Classification of Energy

Energy resources can be described as renewable and non renewable Renewable energy sources include

  • Wind power
  • Wave power
  • Ocean Thermal Exchange Capacity (OTEC) - based on temperature differences in ocean layers.
  • Solar Power
  • Hydro power
  • Fuel cells
  • Bio- fuels- also known as biomass fuels-such as alcohol form, sugar, methane from organic waste or charcoal from trees and biodiesel.

The key characteristics of renewable energies is that the energy sources are continually available, still some cases such as with hydro power and biomass, continuing availability requires good management – for example tree planting or river management. Other renewable like solar and wind power are available for the foreseeable future without any human intervention.

Non- renewable types of energy include all the fossil fuels – coal, oil, gas and their derivatives such as petrol and diesel. The non- renewable are finite in supply because their rate of formation is so low that they are, in reality, finite sources.
