This contribution aims to give an overview of the current energy situation and suggest some sustainable energy alternatives. First, a brief history of the raw materials used for energy production is presented over time, with a high dependence on fossil fuels, since it has been estimated that more than 90% of the energy consumed comes from non-renewable resources such as oil, gas and coal. It is also mentioned that oil is undoubtedly the main source of energy used today and therefore its reserves are inevitably depleted. In addition, it causes and increases environmental pollution problems. Subsequently, it is suggested that in order to achieve energy sustainability, it is necessary to develop alternative sources that can reduce the emission of greenhouse gases (GHG) that are toxic, as well as reduce water use and decrease energy production costs. One of the alternatives proposed is the production of biofuels such as biodiesel and bioethanol. Their main characteristics are cited in terms of raw materials used and production systems. Finally, some solutions are suggested that are being developed worldwide to address the current energy situation.
