1. Energy: The Basics

2. Energy The ability to do work Types of Energy
Mechanical (kinetic & potential)
Heat/Thermal
Radiant
Chemical
Nuclear
Electrical

3. Thermodynamics 1st Law of Thermodynamics — 2nd Law of Thermodynamics —
The lower the quality, the harder it is to convert it to work.
conservation of energy
energy goes from high quality to lower quality--heat. Entropy

4. “Saving” Energy
Efficiency: getting more output from a given amount of input
Ex:
Conservation: Using less input.
Cogeneration: The capture and reuse of waste heat.
getting more mpg by tuning engine
Turning off lights when leaving a room
Garbage incineration produces heat, can be used for electrical production.

5. Measurements of Energy
joule: energy to move 1 kg the distance of 1m
calorie: energy needed to raise 1 g of H2O 1oC
1 cal =4.2 J
watt: unit of power. Joule/second
1 kilowatt (kW) = 1000 watts
Kilowatt-hour (kWh): unit of energy
1 kW used for 1 hour
1 btu (British Thermal Unit) = 1,055 joules
Used to describe heat (energy) content of fuels

6. Ex: If a kWh if selling for $0
Ex: If a kWh if selling for $0.14 in NJ (2007 avg), how much does it cost to run a 60 watt lightbulb for 2 hours?
If the average house in NJ used 730 kWh monthly, what would be the cost?
The average household in TN used 1340 kWh, yet paid $ monthly. What was the rate per kWh there?
