The Technology page has an overview of all of our low and zero carbon technology articles. Alternatively follow one of the links below.

Here is an introduction to the subjects covered on our LZC pages

• Solar Thermal - Solar hot water system descriptions and design information. We have included a typical installation schematic.
• Photovoltaics - Photovoltaics (PV) work by converting the sun's energy into electricity. Learn more here about the different types available and their performance.
• GSHP - These systems work by taking low level retained heat from the ground and boosting it for heating a property and water for domestic use. Includes design information on boreholes and typical costs.
• ASHP - Air Source Heat Pump systems can be highly efficient delivering up to 250% seasonal efficiency.
• Biomass - Biomass fuel usually takes the form of wood pellets or wood chips. The burning of wood is considered to be a carbon neutral process since the CO₂ released when energy is generated, is balanced by that absorbed during the fuel's production.
• Windpower - Information on the design and use of wind generated power
