Where did it come from? Energy from plants millions of years ago layers of dead plants at the bottom of the swamps were covered by water & dirt Energy trapped heat and pressure turns plant remains into coal http://www.keepbanderabeautiful.org/coal.html

What is coal suited to do? Most commonly used to produce electricity Burned – heats water – creates steam – pressurized steam – turns turbine – produces electricity http://www.treehugger.com/renewable-energy/niagara-applies-for-a-coal-hand-out.html

What is coal suited to do? iron & steel production cement manufacturing coal tar production home heating industrial applications requiring heat http://www.mexicaliindustrialpark.com/2011/?p=4392 http://www.qrbiz.com/buy_Coal-Tar-Solution

How realistic is this energy currently? Most abundant, but nonrenewable 50% of US electricity http://someinterestingfacts.net/facts-about-electricity/electricity-distribution/

The Future of Coal Possibility of a coal powered car with nearly no emissions, including CO2. http://griid.org/2011/07/13/the-limits-of-green-capitalism-in-west-michigan/ http://www.thinkgreenliveclean.com/2010/07/electric-or-coal-powered-car-depends-where-you-plug-it-in/

The Future of Coal Liang-Shih Fan –iron-oxide pellets as an oxygen source; contain the reaction in a small chamber “oxidation” –chemical combination of a substance with oxygen. Waste - water and coal ash Metal is recyclable http://www.austpacresources.com/dri.php

The Advantages of Coal One of most abundant energy sources Relatively inexpensive. Useful byproducts iron & steel production Cement manufacture home heating Electricity http://www.jewishjournal.com/the_entrepreneur/item/thermostat_or_thermometer_how_do_you_function_20120821

The Advantages of Coal Can be stored safely to save for emergencies Power is not dependent on weather Reduces dependence on oil http://www.tateoil.co.uk/blog/2011/10/coal-vs-heating-oil-bout-three/

The Disadvantages of Coal Emits carbon dioxide, sulphur dioxide, nitrogen oxides, sulphuric acids, arsenic, ash. Can lead to acid rain Can scar landscape and cause wildfires http://www.telegraph.co.uk/earth/earthnews/5257162/Power-plants-could-store-carbon-dioxide-under-North-Sea.html

The Disadvantages of Coal requires an extensive transportation system (pollution) Limited – will be entirely depleted this millennium if we continue to burn coal. Health difficulties for miners; very dangerous to mine Pollution http://en.wikipedia.org/wiki/Miner

Questions 1. Which of the following is NOT a disadvantage of coal? Extensive transportation Health effects on miners It produces radioactive waste Pollution 2. True or False: Coal is not an abundant resource. True False – abundant and renewable False – abundant and nonrenewable

Questions 3. What is coal made of? Just Carbon Just Hydrocarbons Mostly Oxygen Mostly Carbon and Hydrocarbons 4. What is the main use for coal? Home heating Powers cars Electricity Industrial uses
