Renewable energy sources are sources of energy that are naturally replenished at a rate equal to or faster than the rate at which they are consumed. In contrast, non-renewable sources like oil, gas and coal are being depleted faster than they can be replenished. Some key renewable energy sources include solar, wind, hydroelectric, geothermal, biomass, and ethanol. It is important to use renewable sources because they are sustainable.
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. WHAT ARE SOME TYPES OF RENEWABLE
ENERGY RESOURCES ?
• ETHANOL • HYDRO ELECTRIC
(GRAIN & CORN) POWER
• BIOMASS • SOLAR POWER
• GEOTHERMAL
• WINDPOWER ENERGY
5. SOLAR ENERGY
SOLAR 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. 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. WATER
HYDROELECTRIC
POWER USES
FLOWING
WATER , IT
CONVERTS THE
ENERGY FROM
FLOWING
WATER INTO
ELECTRICITY
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. BIOMASS
BIOMASS COMES FROM THE RENEWABLE
ORGANIC MATERIALS FROM AGRICULTURE ,
ANIMAL WAST , WOOD AND FOOD .
11. ETHANOL
ETHANOL 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. SUMMARY
WHAT ARE RENEWABLE RESOURCES
?
WHAT ARE NON RENEWABLE
RESOURCES ?
WHAT ARE SOME RENEWABLE
RESOURCES ?
WHY IS IT IMPORTANT TO USE
RENEWABLE RESOURCES ?
13. ASSIGNMENT
USING 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. SOLAR ENERGY
1. 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. WIND ENERGY
1. 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. HYDRO ENERGY
1. 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. GEOTHERMAL ENERGY
1. 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. BIOMASS
1. 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. ETHANOL
1. 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.
