In 2012, every second, 1,039 barrels of oil and 107 cubic metres of natural gas were consumed. Mean global energy consumption per capita is 60Gj and it is estimated that by 2030 the energy demand will increase 50%. This estimate can be quite impressive when we look at the amount of energy that will be required less than twenty years from now. The response to the growing energy demand is of two types, two different roads that are not alternative, that must be followed on parallel lines. On one hand the use of renewable sources that are less polluting must be promoted for the production of energy, on the other it is necessary to introduce a new energy and energy saving culture. Energy is not something that can be drawn on endlessly, it is a precious good, and must be used with care and with a rational attitude.
