The organization's members collectively employ more than 150,000 people and generate billions in economic activity each year. The Alberta Enterprise Group's Board of Directors is mainly composed of prominent executives from oil and gas corporations in Alberta. As of July 2023,
266-548: A basal metabolic rate of 80 watts. For example, if our bodies run (on average) at 80 watts, then a light bulb running at 100 watts is running at 1.25 human equivalents (100 ÷ 80) i.e. 1.25 H-e. For a difficult task of only a few seconds' duration, a person can put out thousands of watts, many times the 746 watts in one official horsepower. For tasks lasting a few minutes, a fit human can generate perhaps 1,000 watts. For an activity that must be sustained for an hour, output drops to around 300; for an activity kept up all day, 150 watts
399-462: A battery (from chemical energy to electric energy ), a dam (from gravitational potential energy to kinetic energy of moving water (and the blades of a turbine ) and ultimately to electric energy through an electric generator ), and a heat engine (from heat to work). Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving
532-463: 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; matter and energy may also be converted to one another. The unit of measurement for energy in the International System of Units (SI)
665-435: A Lagrangian; for example, dissipative systems with continuous symmetries need not have a corresponding conservation law. In the context of chemistry , energy is an attribute of a substance as a consequence of its atomic, molecular, or aggregate structure. Since a chemical transformation is accompanied by a change in one or more of these kinds of structure, it is usually accompanied by a decrease, and sometimes an increase, of
798-474: A biological cell or organelle of a biological organism. Energy used in respiration is stored in substances such as carbohydrates (including sugars), lipids , and proteins stored by cells . In human terms, the human equivalent (H-e) (Human energy conversion) indicates, for a given amount of energy expenditure, the relative quantity of energy needed for human metabolism , using as a standard an average human energy expenditure of 12,500 kJ per day and
931-509: A bound system is discrete (a set of permitted states, each characterized by an energy level ) which results in the concept of quanta . In the solution of the Schrödinger equation for any oscillator (vibrator) and for electromagnetic waves in a vacuum, the resulting energy states are related to the frequency by Planck's relation : E = h ν {\displaystyle E=h\nu } (where h {\displaystyle h}
1064-417: A core concept. Work , a function of energy, is force times distance. This says that the work ( W {\displaystyle W} ) is equal to the line integral of the force F along a path C ; for details see the mechanical work article. Work and thus energy is frame dependent . For example, consider a ball being hit by a bat. In the center-of-mass reference frame, the bat does no work on
1197-492: A crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. The Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that itself (since it still contains
1330-552: A few exceptions, like those generated by volcanic events for example. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, suddenly give up some of their thermal energy to power a few days of violent air movement. In a slower process, radioactive decay of atoms in the core of the Earth releases heat. This thermal energy drives plate tectonics and may lift mountains, via orogenesis . This slow lifting represents
1463-517: A few fossils are the Belly River Group and St. Mary River Formations of the southwest and the northwestern Wapiti Formation , which contains two Pachyrhinosaurus bone beds. The Bearpaw Formation represents strata deposited during a marine transgression . Dinosaurs are known from this formation, but represent specimens washed out to sea or reworked from older sediments . Paleo-Indians arrived in Alberta at least 10,000 years ago, toward

In 2016, Alberta continued to have the youngest population among the provinces with a median age of 36.7 years, compared with the national median of 41.2 years. Also in 2016, Alberta had the smallest proportion of seniors (12.3%) among the provinces and one of the highest population shares of children (19.2%), further contributing to Alberta's young and growing population. About 81% of
1862-477: A kind of gravitational potential energy storage of the thermal energy, which may later be transformed into active kinetic energy during landslides, after a triggering event. Earthquakes also release stored elastic potential energy in rocks, a store that has been produced ultimately from the same radioactive heat sources. Thus, according to present understanding, familiar events such as landslides and earthquakes release energy that has been stored as potential energy in
