Energy Challenges

Without energy (E) there is nothing, m=E/c$^{2}$. Without energy the various global economies will collapse. In fact, these economies generally require more energy every year. Where will this energy come from? What are the expected impacts of the various energy sources {\&} uses on the environment? Brief summary answers to these questions are presented, and a plea is made for more energy R{\&}D at our national laboratories and within the industrial community.
