Agency for the Promotion and Rational Use of Energy.
Biomass
The total mass of living matter of plant or animal origin within a given unit of environmental area. Biomass used as renewable energy sources include wood by-products, industrial by- products ( including paper and agro-food industries) agricultural products and by-products, animal by-products as well as urban waste (sewage bio solids, household refuse, landfills, etc.).
CRED
Center for Renewable Energy Development.
Co-generation
Combined heat and power generation. The advantage of cogeneration compared to traditional generation methods is that it improves energy efficiency. This means that to equivalent energy consumption, the plant using cogeneration will recover more energy at the output than the single power plant.
CREDEG
Electricity and Gas Research and Development Center, subsidiary company of Sonelgaz Group.
Sustainable development
Development that meets current needs without jeopardizing the ability of future generations to meet own needs.
Fossil energy
Fossil energy is the chemical energy contained in fossil fuels. Over geologic time, organic matter (biomass) was buried deep within the ground or formed deposits on the bottom of lakes and oceans. It then turned into kerogen, then into fossil fuels: oil, natural gas or coal.
Renewable energies
Renewable energies are referred to as the whole set of energy production technologies which, if implemented, do not lead to the depletion of the initial resource which is renewable permanently at human scale. Provided by the sun, the wind, the heat from the earth, the waterfalls, the tides or yet the growth of plants, their exploitation generate little or no waste and no polluting emissions. They are energies generated from a permanent renewable source. They are called “flow” energy sources compared with «stock» energy sources, which are made of limited deposits of fossil fuels: oil, coal, gas and uranium.
Hydropower
Hydropower is the power that is derived from the energy of moving an incompressible fluid like fresh or sea water. The motion will generate a mechanical force that is either used directly or converted into electric power.
Wind energy
Energy generated from wind by the rotation of propellers or blades (turbines). The energy produced depends on the wind and therefore a random weather factor. There are ground and sea facilities (offshore wind turbines). Wind farm: group of wind turbines producing electricity. A farm may include less than a dozen to several hundred wind turbines.
NFEE
NG fuel
Natural Gas fuel.
LPG fuel
Liquefied Petroleum Gas fuel.
Sonelgaz Group
The group of companies called Sonelgaz Group comprises the holding company «Sonelgaz» and 35 subsidiaries, including those in charge of electricity production, transmission and distribution and natural gas transport and distribution.
IAER
Algerian Institute for Renewable Energies and Energy Efficiency.
Kilowatt hour (kWh)
Unit of work and energy measurement. One kilowatt hour corresponds to the consumption of an electric appliance of 1 000 W at work during one hour. 1 MWh (megawatt hour) = 1 000 kWh, 1 TWh (terawatt hour) = 1 billion kWh.
Megawatt (MW)
A megawatt is a unit for measuring power that generally describes the production capacity of a power generator (1 megawatt = 1 million watts).
Photovoltaic module
Assembly of photovoltaic cells with a protective coating and electrically connected. This assembly of cells can generate direct electrical current in individual facilities or in photovoltaic power plants.
The performance metrics of this type of generator are as follows: panel surface and sun radiation level (which varies by region, season, time of day, weather, etc.).
The advantage of photovoltaic solar modules is that they do not generate any waste during operation and can be easily removed when they reach end of life - which is currently about 20 years.
Rouiba Eclairage
Subsidiary company of Sonelgaz Group, which produces lighting equipment and is responsible for implementing a photovoltaic cell manufacturing plant to be operationalized in late 2013.
Silicon
Semiconductor material, which the essential constituent of certain types of sand and computer chips. It can be used in the manufacturing of photovoltaic solar cells and is the component that makes high energy efficiency possible.
NEAL
New Energy Algeria is a joint-stock company, a subsidiary of the groups Sonelgaz, Sonatrach and SIM. Created in 2002, NEAL is in charge of the development of REn projects.
SIM
Semolina Manufacturer of the Mitidja.
Sonatrach
Company of hydrocarbons occurring in the exploration, the production, the transport by pipes, the transformation and the marketing of hydrocarbons and their by-products.
Photovoltaic solar energy
Renewable energy using the radiation of the sun to produce some electricity.
Thermal solar energy
The thermal solar energy allows producing some heat (in low, average or high temperature). The most wide-spread applications are the ones concerning.
VAT
Value Added Tax.
UDTS
Silicon Technology Development Unit.
Watt (W)
The watt (symbol: W) is the international legal unit for power. It corresponds to the amount of energy consumed or produced per unit of time, that is to say one joule per second. In electricity, the watt is the unit of power of a system supplying a current of 1 ampere at a voltage of 1 volt. This word originates from the name of the engineer James Watt.
Watt-peak (Wp)
The Watt-peak is a unit for the measurement of the nominal power delivered by a solar energy device with a standard solar radiation level of 1kW/m² and a temperature of 25°C. This unit makes it possible to compare the various solar energy collection equipment using photovoltaic materials.
