Energy and Economics
Simulation
Computer App Session 8
Energy and Economics Simulation
Learning Objectives:
• I can research information on the
web to be used in a simulation.
• I will create a simulation that
has money in its model.
What are some simulation
games that use money?
• Farmville
• SIMS games
• Zoo Tycoon
• Rollercoaster Tycoon
Explain how money is used in
these games.
Energy and Money
Simulation
• This is a simple simulation that
allows you to build coal plants
and wind farms and then you get
to see how much energy and
carbon dioxide (CO2) they
produce.
I will demonstrate.
Notice that:
• Energy is in megawatts, money is
in million US dollars, and CO2 is
in billion pounds.
• Every second, 0.1 years passes.
You have 5 years to get as much
energy as you can.
• Hold your mouse over part of the screen and
type “W”. This buys a wind farm and puts it
at that location. Your money goes down a
little and you start producing energy. You
are not producing CO2.
• Hold your mouse over part of the screen and
type “C”. This buys a coal plant and puts it
at that location. Your money goes down a
lot and you start producing a lot of energy.
You start producing CO2.
• As you produce energy, you get more money
to spend on wind farms and coal plants.
Let’s Analyze the
Simulation
• Note that the script for the coal
plant is very simple: when I start
as a clone, go to the mouse
pointer. The script for the wind
farm is exactly the same.
• Where is the model with all the
equations?
The stage is where the code
for the model is!
• When the “w” is pressed, a wind
farm is created. Here is the
code:
When “c” is pressed, a coal plant
is created. Here is the code:
• It’s exactly the same as the wind
farm code, except it costs 2
billion dollars (2000 million) to
build a coal plant.
• The other script
• has more equations!
• There are also some yellow blocks. These
are comments. The computer ignores them,
but they are useful to someone looking at
the code. They are being used to explain
the units on the variables.
Your turn:
• Go to:
https://scratch.mit.edu/projects/50128898/
• Click “see inside”
• Click “remix”
Add to the simulation
• Add a natural gas plant to the simulation.
• First, find out how much energy it
produces and how much it costs to build
(search the web).
• Natural gas plants produce about 3.4
million lbs of CO2 for each megawatt
generated.
• So, if you are using a 625 MW plant, you
will generate about 2100 million lbs of CO2
per year.
Create a natural gas sprite
Now run the program
• Does it work?
• Save your project with today’s
date and your name and share it
to the class studio.
• Remember to turn off
commenting!
