Sources of energy and global patterns

The global energy mix is made up of both finite (fossil fuels and nuclear power) and renewable sources (e.g. HEP and wind) in which they vary, depending on their availability over time and space.

Energy Mix is the relative contribution of different energy sources to a country’s energy production/consumption

 

Oil

Coal
