Warm Up 1. List 2 things you think you know about fracking. 2. List 2 things you want to know about fracking. Time’s Up!
Vanishing Resources Discussion Patterns in data? Why did fossil fuels spike and then drop down very low? Why did solar power grow at the end? Did anyone run out of white beans or black beans in the last round? What does running out of black beans represent? Will this happen in real life at some point? What does running out of white beans represent? What could we do to add more white beans in the future?
Fossil Fuels
Coal Fossil fuel Dirtiest burner Formed in former bog Decaying plant/ animal material Acidic Pressure and time
Where and How? Mining Deep: Dangerous, health hazard (black lung) Strip: Extreme environmental impact Refinement Transportation: Train Mostly U.S. Used for Electricity
Coal Advantages Disadvantages
Petroleum Fossil Fuel Fossil Fuel Marine organisms Brown/black thick liquid
Petroleum Extraction Drilling Fracking Refined – distillation Refined Heated to a gas Cooled to various liquids or gasses Make many different things
Trans-Alaska Oil Pipeline Why do you think this pipeline is elevated rather than buried in the ground?
Petroleum – Where?
Petroleum Advantages (Pros) Disadvantages (Cons)
Natural Gas Lighter component of petroleum. Methane Odorless gas Burns cleaner than other fossil fuels Uses Heating homes/water Cooking Transportation
Combustion Demo
Fracking Use existing well Drills horizontally Pumps in Water Sand Chemicals High pressure Breaks open rocks Releases trapped oil and gas Sand holds open cracks Chemicals aids process Products pumped out
