Energy self-sufficiency – what is realistic?
Energy prices depend on many factors, and their fluctuations can be unpleasant. That is why the need to build energy independence is being talked about more and more often. What is it about? And on what scale is energy self-sufficiency possible? We explain which solutions are already available.
What does energy self-sufficiency mean?
An energy-self-sufficient building does not need external energy supplies. It independently produces the energy needed for electricity, heating and hot water. Homes that are completely independent often do not even require connection to the public grid. How it's working? One of the processes leading to energy self-sufficiency is the conversion of renewable energy (e.g. from photovoltaic panels) into electricity. The electricity obtained in this way can also power a heat pump that takes care of heating and domestic hot water. Independence means that this energy covers the daily demand for electricity and heat. For this to happen, in the case of electricity produced by a photovoltaic installation, it is necessary to store surpluses that will be useful on cloudy days.
Self-sufficiency and hybrid energy systems
Photovoltaics is not the only way to achieve energy independence. In the case of enterprises, institutions or entire housing estates, it is possible to implement other solutions that effectively support energy independence. An excellent example is those implemented by Veolia hybrid energy systems, i.e. systems combining various energy production technologies. Energy self-sufficiency in this situation, it is independent supplies of low-emission electricity, heat and cooling. What exactly does this involve? Below you will find the characteristics of key systems.
Cogeneration and trigeneration systems
Cogeneration is the process of simultaneously producing electricity and heat. This maximizes the use of primary energy and minimizes losses. Therefore, efficiency is increased, which leads to energy self-sufficiency. Electricity and heat are supplied continuously (even if there is a failure in the central distribution system). Cogeneration is a perfect solution for industrial enterprises, public institutions and even entire housing estates.
In a situation where it is necessary to provide cooling at the same time, a trigeneration system will be an excellent choice. What is that? It is a system that integrates three components: electricity, heat and cold. In this case, energy independence also results from own energy sources. Trigeneration will work well for companies and institutions that need electricity, heating and air conditioning, e.g. in shopping centers.
Hybrid boiler rooms
Energy self-sufficiency in the housing sector? Hybrid residential boiler rooms play an important role here. These are intelligent energy systems combining various energy generation technologies. They may include, for example, photovoltaic panels, heat pumps, gas boilers and energy storage. It is a comprehensive way of providing energy, heat and cooling that adapts to the needs of users. The hybrid system is flexible and economical, ensuring energy independence and reducing greenhouse gas emissions.
Hybrid boiler rooms are also used in business and industrial buildings. Such systems include gas and hydrogen boilers, solar panels, heat pumps, energy storage, fuel cells and hydrogen production electrolysers. All this means that they are able to meet the needs of various industries, including: shopping centers, hospitals and production plants.
Veolia supports energy self-sufficiency
Energy independence means a sense of security and a way to significantly reduce costs. Therefore, not only more and more households, but also enterprises, institutions and even local governments are moving in this direction. However, to implement this concept, a well-thought-out strategy supported by expert analysis is necessary. IN Veolia you will find many modern solutions, including an offer of hybrid energy systems. We provide comprehensive support during the energy transformation: from determining needs, through preparing the concept, selecting suppliers, installing devices and servicing the system. Gain greater energy independence and security of energy supply!
