Energy Energy Presentation Transcript

  • ENERGYBY: GONZALO JIMÉNEZ E ISABEL GÓMEZ
  • INDEX:-ENERGY DEFINITION-TYPES OF ENERGY-ENERGY SOURCES-RENEWABLE SOURCES-NON-RENEWABLE SOURCES-TYPES OF POWER STATIONS
  • ENERGY DEFINITIONIT IS THE CAPACITY OF A BODY FOR DOING A WORK.
  • TYPES OF ENERGY:MECHANICAL ENERGYELECTRICAL ENERGYELECTROMAGNETIC ENERGYSOUND ENERGYCHEMICAL ENERGYNUCLEAR ENERGYTHERMAL OR CALORIFIC ENERGY
  • MECHANICAL ENERGY:THERE ARE TWO TYPES OF MECHANICAL ENERGY:-KINETIC ENERGY IS ENERGY THAT OBJECTS HAVE WHEN THEY ARE INMOTION.-POTENTIAL ENERGY IS THE ENERGY THAT OBJECTS HAVE WHEN THEYARE MOVING.FOR EXAMPLE: A WINDUP CLOCK.
  • ELECTRICAL ENERGY:-THE ENERGY ASSOCIATED WITH AN ELECTRIC CURRENT.FOR EXAMPLE: A LAMP.
  • ELECTROMAGNETIC ENERGY:-TRANSPORTED BY ELECTROMAGNETIC WAVES.FOR EXAMPLE: THE RADIO.
  • SOUND ENERGY:-ASSOCIATED WITH SOUND WAVES THAT ARE TRANSMITED THROUGHVIBRATIONS.FOR EXAMPLE: THE TELEVISION.
  • CHEMICAL ENERGY:-IT IS STORED IN SUBSTANCES.FOR EXAMPLE: A CAR.
  • NUCLEAR ENERGY:-CONTAINED IN THE NUCLEI OF ATOMS.FOR EXAMPLE:THE ALUMBRATION OF A CITY.
  • THERMAL OR CALORIFIC ENERGY:-COMES FROM THE VIBRATIONS OF PARTICLES IN MATTER.FOR EXAMPLE: A RADIATOR.
  • ENERGY SOURCES ENERGY DEVELOPMENT IS THE EFFORT TO PROVIDE SUFFICIENT PRIMARY ENERGY SOURCES AND SECONDARY ENERGY FORMS FOR SUPPLY, COST, IMPACT ON AIR POLLUTION AND WATER POLLUTION, MITIGATION OF CLIMATE CHANGE WITH RENEWABLE ENERGY.
  • RENEWABLE ENERGY SOURCESRENEWABLE ENERGY COME FROM UNLIMITED NATURAL RESOURCES.THE TYPES OF RENEWABLE ENERGY ARE: HYDRAULCC ENERGY, SOLARENERGY, WIND ENERGY, MARINE ENERGY, GEOTHERMAL ENERGY,BIOMASS ENERGY AND ENERGY THAT COMES FROM MUNICIPAL SOLIDWASTE.
  • HYDRAULIC ENERGY:THIS IS IS THE MECHANICAL ENERGY PRODUCED BY THE MOVEMENT OFWATER.WE BUILD DAMS TO STORE RIVER WATER.MOST HYDRAULIC ENERGY IS USED TO PRODUCE ELECTRICITY.IT HAS ADVANTAGES LIKE: ITS CHEAP AND CLEAN, AND ITS NON-POLLUTING.ALSO IT HAS DISADVANTAGES: IT IS VERY EXPENSIVE, AND IT CAN DAMAGEFLORA AND FAUNA, AND PRODUCE A CATASTROPHE IF A DAM BREAKS.
