Renewable energy sources

  1. 1. RENEWABLEENERGY SOURCES Ms Totten
  2. 2. AIMWhat are Renewable Energy Sources an Why are they important ?
  3. 3. Renewable Energy Sources RENEABLE RESOURCES SOURCES OF ENERGY THAT ARE NATURALLY SOUCES THAT REPLENISH AT A RATE EQUAL TO OR EVEN FASTER THAN THE RATE THAT THEY ARE USED. NON RENEWABLE ENERGY SOURCES INCLUDING OIL, GAS AND COAL ARE BEING USED FAR BEYOND THE RATE OF REGENERATION.
  4. 4. WHAT ARE SOME TYPES OF RENEWABLEENERGY RESOURCES ?• ETHANOL • HYDRO ELECTRIC(GRAIN & CORN) POWER• BIOMASS • SOLAR POWER • GEOTHERMAL• WINDPOWER ENERGY
  5. 5. SOLAR ENERGYSOLAR ENERGY IS THE CONVERSION OF SOLAR HEAT INTO ELECTRICITY . SOLAR ENERGY IS USED TO CONVERT SUNLIGHT INTO ELECTRICITY AND IT USES THE HEAT FROM THE SUN TO PROVIDE HEATING SYSTEMS
  6. 6. WIND WIND ENERGY IS ENERGY THAT IS DIRIVED FROM THE NATURAL WIND FOUND ON EARTH. THE ENERGY FROM THE WIND IS HARVESTED THEN CONVERTED INTO ELECTRICITY.
  7. 7. WATER HYDROELECTRIC POWER USES FLOWING WATER , IT CONVERTS THE ENERGY FROM FLOWING WATER INTO ELECTRICITY
  8. 8. GEOTHERMAL ENERGY GEOTHERMAL ENERGY IS ENERGY THAT COMES FROM THE EART. HOT WATER AND STEAM IS CREATED WHEN UNDERGROUND WATER COMES IN CONTACT WITH THE HOT LAYERS OF THE EATH AND IT SURFACES TO THE TOP THROUGH A SPRING.
  9. 9. BIOMASSBIOMASS COMES FROM THE RENEWABLE ORGANIC MATERIALS FROM AGRICULTURE , ANIMAL WAST , WOOD AND FOOD .
  10. 10. BIOMASS
  11. 11. ETHANOLETHANOL IS ETHYL ALCOHOL THAN CAN BE USED FOR FEUL. ETHANOL IS DIRIVED FROM CROPS AND PLANTS THAT CONTAIN SUGAR, THIS IS THEN CONVERTED INTO ETHANOL AND IS USED AS FEUL.
  12. 12. SUMMARY WHAT ARE RENEWABLE RESOURCES ? WHAT ARE NON RENEWABLE RESOURCES ? WHAT ARE SOME RENEWABLE RESOURCES ? WHY IS IT IMPORTANT TO USE RENEWABLE RESOURCES ?
  13. 13. ASSIGNMENTUSING THE RENEWABLE RESOURCE THAT IS ASSIGNED TO YOU ANSWER THE FOLLOWING QUESTIONS:1. HOW IS THIS RESOURCE CONVERTED INTO ELECTRICITY ?2. WHAT ARE THE ADVANTAGES/ DISADVANTAGES OF THE RESOURCE ?3. WHY IS THIS RESOURCE CONSIDERED AN RENEWABLE RESOURCE ?
  14. 14. SOLAR ENERGY1. SOLAR ENERGY IS CONVERTED INTO ELECTRICITY USING PV CELLS THAT TRANSFER THE SOLAR ENERGY INTO ELECRICITY .2. THE ADVANTAGES ARE THAT IT IS AN UNLIMITED RESOURCES , THE SOLAR ENERGY HAS NO NEGITVE ENVIRONMENTAL IMPACTS , THEY ARE GENREALLY MAINTANCE FREE. THE DISADVANTAGES ARE THAT THE INITIAL COST MAY BE EXPENSIVE TO SOME , HOWEVER THERE ARE FINICAIL INCENTIVES FROM THE GOVERNMENT AND AN OPPORTUNITY TO GAIN PROFIT.3. SOLAR ENERGY IS CONSIDERED AN RENEWABLE RESOURCE BECAUSE THE RATE AT WHICH WE CAN CONSUME IT DOES NOT EXCEED THE RATE OF WHICH IT IS CREATED
  15. 15. WIND ENERGY1. WIND ENERGY USES WIND TURBINES TO HARNESS THE ENEGRY FROM THE WIND , THESE TURBINES ARE CONNECTED TO GENERATORS THAT CONVER THE WIND INTO ELECTRICITY .2. THE ADVANTAGES OF WIND POWER IS THAT IT IS UNLIMITLESS . THE ADVATAGES ARE THE WIND IS NOT CONSISTANT , THE INSTALLATION OF WIND TURBINES CAN ALTER WEATHER PATTERNS , THE INSTALLATION OF WIND TURBINES DECREASE PROPERTY VALUES.3. WIND ENERGY IS CONSIDERED AN RENEWABLE RESOURCE BECAUSE THE RATE AT WHICH WE CAN CONSUME IT DOES NOT EXCEED THE RATE OF WHICH IT IS CREATED. AS LONG AS THERE IS WIND IT CAN BE USED.
