1. Natural Gas PRESENTED BY SARAH SHAQUOYA & NICK

2. Questions to Consider  Where are the nonrenewable sources of energy located?  How easy is it to gain access to these sources?  What are the consequences of using these sources (fuels)?  What are the costs (direct and indirect) of using these sources?  Are there viable alternative sources of fuel?  What is the current cost of crude oil and other forms of energy?  What else have you learned about these resources?  What is the political environment for these energy sources?

3. Natural Gas  Fossil fuel  Gas with mixtures of methane, carbon and other chemicals  Energy source  Beneath the earth

4. Usage  Power generation  Fertilizer  260,000 homes across the North Island for cooking, space and central heating.  Commercial Applications: hotels, motels, restaurants, office buildings

5. Sources& Methods  Drilling  Coal beds  Shale  Power plants

7. Fracturing http://www.youtube.com/watch?v=VY34PQUiwOQ

8. Cost  Natural gas still has relatively low capital costs and favorable heat rates for new power generation plants over oil and coal.  The extraction of oil and coal is too expensive compared to the many different ways that natural gas can be produced.  Cost of natural gas is slowly increasing as consumption is also increasing each year

10. Future Outlook  World energy consumption is estimated to grow by 56 percent from 2010 to 2040.  Global natural gas consumption increases by 1.7 percent per year.  By 2040, the natural gas consumption is expected to grow by nearly 64% globally.  Emergence of more developing countries  Natural gas is estimated to grow in production due to:  Technological innovations  New reserve discoveries

11. Storage & Transport  Low density: not easy to store or transport by vehicle  Underground

12. Advantages  Burns clean compared to cola, oil (less polluting)  70% less carbon dioxide compared to other fossil fuels  helps improve quality of air and water (not a pollutant)  does not produce ashes after energy release  has high heating value of 24,000 Btu per pound  inexpensive compared to coal  no odor until added

13. Disadvantages  Not a renewable source  Finite resource trapped in the earth (some experts disagree)  Inability to recover all in-place gas from a producible deposit because of  Unfavorable economics and lack of technology  It costs more to recover the remaining natural gas because of flow, access  Combustible  Toxic

14. Saftey  Never keep flammable liquid or any combustible material near your furnace or water heater  Maintain pipes  Install earthquake valves on your house piping that will automatically shut off gas in the event of an earthquake

15. Discussion  Any Questions ????
