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

This book indicates the policy of energy in the world. Energy wars continue to occur due to the energy policies of the countries in the world. Energy policies in recent years have a direct impact on the development of countries. Countries are taking steps towards existence by producing short, medium and long term energy strategies. It is also explained in the concluding section on how energy in the

There are many factors in the decisions and measures taken regarding energy policies. It is clear that it will play a key role in global warming, as well as the factors that will affect countries' investment costs, geopolitical locations, emissions, and

In **Figure 7**, the energy efficiency now and future energy scenario in the world are emphasized [14]. There has been a decline in the energy consumption curve starting from 2010. According to the forecasts of 2050, energy density ratio is expected to increase while per capita energy consumption decreases. By 2050,
