Energy Conversions (Table 2.2) digestion thermal Automatically Happens! A key question to consider is with what EFFICIENCY can each of these Conversions be accomplished (Useful energy output/ total energy input)

Seoinchon (?) Power plant: 57% i.e. for every 1000J of energy that comes into the plant (as natural gas), only 570 J, or only a bit more than half, goes out as useful electricity. In the next chapter, we will see that conversions on down the line are also less than 100% efficient. Conventional power plants may be closer to only 35%-40% efficient!

Residential Electric Power Bill $145.6/1948 kWh = $0.0747/kWh
Commercial Power Costs Energy cost estimates for a project out at IUCF: use (i.e. energy) charge: $3105/(360hr*575kW)=$0.0147/kWh peak use (i.e. maximum power demand) charge: $13.11/kW Why is this different from the residential calculation?
