1. Non-Renewable Energy

2. For thousands of years, people have used natural resources for energy. For example, the earliest known use of fire dates back to 460,000 BC somewhere in China. What other sources of energy do people use?

3. What is the difference between renewable and non-renewable energy resources?

4. Can you think of some examples of non-renewable energy?

10. COAL

11. Types of Coal

12. Lignite “Youngest” Most impurities Provides the least energy Gives off the most pollution and carbon dioxide

13. Anthracite “Oldest” Least impurities Provides the most energy Gives off the least pollution and carbon dioxide

14. We have 27% of the world’s coal supply – more than anybody else

15. Problems with Strip-Mining Heavy Machinery and Removal of Earth causes massive habitat destruction Land where earth has been replaced or around spoils is unstable Erosion Acid Drainage – minerals and coal react with air to form Sulfuric Acid – creates acid run-off and can percolate into groundwater

16. Problems with Sub-Surface Mining Dangerous for Workers Unstable Ground from filled in mine shafts Groundwater pollution Acid Drainage – minerals and coal react with air to form Sulfuric Acid – creates acid run-off and can percolate into groundwater

23. Natural Gas

24. Biogenic Pure Methane From recently decomposed materials in swamps, livestock feedlots, landfills, manure and wastewater sludge Can be used in electricity production Can be used in Natural Gas Pipelines IF refined Using Biogenic Methane from a Landfill Using Biogenic Methane from a Landfill Thermogenic Mixed with other chemicals from crude oil Forms in a similar way to crude oil

25. Natural Gas Cleanest of the Fossil Fuels Smallest Supply of the Fossil Fuels Biogenic can be somewhat renewed – but still contributes to carbon dioxide emissions
