What is Energy?

• Comes from two Greek words
• En - In
• Ergon - Work
• Energon Energy
• Energy ability to do work

6
So What is Work?

• Work is the ability to move an object using a
  force.
• When a force moves something through a distance
  work is done
• Wfd and is measured in joules

8
Kinetic Energy

• The Greek word for movement is Kinema
• Sounds like Cinema or moving Film which is
  derived from kinema.
• Kinetic energy is the energy of movement.
• Everything that moves has kinetic energy

9
Newtons First Law of Motion

• Objects keep on doing what they are doing.
• Inertia - the resistance an object has to a
  change in its state of motion.
• A force is something that changes the motion of
  an object. Push or pull
• Fma and is measured in newtons.

10
Potential Energy

• Energy of position or stored energy
• Gravitational
• PEmgh
• 9.8m/s2
• Elastic
• Rubber Band
• Magnetic
• Electro static
• Chemical
• Battery, Gasoline, Plants
• Nuclear
• Emc2

Mission 1 Critical Current Defining Energy
Explore the types and forms of energy.

18
Mission 2 Waves of Change Calculating
Transfers and Transformations
Understand how energy is transferred and
transformed in predictable ways.
19
Energy Transfer

• Energy transfers take place when energy stays in
  the same form but is passed between different
  objects.

20
Energy Transformation

• Happens when energy changes forms
• Can occur within an object, or between objects.

21
Coefficient of Restitution

• The COR is a mathematical measure of elasticity
  or in the case of a ball how well the ball will
  rebound when dropped from a height.
• COR Sq. Root of Bounce Height / Drop Height.

22
Conservation of energy

• Energy is neither created or destroyed it is only
  transferred or transformed

23
Waves

• Progressive disturbances that transfer energy
  from one place to another
• Mechanical - must travel through a medium such as
  air or water.
• Ocean waves
• Sound waves
• Electromagnetic - do not require a medium and can
  exist in space.
• Electromagnetic spectrum

24
Light Energy
25
Tsunami

• Japanese for Harbor Wave
• A very large ocean wave caused by an underwater
  earthquake, volcano, or landslide.
• They can move at speeds of 550mph but can have a
  low amplitude and not even be noticed in deep
  water.
• As they approach the shore the waves slow down
  and increase in height changing the kinetic
  energy of the water to potential energy.

26
Fast Fact

• The highest tsunami on record happened in Alaska
  in1958.
• Caused by an earthquake that triggered a
  landside.
• Caused a wave that was estimated to be as tall as
  a 10 story building producing a splash that was
  500 feet high.

29
Predicting Tsumamis

• Dr. Titov uses data from tsunami events to
  improve computer models.
• Also collects data as earthquakes happen.
• Monitor data from 46 deep-ocean assessment and
  reporting of tsunamis (DART) bouys.

Mission 3 Power to the People The Current
State of the Grid
Understand how energy is currently generated
and distributed.
31
Energy PortfolioOur Energy Resources and how we
use them
32
Coal Resources

• Based on Government research
• May have only 150 years of coal left.
• Demand for coal may increase 67 over next 20
  years.
• CO2 emissions will increase by same .

33
Mission 4 Energy IndependenceThe Quest for
Sustainable Resources
Investigate the potential options for a new
energy portfolio.
34
Mission 5 Energy Security Powering our Future
Create a blueprint for a secure energy future
35
Energy consumption is based on energy demand

• The U.S.is the worlds largest consumer
• We use 100 quadrillion Btu of energy each year
• 1/5 of the total world consumption while only 1/5
  of the population

36
Diversify our Energy Portfolio

• Renewable
• Solar
• Hydroelectric
• Geo-Thermal
• Hydrogen
• Wind
• Waves
• Tides
• Biofuel

• Non-renewable
• Coal
• Oil
• Natural Gas

37
Reduce Our Carbon Footprint
38
Develop Biofuels

• Biofuels are a renewable, carbon based energy
  source
• Plants and algae are the original sources of oil
  and gas.
• Digestive system of plant eating animals contain
  huge populations of cellulose digesting microbes.

39
Biofuels

• Dr. Keller studies animal scat.
• He is Looking for cellulose digesting bacteria
  that break down cellulose into simple sugars.
• These sugars are fed to yeast which produce
  ethanol through fermentation.

40
Advantages and Limitations

• Combustion of biofuels produces no net CO2
• But land once used to grow food is now being used
  to grow plants for energy
• Burning biofuels does produce some pollution,
  Nitrous oxides and CO

41
Dr. Kellers Goal

• Make biofuels from sustainable crops such as
  switchgrass and poplar trees.
• Improving crop yields and trying to reduce the
  amt. of fertilizer and water put into growing the
  crop.
