3 What is it electrical energy What is it electrical energy? Electrical energy - it kind of energy, which can readily be converted to other types of energy using appliances. Energy electrical current : E=UIt U - tension electrical current I - intensity electrical current t - flow time electrical current E- energy electrical current

4 Electrical energy from the Earth Electrical energy can be caused by processing of nuclear energy (nuclear).

5 Nuclear energy Nuclear energy – part of the binding energy of atomic nuclei in the process of liberating the fission of heavy nuclei and the merger (fusion) of light nuclei. Formula for energy : E=mc 2

6 Nuclear power station Nuclear power station– the object of industry and energy (heat and power plant), producing electricity by using energy from fission of nuclei of atoms, mostly of uranium (natural uranium or slightly enriched in the isotope U-235), in which heat is necessary to obtain the pair, is obtained from nuclear reactor.

7 Construction of nuclear power station The general principle of a nuclear power plant (for example, circulation PWR): In a nuclear reactor by the reaction of fission of atomic nuclei emit large amounts of heat that is picked up by a working medium (usually water under high pressure in the so-called primary circuit - PWR and WWER reactors). Factor flows to the steam generator, which supplies heat to the boiling water re-circulation of a lower pressure, and then returns to reactor. Water vapor (steam wet, which is dried before reaching the turbine - the water molecules in a pair of wet, high pressure turbine have destroyed, so first couple passes wet from the steam generator systems drying before it reaches the turbine) then drives the steam turbine combined generator. Separation of circuits is more secure in case of leakage from the steam turbine.

24 For the solar radiation reaching the Earth spectrally similar to the blackbody radiation at a temperature of about 5700 K. Before entering into the atmosphere radiation power is equal to 1367 W / m² perpendicular to solar radiation. Part of this energy is reflected and absorbed by the atmosphere, the Earth's surface on a sunny day it reaches about 1000 W / m². Solar radiation

33 Electrical energy from air Electrical energy from air we can generate using wind energy Wind energy is one of the renewable energy sources. Currently used wind turbines convert it into mechanical energy, which further is converted to electricity. Wind energy is dependent on its velocity v in the third power and thus locations for wind energy are selected carefully for the incidence of severe (7-20 m / s) winds.

34 Wind energy, we obtain with Windmills Wind motors

35 Windmills Windmill - oldest wind motors. Wind energy converts into kinetic energy of rotation. Windmill in Lednogórze at route Poznan - Gniezno

36 The entire mill was built of wood, and mostly covered with shingles outside. Windmill Kozłowy had three floors - the bottom was occupied by stabilizing the structure goat, and two were higher for the production of flour. Shingled walls initially did not extend nearly to the ground and visible from afar revealed the buck. Schematic diagram of the internal fan

37 Wind motors They are designed to process the kinetic energy of wind to mechanical energy, which is then used to generate electricity. Wind motors Vertical axis turbines Horizontal axis turbines

38 The wind turbine is equipped with such in: impeller (rotor), which translates the energy of wind energy into mechanical energy. generator - using the supplied mechanical energy to generate electricity and transmit it to the network. Wind motors Low-speed They are characterized by a high torque to boot and blades from 12 to 40 Middle-speed have blades 4-7 Speed have less starting torque of the motor coaster, are equipped with 1-3 blades. Can achieve high aerodynamic efficiency.

39 Wind motor diagram Here form the rotor blades, the hub through which are embedded in the shaft. Shaft turns in bearings contained in a casing, which houses a gear drive for transferring the vertical shaft. This shaft drives the machine working normally generator, is often placed at the bottom. Together with the shaft and the rotor is mounted directional rudder. It provides a setting to the engine, "the wind", so that the rotor plane is perpendicular to the wind speed through the revolving rotor and casing clamping against the tower.

47 Friendly: renewable energy sources Less friendly: coal combustion petroleum nuclear energy (already mentioned) burning of fossil fuels

48 Renewable energy sources are energy sources, whose use is not associated with their long-term deficit - the resource renews in a short time. The most important renewable energy is a drop of water. Other renewable sources include: solar power (mentioned earlier), wind energy (already mentioned) biomass, biomass biogas, biogas geothermal energy, geothermal energy hydropower. hydropower Renewable energy should not be confused with energy environmentally friendly because its production facilities may (but need not) cause environmental damage.

