Energy conservation is simple, and we can participate if we provide a little thought. But there are several impediments to conservation. Generally, these are the consequence of laziness, and of indifference to the effect on others. Simply put, human nature gets in the way.
People tend to do what is easy. In some cases, this is problematic. Another problem is that some people feel they have no responsibility to what happens to others. As morality declines these problems could become more severe. For many, laziness and indifference are not likely to go away just because a person learns more about the consequences of an action, but some with a moral code might simply need to see why little actions are important. Hopefully some are just uninformed, and they will change once having the problems pointed out.
