2. WHAT IS RENEWABLE ENERGY?
• Renewable energy is energy
produced from sources like the
sun and wind that are naturally
replenished and do not run out.
Renewable energy can be used
for electricity generation, space
and water heating and cooling,
and transportation.

3. BENEFITS OF RENEWABLE ENERGY
• MATERIALS:
Renewableenergyuse lessand inexpensive
materialsthanother forms ofenergy.For instance,
solarpanels arenow affordablebecause theyare
madeofless expensivematerials.In addition,the
materialsare affordable,safe,and effectivein
providing energytoour homes andoffices.

4. • ENERGY SAVINGS:
One ofthemainreasons why wehave renewable
energyis tosave onenergy.With non-renewable
energy,a lot ofenergy isused.Happily,renewable
energyhas managedtosafeguardenergyuse and
helptosavetheenvironment andmoney as well.
According torecent findings,peoplesavemore than
30 percentoftheir energycosts by using renewable
energy.

5. • SAVES MONEY:
Apart from saving energy, renewable energy
helps you to save money inthe future.It is
believedthatnuclear energyand fuelenergywill
rise in cost in thefuture.However, studies show
thatrenewable energy cost will keep decreasing
since thereare many innovations being done all
over the world.

6. TYPES OF RENEWABLE ENERGY
• SOLAR ENERGY
• WIND ENERGY
• GEOTHERMAL ENERGY
• TIDAL ENERGY

7. SOLAR ENERGY

8. SOLAR ENERGY
We usesolar thermalenergy systemsto
• heatwaterfor use in homes,buildings,or swimmingpools
• heattheinside ofhomes,greenhouses,andother buildings
• heatfluidsto high temperaturesin solar thermalpower plants
Solar photovoltaic devices, or solar cells, change sunlight
directly into electricity.

9. SOLAR ENERGY
The twomain benefits of using solar energy are
• Systems do not produce air pollutants or carbon dioxide.
• Systems on buildings have minimal impact on the environment.
The main limitations of solar energy are
• The amountof sunlight that arrives at the earth's surface is not constant. The amount of
sunlight varies depending on location, time of day, season of the year, and weather
conditions.
• The amountof sunlight reaching a square foot of the earth's surface is relatively small, so a
large surface area is necessary to absorb or collect a useful amount of energy.

10. WIND ENERGY

11. WIND ENERGY
• Wind turbines operate on a simple principle. Theenergyin the wind turns two or
three propeller-like blades around a rotor. The rotoris connected to the main shaft,
which spins a generator to createelectricity.

12. WIND ENERGY
• Wind turbines are mounted on a tower to capture the most energy. At
100 feet or more above ground, they can takeadvantage of faster and
less turbulent wind.
• Wind turbines can be used to produce electricity for a single home or
building, or they can be connected to anelectricity grid for more
widespread electricity distribution.

13. WIND ENERGY
• Advantages of Wind Energy
– Clean and renewable source of power
– Cost effective
– Rapid growth of industry, large potential
• Disadvantages of Wind Energy
– Wind reliability
– Threat to wildlife
– Noise and visual pollution

14. TIDAL ENERGY
• Tidal Stream Generator
– Makes useof the kineticenergy of moving water to power turbines, in a similar way to wind
turbines that use wind to power turbines.
• Tidal Barrage
– Tidal barrages makeuse of the potential energyinthe difference inheight between high and low tides.

15. TIDAL ENERGY
• Advantages
– Clean fuel sourcecomparedtofossil fuels
– Domesticsourceofenergy
• Disadvantages
– Tidalpowercanhaveeffects onmarinelife.
• Theturbinescanaccidentallykill swimming sea lifewiththe rotatingblades.
• Somefishmaynolonger utilizethe areaif threatenedwith aconstantrotatingornoise-

16. GEOTHERMAL ENERGY
• (geo = earth and thermal= heat),geothermalenergy comes
from heatproduced by the Earth.

17. GEOTHERMAL ENERGY
• Direct geothermal energycan be accessed in areaswhere hot
springs/geothermal reservoirs are near the surface of the Earth.
• Geothermal heat pumpsutilizes a series of underground pipes, an
electric compressor and a heat exchanger to absorb and transfer heat.
• Geothermal powerplantsalso harness the heat of the Earththrough
hot water and steam. In these plants, heat is used to generate
electricity.

18. GEOTHERMAL ENERGY
• Advantages
– Renewableenergy
– Cleanerthanburningfossil fuels
• Disadvantages
– Costofdrilling, researchingproperareas
– Requiresasuitablelocation
• 1-Hot water extracted from earth
• 2-Hot water converts to steam
• 3-Steam goes through a turbine generator
• 4-In the cooling tower, steams cools down
• 5-The condensed water is returned to earth
