Finite resource ->Final answer is 0
Exponential growth CANNOT be sustained in a World of FINITE resources!!

digestion
thermal
A key question to consider is with what EFFICIENCY can each of theseConversions be accomplished (Useful energy output/ total energy input)

Seoinchon (?) Power plant: 57%
i.e. for every 1000J ofenergy that comes into the plant (as naturalgas), only 570 J, or onlya bit more than half, goesout as useful electricity.In the next chapter, wewill see that conversionson down the line are alsoless than 100% efficient. Conventional power plantsmay be closer to only 35%-40% efficient!

NOTE: only 13% gets to the wheelsand ALL of that goes to thermalenergy (eventually)

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?
