Energy equivalents:
1 gal of gas = 6.3 pounds --> 19 lbs of CO2
1 gal of gas = 31 kwhr of energy
20 to 40 kwhr per day at $0.10 per kwhr --> $2 to $4 day of electricity
net energy:
CO2 equivalents
Major Concepts from Chapter 16
net energy (Figure 16-4)
compare energy resources to mineral resources
approximate energy requirements for world and USA
projections for energy consumption
sources of oil and what it is turned into (fig 16-5)
natural gas, why it's better than oil or coal
ANWR - pros and cons
CO2 emissions per unit of energy by different fuels (Figure 16-8)
tar sands and shales
coal - different forms, use to create synthetic fuels
nuclear energy - simple pros and cons
