In a few yeras, I believe that energy wil become more expensive. Not just gas prices, but also electricity and many other sources of energy will also begin to inflate in this twenty first century. the government isn’t looking like it will do much about that, and the oil conglomerates in the middle east seem to be happy with the way things are now (and are even willing to push it further at our expense). That is why I think it is very important to start converting to, if not even developing, cleaner source of energy that are sustainable, have little damage and effect on the environment, and will leave a clean Earth to our descendents. One such system I use is earth4energy, which taught me how to harvest solar energy and wind energy for my home. It has saved me hundreds, if not even thousands of dollars on energy bill by this point.
