Energy is the ability to do something (it’s do a change), and there are many pictures of energy, is the most important in the heat and light.
Within the social use: Launches the word “energy” to all those falling within the energy sources, energy production, and consumption and also save energy resources. Since all economic activities require a source of energy source, the availability and prices are among the fundamental interests and tagged. In recent years, power consumption has emerged as one of the most important Factors causing global warming and related to global warming, making it turn into a major issue in most countries of the world.
Within the context of the natural sciences, energy Yemen have to take a variety of forms: thermal energy, chemical, electrical, radiological, nuclear, and finally electromagnetic .., etc.
These species are classified as being energy kinetic energy or potential energy, with some types of energy, such as resist this category, for example: light, while the other types of energy such as heat can be a combination of 2 power potential and kinetic.
Many of these types of energy can be converted Transformation from one form to another with the help of simple tools or complicated techniques: chemical energy into electricity through common batteries or savings tool, in contrast also has Albert Einstein in the context of the theory of relativity to integrate the areas of matter and energy together so that it became possible the energy is converted into matter and vice contrary turning material into energy: This new discovery expressed Equation famous E = mc2, this transformation was translated in practice by getting energy out of nuclear fission or nuclear fusion
Terms of energy and its transformations are very useful in explaining natural processes. Even the weather phenomena such as wind and rain and lightning and tornadoes tornado is a result of the transformations of energy that comes from the sun to the earth.
Life itself is one of the results of the energy shifts: narrated photosynthesis, the sun’s energy is converted to chemical energy within plants method, are subsequently take advantage of this stored chemical energy in the metabolic processes within the living Objects .
Transformation of energy
It can convert energy from the image to another. For example, you can convert the chemical energy stored in the pocket battery to light.
The amount of energy in the world is always constant, energy is not perish not develop, but transformed from one form to another.
When it seems that energy has been exhausted, it is, in fact, may be turned into another picture, we find that this power is the ability of art to do the job (the movement) as a result of the movement or position for strong you are working on.
Energy is accompanied by the movement of so-called kinetic energy, and energy that are relevant to the position called potential energy (Effort or stored). Pendulum flip-flops by Effort energy in the final points, and in all the conditions of his final kinetic energy and energy Effort in different conditions.
Energy exists in several forms, such as energy, mechanical, thermal, thermal dynamics, chemical, electrical, radiological, and nuclear. Each of these forms of energy can be converted by the rules of appropriate ways. The food that Eat, its chemical energy stored by the body and fired when we work or do effort.
Types of energy
Animal power is the first human energy used in the dawn of civilization, when used in its pet and then proceeded to take advantage of wind power in the conduct of his boats to distant horizons. The advantage of this energy with his or her growth, and used as energy in mechanical windmills management and wheels grinding machines and wood saws and pumps lift the water from the wells and other management. This is what is known as mechanical energy.
Animals found strength derived from the chemical energy contained in the food after digestion in humans and animals. Energy and chemical found in wood that was used since ancient times in cooking and warmth. At the beginning of the Industrial Revolution were used as energy and water power operating through dynamic systems thongs and ROLLERS and gears to manage many machines.
Find thermal energy in the steam machines that the chemical energy of fuel converted to mechanical energy. God has steam-called external combustion machine, because the fuel burns abroad to generate steam, which runs the machines from the inside.
But in the 19th century invented the internal combustion machine, using fuel burning inside the machine by direct the internal combustion chambers system, to become a source of mechanical energy, which exploited in several purposes Propulsion ships, vehicles and trains.
In the 19th century the back of another source of energy, Does not need fuel combustion, the electric power generated by the dynamo (generator). These generators have become mechanical energy to electric energy that could be transported to distant places across the wire shift, making it spread, even modern energy era became especially and they multipurpose, after possible converted to light and heat, mechanical and energy, to operate machinery and electrical appliances engines. Clean energy is considered to some extent.
Then nuclear energy used in nuclear reactors emerged as being nuclear fission that generates tremendous heat generates steam that runs a generator or ships and submarines engines. But the problem lies in nuclear reactors and radioactive waste, and the possibility of radioactive leakage or explosion of the reactor occurs, as has happened in the famous Chernobyl reactor.
Non-renewable energy we get from the ground, as in a liquid oil, and as gas as natural gas, or as solid as in coal. It is non-renewable because it can not be made again or make as it again in a short time, unlike renewable energy. Renewable energy sources found in biomass derived from memberships Such as burning plants and animal bones and dung and agricultural residues beasts material energy. When you use wood or tree branches or Roth beasts in the ignition heaters or furnaces, this means we use biomass fuel that exploits as organic matter from plants and waste from agriculture or wood or animal waste. In the United States take advantage of biomass energy in the generation of 3% of the total energy has to generate 10 thousand megawatts of electric power.