1995-530: A land area of 634,658.27 km (245,042.93 sq mi), it had a population density of 6.7/km in 2021. Statistics Canada estimated the province to have a population of 4,800,768 in Q1 of 2024. Since 2000, Alberta's population has experienced a relatively high rate of growth, mainly because of its burgeoning economy. Between 2003 and 2004, the province had high birthrates (on par with some larger provinces such as British Columbia), relatively high immigration, and
2128-410: A part of the province's identity. Since Alberta is the province most rich in hydrocarbons, it provides 70% of the oil and natural gas produced on Canadian soil. In 2018, Alberta's output was CA$ 338.2 billion, 15.27% of Canada's GDP. Until the 1930s, Alberta's political landscape consisted of two major parties: the centre-left Liberals and the agrarian United Farmers of Alberta . Today, Alberta
2261-477: A semi-arid steppe climate because the annual precipitation is less than the water that evaporates or is used by plants . The southeastern corner of Alberta, part of the Palliser Triangle , experiences greater summer heat and lower rainfall than the rest of the province, and as a result, suffers frequent crop yield problems and occasional severe droughts. Western Alberta is protected by the mountains and enjoys
2394-558: A study calling for reforms to provincial labour laws , hoping to create good business climates while upholding the collective bargaining rights of workers. The paper argued that the Canada's labour laws lag behind Europe , Australia and the United Kingdom . Some of the recommendations in the study included: having membership cards instead of signing petitions; requiring a quorum, and allowing unionized workers in Alberta be allowed opt out of
2527-425: A system. This property is responsible for the inertia and strength of gravitational interaction of the system ("mass manifestations"), and is also responsible for the potential ability of the system to perform work or heating ("energy manifestations"), subject to the limitations of other physical laws. In classical physics , energy is a scalar quantity, the canonical conjugate to time. In special relativity energy
2660-426: A tiny fraction of the original chemical energy is used for work : It would appear that living organisms are remarkably inefficient (in the physical sense) in their use of the energy they receive (chemical or radiant energy); most machines manage higher efficiencies. In growing organisms the energy that is converted to heat serves a vital purpose, as it allows the organism tissue to be highly ordered with regard to
2793-585: A tributary of the Mackenzie River . Alberta's capital city, Edmonton , is at about the geographic centre of the province. It is the most northerly major city in Canada and serves as a gateway and hub for resource development in northern Canada. With its proximity to Canada's largest oil fields, the region has most of western Canada's oil refinery capacity. Calgary is about 280 km (170 mi) south of Edmonton and 240 km (150 mi) north of Montana, surrounded by extensive ranching country. Almost 75% of

In southwestern Alberta, the cold winters are frequently interrupted by warm, dry Chinook winds blowing from the mountains, which can propel temperatures upward from frigid conditions to well above
3059-478: Is a derived unit that is equal to the energy expended, or work done, in applying a force of one newton through a distance of one metre. However energy can also be expressed in many other units not part of the SI, such as ergs , calories , British thermal units , kilowatt-hours and kilocalories , which require a conversion factor when expressed in SI units. The SI unit of power , defined as energy per unit of time,
3192-460: Is about the maximum. The human equivalent assists understanding of energy flows in physical and biological systems by expressing energy units in human terms: it provides a "feel" for the use of a given amount of energy. Sunlight's radiant energy is also captured by plants as chemical potential energy in photosynthesis , when carbon dioxide and water (two low-energy compounds) are converted into carbohydrates, lipids, proteins and oxygen. Release of
3325-434: Is also a scalar (although not a Lorentz scalar but a time component of the energy–momentum 4-vector ). In other words, energy is invariant with respect to rotations of space , but not invariant with respect to rotations of spacetime (= boosts ). Energy may be transformed between different forms at various efficiencies . Items that transform between these forms are called transducers . Examples of transducers include
