Renewable energy is that which is created from sources that can be used time and time again such as energy from the sun, water and the wind.
It can also be created from sources that can be replaced, such as wood or waste products.
Some renewable energy technologies can generate more energy than you need. They may also produce energy when you aren’t at home. In both cases you may benefit from selling your surplus energy back to your electricity company.
You can read more about financial assistance for Renewables elsewhere in this section of the website.
We have produced a leaflet, in partnership the Energy Saving Trust, which gives advice on generating your own energy.
Solar electricity panels (Photovoltaic – PV)
The production of electricity from sunlight. Commonly used to power calculators but can also be used to produce a proportion of a home’s electricity requirements.
Solar water heating
The production of hot water from sunlight. Panels are usually placed on the roof and can typically provide around 50% of a household’s hot water requirements.
Air Source Heat Pumps
An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can do this even when the outside temperature is as low as -15°C. There are two main types of systems, both of which can save a substantial amount of money and CO2 emissions.
Ground Source Heat Pumps
These use the almost constant temperature of the ground to heat your home.
A unit, much like a refrigerator in reverse, sits in your home and pumps a liquid through pipes which are dug vertically or horizontally in your garden and extract the heat. For every 1 unit of energy used to extract the heat from the ground, 3 to 4 units of energy are generated.
Small-scale wind turbines
A smaller version of the large wind turbines found off our coasts and in windy rural locations.
Small-scale hydro power
This uses the power of moving water, usually through a dam, to operate an electric generator.
This is when energy is released from organic matter such as wood (but not fossil fuels) which can be replaced over time through new planting. An example of this is a wood-fired stove. It can also include organic matter produced as a waste product of industry or farming.
Please be aware you will need to check with the Planning Section before you install any microgeneration technologies.
