Renewable technologies are derived from the application of the knowledge of natural systems to convert renewable resources into useful forms of energy.
The earth receives vast solar resources from the sun. To utilise this resource the following solar technologies are crucial in a sustainable energy system.
- Domestic Solar Hot Water Systems
- Solar Desalination
- Solar Cooking
- Solar Towers
- Space Heating
- Space Cooling
- Solar Ponds
- Solar Drying
- Solar Pool Heating
Wind resource has been used traditionally in agricultural and transport applications. It is now also used in power generation.
- Large Hydroelectric
- Micro Hydroelectric
- Pumped Hydroelectric Storage
- Hydromechanical Waterwheels & Hydraulic Rams
- Tidal Turbines & Tidal Barrages
- Ocean Thermal Energy Conversion (OTEC)
- Wave Energy Conversion
- Desalination (Electrodialysis, Reverse Osmosis & Nanofiltration)
Biomass, waste and geothermal technologies are proving themselves to be indispensable in simultaneously reducing environmental degradation and efficiently supplying a variety of specialised energy requirements.
In order to utilise the renewable resources in stand-alone power and distributed generation systems effectively, a range of enabling technologies are being developed in the area of power conditioning and storage.
- Fuel Cells
- Power Conditioners - Inverters and System Controllers
Many applications have been developed to utilise these technologies in a sustainable manner.