3458-558: Is called the Lagrangian , after Joseph-Louis Lagrange . This formalism is as fundamental as the Hamiltonian, and both can be used to derive the equations of motion or be derived from them. It was invented in the context of classical mechanics , but is generally useful in modern physics. The Lagrangian is defined as the kinetic energy minus the potential energy. Usually, the Lagrange formalism
3591-473: Is defined in terms of the energy operator (Hamiltonian) as a time derivative of the wave function . The Schrödinger equation equates the energy operator to the full energy of a particle or a system. Its results can be considered as a definition of measurement of energy in quantum mechanics. The Schrödinger equation describes the space- and time-dependence of a slowly changing (non-relativistic) wave function of quantum systems. The solution of this equation for

In this system
3857-508: Is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen). The nuclear fusion of hydrogen in the Sun also releases another store of potential energy which was created at the time of the Big Bang . At that time, according to theory, space expanded and

4256-617: Is mathematically more convenient than the Hamiltonian for non-conservative systems (such as systems with friction). Noether's theorem (1918) states that any differentiable symmetry of the action of a physical system has a corresponding conservation law. Noether's theorem has become a fundamental tool of modern theoretical physics and the calculus of variations. A generalisation of the seminal formulations on constants of motion in Lagrangian and Hamiltonian mechanics (1788 and 1833, respectively), it does not apply to systems that cannot be modeled with
4389-402: Is no friction or other losses, the conversion of energy between these processes would be perfect, and the pendulum would continue swinging forever. Energy is also transferred from potential energy ( E p {\displaystyle E_{p}} ) to kinetic energy ( E k {\displaystyle E_{k}} ) and then back to potential energy constantly. This
4522-415: Is referred to as conservation of energy. In this isolated system , energy cannot be created or destroyed; therefore, the initial energy and the final energy will be equal to each other. This can be demonstrated by the following: The equation can then be simplified further since E p = m g h {\displaystyle E_{p}=mgh} (mass times acceleration due to gravity times
4655-692: Is the Planck constant and ν {\displaystyle \nu } the frequency). In the case of an electromagnetic wave these energy states are called quanta of light or photons . When calculating kinetic energy ( work to accelerate a massive body from zero speed to some finite speed) relativistically – using Lorentz transformations instead of Newtonian mechanics – Einstein discovered an unexpected by-product of these calculations to be an energy term which does not vanish at zero speed. He called it rest energy : energy which every massive body must possess even when being at rest. The amount of energy

Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field ), the elastic energy stored in a solid object, chemical energy associated with chemical reactions , the radiant energy carried by electromagnetic radiation , the internal energy contained within a thermodynamic system , and rest energy associated with an object's rest mass . All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are driven primarily by radiant energy from

The daily 1500–2000 Calories (6–8 MJ) recommended for a human adult are taken as food molecules, mostly carbohydrates and fats, of which glucose (C 6 H 12 O 6 ) and stearin (C 57 H 110 O 6 ) are convenient examples. The food molecules are oxidized to carbon dioxide and water in the mitochondria C 6 H 12 O 6 + 6 O 2 ⟶ 6 CO 2 + 6 H 2 O {\displaystyle {\ce {C6H12O6 + 6O2 -> 6CO2 + 6H2O}}} C 57 H 110 O 6 + ( 81 1 2 ) O 2 ⟶ 57 CO 2 + 55 H 2 O {\displaystyle {\ce {C57H110O6 + (81 1/2) O2 -> 57CO2 + 55H2O}}} and some of
9975-403: The climate to the southwest, which disrupts the flow of the prevailing westerly winds and causes them to drop most of their moisture on the western slopes of the mountain ranges before reaching the province, casting a rain shadow over much of Alberta. The northerly location and isolation from the weather systems of the Pacific Ocean cause Alberta to have a dry climate with little moderation from
10108-451: The complex organisms can occupy ecological niches that are not available to their simpler brethren. The conversion of a portion of the chemical energy to heat at each step in a metabolic pathway is the physical reason behind the pyramid of biomass observed in ecology . As an example, to take just the first step in the food chain : of the estimated 124.7 Pg/a of carbon that is fixed by photosynthesis , 64.3 Pg/a (52%) are used for
