I recently was assigned a research project by my statistics professor.  The project involved coming up with some real world statistics about U.S. households.  Some of the topics that he recommended to the class were food consumption, demographics, opinion polling, and energy consumption.  Because I am interested in energy policy I decided to focus on questions concerning household energy consumption within the USA.  I knew from previous research that U.S. households consume a larger percentage of energy than most households in other countries so I decided to focus my research on why that happens to be.  I had a suspicion that energy spent on heating and cooling occupied a great deal of energy usage for U.S. households.  Air conditioners, especially older Heating and Air Conditioning units, are energy hogs.  I came to find that homeowners spend more than $29 million each year on their air conditioners and air conditioner service.  That is a very large sum of money and a legitimately big market on top of that.  Statistics also show that three-quarters of all homes in the U.S. actually have air conditioners.  This means that there is room for the A/C market to grow, meaning there will be even more energy consumption.  Sadly, running our air conditioners comes at a high price, an estimated 117 metric tons of carbon dioxide are released into the air each and every year.  Thankfully, the Heating and Air Conditioning industry is taking steps to alleviate the impact of this pollution by designing better Heating and Air Conditioning units.  When examining the total amount of energy consumed in the U.S., I was actually shocked to learn that air conditioners use 6% of the entire amount of electricity produced in the U.S.  Even though that seems like a small number, you have to consider that is just from one appliance alone. I really never thought studying energy and A/C could be so engaging.
