• Examples of non renewable energysources: coal, fossil fuels, etc…

• They will run out eventually

• Bad for the environment• Negative health effects

Power?

ower?

• renewable energy source

•The conversion of solarpower from the sun into

heat or electricity•!ses solar panels

•There are three mainmethods of obtaining solar

power•Best suited for areaswhere there is low cloudcover that will bloc" out thesunlight

Energy

nergy

Photovoltaic cells•#onsists of semi$conductors

•s light hits the surface, energy is produced

Solar Thermal Electricity

• mirror is used to reflect the sunlight to a

central receiver

• fluid is circulated that drives a generator

•The generator produces electricity

Solar Thermal Heater

•%olar panels on roof absorbs sunlight

•%unlight is converted into energy that heats

the house

solar energy can beused in remote areaswhere no other energysource is available

•&e)uire very littlemaintenance

•lthough expensive inthe beginning, you willsave a lot money in thelong$term

•#an be unreliable unless you+re in avery sunny climate- .or example, itwouldn/t be very effective in the !nited0ingdom

• %olar power isn+t much use for high$power applications- (t may 1ust be

enough to heat your house- To obtaindecent amounts of solar power, youneed a large area of solar panels-

The Effects of olar Power

he Effects of olar Power

on the& & &n the& & &

• Atmosphere: No release of pollutants • Lithosphere: No effect because solar

panels are usually 1ust installed on pre$existing buildings

• Hydrosphere: No effect

• Biosphere: 2ight is reflected off thepanels- This light can distract birds andeven airplane pilots- This can bedangerous-

rgentina

•%olar power is being usedto improve the lives ofvillagers in a smallcommunity in rgentina

•The Econdina.oundation introducedsolar powered stoves tothe villagers so that theycould coo" food easily

•Before the solar powercoo"ing stoves were

available, the villagers hadto use fire wood

•%ince rgentina receivesa good amount of sun, itdefinitely comes in handy

•The goal of the plan is to

have 34 gigawatts ofsolar energy by the year3433-

•The entire pro1ect is

estimated to cost about534 billion-

What is Wind Power?

hat is Wind Power?

•(t is a renewable energysource

•The use of the wind toproduce electricity

•ind energy is the fastestgrowing energy source onearth

•The rate at which technology

is improving is ma"ing windpower more and moreappealing

• The wind is free

• *oes not cause green house gases or otherpollutants-

•lthough wind turbines can be very tall, they onlyta"e up a small plot of land- Therefore, the landbelow can still be used

•The amount of wind available alwaysvaries- There will be times when theyproduce no electricity at all-

•ind turbines can be noisy- (t can bee)uivalent to the noise of a car

traveling at >4 mph-•Because wind turbines have to beanchored to the ground this couldpossibly impact soil structure-

•They do not produce enoughelectricity to power large amounts ofhomes-

•Birds and bats are threatenedbecause they can get caught in the

turbines-

Conclusion

onclusion

•(nvesting in renewable energy sources such as wind and solar power is very

important•%olar and wind power provide clean energy

•Both methods come with advantages and disadvantages

•opefully, with rapidly growing technology, these two power sources will

become used all over the world and replace non renewable sources
