1. Path to the New Energy Efficient Economy

2. What on Earth Are These? World Energy Use World Population World Gross Income

3. Converting Heat to Work Since pre-history we knew how to: Work Heat Industrial Revolution to: Work Heat

4. Newcomen’s Steam Engine ~1712

5. Revolutionary Change Transforms  Economy: textile production increases 150 fold and prices drop 90%  Place: cities grow from 5% to 50%  Family: parents leave home to work  Geography: steam ship and railroad  Technology  Population

6. Economic Explosion  Pre-industrial revolution per capita annual income: $600  Industrial revolution US/Europe income $600 to $18,000  Increases 30x!

7. Energy Revolution Creates Modern World

8. Single Most Important Event in Human History

9. We’ve Come a Long Way…  Newcomen’s steam engine: 0.5%  Watt’s steam engine: 1%  Gasoline engines: 30%  Coal Rankine cycles: 35%  Turbines: 40%  Diesel engines: 50%  Combined-cycle turbine/Rankine engines: 60%

10. But Energy Conversion Largely Unchanged… 1. Use hydrocarbon fossil fuels 2. Employ combustion to release heat CH 4 +2(O 2 + 3.76 N 2 )=CO 2 +2H 2 0+(NOx+SOx+…) 3. Convert heat to work via thermal expansion