10241-553: The concept of special relativity. In different theoretical frameworks, similar formulas were derived by J.J. Thomson (1881), Henri Poincaré (1900), Friedrich Hasenöhrl (1904) and others (see Mass–energy equivalence#History for further information). Part of the rest energy (equivalent to rest mass) of matter may be converted to other forms of energy (still exhibiting mass), but neither energy nor mass can be destroyed; rather, both remain constant during any process. However, since c 2 {\displaystyle c^{2}}
10374-399: The conservation of energy is a consequence of the fact that the laws of physics do not change over time. Thus, since 1918, theorists have understood that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time. In the International System of Units (SI), the unit of energy is the joule . It
10507-418: The dry prairie of the southeast. The northern and western parts of the province experience higher rainfall and lower evaporation rates caused by cooler summer temperatures. The south and east-central portions are prone to drought-like conditions sometimes persisting for several years, although even these areas can receive heavy precipitation, sometimes resulting in flooding. In the winter, the Alberta clipper ,
10640-515: The end of the last ice age . They are thought to have migrated from Siberia to Alaska on a land bridge across the Bering Strait and then possibly moved down the east side of the Rocky Mountains through Alberta to settle the Americas . Others may have migrated down the coast of British Columbia and then moved inland. Over time they differentiated into various First Nations peoples, including
10773-470: The energy is used to convert ADP into ATP : The rest of the chemical energy of the carbohydrate or fat are converted into heat: the ATP is used as a sort of "energy currency", and some of the chemical energy it contains is used for other metabolism when ATP reacts with OH groups and eventually splits into ADP and phosphate (at each stage of a metabolic pathway , some chemical energy is converted into heat). Only
10906-457: The energy stored during photosynthesis as heat or light may be triggered suddenly by a spark in a forest fire, or it may be made available more slowly for animal or human metabolism when organic molecules are ingested and catabolism is triggered by enzyme action. All living creatures rely on an external source of energy to be able to grow and reproduce – radiant energy from the Sun in the case of green plants and chemical energy (in some form) in
11039-624: The exception of the semi-arid climate of the steppe in the south-eastern section, the province has adequate water resources . There are numerous rivers and lakes in Alberta used for swimming, fishing and a range of water sports. There are three large lakes, Lake Claire (1,436 km [554 sq mi]) in Wood Buffalo National Park, Lesser Slave Lake (1,168 km [451 sq mi]), and Lake Athabasca (7,898 km [3,049 sq mi]), which lies in both Alberta and Saskatchewan. The longest river in
11172-489: The first time in the work of Aristotle in the 4th century BC. In contrast to the modern definition, energeia was a qualitative philosophical concept, broad enough to include ideas such as happiness and pleasure. In the late 17th century, Gottfried Leibniz proposed the idea of the Latin : vis viva , or living force, which defined as the product of the mass of an object and its velocity squared; he believed that total vis viva
11305-516: The freezing point in a very short period. During one Chinook recorded at Pincher Creek , temperatures soared from −19 to 22 °C (−2 to 72 °F) in just one hour. The region around Lethbridge has the most Chinooks, averaging 30 to 35 Chinook days per year. Calgary has a 56% chance of a white Christmas , while Edmonton has an 86% chance. After Saskatchewan, Alberta experiences the most tornadoes in Canada with an average of 15 verified per year. Thunderstorms, some of them severe, are frequent in
11438-413: The height) and E k = 1 2 m v 2 {\textstyle E_{k}={\frac {1}{2}}mv^{2}} (half mass times velocity squared). Then the total amount of energy can be found by adding E p + E k = E total {\displaystyle E_{p}+E_{k}=E_{\text{total}}} . Energy gives rise to weight when it
11571-405: The hundreds of small lakes that dot northern Alberta. Eagles , hawks , owls, and crows are plentiful, and a huge variety of smaller seed and insect-eating birds can be found. Alberta, like other temperate regions, is home to mosquitoes , flies , wasps , and bees. Rivers and lakes are populated with pike , walleye , whitefish , rainbow , speckled , brown trout , and sturgeon . Native to
11704-482: The marginalia of her French language translation of Newton's Principia Mathematica , which represented the first formulation of a conserved measurable quantity that was distinct from momentum , and which would later be called "energy". In 1807, Thomas Young was possibly the first to use the term "energy" instead of vis viva , in its modern sense. Gustave-Gaspard Coriolis described " kinetic energy " in 1829 in its modern sense, and in 1853, William Rankine coined
