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

  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

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

  7. 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

  8. 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

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

  10. 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

  11. 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

  12. 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

  13. Discussion • Any Questions ????
