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 this background of increasing fossil fuel prices and remarkable energy growth demand, this page focuses on 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 per cent of energy demand is met with imported fuel and there are projections that this could rise to about 70 per cent in future decades. Economic development and increasing consumption of electricity-consuming equipment will increase the demand for future electricity.
Alongside electricity demand and security of supply issues, climate change also poses a global threat. Large scale decarbonisation of electricity generation and many other sectors will have to occur if the planet is to stay within the 2 degree C target for limiting global warming effects.
The key components of such a vision are:
Renewable Electricity Resources
Resources and technological applications that may qualify as a source for Clean or Renewable Electricity production are listed below:
Biogas Energy - refers to renewable electricity produced from a plant that mostly captures biogas for conversion to electric power. Biogas refers to the gaseous constituents (mostly methane and carbon dioxide) are produced from solid organic waste. Facilities producing biogas fuel include municipal garbage landfill sites, common sewage treatment facilities, and anaerobic deterioration of organic waste processing plants.
Biomass Energy - refers to renewable electricity generated from the burning of organic materials. Biomass includes, but is not limited to:
Energy Recovery Generation (ERG ) - refers to renewable electricity generated from the recovery of industrial waste energy that would otherwise be emitted into the atmosphere. ERG represents a net environmental benefit relative to existing energy production because it uses the waste output of other industrial processes to generate electricity. Therefore, all energy output from an ERG plant is considered renewable.
Geothermal Energy - refers to renewable electricity produced using the natural heat of the earth, including steam, water and water vapour as well as all materials dissolved in the steam, water or water vapour.
