Today, electricity is considered priceless. However, the era of fossil fuels is undoubtedly ending as the resources are running empty and with that, people will be forced to find new, renewable sources - a key source being water. Hydro energy is a very important energy source and a huge advantage to the world's power supply. Slovenia itself has a very rich tradition of building hydroelectric power plants. A good example being hydroelectric power plant Fala that has been around for over a hundred years. Building those facilities on Slovenian ground has been in progress since before, during, and after both world wars. Since then the resources have been diverted towards renovations and upgrades on already standing facilities. With that, the amount and the quality of electric power have increased. An important fact is that almost all of the work done has come from Slovenian contractors. As abovementioned, hydroelectric power plants are one of the most important power sources in the world and in Slovenia as well. That aside, many studies report a very low use of the water potential in Slovenia, estimating it to only a half. There are many unused creeks and smaller rivers that could represent a large contribution. Slovenian history is a beautiful representation of the way how to exploit bodies of water, since there had been almost five thousand dams used for mills, saws, and forgeries. These bodies of water could be restored and used as micro hydroelectric power plants. The largest problem is the time-consuming process of placing these power plants. The construction of a micro hydroelectric plant takes about a year. It takes ten years to get from the initiative to the beginning of the building process. Comparing Slovenia to Austria where the same process takes only half a year. Slovenia has a contract with the European Union and is, therefore, obliged to reach 27 per cent of renewable energy in final gross energy consumption. In addition, it is a fact that power use is increasing. The world strives for renewable power sources and sooner rather than later people will be forced to strategize and compromise to achieve their goals.
