Novel classification of energy sources, with implications for carbon emissions

Abstract

The transition of the energy sector from using conventional sources to sustainable sources paves the way for the exploration of various new energy sources. Since the past classifications are often based on subjective criteria such as whether an energy source is either renewable or fossil fuel. This causes to lack of representation of emerging energy sources such as vibration, acoustic and human heat, etc. Also, the by-products of energy systems after useful conversion such as discharged heat from turbine and exhaust flue gases are never considered as a source but rather called energy efficiencies feature of the system. The current classification uses facts-based objective criteria to classify the energy sources as renewable, reserve, and capture energy sources. The terms and definitions to annex energy sources under a particular category are theoretically justified. Another important aspect that is, to meet sustainable development goals the need to choose low carbon emissions as the primary criteria for promoting energy source utilization and economic policymaking is insisted.
