CT: To meet its energy needs, each country uses the energy available to it in differing proportions. This is what we call the energy mix. Since the 19th century, the energy sources used to meet global demand have been mostly fossil fuels (coal, oil and natural gas). These fossil fuels are replenished only after millions of years. Their use results in an increase of greenhouse gas emissions in the atmosphere, the long-term effect of which could potentially lead to climate and environmental change with very serious consequences. Nowadays, to continue developing while preserving the environment, humanity has to diversify its energy mix.

N: 1. The term energy mix refers to the distribution, within a given geographical area, of the consumption of various energy sources (crude oil, natural gas, coal, nuclear energy and the many sources of renewable energy).
For each region or country, the composition of the energy mix depends on:

• the availability of usable resources on its territory or the possibility of importing these;
• the extent and nature of energy needs to be met;
• the economic, social, environmental and geopolitical context;
• the political choices resulting from the above.

2. In the fields of Renewable Energy and Energy Transformation: The combination of sources used to provide energy at any given time and place.
Energy sources include coal, oil, gas, water (hydro), uranium (nuclear), wind, sunlight, geothermal and others.
3. In the fields of Environmental Economics and Climate Warming and Ozone Layer, “supply mix” is a synonym for “energy mix”.
