Once you have reduced your energy demand to a more efficient baseline, you are in a better position to investigate alternative renewable sources of energy. This stage will generally involve more significant capital cost, so there is really no point in paying for infrastructure to generate energy that you don’t really need!
The options you have here are:
- solar photovoltaic energy production
- wind powered energy production
- solar hot water
- heat pumps
Renewable energy supplies for personal use
When rooftops have good solar access, individual owners often wish to install solar hot water or solar photovoltaic systems for their personal use.
Generally a rooftop is part of the owners corporation’s common property - even for townhouses.
In many apartment buildings the total area with good solar access is also small, relative to the number of lots in the building.
There are a number of considerations and approvals necessary for solar installations for personal use.