11837-424: The mass equivalent of an everyday amount energy is minuscule, which is why a loss of energy (loss of mass) from most systems is difficult to measure on a weighing scale, unless the energy loss is very large. Examples of large transformations between rest energy (of matter) and other forms of energy (e.g., kinetic energy into particles with rest mass) are found in nuclear physics and particle physics . Often, however,
11970-474: The metabolism of green plants, i.e. reconverted into carbon dioxide and heat. In geology , continental drift , mountain ranges , volcanoes , and earthquakes are phenomena that can be explained in terms of energy transformations in the Earth's interior, while meteorological phenomena like wind, rain, hail , snow, lightning, tornadoes and hurricanes are all a result of energy transformations in our atmosphere brought about by solar energy . Sunlight
12103-483: The mild temperatures brought by winter Chinook winds. Central and parts of northwestern Alberta in the Peace River region are largely aspen parkland, a biome transitional between prairie to the south and boreal forest to the north. Alberta has a humid continental climate with warm summers and cold winters. The province is open to cold Arctic weather systems from the north, which often produce cold winter conditions. As
12236-427: The molecules it is built from. The second law of thermodynamics states that energy (and matter) tends to become more evenly spread out across the universe: to concentrate energy (or matter) in one specific place, it is necessary to spread out a greater amount of energy (as heat) across the remainder of the universe ("the surroundings"). Simpler organisms can achieve higher energy efficiencies than more complex ones, but
12369-447: The mountains and wooded regions. Smaller carnivores of the canine and feline families include coyotes , red foxes , Canada lynx , and bobcats . Wolverines can also be found in the northwestern areas of the province. Central and northern Alberta and the region farther north are the nesting ground of many migratory birds. Vast numbers of ducks, geese , swans and pelicans arrive in Alberta every spring and nest on or near one of
12502-473: The mountains to over 40 °C (104 °F) in southeastern Alberta. Alberta is a sunny province. Annual bright sunshine totals range between 1,900 up to just under 2,600 hours per year. Northern Alberta gets about 18 hours of daylight in the summer. The average daytime temperatures range from around 21 °C (70 °F) in the Rocky Mountain valleys and far north, up to around 28 °C (82 °F) in
12635-573: The newly formed Canadian Government purchased Rupert's Land. Northern Alberta was included in the North-Western Territory until 1870, when it and Rupert's land became Canada's North-West Territories . First Nations negotiated the Numbered Treaties with the Crown in which the Crown gained title to the land that would later become Alberta, and the Crown committed to the ongoing support of
12768-560: The north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada, with Saskatchewan being the other. The eastern part of the province is occupied by the Great Plains , while the western part borders the Rocky Mountains . The province has a predominantly continental climate but experiences quick temperature changes due to air aridity . Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds . Alberta
12901-399: The ocean. Annual precipitation ranges from 300 mm (12 in) in the southeast to 450 mm (18 in) in the north, except in the foothills of the Rocky Mountains where total precipitation including snowfall can reach 600 mm (24 in) annually. Northern Alberta is mostly covered by boreal forest and has a subarctic climate . The agricultural area of southern Alberta has
13034-453: The organization brought more than 60 of the province's business leaders to Geneva, Switzerland in an effort to showcase Alberta to the European investment community. In both 2008 and 2009 the organization brought more than 150 businessmen and politicians from across North America to tour the oil sands mining operations . Participants visited Syncrude , Albian and CNRL's Horizon Mine. In
13167-542: The parkland region of the province grow in clumps and belts on the hillsides. These are largely deciduous , typically aspen , poplar , and willow . Many species of willow and other shrubs grow in virtually any terrain. North of the North Saskatchewan River, evergreen forests prevail for thousands of square kilometres. Aspen poplar, balsam poplar ( Populus balsamifera ) or in some parts cottonwood ( Populus deltoides ), and paper birch ( Betula papyrifera ) are
