Energy plays a fundamental role in our societies and in our daily lives. Lighting systems, machines in offices, household appliances and electronic devices work thanks to electricity. Transport, and therefore trade, are made possible by oil-derived products. Industry depends on energy supply for its activities, as does agriculture. In short, without energy we would not be able to carry out the simplest activities: taking a hot shower in the morning, preparing breakfast, taking the children to school by car and then working on the computer, possibly in a suitably air-conditioned office. That is: energy is a key prerequisite for our daily life.
Energy resources underpin the development of the international orders of modern history: coal was the backdrop for the British Empire in the 19th century, oil was at the centre of the next “American century”, and today many people predict that China will become the world’s renewable energy superpower of the 21st century. In summary, we can say that the strategic importance of energy is such that it defines global economic and geopolitical dynamics.
In the last twenty years the global role of energy has become even more central as a result of the growing international awareness of two major issues: climate change and access to energy in developing countries.
Global energy supply has always been, and continues to be, largely based on fossil fuels. Despite the recent development of renewable energy, 80% of the world’s energy supply is still derived from coal, oil and natural gas, the combustion of which produces around 75% of global greenhouse gas emissions, making energy the main cause of climate change. A structural response to this serious threat to humanity can therefore only come from the energy sector, in particular through a global clean energy revolution.
As energy is a fundamental prerogative of modern life, ensuring access to it is of crucial socio-economic importance. Today, 860 million people around the world – and particularly in Africa – still do not have access to electricity, while 2.6 billion people still do not have access to modern and safe cooking systems. The latter is a dramatic problem both from a social and health point of view (think of respiratory diseases caused by smoke inhaled at home from stoves or fireplaces) and from an environmental point of view (think of deforestation resulting from the use of wood for these purposes). Enabling these people to benefit from modern and economically sustainable services is one of the major socio-economic issues of our time, a necessary step towards eradicating poverty and reducing inequalities.
The enormity of these challenges presents us with the need to have a clear understanding of the fundamentals of global energy in order to launch an informed public debate on the vital issues of the climate crisis and its possible responses.
This need is even more pressing today given the centrality of the issue of energy transition on the international political agenda. The European Green Deal is, in particular, the most avant-garde experiment in this field in the world to date. With this initiative, aimed at making Europe the first climate neutral continent by 2050, a new trajectory is being set up to accompany the energy transition with the necessary economic and industrial transformation it entails, guaranteeing the social inclusion of the entire process. With its Green Deal, the European Union has in fact acknowledged that climate and energy policies alone are no longer sufficient to meet the scale of the climate challenge. Only a much broader policy – also taking into account economic, fiscal, industrial, labour, innovation and social policy issues – can address this challenge in a balanced way. The question is simple: to ensure that climate change does not compromise our lives and those of future generations, a clear change of pace is needed. What we are going to live through, perhaps without really realising it, is more than just an energy transformation. It is a real industrial revolution, which will touch every aspect of our economic systems and affect the way we live and relate to the environment. It is a challenge that can really make the world a better place for everyone, but for this we must be prepared.
