 The use of fossil fuels as the main source of energy has caused negative environmental impacts such as global warming and air pollution. These problems have led to international agreements and local policies aimed at avoiding global warming consequences. However, there is a depletion of non-renewable resources which may be scarce or non-existent in future generations. The preservation of resources is not being accomplished nowadays. In this work, the calculation of indicators and mathematical and statistical analysis were applied to clarify trends and increase public awareness. It was found that many European countries still depend heavily on fossil fuels, with significant differences in gross inland consumption per capita. By 2050, it is estimated that only approximately 14% of oil-proven reserves, 72% of coal-proven reserves, and 18% of gas-proven reserves will remain. Given the small reserves of European countries on fossil fuels, if they need to use them, they will fast disappear.
