Renewable energy technologies supply renewable or low carbon heat and electricity to your home. These systems are particularly good for homes where mains gas is not available because they can replace more expensive forms of energy such as LPG, oil, solid fuel or electricity. Not only will they save on your fuel bill they may generate an income and reduce the carbon dioxide that is emitted into the atmosphere.
Technologies that you may be able to install include:
- Micro Combined Heat and Power (CHP) (for heating, hot water and power)
- Air Source Heat Pumps (for heating and hot water)
- Solar thermal panels (for heating and hot water)
- Biomass boilers (for heating and hot water)
- Solar Photovoltaic panels – also called Solar PV (for power)
- Wind turbines (for power)
- Hydro power (for power)
- Anaerobic digestion (for power)
To learn more about all of these technologies, visit the Energy Saving Trust website
Generating Income from Renewable Technology
Two types of income can be generated to help cover the costs of the installation:
- The Smart Export Guarantee (SEG) is administered by Ofgem and pays households for electricity exported to the grid from a range of technologies including solar PV, wind, hydro, micro combined heat and power and anaerobic digestion. To be part of the scheme you will need to contact the participating energy suppliers. You don’t have to use your current energy supplier to receive SEG payments so it is worth shopping around. Some tariffs may also allow for payments to be made if you export from a battery.
- The Renewable Heat Incentive (RHI) – Domestic RHI closure – The Domestic Renewable Heat Incentive Scheme (DRHI) in Great Britain has now closed. The DRHI closed to new applicants including metering and monitoring service package applications at midnight on 31 March 2022. Only applications following a change of ownership can be made now that the scheme has closed.
- If you’re a business interested in the non-domestic RHI, visit the Ofgem website for more information and to view the current tariff rates.
