In this video, we will have a closer look at the supply side of the energy system. A number of important concepts will be introduced such as Total Energy Supply (TES), and Total Final Energy Consumption (TFC). We will cover the determinants of energy use, how global energy is supplied and what role renewables currently play in this equation.

Key takeaways:

• Total energy supply is energy as extracted from nature
• Final energy consumption is the energy going to consumers
• Energy use is determined by the volume, structure and efficiency of activity
• Coal, oil and natural gas are the largest sources of global energy supply
• Coal is the largest source of electricity
• Renewables currently only contribute a small percentage to total final energy consumption