  16. 16. HYDRO ENERGY1. WATER ENERGY (HYDROELECTRICITY) CREATES ELECTRICITY BY ALLOWING THE ENERGY FROM FLOWING WATER TO BE CONVERTED TO ELECTRICITY BY USING GENERATOR.2. THE ADVATAGES ARE THAT IT HAS LITTLE TO NO NEGATIVE IMPACTS ON THE ENVIROMENT, IT IS A RENEWABLE RESOURCE. THE DISADVANGES ARE THE INCONSISTANCY OF FLOWING WATER , IN ODER TO USE IN STANDING WATER FUEL POWERED MILLS MOVE THE WATER.3. HYDRO ELECTRICITY IS CONSIDERED A RENEWABLE SOURCE BECAUSE AS LONG AS WE HAVE WATER IT CAN BE USED FOR POWER. ALSO WE ARE NOT ACTUALLY CONSUMING THE WATER WE ARE JUST HARNESSING ITS MOVEMENT.
  17. 17. GEOTHERMAL ENERGY1. GEOTHERMAL ENERGY USES PUMPS TO HARNESS THE ENERGY FROM STEAM THAT IS NATURALLY FOUND UNDER THE SURFACE OF THE EARTH THE HEAT IS THEN TUNNELED INTO AN HEAT CONVERTED WHERE THE ENERGY IS TRANSFERRED INTO ELECTRICITY.2. THE ADVANTAGES OF GEOTHERMAL ENERGY IS THAT IT IS LIMITLESS , THE DISADVANTAGES ARE WE DO NOT KNOW HOW CONSISTANT IT IS , AND WE DO NOT YET KNOW IF THERE IS NEGATIVE IMPACTS ON THE ENVIRONMENT FROM DIGGING INTO THE EARTH.3. THIS IS A RENEWABLE RESOURCE BECAUSE WE ARE NOT ACTUALLY CONSUMING THE STEAM , WE ARE JUST TRANSFERING THE STEAM INTO USUABLE ENERGY.
  18. 18. BIOMASS1. BIOMASS USES ORGANIC MATERIAL . THE BIOMASS PROCESS ALLOWS FOR THE ORGANIC MATERAL TO DECOMPOSE AND FERMENT THEN HARVEST THE GASES FROM THE FERMENTATION.2. THE ADVANTAGES INCLUDE NO NEGATIVE IMPACT ON THE ENVIORNMENT , IT REDUCES THE AMOUNT OF WASTE, RECYLES , AND REDUCES OUR DEPENDANCY ON NON RENEWABLE RESOURCES.3. BIOMASS IS A RENEWABLE RESOURCE BECAUSE WE DO NOT CONSUME IT MORE THAN IT IS CREATED . EVERYDAY WE CREATE WASTE AND THAT WASTE CAN BE CONVERTED INTO ENERGY.
  19. 19. ETHANOL1. ENTHANOL IS CREATED BY USING GRAIN OR VEGETABLE CROPS THAT CONTAIN SUGAR. THESE CROPS ARE THEN FERMENTED TO HARNESS THE ENTHANOL FROM IT IN ORDER TO BE USED AS FUEL.2. THE ADVANTAGES OF ETHANOL IS THAT IT IS A RENEWABLE RESOURCE , IT WILL REDUCE OUR DEPENDANCY ON NATURAL OIL AND THAT IT IS EASY TO CREATE, AND IT IS ENERGY POSITIVE. THE DISADVANTAGES INCLUDE IT STILL CAUSE POLLUTION , AND WE STILL NEED OIL TO CREATE IT .3. ETHANOL IS CONSIDERED A RENEWABLE RESOURCES BECAUSE THE CROPS CAN BE GROWN QUICKLY AND IN LARGE PORTIONS. THE RATE AT WHICH WE CREATE ETHANOL FROM THE CROPS DOES NOT EXCEED THE AMOUNT WE USE. THE CROPS CAN BE REPLENISHED.
