WHICH WILL WORK BEST FOR YOU?

‘BY 2030, IT IS EXPECTED THAT 50 PER CENT OF ALL SCOTLAND’S ENERGY WILL COME FROM RENEWABLE SOURCES’

Wind turbines

Unrealisti­c for an urban setting but domestic wind turbines can generate useful amounts of electricit­y for rural self-builders if their site is suitable. Location is everything – not just for your house but for the turbine too.

Hydro turbines

The force of flowing water can be converted into kinetic energy in a turbine to drive a generator. If you have the river or stream it is a reliable, predictabl­e and timeproven method of generating energy right back to the water mill.

Solar photovolta­ic

Converts sunlight into direct current electricit­y by using semiconduc­tors; even in Scotland a south-facing roof can produce impressive results.

Solar water heating

Expect to use extra heating in the winter but a useful way to reduce costs. Flat plate collectors can be fixed on the roof tiles or even integrated into the roof.

Hybrid PV-solar water heating systems

Solar thermal collectors and solar PV in one; the panels create electricit­y and produce hot water – two for the price of one.

Energy storage systems

Heat or electric batteries reduce your bills by storing the energy your renewables generate as heat and hot water. Home battery storage is the next big thing with lots of innovation­s taking place.

Heat pumps

Air source to water, ground source to water, water source to water, or hybrid air source to water. It all depends on the size of home, grounds, location and available water sources. Each system is as unique as the property it serves.
