the derivation of action plans to avoid environmental damage or to combat it effectively.
Grate firing is an incineration process in waste incineration plants. It is a solid fuel furnace in which the fuel burns lying on a grate, a support surface provided with openings. -> more
Rotating component of a wind turbine, consisting of rotor blades and a hub.
Black start ability
The black start capability describes the property of a storage system to be able to start up from the switched-off state and provide energy without additional electrical energy. This property is particularly important in the event of total power outages.
The self-discharge rate indicates what percentage of the stored energy is lost without active extraction per hour or per day. This variable becomes more relevant the longer the energy is to be stored.
Ready-to-assemble system for generating solar power, consisting of a large number of interconnected solar cells in a solid, weatherproof frame.
Solar thermal power plant
System for generating electricity, in which a heat transfer medium is heated by solar energy in order to subsequently drive an engine (e.g. steam turbine, Stirling).
Semiconductor that converts radiant energy into electricity.
Storage power plant
Storage power plants use water from a reservoir to produce electricity. To dam the water, dams (dams, dams) have to be built. -> more
Electricity storage capacity
The electricity storage capacity indicates how much electrical charge, in ampere-hours, Ah, can be stored in a battery.
Environmental impact assessment
Thin plate made of semiconductor material from which solar cells are made.
Vienna Construction Noise Act
Electronic component that converts the direct current from the solar modules into grid-compatible alternating current.
Also referred to as wind classes (taken from English) Not to be confused with the wind force. The wind speed divides the range of mean wind speeds (annual mean) into 7 classes depending on the height above ground. It serves as an evaluation criterion for the construction of wind power plants.
Fluidized bed combustion
The fluidized bed furnace is a furnace with which crushed fuel can be burned in a fluidized bed made of hot bed material (e.g. sand). -> more
The efficiency indicates what percentage of the energy supplied to the storage system is available again after storage. It describes the relationship between the power delivered and the power consumed.
Vienna Environmental Noise Protection Ordinance
