Energy Supply
Energy supply is the delivery of fuels or transformed fuels to point of consumption. It potentially encompasses the extraction, transmission, generation, distribution and storage of fuels. It is also sometimes called energy flow. This supply of energy can be disrupted by several factors, including imposition of higher energy prices due to action by OPEC or other cartel, war, political disputes, economic disputes, or physical damage to the energy infrastructure due to terrorism. The security of the energy supply is a major concern of national security and energy law. Other uses New York Consolidated Laws includes a statutory code called "Energy Law".N.Y.

Fuel
A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work (physics), work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy, such as Nuclear power, nuclear energy (via nuclear fission and nuclear fusion). The heat energy released by reactions of fuels can be converted into mechanical energy via a heat engine. Other times, the heat itself is valued for warmth, cooking, or industrial processes, as well as the illumination that accompanies combustion. Fuels are also used in the Cell (biology), cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related organic molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized. Fu ...

Energy Conservation
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable energy or energy with more efficiency). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings. Green engineering practices improve the life cycle of the components of machines which convert energy from one form into another. Energy can be conserved by reducing waste and losses, improving efficiency through technological upgrades, improving operations and maintenance, changing users' behaviors through user profiling or user activities, monitoring appliances, shifting load to o ...

World Energy Consumption
World energy supply and consumption refers to the global supply of energy resources and its consumption. The system of global energy supply consists of the energy development, refinement, and trade of energy. Energy supplies may exist in various forms such as ''raw resources'' or ''more processed and refined'' forms of energy. The raw energy resources include for example coal, unprocessed oil and gas, uranium. In comparison, the refined forms of energy include for example refined oil that becomes fuel and electricity. Energy resources may be used in various different ways, depending on the specific resource (e.g. coal), and intended end use (industrial, residential, etc.). Energy production and consumption play a significant role in the global economy. It is needed in industry and global transportation. The total energy supply chain, from production to final consumption, involves many activities that cause a loss of useful energy. As of 2022, energy consumption is still ab ...

Market Transformation
Market transformation describes both a policy objective and a program strategyYork, D. A Discussion and Critique of Market Transformation' , Review 186-1. Energy Center of Wisconsin, June 1999 to promote the value and self-sustaining presence of energy-efficient technologies in the marketplace. It is a strategic process of market intervention which aims to alter market behavior by removing identified barriers and leveraging opportunities to further the internalization of cost-effective energy efficiency as a matter of standard practice. Market transformation has rapidly become the objective of many privately and publicly supported energy efficiency programs in the United States and other countries. Background First coined in a paper presented at the ACEEE Summer Study in 1992,Nadel, Thorne, Sacks, Prindle, Elliott.

List Of Energy Topics
The following outline is provided as an overview of and topical guide to energy: Energy – in physics, this is an indirectly observed quantity often understood as the ability of a physical system to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert force (a pull or a push) against an object that is moving along a definite path of certain length. Forms of energy * Chemical energy – energy contained in molecules * Electrical energy – energy from electric fields * Free energy - energy state function * Geothermal energy – thermal energy extracted from the Earth's crust * Gravitational energy – energy from gravitational fields * Ionization energy – energy that binds an electron to its atom or molecule * Kinetic energy – (), energy of the motion of a body * Magnetic energy – energy from magnetic fields * Mechanical energy – The sum of (usually ...

