Renewable resources are replenished either by:

  • human action - eg trees cut down for biofuel are replaced by planting new trees
  • natural processes - eg water let through a dam for hydroelectricity is replaced through the water cycle

A non-renewable energy resource is one with a finite amount. It will eventually run out when all reserves have been used up.

Different energy resources

Nine different energy resources, fossil fuels, nuclear, bio, wind, hydroelectric, geothermal, tides, sun, water waves; illustrated around a main label.

The table below shows the main features of the most common energy resources used today.
