April 26 - Chernobyl Anniversary

Author: Haris Hadžibaščaušević

Exactly 35 years ago, an unprecedented nuclear catastrophe happened on April 26. Not far from the city of Pripyat in Ukraine, in the Chernobyl nuclear power plant, there was an explosion on reactor no. 4. The consequences of the explosion were and still are drastic - the abandoned cities of Chernobyl and Pripyat, which are today also called "ghost cities", contamination of land and environment, which is assumed to last for the next 24.000 years within a radius of 30 km, and all the damage cost the then USSR 18 billion Soviet rubles, ie. $ 68 billion.

In this regard we mark on this day World Day of Renewable Energy Sources, which aims to point out the need to research and application of renewable energy sources - water, sun, wind, geothermal sources, biogas, etc.

In addition to the aforementioned nuclear disaster, the world is facing another challenge, and that is the COVID-19 pandemic, which showed us what the world would actually look like if we turned more to clean and renewable energy as well as domestic resources.

What are renewable energy sources?

Unlike fossil fuels (coal, oil), whose reserves are limited and will be depleted over time, and the production process is lengthy and can cause catastrophes of appalling proportions, solar, water and wind energy is constantly around us and is renewable, making them thus renewable energy sources. In the past, renewable energy production was more expensive than that obtained from fossil fuels, because fossil fuels were thought to be more available, while solar, wind and water energy depended on other natural conditions. However, over time, the opposite has been shown, and with the combined use of the three mentioned energy sources, numerous advantages are beginning to be realized, and the most important one - they will never disappear.

Coal exploitation as an undermining of the natural system

One example of how coal mining is destroying a community's ecosystem is the Sierra Nevada de Santa Marta in northern Colombia, known for its biodiversity but also for the isolated indigenous peoples who live on it. Due to the growing number of quarries and excavations, the habitat of these peoples is endangered, as a result of which they are forced to change their way of life, saying that mining brings more poverty and more harm to everyone.

Quarries strip the slopes of the mountain, while coal mining in the Cesar region contributes to global warming, melting its ice peaks. Drinking water supplies are sufficient to meet the needs of all residents of this region, but because of the mines nearby, the water is often polluted leaving the residents without water, since corporations simply divert the river flow to the mines. Numerous small farmers have broken as river flows are diverted and coal dust from the mines creates impossible conditions for crops.

There are many advantages to using renewable energy sources, such as:

  1. pollution reduction, because the technologies used have less negative impact on the environment, the future is assured, because energy is constantly renewed;
  2. greater investment in the construction and maintenance of renewable energy facilities means more work and energy production, and less spending on energy imports;
  3. safety, etc

Bosnia and Herzegovina on World Renewable Energy Day

It is predicted that by 2035 our country should produce about 40% of electricity from renewable energy sources, and to achieve this goal, it is necessary to invest approximately 220 million KM in the construction of small hydro, wind, photovolataic and biofuel power plants, since our country possesses enormous potentials and natural conditions for that.

Therefore, this day is a reminder of the limitations and problems of the use of non-renewable resources, the importance of security of energy systems and smart management of energy resources.
