Institute for Renewable Energy and Efficient Exergy Use, INOVEKS, d.o.o. was established in early 2010 to provide counsulting on developmental projects in the field of energy usage – mainly focusing on efficient use of energy & implementation of renewable sources of energy into existent systems.
Our main focus when working on different projects is taking care of environment – and subsequently ensuring substantial consultingthat combines energy and environment. This approach enables us to ensure all-over lower energy usage and consequently reducing our dependence on exported fuels.
Renewable Energy Sources (“RES”) are our main medium main way of fighting climate changes that simultaneously contribute to economic growth, create new jobs and play an important part in ensuring safe energy future. These sources of energy are permanent – we can use them continually but we won't run out of them for the time of our existence – and this is their particular quality that makes them so versatile. Biomass, hydropower, wind power and geothermal energy are all renewable sources of energy. We continue to use more and more of renewable sources, but their effects will stay negligible if we won't learn how to use the most of this kind of energy efficiently.
Efficient Energy Use (“EEU”) is a term that describes taking steps/measures and using technologies that enable us to reach the same goals with noticeably less energy used. This plays an important role in ensuring safe energy future. Energy that comes from fossil fuels (oil, coal, gas) isn't limitless and causes side effects that are harmful to the environment to a great extent. Steps that ensure efficient use of energy can greatly contribute to lower energy usage, lowering emissions and therefore lessening the effects of global warming while keeping the standard of living at the same level. The main goal of »EEU« project is to lower the total of energy being used and subsequently lowering expenses used for energy in households as well as in economic sense.
Our name also includes the lesser-known concept of 'exergy.' The terms exergy and anergy were introduced into global literature in the mid-20th century by Slovenian scientist Dr. Zoran Rant, a professor at the University of Ljubljana and later at the Technical University of Braunschweig. These terms describe the convertibility of energy. Every form of energy consists of exergy and anergy, with one of these components potentially being zero:
Energy = Exergy + Anergy
Exergy is the part of energy that is fully convertible into other forms of energy. Energy can be categorized into three types:
- Energy that is fully convertible into other forms of energy (exergy): Examples include mechanical work, electrical energy, potential energy, and the kinetic energy of wind.
- Energy that is partially convertible into other forms of energy: For instance, heat.
- Energy that is non-convertible into other forms of energy (anergy): For example, the internal energy of the environment.
The First Law of Thermodynamics describes the conservation of energy, stating that the sum of exergy and anergy remains constant in all processes. It also teaches us that energy cannot be consumed but only transformed from one form to another, meaning that energy can be used but not spent or consumped.
The Second Law of Thermodynamics explains the irreversibility of processes. In all theoretical, reversible processes, exergy remains constant. However, in real-world, irreversible processes, exergy decreases as it transforms into anergy. Since all technical processes are irreversible due to the imperfections of our machines and devices, we must always account for exergy losses.
Therefore, the goal should not only be the efficient use of energy but also the efficient use of exergy!
