Energy taxonomy: classifications for the energy transition

Despite the growing importance of renewables such as solar and wind in global energy discussions, a key challenge remains; the lack of standardized energy statistics is hindering the comparison of data across nations, energy sources and time. The International Renewable Energy Agency has therefore proposed its own comprehensive energy taxonomy to unify and clarify energy data, which is vital for effective policy-making and international collaboration. Current energy classifications inadequately address the nuances of renewable energy sources, especially in the context of the climate crisis. IRENA's proposed taxonomy focuses on the critical distinction between renewable and non-renewable energy sources. It goes beyond traditional classifications by categorizing synthetic fuels like hydrogen based on their origins, and introducing a new segment for energy storage to bring clarity to the diverse sources of energy used in storage technologies. This report proposes a comprehensive classification of energy sources and products to address the lack of standardized global energy statistics – an issue that continues to undermine effective policy-making and international collaboration in the context of the energy transition.
