Yesterday, we began our exploration into the world of coal, as it's the primary resource for our electricity generation.
Here's some math to do for all my math homies out there:
The average home in the United States uses 5 tons of coal.
1 ton= 2,000 lbs
1 lb. of coal = 1 kwh = .10 on our electric bill
We pay about $10,000 on electricity bills at the Arthur Morgan School.
The utilities company says about 90- 95% of this energy comes from coal burning power plants.
Can you determine how many tons of coal our school uses?
How does it compare to the average house, considering that we have 17 buildings, 12 of which we use regularly?