49 Biomass - mass of matter contained in the organisms. Biomass is given in relation to the surface (per square meter or kilometer) or volume (eg in the aquatic environment - per cubic meter). Biomass is expressed in terms of fresh weight (living organisms or natural mass of living organisms) and dry mass (weight of living organisms after drying or evaporation of water). Biomass is expressed in units of weight (eg gram or kilogram) and also in terms of organic carbon, or in units of energy (calorie, joule). Measurement of biomass can calculate the biological production (see productivity) of the individual units of biological organization: individual, population, biocenosis ecosystem, biom or the entire biosphere.

50 Through photosynthesis solar energy is accumulated in the biomass, plant organisms initially, and later in the food chain and animal. Energy contained in the biomass can be used for human purposes. This involves the processing of other forms of energy by biomass burning or incineration of its degradation products. As a result of heat of combustion is obtained, which can be processed into other forms of energy such as electricity. For the purposes of energy is used most often : timber of low technological quality and waste animal faeces sludge straw, oil cake and other wastes of agricultural production seaweed grown specifically for energy purposes organic waste such as beet pulp, corn stalks, grass, alfalfa vegetable oils and animal fats.

51 Biomass energy is achieved inter alia through : gasification - producer gas (mainly hydrogen and carbon monoxide) resulting from gasification of biomass in closed reactors (so-called gazogeneratorach) - it is burned in a boiler or directly drives a gas turbine or internal combustion engine can also be a raw material for Fischer-Tropsch synthesis. by fermentation of biomass derived biogas, methanol, ethanol, butanol and other compounds that can be used as fuel. esterification – biodiesel.

52 Biogas, landfill gas - a combustible gas, the product of anaerobic fermentation of organic compounds (eg sewage, including waste water, sugar, municipal waste, manure, slurry, waste, agri-food industry, biomass) and partly also to their decay resulting in a biogas plant. As a result of combustion of biogas formed contrary beliefs as much nitrogen oxides, which in case of combustion of fossil fuels.

53 The crude biogas consists of approximately 65% (between 50-75%) of methane and 35% of carbon dioxide and other greenhouse gas admixture (such as hydrogen sulphide, carbon monoxide), its calorific value ranges from 1917 to 1927 MJ / m3 (megajoules per cubic meter of biogas, in normal conditions, ie 0 ° C and 105 Pa), depending mainly on the content of methane. Composition of biogas Component % methane, CH carbon dioxide, CO nitrogen, N 2 0-0,3 hydrogen, H hydrogen sulphide, H 2 S 0-3 oxygen, O 2 0,1-0,5

54 BIOGAS PRODUCTION METHODS At the landfill biogas is produced automatically, hence the name of landfill gas. Biogas also arises naturally eg peat bogs (mainly cellulose), we call it when gas or gas rotting mud.

55 Biogas is widely used: it is used mainly in India, China, Switzerland, France, Germany and the United States as fuel for electric generators (with 100m ³ of biogas can produce approximately kWh of electricity), as an energy source for heating water, and after purification and compression as fuel for the propulsion engines (CNG).

Until 2013, Poland plans to produce a biogas including mld3 for heating buildings. According to Ministry of Agriculture to implement these measures will improve energy security and the environment.

56 Geothermal energy - a type of renewable energy sources. It is based on the use of thermal energy of the interior, particularly in the areas of volcanic and seismic activity. Runoff water infiltrates into the ground, where in contact with the young or active outbreaks intruzjami magma, heats up to substantial temperatures. As a result of that goes to the earth's surface as hot water or steam. Geothermal energy - a type of renewable energy sources.

62 The kinetic energy of sea currents Tidal power Energy wave

63 The power of sea currents is estimated at 7 TW (it is almost two times more than the power possible to receive from the estate of inland waters). However, its use is close to zero due to technical problems and concerns before the disturbance of natural balance. Many researchers believe that ocean currents are fundamental to the climate and the depletion of their energy, though small, could lead to unpredictable climate change.

