Renewable energy technologies like solar panels, wind turbines, and biomass heaters are becoming increasingly popular. These are effective alternatives to fossil fuels and will help you to meet your own energy requirements and reduce your home's carbon dioxide emissions.
Grants may also be available to offset against the cost of installation. Further details of these grants are available on the BERR microgeneration website.
The Energy Saving Trust offers a guide to how renewable energy works.
Solar Photovoltaic (PV) uses energy from the sun to create electricity to run appliances and lighting. Get more information on generating electricity from PV.
Small scale wind turbines use the wind's lift forces to turn aerodynamic blades that turn a rotor which creates electricity.
Solar water heating uses energy from the sun to work alongside your conventional water heater.
Ground source heat pumps (GSHP) transfer heat from the ground into a building to provide space heating and, in some cases, to pre-heat domestic hot water
Hydroelectrical power systems use running water turning a turbine to produce electricity. A micro hydro plant is one that generates less than 100kW.
Biomass is produced from organic materials, either directly from plants or indirectly from industrial, commercial, domestic or agricultural products.
A Combined Heat and Power (CHP) device simultaneously generates both heat and power and is a mature technology widely used in industry. Recovering the heat from a power generating process leads to high overall efficiencies.