  • SOLAR ENERGY: PRODUCTION AND TRANSFORMATION-SOLAR ENERGY IS PRODUCED BY THE THERMONUCLEAR RADIATION FROMINSIDE THE SUN. IT CAN BE USED IN VARIOUS WAYS:-TO PRODUCE HOT WATER.-TO GENERATE ELECTRICAL ENERGY USING SOLAR PANELS.-TO PRODUCE ELECTRICAL ENERGY IN HELIOSTAT FIELDS. ADVANTAGES-ITS CLEAN.-BIG POWER STATIONS ARE NOT NEEDED.-IT UNLIMITED. DISADVANTAGES-IT A VARIABLE SOURCE OF ENERGY.-SOLAR PANELS ARE STILL QUITE EXPENSIVE FOR GENERAL USE.
  • WIND ENERGY: PRODUCTION AND TRANSFORMATION-WIND ENERGY IS PRODUCED BY THE AFFECT OF VARIATION ON THEATMOSPHERE. ADVANTAGES-IT IS UNLIMITED AND NOT POLLUTING.-THE COST OF BUILDINGS AND MAINTAINING AND WIND FORM IS LOW. DISADVANTAGES-IT IS A VARIABLE SOURCE OF ENERGY.-WIND TURBINES ARE HAZARD FOR BIRDS.-WIND TURBINES PRODUCE NOISE POLLUTION.
  • OTHER RENEWABLE ENERGY SOURCES MARINE ENERGY:-TIDAL ENERGY CAN BE EXTRACTED FROM THE TIDES.-WAVE ENERGY IS OBTAINED FROM THE MOVEMENT OF SEA WATER.-OCEAN THERMAL ENERGY IS PRODUCED FROM THE DIFFERENT INTEMPERATURE BETWEEN THE SURFACE OF THE SEA AND THE DEEP SEA. GEOTHERMAL ENERGY:-THIS ENERGY COMES FROM THE HEAT STORED IN THE EARTHS CRUST. BIOMASS:-THIS IS PRODUCED FROM PLANT REMAINS, FOREST AND AGRICULTURALWASTE, HIGH-NERGY PLANTS. MUNICIPAL SOLID WASTE (MSW):-THIS IS GENERATED IN CITIES.
  • NON-RENEWABLE ENERGYNON-RENEWABLE ENERGY SOURCES COME FROM NATURAL RESOURCESTHAT ARE UNLIMITED.THE MAIN RESOURCES OF ENERGY ARE:NUCLEAR ENERGY, COAL, PETROLEUM AND NATURAL GAS.
  • NUCLEAR ENERGYNUCLEAR ENERGY IS STORED IN NUCLEI OF ATOMS THIS IS RELEASED INTHE NUCLEAR REACTION THAT OCCURS IN CERTAIN ATOMS.THERE ARE TWO TYPES OF NUCLEAR ENERGY:-NUCLEAR FISSION. THIS IS WHEN THE NUCLEUS IS SPLIT BYBOMBARDING.-NUCLEAR FUSION.THIS IS WHEN TWO NUCLEIJOIN TO FORM ANOTHER.
  • COALTHE REMAIN OF PLANTS THAT WERE BURIED AND TRANSFORMED IN THEABSENCE OF OXYGEN.THERE ARE TWO METHODS FOR EXTRACTING COAL:-OPEN-CAST MINES. WHEN THE COAL IS CLOSED TO THE SURFACE.-UNDERGROUND MINES. WHEN THE MINERAL IS BURIED DEEP BELOW THESURFACE.
  • PETROLEUMPETROLEUM IS FORMED FROM THE BURIED REMAINS OF PLANTS ANDANIMALS THAT HAVE DECOMPOSED BECAUSE OF BACTERIAL ACTION. ITIS A LIQUID SUBSTANCE.WE CAN USE TO THINGS FOR TRANSPORTING:-OIL TANKERS. IT IS A SPECIALISED SHIP DESIGNED FORINTERCONTINENTAL TRANSPORT.-OIL PIPELINES.IT IS A ENORMOUS STEEL PIPE.
  • NATURAL GASNATURAL GASES IS A MIXTURE OF GASES FORMED FROM DECOMPOSEDPLANTS AND ANIMAL. IT IS FOUND IN UNDERGROUND GAS FIELDS AND INPOROUS ROCKS.IT IS VERY EXPENSIVE TO EXTRACT.NATURAL GAS IS TRANSPORTED FROM GAS FIELDS BY GAS PIPELINES TO ALIQUEFACTION PLANT.
