Consider what changes you can make to your home to improve its thermal performance. Improving your home’s thermal performance may mean that you do not need as much heating or cooling as you think.
Improvements in technology and minimum standards have raised the efficiency of lighting over the past decade.
Renewable heating and cooling systems generally use both renewable energy and some input electricity (for example, from the grid or solar PV) to operate pumps or fans. Some renewable energy systems draw their energy from the environment, such as the ground (in the case of geothermal heat pumps), or supplement energy with outside air (in the case of reverse cycle air-conditioners or air-source heat pumps). Refer to Hot water systems for more information.
Water heating contributes 23% to overall energy consumption in the home. Heat pump technology can be used for water heating as well as space heating. Solar energy can also be used for heating water – roof mounted solar collectors absorb energy from the sun to heat water which flows to a storage tank.
Each solar panel has solar ‘cells’ containing silicon, which convert sunlight to direct current (DC) electricity through the photovoltaic effect. Solar PV efficiency – the ratio of the cell’s energy output from the solar energy input – is the most common measure of performance. The performance of all panels initially degrades, but should stabilise over the first year.
Batteries enable you to store energy to be used later, and can be a useful part of renewable energy systems (for example, solar photovoltaic (PV) or wind).
