 The main source of energy for most countries is fossil fuels, which has caused negative environmental impacts such as global warming and air pollution. Air pollution causes health problems leading to social and economic negative effects. International agreements have been established to avoid global warming consequences through local policies adapted to each signing nation. However, non-renewable resources are being depleted and not being preserved, which is a common goal of the circular economy strategy and sustainable development. In this work, indicators and mathematical and statistical analysis were applied to analyze fossil fuel energy consumption, depletion, and their relationship with other variables in 29 European countries. The results showed that many European countries still depend heavily on fossil fuels, but significant differences were not found 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.
