Energy and Money Energy and Money SimulationSimulation

• This is a simple simulation that This is a simple simulation that allows you to build coal plants allows you to build coal plants and wind farms and then you get and wind farms and then you get to see how much energy and to see how much energy and carbon dioxide (COcarbon dioxide (CO22) they ) they produce.produce.

Notice that:Notice that:• Energy is in megawatts, money Energy is in megawatts, money

is in million US dollars, and COis in million US dollars, and CO22 is in billion pounds.is in billion pounds.

• Every second, 0.1 years passes. Every second, 0.1 years passes. You have 5 years to get as much You have 5 years to get as much energy as you can.energy as you can.

• Hold your mouse over part of the screen and type Hold your mouse over part of the screen and type “W”. This buys a wind farm and puts it at that “W”. This buys a wind farm and puts it at that location. Your money goes down a little and you location. Your money goes down a little and you start producing energy. You are not producing COstart producing energy. You are not producing CO22..

• Hold your mouse over part of the screen and type Hold your mouse over part of the screen and type “C”. This buys a coal plant and puts it at that “C”. This buys a coal plant and puts it at that location. Your money goes down a lot and you start location. Your money goes down a lot and you start producing a lot of energy. You start producing COproducing a lot of energy. You start producing CO22..

• As you produce energy, you get more money to As you produce energy, you get more money to spend on wind farms and coal plants.spend on wind farms and coal plants.

Let’s Analyze the Let’s Analyze the SimulationSimulation

• Note that the script for the coal Note that the script for the coal plant is very simple: plant is very simple: when I start when I start as a clone, go to the mouse as a clone, go to the mouse pointer.pointer.

Add to the simulationAdd 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.
