Energy Needed to Power Civilization

The numerical results of my calculations show that the quantities of energy required for permanent survival and communication are surprisingly modest. For a society with the same complexity as the present human society on Earth, starting from the present time and continuing forever, the total reserve of energy required is about equal to the energy now radiated by the Sun in eight hours. The total energy reserve contained in the Sun would be sufficient to support forever a society with a compl...

Look inside any large office building and see how many people spend eight hours a day following the instructions on their display screen to the point of damaging their vision and injuring their hands from the strain. What ar...
