*Introductory Chapter: Trends and General Information on Energy Policies in the World*

This book discusses the current world situation regarding the existing energy policies. The interest in energy sources and energy data for renewable energy sources are presented and the energy distribution shares are clearly shown in detail. The biggest problem in energy policies is still the investment cost. Currently, materials and systems of energy systems occupy a significant place in energy conversion.

In this section, it is necessary to determine the global energy targets as well as the current energy data. Energy policies should be considered in the short-term as well as long- and medium-term plans. In short, countries have to take all kinds of measures in their energy policies and wars, turmoil, government stabilization, and

Accordingly, in order to shape the world of, the future, 2050 and beyond, arrangements should be made by taking into account the data that can shed light on

The increase in geopolitical tensions as well as many other uncertainties such as the oil crises in the world affect the energy policies [13]. In addition, precautions must be taken urgently for emissions-particles and other key factors released during energy production. While energy policies affect these phenomena mentioned above, energy investment costs and system installations are other factors. In addition, disagreements, unrest and wars between countries directly affect energy

Due to key factors, when it is evaluated in terms of countries, it is necessary to reveal what should be done in energy policies in the coming years. Laws and objectives should be regulated accordingly [13]. Governments should focus on sustainable energy resources and sound steps should be taken forward. Stability and order can only be achieved through the establishment and implementation of good energy policies. The energy history chronology and future energy scenario are presented in **Figure 6**. In 1919, energy consumption was only 1500 Mtoe, while in 2018 it was 14,300 Mtoe. In 1919, only wood, coal, and small amounts of oil were consumed,

### **4. Results and discussion**

In this section, it is necessary to determine the global energy targets as well as the current energy data. Energy policies should be considered in the short-term as well as long- and medium-term plans. In short, countries have to take all kinds of measures in their energy policies and wars, turmoil, government stabilization, and human rights into consideration.

Accordingly, in order to shape the world of, the future, 2050 and beyond, arrangements should be made by taking into account the data that can shed light on energy policies.

but in 2018 this changed completely. In 2018, petroleum was the first, followed by natural gas. Immediately after, coal and natural gas consumption are listed. Interest in renewable energy sources has also increased. In the 2040 forecasts, petroleum and natural gas are in the forefront, while coal and renewable energy sources are visually equalized in terms of consumption. It is foreseen that the consumption in nuclear energy may be considerable [13].
