2.8 Summary

This chapter has shown how society requires energy to survive and how this energy use has increased exponentially over the last century.  The implications of the majority of this energy coming from fossil fuels has been demonstrated through the effects of resource depletion (with a specific focus on peak oil) and climate change.

A sustainable energy system has been suggested, which hinges on reducing energy consumption.  This coupled with reducing wasted energy through increased efficiency and implementing on a bigger scale the use of renewable energy technologies will be necessary to keep the lights on through the next decades.
