Too Many Joules!!

The latest assignment for Extd.120 is to calculate our energy use over the course of three days. The assignment is purposefully vague, to challenge you to think about every little thing that you use that uses energy. In my calculations, I chose to include time using/doing: lighting, laundry, laptop, phone, and printer. I consciously did not include meals, heating/cooling, and whatever else may use energy to help me live nicely. I didn't even know where to begin calculating those estimations.

First, here are some assumptions that I made in order to do the calculations:

Incandescent lightbulb = 60W

Room lighting = 3 bulbs

A room in academic buildings = 10 bulbs

Lulu = 50 bulbs

Bates = 50 bulbs

Campus Po = 50 bulbs

In calculating the number of bulbs in Lulu & Bates, I estimated only immediate lighting. So, only lighting that would have directly affected what I was doing in that space. If I had calculated the lighting of the entirety of each building, my total would have been way higher. 

Printer = 2x the power required to run a laptop (60W - see previous blog post)

Phone = 1/8 the power required to run a laptop

Power required to do laundry = power required to run fridge (14,400W - see previous blog post)

Below are my results!

(sorry about the formatting issue...)

Grand Total: 205,362,000J

That is a lot of joules....I was amazed at how much larger the Monday total turned out compared to Sunday & Tuesday. It seems that laundry makes a huge difference. Also, time spent in my room is energy wasted. Lights are on in the public buildings no matter what, whereas having lights on in my room is a choice. This data definitely made me do a double-take...and this is only over 3 days!
