Dalkia
Dalkia is an energy service company, subsidiary of the EDF Group. Its two main businesses consist in making the most of local renewables and unlocking energy savings. Dalkia develops alternative renewables, such as biomass, geothermal, biogas and recovered energies. The company generated €4 billion in revenues in 2017. It has approximately 16,000 employees and has been led by chairwoman and CEO Sylvie Jéhanno since January 2017. History Origins Former logotype before it became a subsidiary of EDF, thumb Dalkia was originally known as the Compagnie Générale de Chauffe (CGC), founded in 1935. In 1967, Chauffage Service (founded in 1944) merged into CGC. In 1980, CGC was acquired by Compagnie Générale des Eau (CGE, later renamed Vivendi in 1998). CGC merged with Groupe Montenay in 1986 to form Compagnie Générale de Chauffe/Groupe Montenay, which was further merged in 1995 to become the Energy Services division of CGE. Creation of Dalkia In 1998, the CGE En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Électricité De France
Électricité de France SA (; ), commonly known as EDF, is a French multinational corporation, multinational electric utility company owned by the government of France. Headquartered in Paris, with €139.7 billion in sales in 2023, EDF operates a diverse portfolio of at least 120 gigawatts of generation capacity in Europe, South America, North America, Asia, the Middle East, and Africa. In 2009, EDF was the world's largest producer of electricity. Its 56 active nuclear reactors in France are spread out over 18 sites (18 nuclear power plants). They comprise 32 reactors of 900 MWe, MWe, 20 reactors of 1,300 MWe, MWe, and 4 reactors of 1,450 MWe, all Pressurized water reactor, PWRs. EDF was created on 8 April 1946 by the 1945 parliament, from the merging of various divided actors. EDF led France's post-war energy growth, with a unique focus on civil nuclear energy, through reconstruction and further industrialization within the ''Trente Glorieuses'', being a flagship of France ...

Vivendi
Vivendi SE (stylized in all lowercase) is a French investment company headquartered in Paris. It currently wholly-owns Gameloft as well as a number of investments in several companies, primarily involved in content, entertainment, media, and telecommunications. In 2000, Vivendi Universal was created from the merger with Canal+ S.A., Groupe Canal+ and Seagram, Seagram Company Ltd., owner of Universal Pictures. Vivendi sold 80% of Universal to the now-defunct General Electric (GE, owner of NBC) in 2004, forming what is now NBCUniversal. In 2006, it sold off most of the Universal components and its name reverted to Vivendi. GE bought out Vivendi's 20% stake in NBCUniversal during Comcast's Acquisition of NBC Universal by Comcast, acquisition of the latter. , Vivendi's chairman Yannick Bolloré is also CEO of Havas, which was spun off from Vivendi in 2000, later became a subsidiary, and was spun off again in 2024. From 2021, Vivendi has spun off its fully-owned assets in order to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Conditioning
Air conditioning, often abbreviated as A/C (US) or air con (UK), is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature, and in some cases, also controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or through other methods, such as passive cooling and ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide Heating, ventilation, and air conditioning, heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners but use a reversing valve, allowing them to both heat and cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used in vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming increasingly common in cool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incineration
Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste and may take the form of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the atmosphere. In some cases, the heat that is generated by incineration can be used to generate electric power. Incineration with energy recovery is one of several waste-to-energy technologies such as gasification, pyrolysis and anaerobic digestion. While incineration and gasification technologies are similar in principle, the energy produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Power
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics (PV) were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar panels has fallen, grid-connected solar PV systems' capacity and production has doubled about every three years. Three-quarters of new generation capacity is solar, with both millions of rooftop installatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cogeneration
Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover otherwise wasted thermal energy for heating. This is also called combined heat and power district heating. Small CHP plants are an example of decentralized energy. By-product heat at moderate temperatures ( can also be used in absorption refrigerators for cooling. The supply of high-temperature heat first drives a gas or steam turbine-powered generator. The resulting low-temperature waste heat is then used for water or space heating. At smaller scales (typically below 1 MW), a gas engine or diesel engine may be used. Cogeneration is also common with geothermal power plants as they often produce relatively low grade heat.

Efficient Energy Use
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, building insulation, insulating a building allows it to use less heating and cooling energy while still maintaining a Thermal comfort, comfortable temperature. Another method made by Lev Levich is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in Green building, buildings, industrial processes and Energy efficiency in transport, transportation could reduce the world's energy needs in 2050 by one third. There are two main motivations to improve energy efficiency. Firstly, one motivation is to achieve Operating cost, cost savings during the operation of the appliance or process. However, installing an energy-efficient technology comes with an upfront cost, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
