LESSON 2 HOW CAN WE CHANGE THE ENERGY WE ARE MAKING??? RENEWABLE ENERGY SOURCES? The Oil and Water Project

IN THIS LESSON YOU WILL LEARN… WHAT DOES RENEWABLE/SUSTAINABLE ENERGY MEAN? WHAT ARE TYPES OF RENEWABLE ENERGY WHAT CAN BE USED IN TRANSPORATION WHAT ARE THE PROBLEMS?

SUSTAINABILITY… What does it mean???? Sustainable means that it can be used continuously…. The ability of something to keep on going. If a fuel is sustainable it means that it can continuously be used without running out!

WHAT DOES RENEWABLE MEANS? Renewable energy means that after we use it we can use it again. Fossil fuels are made 300 million years ago and can only be used once Renewable energy like the sun or the wind can be used again and again without worrying about it being finished eventually!

SUSTAINABLE AND RENEWABLE ENERGY SOURCES ARE SAYING THE SAME THING THEY WON’T RUN OUT AND YOU CAN CONTINUE TO USE THEM FOREVER……

WHAT ARE THE DIFFERENT KINDS OF RENEWABLE ENERGY? CLASS…LIST OFF AS MANY AS YOU KNOW!!

WATER Also called hydro- electricity Water runs down the mountains to turn big wheels that make electricity Provides about 10% of electricity in the US

SUN Also called Solar Power It dries our clothes, heats our home, creates food in the form of plants and has been used by man for 4million years! Solar panels are being used more to harness this energy and turn it into electricity and even drive cars!

WIND Has been used for centuries to grind wheat and sail our boats across the ocean Windmills are going up all over North America to make electricity NO pollution!

OCEAN Can harness energy in three ways –The Waves –The Tide –The Thermal heat Still not used very much but becoming more popular Tide energy was used 1000 years ago!

NUCLEAR ENERGY Genius work of Albert Einstein By splitting apart the middle of an atom we release A LOT of energy in the form of light and heat Fueled by URANIUM No air pollution but because it is a chain reaction produces dangerous left over “radioactive” waste

BIOMASS Everything from dead trees, crops, yard clippings, old tires and manure! Making energy from other people’s garbage. California’s garbage in a year could provide the energy to fuel 2 million homes!

GEOTHERMAL ENERGY Thousands of miles deep the center of the earth is red hot liquid MAGMA When water comes close to the magma it can sometimes be released in cracks in the earth producing ENORMOUS energy Yellowstone National Park is the biggest volcano on earth but all UNDER THE GROUND!

THE CARS WE DRIVE…. In the US….about one half of the energy we produce is for transportation! The US uses more Oil for energy than any other country on the earth!! Almost half the earth’s oil is used by the US alone This oil pollutes the air, Even the cleaner forms pollute the waterways!

WHAT IS THE STATE IN NORTH AMERICA??? GETTING WORSE!!! We are actually increasing the amount of pollutants that we make because we are continuing to driver BIGGER vehicles like minivans and SUVs! The cleaner forms of gasoline being developed are found to be using a chemical called MTBE which SPECIFICALLY poisons are rivers and lakes

HOW ELSE DOES GASOLINE AND OIL AFFECT US??? ENVIRONMENT –We are poisoning our air in the form of Greenhouse gases –We are poisoning our waterways in the form of toxins POLITICS –We depend on the Middle East and other foreign countries for oil and are vulnerable to war and unrest SOCIALLY –Oil and car companies are often corrupt drilling in the middle east and the arctic without thinking of people or environment! MONEY –We take resources from poorer countries in order to make money to keep our own energy needs funded

HOW CAN WE CHANGE OUR BEHAVIOR??? Drive less!! –take your bike, or walk or share a ride with a friend Better Cities!! –make your city build so that people can walk, have parks and get around without a car Make Cars Cleaner!!! –How can we do this??

WHAT ARE OTHER WAYS THAT WE CAN DRIVE OUR CARS??? WHAT ARE WE USING NOW? HOW CAN WE USE THE ENERGY SOURCES WE KNOW ARE RENEWABLE?

RIGHT NOW WE ARE USING OIL….A FOSSIL FUEL What do you remember about fossil fuels?? What are the problems? Where do we get them? What do they do to the air? What do they do to the water? How long to they take to re-make?

HYDROGEN FUEL CELLS Combines Hydrogen with Oxygen in the air to produce a powerful car with no pollution! Quiet to Drive. Expensive right now to make the engine?

HYBRID CARS….USING ELECTRICITY! Cars can work just like other appliances in your house and you can plug them in to power them up! Public charging stations being built Uses both electricity and gas

RIDING THE WIND! Big wind propellers at one place can be used to send energy along cables to trains and other public transport vehicles like the C-Train in Calgary, Canada

SOLAR POWERED CARS.. No exhaust Fueled only by the sun Problem: it doesn’t work at night!!! Likely not enough energy to fuel a car that a family would use Can be combined with other methods of producing energy though

BIODIESEL Oil that comes from vegetables is treated and combined with an alcohol to make biodiesel. It smells a little like french fries Provided that crops are grown sustainably this is a sustainable solution to fuel

WHICH OF THESE TYPES OF CARS DO YOU THINK ARE GOING TO WORK? Which do you think is the most expensive? Which do you think is the easiest to get? Which do you think is being used the most right now? Which do you think is the best idea for the government to start using?

THERE ARE MANY OPTIONS!! Alternative fuels for cars range from the sun, to vegetables, to electricity to the wind!!! With so many ways to fuel our cars why do we keep using oil which poisons our water and our air??? Why don’t we start using the solutions that we already know work?

THINK OF OTHER ARES OF YOUR LIFE OTHER THAN TRANSPORTATION THAT YOU COULD USE RENEWABLE ENERGY!! (example: heating your house?)

GOOD WORK!!!.....LETS WORK TOGETHER TO USE RENEWABLE ENERGY!!!! NEXT LESSON YOU WILL LEARN ABOUT THE OIL AND WATER PROJECT AND WHY THEY ARE MAKING A DIFFERENCE AND HOW YOU CAN BE INVOLVED!!
