A benchmark that explains why green NGOs want to promote energy sobriety

The fashion for saving energy, which assumes that human behaviour can compensate for the inelasticity of energy demand, is not new. Only the name is. In 1924, when US President Calvin Coolidge proposed saving oil because he had been told that reserves would soon be exhausted, he devised a strategy called energy conservation. Though compassionate and generous, these methods failed to reverse the continuing growth in energy demand. Energy consumption, and oil consumption in particular, continues to rise as the world’s population grows and more people need to eat and work, i.e. consume energy. It is the task of industry and engineers to make processes and products more efficient. It has always been an ongoing quest. The Romans used massive stones to build their bridges, creating amazing monuments. Today, a similar function is performed with much lighter materials. Efficiency is normal behaviour in human activities, including the production, conversion and consumption of energy.
