Considerations on energy transition

In the future, we will experience a continuously increasing energy demand mostly due to the continuous growth of the world population.Today we use fossil fuels (coal, oil and gas) in order to cover the society's basic needs. This involves significant CO2 emissions that contribute to the climate change by contributing to the increase of the global temperature. A great number of countries through international agreements are working on energy transition towards renewable energy resources targeting to a sustainable future. In reality though the path the world has to follow is still long and the transition towards a green future cannot be immediate. Some of the most populated countries still rely on coal as their main energy source while oil is still the most frequently used fuel in transportation. Furthermore, the passage to new energy sources would mean new facilities and new distribution networks that are not economically possible for many countries. In this energy transition natural gas can play an important role as the mid-point between traditional fossil fuels and renewable energy sources. It produces lower emissions than coal and oil, the facilities for its extraction and transportation already exist in many countries and can support the energy consumption needs of the modern society. In combination with CO2 capture and sequestration applications it can provide a realistic (greener) transition towards a fossil-fuel free future.