64 Tides are the source of lower potential energy (it is estimated that it is possible to use the 200 GW) than ocean currents, but it is safer and better they met. The first tidal power plant built in 1967, the French in Saint-Malo. This station has a maximum power of 550 MW and operates from 4 to 8 hours a day, producing an average of 600 GWh of electricity annually. Currently, such plants are also in Russia and Britain, but none of them currently (January 2007) does not work on an industrial scale due to technical problems and the danger of storms and hurricanes.

65 Wave power is estimated at 3 TW, but the use of this energy causes some difficulties, although many of the theoretical methods for converting wave energy into electricity. The biggest problem is the variability of wave height and strength of the plant.

66 The most important ways of converting wave energy into electrical pneumatic power – waves stimulate movement of air in them, which drives a turbine mechanical power plants - which use buoyancy to move perpendicular to the floor, causing the rotation of the rotor connected to the generator inductive power plants - use the movement of floats to generate electricity by using moving coils with floats in a magnetic field hydraulic power - in which the immovable wall of the tank overflow, only the peaks of the waves, and the water flowing from the tank drives a turbine

67 Coal burning is the most common way of obtaining energy. This is the cheapest way, but the most to contribute to environmental pollution. Its combustion leads to excessive pollution, contamination of the ecosystem, including groundwater and soil itself. Mere coal burning causes carbon dioxide emissions into the atmosphere, which in turn leads to the so-called. greenhouse effect, which leads to severe climate change on our planet. Another harmful effect, is also a way of extracting coal that is mined by people. His exploration leads to the creation of these various diseases, of which pneumoconiosis is the most dangerous.

68 At its base are created all the liquid fuel to propel various types of internal combustion engines. But this is a very dangerous material to the environment. Often there are sad disaster, the transportation of natural gas. These disasters lead to contamination of the environment and often to the death of many animals. Its operation is carried out on a large scale, which is forced a huge global demand. But this will not drag on forever. Crude oil man out only a hundred years, and already it is estimated that for about 30 years, it may completely fail.

69 Burning fossil fuels has a major impact on our environment, adverse effects. It is impossible not to draw attention to such a great problem which are products of fuel combustion, because it concerns us all. For these products include: gas containing fly ash (dust), sulfur dioxide, nitrogen oxides, carbon monoxide and dioxide, slag from the boilers, waste and waste water from flue gas desulphurization system. During the process of combustion of fossil fuels also comes the release of such elements as whether the circuit boards. In addition, coal is used in Poland is considered to be particularly burdensome to the fuel environment. Burning fossil fuels has a major impact on our environment, adverse effects.

70 Air pollution affects human health, wildlife alive, climate, water and soil. The degree of harmfulness of pollutants determines their nature, concentration and dwell time. Gaseous and particulate air pollution increases the incidence of respiratory diseases and forest dieback, and substantial economic losses. In addition to the burning of fossil fuels causes global warming and pollution by sulfur compounds, nitrogen and dust. Air pollution affects human health, wildlife alive, climate, water and soil.

71 Example electrical energy of the elements in Tarnobrzeg Solar collectors

72 The solar collectors are installed elements that mediate the conversion of solar energy in heat. Intermediary factor in the exchange of heat may be air or liquid, which involves the distribution of collectors on the air (rarely used because of the low efficiency of heat exchange) and the liquid.

73 Breakdown of solar collectors Breakdown of liquid collectors due to construction flat - they have the simplest structure - consists of an absorber of sunlight and connected to the copper tube through which fluid receives heat from the absorber, the whole is enclosed in an insulated housing vacuum - may be to direct the flow of working medium or with heat pipes

74 The principle of working solar collector Measure the collector is as follows: The sun heats the collector placed in the absorber, which absorbs sunlight and converts it into heat. The effectiveness of absorption depends on the absorber. Plain, black absorber large part of the radiation is reflected. Better is called. selective absorber - it absorbs 95% of the radiation incident on it. Since the absorber is heated heating agent (which may be liquid water or freeze), which flows through the collector. Heated fluid flows into the tray. There it gives off the heat heated water utility, located in the tray, and cooled back to affect the drain.
