At the end of Lyndzi's post about inelastic goods and her experince with Amtrak she asks the question, What is another major product you can think of with an inelastic demand? If the price of this item increases do you think consumers will find ways to conserve their overall use of the product?
Another product that could be seen as inelastic is electricity/utilities, we all use these daily and their isn't a alternative. Although electricity isn't nearly as expensive as oil if it gets to much for people to pay each month there could be a shift in how we use it.
Recently with Earth day and global warming problems on the rise people have been looking at their own footprints on the Earth a little differently. However big these problems might be, people will not change their daily routines until it directly effects them. A problem with money could lead a person to cut back on their spending and keep a closer look at their finances. With the price of using your appliances possibly getting higher I could see a slow movement towards conserving their use. This would allow many benefits to the user and to their environment.
