Energy Use : 

Energy Use Early Societies – animals and slaves provided power http://www.worldwideflood.com/ark/technology/ox_mill_small.jpg

Energy Use : 

Energy Use 4th century – water wheel Mainly for grinding grain Later to power machines http://www.timberwolfcreek.com/pictures/waterwhl.jpg

Energy Use : 

Energy Use 7th century – windmill Grinding grain Pumping water http://www.saffronbymail.com/images/windmill.JPG?s=966391384

Energy Use : 

Energy Use 18th century - Industrial Revolution in Europe Waterwheels Windmills Factories had to be located near power source Cities located near factories http://en.wikipedia.org/wiki/Waterwheel http://www.kushaiah.com/windmill/images/windmill-c.jpg

Energy Use : 

Energy Use 18th century – steam engine invented Powered by burning wood http://z.about.com/d/inventors/1/0/-/E/steamenginesavery.jpg

Energy Use : 

Energy Use 19th century – steam engine replaces water wheel as main energy supplier Coal replaces wood as fuel http://www.sos-arsenic.net/images/forest16.jpg

Energy Use : 

Energy Use Inventions are changing the way we use energy Internal combustion engine Oil well drilling Refinement of crude oil 1. http://bancroft.berkeley.edu/Exhibits/physics/images/origins18.jpg 2. http://www.nelmes.fsnet.co.uk/paxman/plungar.jpg 3. http://media.nasaexplores.com/lessons/04-051/images/petroleum_products.jpg

Energy Use : 

Energy Use 1920 – 80% of energy in the US is provide by coal http://z.about.com/d/geology/1/0/5/F/anthracite.jpg

Energy Use : 

Energy Use Drake’s Well – Titusville, Pennsylvania http://srufaculty.sru.edu/melba.tomeo/FolkTales/drake.jpg http://www.history.rochester.edu/fuels/tarbell/WELL.JPG

Energy Use : 

Energy Use Drake’s Well Today – a local museum http://www.oilregion.org/images/Media%20Kit/Drake%20Well%20%20with%20orange%20flowers.JPG

Energy Use : 

Energy Use Today – Fossil Fuels are running out Nuclear Power Renewable Energy Water power Wind power Solar power Energy from the Oceans Energy from the Earth Energy from biomass

Fossil Fuels : 

Fossil Fuels Coal Oil (Petroleum) Natural Gas

Coal : 

Coal Advantages Cheap Plentiful US has large reserves

Coal : 

Coal Environmental Problems Mining damages surface of Earth Burning causes pollutants Global warming Acid rain production

Coal : 

Coal Safety and Heath Hazards Mine fires and collapse Mine subsidence Black lung disease

Petroleum : 

Petroleum Advantages Inexpensive Base of our current technologies Easy to transport

Petroleum : 

Petroleum Environmental Problems Spills harm habitats and water supplies Burns with heavy soot and smoke Produces toxic substances when burned Global warming

Petroleum : 

Petroleum Safety and Heath Hazards Heavy and dangerous drilling conditions Noxious fumes and vapors Toxins can be absorbed through skin Can produce CO when burned

Natural Gas : 

Natural Gas Advantages Clean Efficient Infrastructure for transport already in place

Natural Gas : 

Natural Gas Environmental Problems Explosive Greenhouse effect Carbon dioxide produced from burning Methane itself is a greenhouse gas

Natural Gas : 

Natural Gas Safety and Heath Hazards Explosive Colorless, odorless, difficult to detect Mercaptans added to create “bad” smell Replaces oxygen in air supply
