The energy mix is a group of different primary energy sources from which secondary energy for direct use - such as electricity - is produced. Energy mix refers to all direct uses of energy, such as transportation and housing, and should not be confused with power generation mix, which refers only to generation of electricity.
In 2007, the global primary energy use was oil equivalent, or . According to the International Energy Agency (IEA) 13.6% of world primary energy was used by the European Union (EU). Within the EU, 75.9% came from fossil fuels, 14.1% from nuclear power, 7% from biofuels, 2.9 from renewable energy resources.
Overall primary energy consumption in the United States in 2015 relied most on petroleum (), natural gas () and coal (). Renewables contributed and nuclear power .
In the same year, about 4 million GWh of electricity were generated in the United States, 67% of which was generated from fossil fuels (coal, natural gas, and

The energy policy of the European Union focuses on energy security, sustainability, and integrating the energy markets of member states. An increasingly important part of it is climate policy. A key energy policy adopted in 2009 is the 20/20/20 objectives, binding for all EU Member States. The target involved increasing the share of renewable energy in its final energy use to 20%, reduce greenhouse gases by 20% and increase energy efficiency by 20%.
An energy transition (or energy system transformation) is a significant structural change in an energy system regarding supply and consumption. Currently, a transition to sustainable energy (mostly renewable energy) is underway to limit climate change. It is also called renewable energy transition. The current transition is driven by a recognition that global greenhouse-gas emissions must be drastically reduced. This process involves phasing-down fossil fuels and re-developing whole systems to operate on low carbon electricity.
Explores China's environmental challenges, renewable energy, coal usage, and US-China cooperation in technology and the environment.
Discusses hydrogen's role in the future energy mix, key drivers of energy transition, challenges in modeling domestic energy demand, and integration of energy models.
Explores the 2019 costs of renewable power generation technologies, emphasizing the decreasing costs of solar and wind power.
This course examines the supply of energy from various angles: available resources, how they can be combined or substituted, their private and social costs, whether they can meet the demand, and how t
Les enjeux environnementaux doivent être abordés de façon systémique. L'Analyse du Cycle de Vie (ACV) et l'Analyse de Flux de Matière (AFM) sont des méthodes permettant d'évaluer de façon globale les
In light of the energy transition, it becomes a widespread solution to decentralize and to decarbonize energy systems. However, limited transformer capacities are a hurdle for large-scale integration
Purpose In light of the sustainable diet debate, we conducted a large-scale regionalised LCA to answer the following questions: (i) does the climate advantage hypothesis of plant-based fat spreads and