13300-410: The population lives in urban areas and only about 19% in rural areas. The Calgary–Edmonton Corridor is the most urbanized area in the province and is one of the most densely populated areas of Canada. Many of Alberta's cities and towns have experienced very high rates of growth in recent history. Alberta's population rose from 73,022 in 1901 to 3,290,350 according to the 2006 census . According to
13433-427: The portion of their union dues that is spent on lobbying and political activities. The organization supported enacting a Worker Free Choice Act (WFCA) to which would allow workers the right to choose whether or not to join or financially support a union as a condition of employment. Bob Barnetson, who is an associate professor of labour relations at Athabasca University, spoke out against the study's conclusions and how it
13566-405: The primary large deciduous species. Conifers include jack pine ( Pinus banksiana ), Rocky Mountain pine, lodgepole pine ( Pinus contorta ), both white and black spruce , and the deciduous conifer tamarack ( Larix laricina ). The four climatic regions ( alpine , boreal forest , parkland , and prairie ) of Alberta are home to many different species of animals. The south and central prairie
13699-401: The province is prairie , ranging from shortgrass prairie in the southeastern corner to mixed grass prairie in an arc to the west and north of it. The central aspen parkland region extending in a broad arc between the prairies and the forests, from Calgary, north to Edmonton, and then east to Lloydminster , contains the most fertile soil in the province and most of the population. Much of
13832-574: The province is the Athabasca River , which travels 1,538 km (956 mi) from the Columbia Icefield in the Rocky Mountains to Lake Athabasca. The largest river is the Peace River with an average flow of 2,100 m /s (74,000 cu ft/s). The Peace River originates in the Rocky Mountains of northern British Columbia and flows through northern Alberta and into the Slave River,
13965-567: The province's population lives in the Calgary–Edmonton Corridor . The land grant policy to the railways served as a means to populate the province in its early years. Most of the northern half of the province is boreal forest , while the Rocky Mountains along the southwestern boundary are largely temperate coniferous forests of the Alberta Mountain forests and Alberta–British Columbia foothills forests . The southern quarter of
14098-407: The province, the bull trout , is the provincial fish and an official symbol of Alberta . Turtles are found in some water bodies in the southern part of the province. Frogs and salamanders are a few of the amphibians that make their homes in Alberta. Alberta is the only province in Canada — as well as one of the few places in the world — that is free from Norwegian rats . Since the early 1950s,
14231-605: The province. The Foremost Formation , Oldman Formation and Dinosaur Park Formations collectively comprise the Judith River Group and are the most thoroughly studied dinosaur-bearing strata in Alberta. Dinosaur-bearing strata are distributed widely throughout Alberta. The Dinosaur Provincial Park area contains outcrops of the Dinosaur Park Formation and Oldman Formation. In Alberta's central and southern regions are intermittent Scollard Formation outcrops. In
14364-592: The region, such as the first Fort Edmonton (in present-day Fort Saskatchewan). After the British arrival in Canada , approximately half of the province of Alberta, south of the Athabasca River drainage, became part of Rupert's Land which consisted of all land drained by rivers flowing into Hudson Bay . This area was granted by Charles II of England to the Hudson's Bay Company (HBC) in 1670, and rival fur trading companies were not allowed to trade in it. The Athabasca River and
14497-405: The rest mass of particles is created from the radiant energy of two (or more) annihilating photons. In general relativity, the stress–energy tensor serves as the source term for the gravitational field, in rough analogy to the way mass serves as the source term in the non-relativistic Newtonian approximation. Energy and mass are manifestations of one and the same underlying physical property of
14630-563: The rivers north of it were not in HBC territory because they drained into the Arctic Ocean instead of Hudson Bay, and they were prime habitats for fur-bearing animals. The first European explorer of the Athabasca region was Peter Pond , who learned of the Methye Portage , which allowed travel from southern rivers into the rivers north of Rupert's Land. Other North American fur traders formed
