Energy is necessary for the survival and well-being of humanity. After millennia of scarcity, for just over two centuries, we have had relatively cheap energy, based on fossil fuels. Today, three main causes are driving the energy transition towards renewable energy sources: on the one hand, pollution produced by the intensive use of fossil fuels, as well as the unsustainability of their consumption; on the other hand, technological advances in the production and use of electricity as an energy vector, which far exceed the possibilities of, for example, combustion engines; and finally, the lower cost of new renewable generation technologies.
The energy transition is going to be a real revolution. New energy technologies, accompanied by information and communication technologies, will profoundly change industrial and urban environments and mobility.
