Energy Efficiency

How to use necessary energy in the most efficient way

Every day people use energy for transportation, cooking, heating, cooling, production, lighting, as well as for entertainment and many other purposes. However, the way in which all this energy is used significantly influences our environment and life. Therefore, it is very important not only if we are saving energy (whether we unplug appliances when we do not use them), but also if we are using it in the most efficient way (whether the used appliances and technology are energy-efficient products).

Taking this into account, we can distinguish two categories: saving energy and energy efficiency. 

Saving energy means everything that we do so as not to waste energy – these are simple steps that everyone can adopt as a way of behaving, from turning off the lights when leaving the room to recycling plastic or aluminum packaging.

On the other hand, energy efficiency is a term that refers to the use of technology that requires less energy – as a good example, energy-efficient light bulbs that consume less energy instead of traditional incandescents and give the same amount of light.

Why is energy efficiency important?

Although energy losses cannot be reduced to zero, they can be reduced in different ways using different techniques, and with a careful or efficient approach energy can be consumed in optimal amounts for some process or an activity. When used in an inappropriate manner, which means that there is a difference between the amount of energy supplied and the amount of energy required, this leads to wastage and thus to financial loss.

Inefficient use of energy is largely the result of poor design, inadequate operating characteristics of the process, poor maintenance, engine operating at idle or operating of the equipment when it is not necessary (lighting on, running the process at unnecessarily high temperatures and the like).

Additional benefits of introducing energy efficiency measures include:

– lower energy dependence,

– reduction of pollution,

– direct impact on improving living conditions.

How far did we go in the introduction of energy efficiency measures?

We could answer this question with the assessment that there is a long road ahead of us. Here is why…

* Energy consumption in Serbia is twice as high compared to average consumption in 35 OECD countries,

* In our country as much as 60 percent of final energy is spent by the building sector,

* The owners of flats and houses in Serbia mostly consider the proposed measures for energy efficiency only as an additional tax,

* Only 10 percent of domestic investors recognize energy efficiency as a possibility to gain competitive advantage over competitors.

Given that energy is the most scattered in industrial plants and in the building sector, this means that the greatest effect can be achieved in implementing the necessary measures for energy efficiency.

Bearing in mind that Serbia has the obligation to achieve the final energy savings of 9 percent by 2020 compared to the 2008 consumption, the National Energy Efficiency Action Plan has been established and Belgrade will soon have its own Fund for the Improvement of Energy Efficiency, which will launch a huge project for the improvement of energy efficiency in public and private buildings in the capital. Energy savings that could be achieved by introducing planned measures could be from 15 to 25 percent per household so as to maintain the existing standard.
