Our societies in the developed world are built on the assumption that energy is both freely available and relatively cheap. Our homes, offices and even recreational areas are often littered with a plethora of energy consuming devices i.e. Televisions, Computers, air conditioners, heating etc. Our lives and livelihoods have become increasingly dependent and inter-twinned with energy derived mostly from the burning of fossil fuels.
The use of fossil fuels to generate energy, and the volume of fossil fuels required to generate energy has rapidly been on the increase for the past 250 years, since the start of the industrial revolution.
