  1. Today is November 7, 2012 • Get your notebook out and study your energy sources notes • We are taking a quiz today so have a book out to read when you are done.

  2. Advisory • Math Activity today • Get out a book whenever you are done

  3. Nonrenewable Resources • Resources that cannot be replaced in our lifetime and will eventually run out.

  4. Renewable Resources • Resources that can be replaced over a logical period of time, or will never run out.

  5. Wind Energy (Renewable) • Electrical energy generated by wind turning wind turbines. • Disadvantages: • Only can go in places with a lot of wind • You need a lot of turbines to make electricity • They are ugly • Advantages: • It’s free • No greenhouse gases produced

  6. Hydropower (Renewable) • Energy generated by tides, waves, and dams. • Disadvantages: • Dams are expensive • Affects nearby wildlife • No rain = no electricity • Advantages: • It’s free • No greenhouse gases produced

  7. Fossil Fuels (Nonrenewable) • Fuels found in the ground such as oil, natural gas, and coal. Will eventually run out. • Disadvantages: • Produces greenhouse gases such as CO2 (Carbon Dioxide) • Coal mines and Oil rigs are dangerous and harmful to the environment • Advantages: • Can be found in a lot of place in the world • Easy to transport • Cheap

  8. Solar Energy (Renewable) • Energy generated using solar panels to convert light and heat into electricity. • Disadvantages: • Expensive to build solar stations • Cloudy or night time there is no energy • They are ugly • Advantages: • It’s free • No greenhouse gases produced

  9. Geothermal Energy (Renewable) • Energy from heat inside the Earth • Disadvantages: • Not very many places to build geothermal stations • Harmful gases and materials sometimes come up. • Advantages: • It’s free • No greenhouse gases produced

  10. Biomass Energy (Renewable) From plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oil • Disadvantages: • Produces greenhouse gases such carbon dioxide • There is not enough space to grow biomass fuel • Advantages: • It’s cheap and from things that we usually throw away • Should not run out

  11. Nuclear Energy (Nonrenewable) • Energy from heat produced when splitting a Uranium atom through a process called nuclear fission. • Disadvantages: • Waste is Radioactive • Uranium will run out in about 50 years with our current use. • Advantages: • No harmful greenhouse gases • A small amount of Uranium produces a lot of energy
