Energy Ability to do work Many types of energy Energy is always conserved: Work Input = Work Output Energy is transferred by forces to other kinds of output Total input = total output, though the output will never be 100% efficient

Step Back Often we can’t see the forest from the trees Everything is a system wrapped within other systems, micro to macro Natural, from the life cycle of a micro- organism, to the ecosystem it lives in, to the system of planets, galaxies and the universe itself

History & Technology

Historical Developments Power for the Industrial revolution Phase I – Mechanization Maximizes inventions using mechanical devices powered by kinetic energy – i.e. flowing water and also human and animal power Phase 2 – Steam Early piston-driven engines appeared in 1700’s (Newcomen) and greatly improved in 1787 (Watt); in 1800’s locomotive & steam boats Phase 3 – Electricity Wikipedia Industrial RevolutionIndustrial Revolution

External Combustion A Watt steam engine, the steam engine that propelled the Industrial Revolution in Britain and the world.Watt steam enginesteam engineBritain

Modern Era Takes Off Harnessing and controlling electricity Battery – 1800 (Volta) Electric generator – 1831 (Faraday) Niagara Falls power plant 1900power plant Transportation Steam engines Internal combustion engines lead to automobiles

Electrical Power Power plants Electricity created by spinning magnets inside of copper coils Same basic idea for over 100 years How you spin the magnets is the issue Steam generated Water Wind Let’s go to the video

US Fuel for Electricity

Project Briefly list and describe the various types of fuel used for electrical power generation Choose a renewable energy source How does it work? What are the benefits and drawbacks of using this fuel?\ Add resources to the wiki page, Publish/ present your work PowerPoint, web page (wiki or Google pages)
