Speaking as a graduate student who has been living on her own since March, I try every possible way to be energy efficient in order to help conserve our planet as well as help my wallet! At this day and age it seems like being energy efficient is a fad or trend but it should be looked as a way of life that is here to stay. There are many resources available for people to become educated and aware of the problems that are ongoing and finding ways of fixing them. It is up to us to practice energy efficiency in order to protect the environment and save some money while were at it.
When picking a location to live for college, opt to get a place closest to campus or on campus. This way you can walk or ride a bike to class instead of driving to school. My university is a commuter school and because of that they have made a go green ride incentive where students are grouped together depending on where they live and receive better parking if they decide to carpool. Although this is not the most popular option, more and more students are turning to it. Even in my cohort, students have posted on our message board if anyone wishes to carpool. This is something that has yet to be fully developed but it is on its way.
In the community where I live, I know that we can ask for a free air filter every month. Although replacing the filter monthly does create extra trash, the air conditioner will be able to run more efficiently with a cleaner air filter. Ideally buying a reusable air filter that is replaced once a month is the best solution, but for houses or apartment complexes that dont offer free air filters, the air conditioning will work more efficiently if the filter is replaced.
