  1. 3.1 NONRENEWABLE ANDRENEWABLERESOURCES

  2. HMMMM.... What do you think nonrenewable resources are?

  3. NONRENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be regenerated or re-grown at a scale comparable to its consumption.

  4. Uranium- non renewable Nuclear fusion uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!

  5. COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.

  6. HOW IS COAL MADE ???

  7. HOW ARE OIL AND GAS (part of petroleum) MADE ???

  8. WHAT WAS THE DIFFERENCE BETWEEN COAL AND OIL/GAS?

  9. What is petroleum then? a liquid mixture of hydrocarbons that is present in certain rock strata and can be extracted and refined to produce fuels including gasoline, kerosene, and diesel oil

  10. HMMMM.... What are renewable resources?

  11. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time. ● Solar ● Geothermal ● Wind ● Biomass ● Hydroelectric and tidal

  12. SOLAR Energy from the sun is used to power the movement of electrons which results in electricity. Germany: 47% of its energy is solar, next Spain (16%) and Japan (13%)

  13. GEOTHERMAL • The earth’s core is hot and molten. It’s energy will last for millions of years still. • Iceland (30% of consumption of all electricity) • Downtown Toronto skyscrapers- use coldness of lake Ontario for air conditioning

  14. WIND Energy from the wind. The turning blades are attached to a turbine- a large magnet surrounded by thousands of copper coils. The wind itself is the result of unequal heating of different surfaces. (UK 50%, Denmark 21% of energy consumption)

  15. BIOMASS Energy from burning organic or living matter. The organic matter like corn, switchgrass, garbage, algae…is renewed in 1 season. Brasil (43% of cars run on biofuel) Kenya derives about 75%, India 50%, China 33% and Brazil 25% of their total energy from biomass

  16. HYDROELECTRIC, TIDAL and OCEANIC Energy from the flow of water. The sun provides the energy to evaporate the water again, reform clouds and precipitation to take place again thus renewing the water behind the dam. The sun and the moon cause tides and waves. Bay of Fundy…tidal power in Canada Interest in wave and tidal energy systems is gathering pace as a huge number devices come to the market

  17. SUMMARY Non-renewable resources like coal and oil are molecular compounds made millions of years ago by living things. A few of the renewable resources are molecular compounds like biomass and garbage made by living things a few months or years prior.

  18. Many of the non-renewable resources are used and transformed in manufacturing to produce mostly non-recyclable products like plastic, paint, adhesives, clothing, solvents… • If NON renewable resources run out, we not only run out of fuel…we run out of almost everythingmanufactured!!! • The Great Garbage Patch • (Pacific ocean) • http://www.youtube.com/watch?feature=player_detailpage&v=Co43TXJXryI • http://www.youtube.com/watch?v=Nh6lkv1udb0&feature=player_detailpage

  19. Pencil case… made of plastic…unless you choose otherwise • Cucumbers bought at Longo’s…3 cucumbers individually wrapped in plastic and then rewrapped as a group of three… in plastic • Choose biodegradable and recyclable where possible • Generally all thin, flimsy plastic is NOT recyclable…like plastic bags, plastic wrappers…

  20. Watch out…all in not what it seems • Check out the following symbols for the 7 types of plastic • What does it seem? • Why do they do that? • Ans: mislead consumers • Look for …#1 and #2...or use glass containers

  21. RRR • Reduce… minimize consumption • Reuse…choose wisely like glass containers vs plastic ziploc bags • Recycle… do your best and encourage others • Upcycling: Converting waste into stylish products • Consumer power

  22. Learn how to compost at home or use the green bin…huge difference for the environment • If it is not possible to compost yourself consider at least separating out the organic waste from the general waste and using the local green bin…it will really help reduce methane gas emissions! • Methane gas is worse than CO2 for greenhouse gas effect. Methane gas is produced when organic matter is not properly treated when decomposing. The green bin program takes care of properly decomposing the organic matter so that methane is not produced.
