A house that pays the bills itself and does not generate any pollution? Contrary to appearances, this is not a fairy tale at all. There are more and more reports about the creation of entire green districts that are to be entirely powered by renewable energy sources. Is such energy self-sufficiency realistic? Check what is worth knowing about this topic.
What is a self-sufficient housing estate?
A building is self-sufficient in terms of energy if the energy needed for heating, preparing hot water and providing electricity does not have to be supplied from outside. Therefore, it is the ability to independently meet the total energy demand by using your own, usually renewable sources.
Self-sufficiency means energy independence from external suppliers, which seemed unrealistic some time ago. Currently, in the context of self-sufficiency, we talk not only about single-family houses, but entire housing estates (the so-called green district). Due to the fact that such buildings are powered by renewable energy sources, they are also environmentally friendly (emission-free).
What are the advantages of a green housing estate?
Concern for the natural environment is an increasingly common phenomenon. Unstable energy prices and uncertainty on the energy market often keep us awake at night. These aspects are the reason why it is worth considering the self-sufficiency of the estate. Energy independence means:
- reduction of greenhouse gas emissions,
- lower bills and operating costs,
- no worries about rising electricity prices,
- peace of mind about the availability of raw materials.
Energy self-sufficiency means independence from price fluctuations and sustainable development. Renewable energy sources are environmentally friendly (plus you don't have to worry that they will run out one day). The use of renewable energy sources brings economic and ecological benefits, and according to many experts, it is also the future of energy management.
How to achieve energy independence?
Obtaining energy self-sufficiency requires combining three key elements. And more specifically:
- producing your own energy from renewable energy sources (e.g. photovoltaics, wind turbines),
- care for energy efficiency (including through the use of energy-saving solutions),
- energy storage (storing excess energy translates into stability of supply).
In the case of single-family houses, this is usually done using self-sufficient photovoltaics (off-gird), which does not require connection to the power grid. Thanks to this, the house produces electricity from solar energy and stores it, and then uses it on days when the panels cannot produce energy (during cloudy weather). In the case of on-gird installations, surplus energy is in turn sent to and received from the power plant when necessary. Energy self-sufficient houses are increasingly often entire housing estates that use only green energy.
How can settlements achieve energy self-sufficiency?
Achieving energy independence is a big challenge for districts. Existing housing estates must undergo a complete energy transformation. What should you do for this?
- determine the renewable energy potential for a given location (e.g. wind or biomass resources),
- develop an individual self-sufficiency plan,
- estimate investment costs,
- find a source of financing.
This is not an easy process. It must be taken into account that the administrative and legal management of the project itself is complicated. However, it is worth knowing that it is possible to achieve it, and not only green districts, but entire communes are being built in Poland.
Energy transformation tailored to your needs
A green estate isn't a fairy tale, but a real opportunity for savings, increased security, and environmental protection. Achieving this requires a personalized approach and an energy transformation.
