Between the speech of world leaders and the practice there is a big difference. The dependence that the modern world has on fossil fuels is alarming and this is evident with the continuation of the war in Europe, which causes the cost of energy to skyrocket across the planet and compromises all global supply, logistics and production chains, strongly linked to the cost of energy. If it weren't for the zero COVID policy in China that puts Shanghai and Beijing under lockdown and reduces the Asian giant's appetite for energy, the energy crisis in the current global conjuncture would be even worse. Global inflation is a reality today. The directives of several countries favoring the electrification of motor vehicle fleets only aim at the tip of the iceberg. Without a global policy to replace the use of fossil fuels with sustainable and renewable energies, global warming will remain an ever-present concern.
