100% Renewable Energy

100% Renewable Energy means an energy system where all the energy used is sourced from Renewable Energy Sources.

Renewable Energy Sources

Renewable Energy Sources means naturally replenishing non-fossil sources of energy, including but not limited to [regenerative biomasses (wood, municipal waste, biomass and landfill gas, ethanol, biodiesel), hydropower and tidal power, hydrothermal power, aerothermal power and geothermal power, wind, and solar].

Drafting notes

The definition of 100% Renewable Energy can refer to individual, organisationwide or national energy systems as required.

Further definitions from Directive 2009/28/EC on the promotion of the use of energy from renewable sources:

  • Aerothermal energy means energy stored in the form of heat in the ambient air.
  • Geothermal energy means energy stored in the form of heat beneath the surface of solid earth.
  • Hydrothermal energy means energy stored in the form of heat in surface water.
  • Biomass means the biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries including fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste.