And exploit geothermal energy to generate electricity and heating. Currently half of renewable energy in the United States comes from the power of the water that runs the turbine to pay, which is going the Engines to generate electricity, as is happening in Egypt in the High Dam. In America Electricity hydro power, 12% of the electricity inter represent. And can be doubled to 72 thousand megawatts.
There is also a wind power as the blades (large panels) spin-air towers over the movement of a helicopter, and fitted with an electric generators. The power of the wind advantage in windmills, water pumps, raising management, as followed in the Netherlands when the Dutch were displaced water areas of the sea to expand the agricultural area have. The cause of non-proliferation in the world sounds annoying and killing of birds colliding with the rapid Parties, and the lack of wind availability in most areas appropriately.
Also in the energy cells that are hydrogen fuel cell produces electricity through electrochemical using hydrogen and oxygen reaction.
Energy sources
Oil
Oil is a thick liquid, flammable, dark brown or greenish brown, found in the upper layer of the earth’s crust. Sometimes called naphtha, from the Persian language (“Navy” or “Nevada” which means susceptibility to the entry into force). It consists of a complex mixture of hydrocarbons, especially from the Alkane series, but differs in appearance, composition, and purity strongly from one place to another. It is a source of primary energy sources is very important (according to energy statistics in the world). Oil is the raw material for many chemical products, including fertilizers, pesticides, plastics.
Fuel
Fuel has different types of the most important fossil fuels, which includes all of the oil, coal and gas, which has been used wastefully since the last century and still uses the same wasteful with higher prices day after day, with severe damages to the environment. And others like it fuels such as oil shale, which is a mixture with sand.
Of other fuels is wooden, which covers use about 6% of the global primary energy fuel, and there is extracted from animal waste or heavy water streams of fuel, where possible to use this waste to generate power, depending upon fermentation processes, and are used in many countries around the world address heavy water to take advantage of emissions for the purpose of saving energy.
Of modern and clean in clean fuel can be a fast-growing trees plants, or some grain or vegetable oils or agricultural waste or residues of sugar cane to provide roads, some of the possible conversion of sugar to alcohol products for use as fuel for cars, as well as palm oil. This type of fuel that reduces pollution, where there is no need for the use of lead in this kind of fuel to raise the octane fuel as is the case in the gasoline of acquired him from fossil oil, and then it is lead-free petrol.
There nuclear fuel and Contains a lot of problems and the laws governing which may not devoid of double standards and injustice by allowing for use on other, in addition to the use of dangerous and bad impact on the environment.
Solar energy
Considered solar Mother energy on our planet, where emit rays all energies previously mentioned because they are going all the machines and the mechanism of the Earth heats the surrounding air, land, and generates wind and discharged, and pay water recycling cycle, Given warmth ocean, and develop the plants and feed the animals. Over time the fossil fuels in the ground. This energy can be converted directly or indirect ways to heat and cold, electricity and driving force. The sun’s rays, electromagnetic, visual spectrum rays constitute 49% of them, and the invisible ultraviolet such as the ray constitutes 2%, and infra-red 49%.
Solar vary depending on the movement and then from the ground, vary sunlight and severity of intensity over the map of the earth according to the seasons over the hemispheres and the distance from the Earth and tendencies and put it on top of geographical locations throughout the day or during the year, according to the clouds density which overshadowed, because they reduce or control the amount of radiation that reaches the land, unlike the sky free of clouds awakening or fumes. The rays of the sun fall on the walls and windows of buildings and land and water, and absorb radiation and stored in a block (article) Thermal mass. This stored heat then radiates inside buildings. This thermal mass is a solar heating system is the same function as the batteries in electric system solar (photovoltaic) voltages. Both stores the sun’s heat to be used later.
It is important to know that dark surfaces absorbed heat nor reflected much, this heat. Light color reverse surfaces that reflect the sun’s heat, so do not heat. The heat is transferred in three ways, either conduction through solids, or pregnancy-convection through gasses, liquids, or radiation. Here we find the need for heat transfer in general, the quality of the thermal material that Will be preserved in,, to save energy and costs. For this there are several principles followed by stylists for solar energy projects, including thermoelectric materials selected ability to assemble and store solar energy even in the design of buildings and construction materials selection by climatic regions, both in the tropics or in the normal or cold. As they are aware Perpendicular sun on the building and the environment around him Such as bladders of water and wind direction and the type of vegetation and soil, thermal mass, which includes ceilings, walls and water tanks. All of these considerations are important in the absorption of heat during the day and during the night leakage.
Energy seas and oceans
There clean energy sources can be used as an alternative fuel, including:
Tidal energy.
Geothermal energy.
Energy waves of the sea.
