Without energy, nothing exists including us. From the birth of our being we sought energy in the form of food to fuel our bodies, so that we may hunt and gather for more food energy. Most other applications of energy sought from those times were sought and obtained to allow us easier ways to fuel our bodies with our survival contingent food and water. It is ironic that the fuel we most heavily depend on today to produce the food energy we need in order to exist...is bankrupting us, enslaving us, killing us, and holding us, and we all know why. It does not make sense to me, common or otherwise.
