1st Law
 ⋅ ΔE = W + H + R
 ⋅ Same statement as conservation of energy
 ⋅ Closed system means that W(orking), H(eating), and R(adiating) are zero
 ⋅ You can’t win

2nd Law
 ⋅ Entropy (S) increases (for long periods of time/large systems)
 ⋅ This is related to the idea of Ediss ; energy cannot be concentrated without using energy
 ⋅ You can’t break even

3rd Law
 ⋅ As temperature goes to absolute zero the entropy goes to a constant that is not equal to zero
 ⋅ You can’t leave the game

 ⋅ Death of the universe
 ⋅ No perpetual motion/perpetual energy source
 ⋅ Limits to natural resources

 ⋅ Population is an increasing function
   ◊ Linear?
   ◊ Exponential?
   ◊ Logistic Curve?
 ⋅ Per capita energy use is also currently and increasing function
   ◊ Developing nations
   ◊ Developed nations
 ⋅ Therefore, the total energy usage of the world is increasing

 ⋅ Some energy sources are non-renewable
   ◊ Oil, Coal, Natural Gas
   ◊ Fixed pool f resources – a one time gift
   ◊ Increasing reserves?
   ◊ Nuclear
 ⋅ Certain other energy sources are semi-renewable
   ◊ Hydropower, geothermal, nuclear
   ◊ Slowly destroyed through use – a rich relative
 ⋅ Some energy sources are considered renewable
   ◊ Solar, wind tidal, geothermal
   ◊ No significant change over time – a steady job
 ⋅ It takes energy to get energy (EROEI)
 ⋅ Some energy is more valuable than other energy
   ◊ Concentration
  ◊ Form (solid, liquid, gas, electricity)
 ⋅ Limits the rate of transferring energy (power) are at least as important as total consumption (energy)
