To Be Printed Out or To Be Shown On Screen?
There is an interesting phenomenon I observed these days when I went to the ATM. I found that many people would like to choose print out rather than show on screen after check-in or check-out. From this phenomenon, there is a problem comes to my mind which relates to energy efficiency.
Energy efficiency can not only defined as to reduce the amount of traditional energy such as electricity and water but also relates to other different modes of sources. It is acknowledged that energy efficiency is a big problem among the world. So to address this problem, there are several motivations. Firstly, reducing energy cost could result in a financial cost saving which means that you could use less money to get identical energy. Second is renewable energy. The definition of renewable energy is a kind of energy collects resource from naturally replenish on a human timescale, such as sunlight, tides, waves and geothermal heat. Those resources always are seen as sustainable and eco-friendly substituted energy in four important fields including electricity, air and water heating/cooling, transportation and rural energy services.
In my blog, I will focus on the first solution which is reducing the usage of energy. In my observation, many people are like to print out their receipts which may cost paper waste when most of them just throw away without keeping those receipts. Maybe there are some people have appropriate reasons to need those bills, however, other persons who do not need also choose to print out would not help our environment protection. A good solution could be the bank should provide particular baskets placed nearby the ATM, which are only used to collect those receipts and could be used in a recycle way. This solution could help those who need papery receipts to get what they need. Another solution I suggested is to provide e-receipt, thus we could help to protect more trees and alleviate our environmental problem such as global warming.