Introduction To Entropy
In thermodynamics, entropy is a numerical quantity that shows that many physical processes can go in only one direction in time. For example, cream and coffee can be mixed together, but cannot be "unmixed"; a piece of wood can be burned, but cannot be "unburned". The word 'entropy' has entered popular usage to refer to a lack of order or predictability, or of a gradual decline into disorder. A more physical interpretation of thermodynamic entropy refers to spread of energy or matter, or to extent and diversity of microscopic motion. If a movie that shows coffee being mixed or wood being burned is played in reverse, it would depict processes highly improbable in reality. Mixing coffee and burning wood are "irreversible". Irreversibility is described by a law of nature known as the second law of thermodynamics, which states that in an isolated system (a system not connected to any other system) which is undergoing change, entropy increases over time. Entropy does not increase inde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entropy (energy Dispersal)
In thermodynamics, the interpretation of entropy as a measure of energy dispersal has been exercised against the background of the traditional view, introduced by Ludwig Boltzmann, of entropy as a quantitative measure of disorder. The energy dispersal approach avoids the ambiguous term ' disorder'. An early advocate of the energy dispersal conception was Edward A. Guggenheim in 1949, using the word 'spread'.Dugdale, J.S. (1996). ''Entropy and its Physical Meaning'', Taylor & Francis, London, , Dugdale cites only Guggenheim, on page 101.Guggenheim, E.A. (1949), Statistical basis of thermodynamics, ''Research: A Journal of Science and its Applications'', 2, Butterworths, London, pp. 450–454. In this alternative approach, entropy is a measure of energy ''dispersal'' or ''spread'' at a specific temperature. Changes in entropy can be quantitatively related to the distribution or the spreading out of the energy of a thermodynamic system, divided by its temperature. Some educators pr ...

Energy Quality
Energy quality is a measure of the ease with which a form of energy can be converted to useful work or to another form of energy: i.e. its content of thermodynamic free energy. A high quality form of energy has a high content of thermodynamic free energy, and therefore a high proportion of it can be converted to work; whereas with low quality forms of energy, only a small proportion can be converted to work, and the remainder is dissipated as heat. The concept of energy quality is also used in ecology, where it is used to track the flow of energy between different trophic levels in a food chain and in thermoeconomics, where it is used as a measure of economic output per unit of energy. Methods of evaluating energy quality often involve developing a ranking of energy qualities in hierarchical order. Examples: Industrialization, Biology The consideration of energy quality was a fundamental driver of industrialization from the 18th through 20th centuries. Consider for example t ...

Energy Policy
Energy policies are the government's strategies and decisions regarding the Energy production, production, Energy distribution, distribution, and World energy supply and consumption, consumption of energy within a specific jurisdiction. Energy is essential for the functioning of modern economies because they require energy for many sectors, such as industry, transport, agriculture, housing. The main components of energy policy include legislation, international treaties, Energy subsidy, energy subsidies and other public policy techniques. The energy sector emits more greenhouse gas worldwide than any other sector. Therefore, energy policies are closely related to climate policies. These decisions affect how high the greenhouse gas emissions by that country are. Purposes Access to energy is critical for basic social needs, such as lighting, heating, cooking, and healthcare. Given the importance of energy, the price of energy has a direct effect on jobs, economic productivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Derivative
An energy derivative is a derivative contract based on (derived from) an underlying energy asset, such as natural gas, crude oil, or electricity. Energy derivatives are exotic derivatives and include exchange-traded contracts such as futures and options, and over-the-counter (i.e., privately negotiated) derivatives such as forwards, swaps and options. Major players in the energy derivative markets include major trading houses, oil companies, utilities, and financial institutions. Energy derivatives were criticized after the 2008 financial crisis, with critics pointing out that the market artificially inflates the price of oil and other energy providers. Definition The basic building blocks for all derivative contracts are futures contracts and swaps contracts. In energy markets, these are traded on the New York Mercantile Exchange NYMEX, in Tokyo TOCOM and online through the IntercontinentalExchange. Futures contracts A futures contract is an agreement to buy or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Market
An energy market is a type of commodity market on which electricity, heat, and fuel products are traded. Natural gas and electricity are examples of products traded on an energy market. Other energy commodities include: oil, coal, carbon emissions (greenhouse gases), nuclear power, solar energy and wind energy. Due to the difficulty in storing and transporting energy, current and future prices in energy are rarely linked. This is because energy purchased at a current price is difficult (or impossible) to store and then sell at a later date. There are two types of market schemes (for pricing): spot market and forward market. Typically, energy development stems from a government's energy policy which encourages the development of an energy industry specifically in a competitive manner (as opposed to non competitive). Until the 1970s when energy markets underwent dramatic changes, such markets were characterized by monopoly-based organizational structures. For instance, most of the ...
