1 Alternative Energy Save The Earth! Created By James Gillespie 2013

2 Right Now! We burn millions of tons of oil, coal and gas to power our lives. This releases incredible amounts of pollution into our air and will eventually kill our planet.

3 At The Same Time We are cutting down the forests, the trees that take CO2 out of the air, so fast it will take hundreds of years to recover.

4 The Result Temperatures are rising on the planet as more heat is trapped by CO2. This is called the greenhouse effect. The more CO2 released the hotter it will get.

5 A Hot Planet Less Ice At The PolesMore Lowland Flooding

6 What Is The Answer? There are two parts to the solution. First, stop cutting down forests and start replanting as soon as possible. Second, reduce the amount of fossil fuel we burn and find another way to drive and power our lives. We need to start using Alternative Energy Sources.

7 Alternative/Renewable Energy Solar Wind Hydroelectric Geothermal Bio-Diesel

8 It’s Free (Sort Of) Everyday the Sun pours almost limitless amounts of energy onto this planet.

9 It’s All For Us We can capture it and use in two ways. One is to turn it directly into: ELECTRICITY!!!!

10 Zero Pollution There are no moving parts and nothing to wear out. The photons of light excite the electrons and they start to flow and make: ELECTRICITY!!!!

11 Check Out This Roof That’s enough to power the whole house.

12 How Many MPG’s? A car like this could charge it’s own batteries all day while it’s parked. Otherwise it could be plugged in.

13 Want A Hot Shower? Solar energy can also be used to heat water for baths, showers and heating a home.

14 Solar Can Even Make A Power Plant These mirrors reflect sunlight to the tower full of salt and heat it to over 600˚F. This is then used to heat water into steam and drive turbines to make: ELECTRICITY!!!!

15 The World Of The Future

16 What About On A Day Like This?

17 There’s Often Wind

18 So Simple! The wind drives the blades and turns the generator to make: ELECTRICITY!!!!!

19 Even At Home A small turbine like this won’t power an entire house but it’s a start.

20 The Bluer The Windier Imagine all the wind turbines we could put in the blue areas and how much fossil fuel we would save.

21 Powered By Gravity In a hydroelectric power plant, water from the reservoir is controlled to flow through the dam to turn the turbine generator.

22 Hydroelectric Dams Gravity pulling water down can be used to drive a turbine too. This spins a generator and makes: ELECTRICITY!!!!

23 Still Simple

24 Two Hydroelectric Dams

25 Geothermal There is a lot of heat inside the Earth and we can have all we want for free!

26 Heat Absorption In Winter we can pump cold water down deep where it absorbs heat and comes up warm or hot.

27 Heat Dissipation In Summer, hot water can be pumped into the ground where the heat is absorbed and cool water comes up to cool a home.

28 It Works Both Ways These underground pipes will exchange the heat in both directions.

29 Geothermal Power Plant In some places the water is so hot it comes out as steam which can turn a turbine and make: ELECTRICITY!!!!

30 Bio-Diesel Did you know cars can run on vegetable oil?

31 From Trash To Treasure Even dirty old used up fryer oil from restaurants can be filtered and put into diesel engines.

32 Ethanol Corn can be made into ethanol that can be mixed with oils to make bio-diesel.

33 What’s The Best Part?

34 Which One Is The Solution? No single one is the best solution. Each renewable energy source is a good start and helps reduce fossil fuel burning; so what is the best solution? A comprehensive combination of all is the best solution.

35 How Much Could We Save? How much do you think we could reduce our need for fossil fuel? 25% 50% 75% 90% or more

36 What Can I Do? First, conserve energy. Turn off lights when you don’t need them, take quicker cooler showers, set your thermostats a little cooler in winter and wear a sweater and a little warmer in summer.

37 What Can I Do? Second, increase energy efficiency in your home through insulation and efficient windows, doors and appliances. Third, tell people what you know about alternative energy and, someday, put these things in your own home.

38 What Can I Do? Most important!!!! Become and educated voter! Write your Congressmen and tell them to embrace the technology that is ALREADY HERE or you and your friends and family will vote them out of office.

39 It’s Up To All Of Us!

40 So What Happens If We Do Nothing? Yesterday, an F5 tornado tore through Moore Oklahoma, destroyed homes, schools and their hospital. So far 91 have been confirmed dead including at least 20 children.

46 If We Do Nothing: Storms like this will get stronger! They will happen more often! They will happen in more places, like here! More heat and water in the atmosphere will be disastrous for everyone! Including You!