14763-474: The same total energy even in different forms) but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy . There are strict limits to how efficiently heat can be converted into work in a cyclic process, e.g. in a heat engine, as described by Carnot's theorem and the second law of thermodynamics . However, some energy transformations can be quite efficient. The direction of transformations in energy (what kind of energy
14896-523: The second ballot. After the PC leadership process, Grassroots Leadership Group members decided to keep the group together as a business advocacy organization and re-branded as Alberta Enterprise Group, headed by then-Chairman Cal Nichols . In the early days the organization was led by Tim Shipton until his departure to Join the Oilers Entertainment Group (OEG). Tim Shipton was previously director of
15029-462: The situation is the reverse. Chemical reactions are usually not possible unless the reactants surmount an energy barrier known as the activation energy . The speed of a chemical reaction (at a given temperature T ) is related to the activation energy E by the Boltzmann's population factor e ; that is, the probability of a molecule to have energy greater than or equal to E at

Alberta Connects introduced AEG members to Prime Minister Stephen Harper , Finance Minister Flaherty, Environment Minister Prentice, Liberal Leader Michael Ignatieff and 55 other Members of Parliament and Senators. In 2011, the group returned to Washington, D.C. to engage U.S political leaders in a discussion on improving trade relations between Canada and
15295-519: The sum of translational and rotational kinetic and potential energy within a system is referred to as mechanical energy , whereas nuclear energy refers to the combined potentials within an atomic nucleus from either the nuclear force or the weak force , among other examples. The word energy derives from the Ancient Greek : ἐνέργεια , romanized : energeia , lit. 'activity, operation', which possibly appears for
15428-426: The summer months between July and September. The southern and east central parts of Alberta are covered by short prairie grass, which dries up as summer lengthens, to be replaced by hardy perennials such as the prairie coneflower ( Ratibida ), fleabane , and sage ( Artemisia ). Both yellow and white sweet clover ( Melilotus ) can be found throughout the southern and central areas of the province. The trees in
15561-481: The summer, especially in central and southern Alberta. The region surrounding the Calgary–Edmonton Corridor is notable for having the highest frequency of hail in Canada, which is caused by orographic lifting from the nearby Rocky Mountains, enhancing the updraft/downdraft cycle necessary for the formation of hail. In central and northern Alberta the arrival of spring is marked by the early flowering of
15694-420: The sun . The energy industry provides the energy required for human civilization to function, which it obtains from energy resources such as fossil fuels , nuclear fuel , and renewable energy . The total energy of a system can be subdivided and classified into potential energy , kinetic energy , or combinations of the two in various ways. Kinetic energy is determined by the movement of an object – or
15827-429: The term " potential energy ". The law of conservation of energy was also first postulated in the early 19th century, and applies to any isolated system . It was argued for some years whether heat was a physical substance, dubbed the caloric , or merely a physical quantity, such as momentum . In 1845 James Prescott Joule discovered the link between mechanical work and the generation of heat. These developments led to
15960-461: The theory of conservation of energy, formalized largely by William Thomson ( Lord Kelvin ) as the field of thermodynamics . Thermodynamics aided the rapid development of explanations of chemical processes by Rudolf Clausius , Josiah Willard Gibbs , and Walther Nernst . It also led to a mathematical formulation of the concept of entropy by Clausius and to the introduction of laws of radiant energy by Jožef Stefan . According to Noether's theorem ,
16093-420: The total energy of the substances involved. Some energy may be transferred between the surroundings and the reactants in the form of heat or light; thus the products of a reaction have sometimes more but usually less energy than the reactants. A reaction is said to be exothermic or exergonic if the final state is lower on the energy scale than the initial state; in the less common case of endothermic reactions
16226-439: The two cities . English is the official language of the province. In 2016, 76.0% of Albertans were anglophone, 1.8% were francophone and 22.2% were allophone . Alberta's economy is based on hydrocarbons , petrochemical industries , livestock and agriculture. The oil and gas industry has been a pillar of Alberta's economy since 1947, when substantial oil deposits were discovered at Leduc No. 1 well. It has also become
