The lack of consensus stems from the fact that there are differing views about the meaning of EE and the means of implementing it. How much one will actually benefit from EE depends on how one approaches the issue.

The chapter also presents a short overview of the current debate on EE in which the EE gap and the rebound effects are the main constitutes.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world.
