Mankind has been using energy from its beginnings. Over thousands of years, energy has made people's lives easier in countless ways, which is especially evident today when we have many devices such as cars and smartphones that make our lives easier. In order to function, these devices need energy. Throughout history, the energy industry has successfully met this growing need for energy. The problem is that fossil fuels were primarily used to obtain energy, which have a negative effect on society, and especially on the environment. That is why the energy industry is the source of many development challenges today, mostly because of these negative environmental consequences. This is where the concept of sustainable development appears, which attempts to manage development challenges on a global level. The fundamental idea of sustainable development is to leave the world in a better condition for future generations than it is today. The key element in this is the fight against climate change and pollution by switching from fossil fuels to renewable energy sources. This transition from harmful fossil fuels to renewable sources is called the energy transition, and it is in full swing today. Although fossil fuels are still the most common source of energy, things are changing for the better. Their share is slowly decreasing in favor of renewable sources. Thus, in the last 10 years, the consumption of fossil fuels has stagnated, while renewable sources, especially solar and wind energy, have achieved enormous growth rates. The revenues and profits of the oil and energy giants, with some annual fluctuations, are also declining or stagnating. On the other hand, renewable companies achieve growth year after year, while at the same time having a positive impact on the environment. That is why the oil and energy giants are turning to renewable sources and making significant investments in renewable sources and green technologies and announcing new ones. Sustainable development is slowly turning the energy industry towards sustainability, where the former source of the problem is becoming its solution.
