A new environment is emerging in energy with two fundamental changes, affecting both the energy model and energy efficiency. As far as the model is concerned, the energy mix changes dramatically with the increasing participation of renewables and the use of natural gas as a transitional fuel until carbonization. This change is due to the impact of climate change and, at the same time, to the increased demand for electricity (it is evident that many sectors will be further electrified, such as automotive). Technology has empowered the consumer to become a Prosumer (Producer+ Consumer), that is, a consumer who produces his own energy, in addition to consuming it. Therefore, we are now moving away from a traditional model, where the emphasis was on the supply side, towards an model with emphasis on demand (when, for how much and at what price the consumer will “buy” electricity).
The second change concerns the importance of energy savings based on energy efficiency. More specifically, the increase in energy efficiency is achieved: (a) when the same level of energy consumption achieves a higher energy efficiency or (b) when the same efficiency is achieved with lower energy consumption. There are various technological solutions (eg lighting, cogeneration, net metering) to increase efficiency. Saving energy is also a matter of attitude. The cleanest and cheapest form of energy is the one we save by making proper use of technology, covering our real needs without waste and with respect for the environment.
