Solar Power
Energy can be generated from the sun using photovoltaic systems or solar panels. Panels can be added to roofs or buildings as long as an area faces 90 degrees south. If there is too much shade or the light is blocked by trees, not enough energy will be generated.
To buy and install a system which generates up to half a domestic property’s electricity requirements will cost around £12,500.
Wind Energy
Wind turbines use turning blades to generate electricity. Domestic wind power systems are particularly well suited to houses situated in remote areas. This is an added bonus because traditional electricity supplies can often be harder to access in these areas.
Wind turbines are best mounted on a mast or tower where wind speeds are faster. There should be no major obstructions that will break the wind, such as trees or large buildings. To check whether your property is suitable for wind energy generation, it’s usually advisable to do a long-term test on wind speeds (up to one year).
A wind energy system to suit an average house is likely to cost around £15,000.
Water Power
Energy can be harnessed from water when it is used to power a turbine. Power can be generated even from a small stream but the water source will need to be fairly close to where you live. The amount of energy that you can harness from water will be affected by how fast the water is flowing and how far it falls. You may need planning permission to install a turbine.
It is estimated that a typical domestic system will cost around £20,000 to £25,000.
More Ways to Generate Your Own Electricity
Other ways to generate electricity include:
Ground source heat pumps – This uses a ground loop, harnessing heat from the earth.
Bio-energy – Energy can be created by using organic matter (biomass) such as woodchips.
Micro CHP – Micro CHP generates electricity from fossil or renewable fuels using a furnace. It harnesses the heat that is normally wasted when electricity is generated.
