Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage (using, for example, the pumped-storage method).. Electricity is not freely available in nature, so it must be "produced" (that is, transforming other ...
Coal is the most abundant fossil fuel on the planet, and widely used as the source of energy in thermal power stations and is a relatively cheap fuel. Coal is an impure fuel and produces more greenhouse gas and pollution than an equivalent amount of petroleum or natural gas. For instance, the operation of a 1000-MWe coal-fired power plant results in a nuclear radiation …

Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the …
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests, woodlands, and associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences.
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions.In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2022, no design …
The CANDU (Canada Deuterium Uranium) is a Canadian pressurized heavy-water reactor design used to generate electric power. The acronym refers to its deuterium oxide (heavy water) moderator and its use of (originally, natural) uranium fuel. CANDU reactors were first developed in the late 1950s and 1960s by a partnership between Atomic Energy of Canada Limited …

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a …
Carbon dioxide (chemical formula CO 2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.It is a trace gas in Earth's atmosphere at 417 …

In physics, energy (from Ancient Greek: ἐνέργεια, enérgeia, "activity") is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
Phosphate fertilizers are obtained by extraction from phosphate rock, which contains two principal phosphorus-containing minerals, fluorapatite Ca 5 (PO 4) 3 F (CFA) and hydroxyapatite Ca 5 (PO 4) 3 OH. These minerals are converted into water-soluble phosphate salts by treatment with sulfuric (H 2 SO 4) or phosphoric acids (H 3 PO 4).The large production of sulfuric acid is …
