A very informative program on PBS this evening looked into alternate forms of energy and new, promising research into these that is being done all over the earth.  Definitely a hopeful view.  However, sorry to have a weird perspective, but why do we humans need to use up so much energy?  Is it because we engage in a vast array of activities that may not do a great deal of good? Maybe we should sit still from time to time, like the flowers, and just use the energy that God has given us?