  • HYDRAULIC POWER STATIONSDAMS BUILT TO PRODUCE HYDROELECTRICITY IMPOUND A RESERVOIR OFWATER AND RELEASE IT THROUGH ONE OR MORE WATER TURBINES,CONNECTED TO GENERATORS, AND GENERATE ELECTRICITY, FROM THEENERGY PROVIDED BY DIFFERENCE IN WATER LEVEL UPSTREAM ANDDOWNSTREAM.
  • SOLAR POWER STATIONSSOLAR ENERGY CAN BE TURNED INTO ELECTRICITY EITHER DIRECTLY INSOLAR CELLS, OR IN A CONCENTRATING SOLAR POWER PLANT BY FOCUSINGTHE LIGHT TO RUN A HEAT ENGINE.A SOLAR PHOTOVOLTAIC POWER PLANTCONVERTS SUNLIGHT INTO DIRECT CURRENT ELECTRICITY USING THEPHOTOELECTRIC EFFECT.
  • THERMAL POWER STATIONSIN THERMAL POWER STATIONS, MECHANICAL POWER IS PRODUCED BY A HEATENGINE THAT TRANSFORMS THERMAL ENERGY, OFTEN FROM COMBUSTION OFA FUEL, INTO ROTATIONAL ENERGY. MOST THERMAL POWER STATIONSPRODUCE STEAM, AND THESE ARE SOMETIMES CALLED STEAM POWERSTATIONS. NOT ALL THERMAL ENERGY CAN BE TRANSFORMED INTOMECHANICAL POWER, ACCORDING TO THE SECOND LAW OF THERMODYNAMICS.
  • NUCLEAR POWER STATIONSA NUCLEAR POWER PLANT IS A THERMAL POWER STATION IN WHICH THEHEAT SOURCE IS ONE OR MORE NUCLEAR REACTORS. AS IN ACONVENTIONAL THERMAL POWER STATION THE HEAT IS USED TO GENERATESTEAM WHICH DRIVES A STEAM TURBINE CONNECTED TO A GENERATORWHICH PRODUCES ELECTRICITY. AS OF FEBRUARY 2ND, 2012, THERE WERE439 NUCLEAR POWER PLANTS IN OPERATION THROUGH THE WORLD.
  • WIND POWER STATIONSWIND TURBINES CAN BE USED TO GENERATE ELECTRICITY IN AREAS WITHSTRONG, STEADY WINDS, SOMETIMES OFFSHORE. MANY DIFFERENTDESIGNS HAVE BEEN USED IN THE PAST, BUT ALMOST ALL MODERNTURBINES BEING PRODUCED TODAY USE A THREE-BLADED, UPWIND DESIGN.GRID-CONNECTED WIND TURBINES NOW BEING BUILT ARE MUCH LARGERTHAN THE UNITS INSTALLED DURING THE 1970S, AND SO PRODUCE POWERMORE CHEAPLY AND RELIABLY THAN EARLIER MODELS.
  • WIND TURBINE CREATES WATER FROM THIN AIRTHE TURBINE CAN PRODUCE UP TO 1,000 LITERS OF DRINKING WATER EVERYDAY, ACCORDING TO EOLE WATER. FRENCH COMPANY, EOLE WATER, HASINVENTED A WIND TURBINE THAT CAN GENERATE WATER FROM HUMID AIR. THETECHNOLOGY OFFERS A CLEAN AND SUSTAINABLE WAY TO PROVIDE WATER TORURAL COMMUNITIES, SAYS EOLE WATER DIRECTOR OF MARKETING, THIBAULTJANIN. A VIEW INSIDE THE TECHNOLOGICAL PROCESSES OF THE EOLE WATERTURBINE. THE 24-METER TALL STRUCTURE ALSO FILTERS AND PURIFIES THEWATER IT PRODUCES ENSURING IT IS SUITABLE TO DRINK STRAIGHT AWAY.
