Renewable Electricity Energy

Renewable Electricity Renewable electricity (RE) policy is an important subset of industrial and energy policy, and thus needs to be aligned with the energy policy priorities of sustainability, competitiveness, and security. Our common and only long-term natural advantage in the energy sector stems from renewable electricity resources such as wind, biomass, and ocean energy.
Climate change mitigation and security of supply have become the focus of many recent national electricity policies. Renewable energy resources can play an important part in addressing both of these concerns.

Against a current background of high and volatile fossil fuel prices and strong demand growth for electricity, this page focuses on one aspect of sustainable energy, namely renewable electricity.
Consumers demand secure, dependable and competitively priced electricity and producers must be responsive to these market requirements.
The combination of increased demand for renewable electricity and security of supply is a very powerful driver of major power sector change worldwide. Currently, for example, about 50% energy demand is met with imported fuels and there are projections that this could increase to 70% in the coming decades. Economic development and increasing use of electricity-consuming devices will increase future demand for electricity.
Alongside electricity demand and security of supply issues, climate change also poses a global threat. Substantial and fairly rapid decarbonisation of electricity generation and many other sectors will have to take place if the world is to have any chance of staying within the 2 degree C goal for limiting the effects of global warming.


The key components of such a vision are:
  • A regional power system based on a SuperSmart Grid;
  • The rapid scaling up of all forms of renewable power, with the ultimate goal of decarbonising electricity generation in Europe and North Africa;
  • A unified European power market that is united with the North African one, allowing for the free trading of electricity between all countries;
  • The production of renewable electricity at the most suitable sites by the most suitable renewable electricity technologiesRenewable Electricity Resources
    Resources and technological applications that may qualify as a source for Clean or Renewable Electricity production are listed below:
    Biogas Energy - means renewable electricity generated from a system that captures biogas for combustion or conversion to electricity. Biogas means the gaseous products (primarily methane and carbon dioxide) produced from organic waste material. Facilities producing biogas include landfill sites, sewage treatment plants, and anaerobic digestion organic waste processing facilities.
    Biomass Energy - means renewable electricity generated from the combustion or gasification of organic materials. Biomass includes, but is not limited to:
    • Clean wood biomass, meaning
    • wood residue within the meaning of the Forest Act,
    • wood debris from logging, construction, or demolition operations,
    • organic residues from pulp and paper production processes, and
    • timber, within the meaning of the Forest Act infested by the mountain pine beetle;
    • Liquid fuels derived from biomass including bio-oil, ethanol, methanol, and bio-diesel;
    • D edicated energy crops; and
    • Clean organically sourced material separated from municipal solid waste (MSW) and processed to serve as a combustion fuel.
    Clean biomass does not include organic material that has been treated with inorganic substances such as paints, coal-tar creosote, pentachlorophenol or chromated copper arsenate, to change, protect, or supplement the physical properties of the materials.
    If a facility co-fires fuels, or uses a mix of fuels that includes fossil fuels, only the proportion of the total electric output that can be attributed to the use of a clean or renewable fuel source qualifies as clean or renewable electricity. The proportion of the total electric output that qualifies as clean or renewable electricity must be calculated based on the proportion that clean or renewable energy constitutes of the total energy input used by the renewable energy system to generate renewable electricity, or if practicable, separate metering.
    Energy Recovery Generation (ERG ) - means renewable electricity produced from the recovery of waste energy from an industrial process that would otherwise have been vented or emitted into the atmosphere. ERG represents a net environmental improvement relative to existing energy production because it uses the waste of other processes to generate electricity. Therefore, all output from an ERG facility is considered Clean or Renewable Electricity.
    Geothermal Energy - means renewable electricity produced using the natural heat of the earth and all substances that derive an added value from it, including steam, water and water vapour heated by the natural heat of the earth and all substances dissolved in the steam, water or water vapour obtained from a well. This does not include hydrocarbons or water that has a temperature less than 80°C at the point where it reaches the surface.