16359-497: The unforested part of Alberta is given over either to grain farming or cattle ranching, with mixed farming more common in the north and centre, while ranching and irrigated agriculture predominate in the south. The Alberta badlands are in southeastern Alberta, where the Red Deer River crosses the flat prairie and farmland, and features deep canyons and striking landforms. Dinosaur Provincial Park , near Brooks , showcases
16492-406: The unit of measure, discovered that the gravitational potential energy lost by a descending weight attached via a string was equal to the internal energy gained by the water through friction with the paddle. In classical mechanics, energy is a conceptually and mathematically useful property, as it is a conserved quantity . Several formulations of mechanics have been developed using energy as
16625-421: The universe cooled too rapidly for hydrogen to completely fuse into heavier elements. This meant that hydrogen represents a store of potential energy that can be released by fusion. Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight. In quantum mechanics , energy
16758-401: The universe over time are characterized by various kinds of potential energy, that has been available since the Big Bang , being "released" (transformed to more active types of energy such as kinetic or radiant energy) when a triggering mechanism is available. Familiar examples of such processes include nucleosynthesis , a process ultimately using the gravitational potential energy released from
16891-489: The wooded regions, and pronghorn can be found in the prairies of southern Alberta. Bighorn sheep and mountain goats live in the Rocky Mountains. Rabbits, porcupines , skunks , squirrels, and many species of rodents and reptiles live in every corner of the province. Alberta is home to only one venomous snake species, the prairie rattlesnake . Alberta is home to many large carnivores such as wolves , grizzly bears , black bears , and mountain lions , which are found in
17024-452: Was also a territory used by fur traders of the rival companies Hudson's Bay Company and North West Company . The Dominion of Canada bought the lands that would become Alberta as part of the NWT in 1870. From the late 1800s to early 1900s, many immigrants arrived to prevent the prairies from being annexed by the United States. Growing wheat and cattle ranching also became very profitable. In 1905,
17157-732: Was conducted. However, the study was endorsed by the Merit Contractors Association, Canadian Constitution Foundation and the Canadian Federation of Independent Business. A survey conducted by AEG also found that 65 percent believed 70 percent of employees should vote to certify or decertify a union. The poll also found that 78 percent agreed that union dues should only be spent on collective bargaining and union management instead of policy influence. Im May 2011 AEG went to Washington, D.C. to talk about borders security, energy development and trade. Participants met with Members of
17290-440: Was conserved. To account for slowing due to friction, Leibniz theorized that thermal energy consisted of the motions of the constituent parts of matter, although it would be more than a century until this was generally accepted. The modern analog of this property, kinetic energy , differs from vis viva only by a factor of two. Writing in the early 18th century, Émilie du Châtelet proposed the concept of conservation of energy in
17423-569: Was named after Princess Louise Caroline Alberta (1848–1939), the fourth daughter of Queen Victoria . Princess Louise was the wife of John Campbell, Marquess of Lorne , Governor General of Canada (1878–83). Lake Louise and Mount Alberta were also named in her honour. The name "Alberta" is a feminine Latinized form of Albert , the name of Princess Louise's father, the Prince Consort ( cf. Medieval Latin : Albertus , masculine) and its Germanic cognates, ultimately derived from
17556-686: Was part of the French (and Spanish) territory of Louisiana and was sold to the United States in 1803. In the Treaty of 1818 , the portion of Louisiana north of the Forty-Ninth Parallel was ceded to Great Britain. Fur trade expanded in the north, but bloody battles occurred between the rival HBC and NWC, and in 1821 the British government forced them to merge to stop the hostilities. The amalgamated Hudson's Bay Company dominated trade in Alberta until 1870 when
17689-465: Was the homeland of the American bison , also known as buffalo, with its grasses providing pasture and breeding ground for millions of buffalo. The buffalo population was decimated during early settlement, but since then, buffalo have made a comeback, living on farms and in parks all over Alberta. Herbivores are found throughout the province. Moose , mule deer , elk , and white-tailed deer are found in
